Canon EOS 7D

Can I get this classic EOS 7D operational again? It has damaged card reader pins.

I received this camera from a good friend who is a professional photographer, a few weeks back in a bundle of cameras and photographic equipment he no longer uses, he has kindly donated them to me to get working again. You can see that post, and just what was donated here: Cameras…i need more!

I’m in a situation where I don’t have my repair gear with me at the moment, as it is all packed and in storage awaiting our impending house move. Hence the reason I am racking up a whole load of draft posts that I can’t complete until I have my workspace back in use. Therefore any work I can do is severely restricted to inspection, cleaning and preparation with the only maintenance being attempted on the outside of the camera.

Let’s have a brief history on the Canon EOS 7D:

The Canon EOS 7D is a high-end APS-Cdigital single-lens reflex camera made by Canon. It was announced on 1 September 2009 with a suggested retail price of US$1,699, and was marketed as a semi-professional DSLR camera.

Among its features are an 18.0 effective megapixel CMOS sensor, Full HD video recording, its 8.0 frames per second continuous shooting, new viewfinder which offers 1.0X magnification and 100% coverage, 19-point auto-focus system, movie mode, and built-in Speedlite transmitter.

The EOS 7D remained in Canon’s single-digit APS-C model lineup without replacement for slightly more than five years—the longest product cycle for any EOS digital camera. Its successor was the Canon EOS 7D Mark II, announced on 15 September 2014.

Structurally and cosmetically this is a beautiful camera in very good condition. However it would not have been donated to me unless it had problems. Let’s now put my detective hat on and go looking for clues.

Assessment:

As stated earlier, cosmetically there is nothing at all wrong with this camera, it even has the plastic screen cover in place. Mirror looks clean and curtain looks fine no issues here. All electrical contacts such as HDMI are in good condition with no visible damage to the ports.

Everything is fine, cosmetically, externally.

One last place to check and I now believe this is where the problem lies. This is the CF card door, and when opened it reveals one possible big issue.

Bent pins on the CF card reader. These pins are quite small and only millimetres in diameter, in a very restricted space about 8 cms deep and 6cm in width, it really is quite a small aperture. There are two options here, one I try to gently coax these pins back into place with a fine point tool, however the pins are minuscule, and brittle and prone to breaking. I can see potentially 7 pins that are out of position, not an easy or expedient option. But I’ll have to give it a go. Option two is to purchase a new CF card reader replacement, this option carries some expense and quite a complex dismantling of the camera to achieve said replacement. Needless to say I will initially attempt the pin bending procedure. Pending on success or failure, i could venture into step two. Read on to see what occurs.

Repair:

With a fine point set of tweezers, I’ve decided to have the first attempt at seeing if I can straighten the pins. Using a bright LED torch I angle the beam slightly so I get a bit of shadow on the pins, and this allows me to see how many are bent. I can see seven pins in total that are bent, and two of these seem as if they have been forced down to about half their height. This is quite normal when people go in a bit heavy with the CF card, if these pins go down too far there is no option but to go inside the camera and push them out from inside, or replace the card reader completely. I kind of hope that I have been able to pull them out far enough for them to work. I won’t know though until I get the CF card and batteries out of storage.

I’ve spent about an hour, bright lights, little subject matter, and now have very tired eyes. I’ve been breathing slowly just like a surgeon heading into a part of an operation that requires the utmost concentration, and precise and very delicate movements. I think I’ve done a good job. Only testing will tell.

Speaking with my friend Jon, who this camera came from, he has stated that he rather foolishly lent this camera to a ham fisted colleague who hammered the card into the camera, causing the issues that I am dealing with today.

If we have to open up the camera, I will probably be looking at about 3 hours of work, as there is an awful lot of dismantling that has to occur, and I believe there are around 30 screws to remove just to get under the skin of this camera. It’s built like a brick, weighs about the same and is just packed with electronics.

Fingers crossed 🤞 let’s hope option number one has been successful.

Well, today I went to the lock up and dug out a small 2GB CF card and the two Canon batteries and a charger. I came home and Put the batteries in that surprisingly still held a little charge, sufficient to turn the camera on. I gently inserted the CF card only for the following message to appear on the screen, “Card cannot be accessed. Reinsert/change the card or format card with camera.” Aww shucks I thought, it hadn’t worked. I tried to format the card and the format failed, at this point I thought the pin maintenance had not worked. Damn. I was a tad annoyed.

So I removed the card and checked the pins, they were ok. I reinserted the card and the same fault appeared, however this time when the option came up to format the card it worked. I was so shocked I tried it again and forced another format, again it worked!

Right it was now time to get a lens on the front and test the camera to check to see if it would write to the card, it’s only a stock lens, nothing special but absolutely fine for testing purposes. Just walking around the house I put the unit into auto, the flash popped up and I proceeded to rattle off a few random shots. And it worked, the results all came up on the rear screen.

To say I was pleased at this is an absolute understatement. The work on the pins has worked and I now have a perfectly well working example of quite a top end camera. There’s no doubt that in the future the camera will require a replacement card reader, but for the moment it’s been given a new lease of life, and whilst I remember to be gentle with the removal and placement of the CF card, let’s just enjoy the camera and its capabilities until that time comes. In the meantime here are just a few, “Randoms” taken to test the card and camera in and around my home.

Result:

Time to give this camera a little buff up. (Clean)

This unit only appears to have taken 1,860 pictures. It is completely unused, and in perfect condition. And it now works. To be honest I feel more confident with this camera than I do with the mirrorless Sony that my wife purchased for my birthday. This was going to become my number two camera, however it’s just been promoted to my number one, as long as that card pin issue and repair holds up, and I have no reason to doubt that it should be a long time before any issues arise. I am confident that my repair has longevity as they say.

I want to give it a good test in daylight conditions in all modes rather than auto. I want to get a bigger CF card maybe a couple of 8GB ones, I don’t see the point in going for the bigger cards just in case there is a read/write issue in the future. It’s just an OCD thing for me, you know what I’m like.

So overall I’m really quite happy and satisfied with this camera. Of all the cameras I was gifted by my good friend Jon, all have been repaired apart from one that was beyond economic repair, even that has been broken down into it component parts, every screw recovered and will be used for spare parts. Nothing, and I mean nothing has been disposed of from this collection of cameras and accessories.

That’s what I do, I don’t waste anything. Ask the wife!

Many thanks for passing by, it’s always very much appreciated.

Canon EOS 3000

Another entry level camera, unloved, made good

Here I have another basic, entry level camera made by Canon. Produced around 1999? this camera is probably around 26 years old. These cameras don’t have the traditional identification number printed within the film spool holder that the older cameras had, hence the precise manufacturing date is difficult to confirm.

This is a camera passed onto me by a good friend and professional photographer, Jon, as can be seen in this post: Cameras…i need more!

Here’s a little information about this camera:

The EOS 3000 is an autofocus SLR for 35mm film introduced by Canon in 1999. It was sold as the EOS 88 in Asia. (It was not sold in the US.) The pentamirror viewfinder and manually-activated popup flash helped keep this a lower-cost model; but a full range of autoexposure modes were included, including off-the-film flash exposure setting. Film transport is motorized and the camera requires two 3-volt CR123 lithium batteries to operate.

A compact, lightweight, low-priced SLR camera. Successor to the EOS5000, but with greatly expanded basic functions. The camera incorporates the Mode Dial and most other basic features of the EOS Kiss/EOS REBEL XS/EOS500 and includes six-zone evaluative metering linked to three focusing points. In addition, the flash is linked to the measurement point so that during shooting the flash out-put level is constantly adjusted for optimum exposure control. For reasons of cost, the flash unit is manual pop-up/retractable head type. The EOS3000 is compatible with system accessories for the Kiss and New Kiss. The high-quality design has a feel of genuine elegance.

Canon/ Camera-wiki.org

This camera was pitched at a low cost to attract people into photography, and to encourage those who were just hobbyists to upgrade to something more than the traditional point and shoots/disposables available at the time.

There is not a lot wrong with this camera as far as I can see, let’s have a look and do some tests.

Assessment:

It has a grip that’s starting to develop the sticky issue so that will need cleaning. The mirror and prism are dusty and will need a cleaning.

Overall the condition is very good, again this was a training camera, and seems to have had a quite low usage, as there is no scratches or marks. And only one dink as such. That dink happens to be the right hand strap holder that has been bent down to a point where the rear case does not open completely, it restricts its full movement.

Strap holder bent, restricting door opening

Top and bottom of camera look fine, no bleed on the LCD screen that is always a good sign

Battery chamber is clean and there is no contamination. This camera takes two 3v Lithium CR123A batteries. Let’s put two in to see if we have any life.

With the batteries installed we have a good display on the screen with no pixelation and it’s nice and clear. I install a roll of test film to see what happens. This camera winds the whole film onto the take up spool and winds back one exposure at a time. The take up when the door is closed works perfectly.

I then operate the shutter, to fire off the 14 exposures, all viewfinder indicators are good, with my 28-90 EF lens attached it focuses well and fires well. When the last exposure has been taken the film rewinds as expected with no issues. In reality the camera is working very well with no internal issues.

Repair:

First the dirty stuff. Let’s get that goo off of the sticky grip. I use my IPA and lint free cloth method that I posted about in a previous post here: Sticky, Rubber camera grips. This one is actually worse than I thought and has taken four applications to remove the deterioration on the grip. It feels a lot more pleasant though now that it is done.

The dirt from this grip can be seen on the cloth. Each black blob is one application

The issue with the strap lug restricting the door movement. Quite simply, a gentle movement with a pair of pliers was all that was required. Gently does it as these parts are brittle and easily broken. Don’t over do it, give up when it looks right.

A little gentle coaxing was all that was required

I’ve checked the film pressure pad and this is fine, there are no sharp ridges and the light seals are good. I don’t expect them to be bad as in theory they are not that old, they are in a good healthy condition.

I have cleaned the prism and the mirror with a swab and they are now fine. Using a B setting I have opened the mirror and curtain and used some compressed air to clean throughout. A brush blower was used with the curtain closed to clean around the film spool area and back plate. A quick final blow of the mirror and the aperture is then sealed with a cap to insure no further dirt and dust gets into the internal parts of the camera.

The final action is to use some cockpit polish to finish off the exterior of the camera.

Result:

I’ve cleaned the exterior and used some ceramic cockpit polish to finish it off, I must admit it’s looking very good.

Here I have yet another nice little camera packed with features that will make a great camera for someone to learn the basics of traditional photography with. However, it’s remaining in my collection for the while.

It’s yet another camera that I need to test, another one that needs to have a film put through it for its final test, however I am 100% confident of it’s capabilities and the fact that it operates just fine and all its settings, buttons and controls are doing exactly what they should. When I do get to put a film through, I will link to it here.

Another successful restoration and return to use of another old camera that had been put to one side. Not that this one really required a lot of attention, just a bit of servicing and tlc.

Thanks for passing by. It’s always very much appreciated

Canon EOS 5D MK2 assessment and repair

Last Updated: 25/4/24

This will be a running repair with regular updates. There is quite a bit going on.

The bargain basement DSLR has arrived (See original blog post here: Canon EOS 5D Mk2) and I’ve been able to give it a quick once over. It’s not had an easy life and has taken some bangs and knocks. Other than that it’s about 16 years old and has had about 69000 actuations, I don’t think it looks too bad personally. I’ve spent a good hour just giving it a good clean up and it was filthy, all knobs and buttons are working fine, the shutter isn’t locked and when a lens is attached, manually it all focuses just fine and the screen looks clean. There is no evidence of damage to the curtain however I can’t test this further until the battery and charger arrives.

To be honest if I can get this working it will be going into my own personal collection. As long as I can get some nice results I’m not that worried about how it looks cosmetically. The body can be touched up or I can add a skin, we’ll see how it goes.

Update: 6/4/24

I’ve now received a couple of bits consisting of two new batteries and a charger as well as a new battery door cover. Once powered up all indications, buttons, sensors are working and TTL indications are displaying as they should.

All lenses are working and moving and focusing as they should. The real good news is that the shutter fires at all speeds and is not stuck, and the sensor cleaner appears to be working.

I’m really happy with what I have found so far, I need to get a CF card to check the original issues that were reported with the suspect sensor. If that is the only issue I will get one ordered and install that at a later date. I have cleared all settings and the firmware is up to date. I’ve downloaded a raft of Canon software so I will be able to test this all once I get that CF card that should be here in a few days.

23/4/24

The CF card adapter has arrived from China. I’ve purchased this type as this particular adapter allows an SD card to be utilised in CF form. I have ample SD cards in use all around so this makes sense for me, I have nothing apart from this camera that uses CF cards so for a relatively low outlay this is the best option for me.

Now I have Every thing in place to test the camera. I’m using basic settings and an old test lens so I’m not looking for any spectacular photos as that’s not going to happen here. I just want to see what’s going on.

What happens most of the time

When I’m taking a shot everything lights up ok. Indications are all good, the shutter fires but all I see is a pinkish screen as demonstrated in the small video above. However every now and again I do get a “proper” photo, usually only the one then you have to turn the camera off then on again to get another and that’s not always guaranteed. As you will see in the two photos below you can get one photo and then the next has a pink band appearing from above.

Whilst taking a random photo looking at our ceiling, I became aware of what looked like a water leak by the chimney stack. This gave me some concern but I needn’t have been worried as it appears in other photos and is more than likely an Abberation mark on the sensor. The two pictures below show that mark on the sensor in the same area.

Occasionally the pink line that appears at the top of the photo also takes on a pixelated test card look. The weird thing is that if you put the camera into video mode the image is clear with good sound and no playback issues. Strange 🤷‍♂️

It really is looking as if the issue is around the sensor that in this camera is a CMOS sensor. But before I make any decisions on what action I’m taking I’m exhausting all the obvious issues if I can. I have looked at several forums on line and there are a multitude of tasks I could try but it all seems to filter down to two in general. A full camera reset and a reinstall of the last issued firmware.

Now I have completed the full reset and on top of this I’m going to install a new CR1616 CMOS cell, as I just don’t know when this was last done.

The CMOS deterioration rate is about 3% of the battery value per year, now if this camera was purchased around 2008 when they first came out then it dosen’t take a mathematical genius to work out that the cell could be sufficiently depleted. In fact I don’t know why I haven’t used the multi meter to test it🤦‍♂️

I’ll get on to that and will report back. It kind of makes sense seeing the sensor on this camera is a Cmos sensor. All tested, battery was at 2.3v, I have now replaced the battery but everything is still the same. I don’t know if updating the firmware will assist in any way, but I’m just following a procedure that most who have been in this position before have also done. it’s just a process of elimination before doing a full tear down of the camera. And if I can do anything to avoid that I certainly will.

I’ve finished all the testing and it is certainly looking like the Cmos sensor needs replacing. I’ve done all I can here, but I’m reluctant to order the new sensor from China as I’m not 100% confident of having the facilities or time to do the work required. Will I gain anything after the outlay? I very much doubt it. I’m going to move this camera on now with all my findings and hopefully I can find someone who will be able to take this project on to a successful completion.

I know parts wise I can make a good profit on the original outlay so maybe that is the route to take.

So I’ve failed on this renovation, but nothing is going to waste, it just needs to go to some who is somewhat more experienced with these type of upgrades than me. Hopefully I can gain some experience along the cheaper more available stock route.

I have learned some interesting things about this camera and it’s operating. So in many ways that’s a win, knowledge is everything.

Something to be getting on with..

The batch of cameras I purchased the other day, all old SLRs / DSLRs have now arrived… with a bonus.

I was expecting 10 cameras but I’ve trumped that with 12 and a lot of spares as well. The guy I purchased the Nikons from has thrown in two more D70 as spares, with loads more spare parts. He was having a clear out so I guess he’s funneled that stock my way…thanks old chap.

So I have received today

One Canon 5 SLR – stuck mirror, missing some small Connection covers and like a lot of these old cameras has a sticky rubber covering that was well known back In the day.
One Canon EOS 50E – damaged curtain, faulty lock and again sticky.
One Canon EOS 1000F – cosmetically sound no other visible issues.
One Canon EOS Elan 2 – cosmetically sound, just sticky.
Two Nikon D70S DSLR – missing battery covers and some other small accessory covers, both sticky.
Six Nikon D70 DSLR – all missing battery covers, or other accessory covers, one missing a CF card reader and all sticky.
And two sizeable bags of D70/D70s spares

I’ll be starting with a good clean to get rid of that stickiness and then I’ll power each up individually to see what other issues lie in wait. I’m hopeful I can get most of them up and running, I’m confident that the majority of the DSLRs will be repairable.

I’ll feature the repairs once I’m in a position to donate the time to them. I’m a busy boy at the moment what with work and the wife’s growing list of things that need doing around the house.

Canon EOS 5D Mk2

The assessment and repair of this camera can be found here: Canon EOS 5D MK2 assessment and repair

As the listing stated:

Canon 5D Mark II DSLR Camera – Body Only – Spares or Repairs

We have tested this camera and found the following fault:

The camera powers up, however the sensor is damaged and images are recorded either blank or unusable, and so we are describing this item as FAULTY / SPARES / REPAIRS.

Shutter Count: 69,970
EBay

I noticed this 5D on sale earlier for £109 Gbp. It’s from a supplier who has a good reputation who I have used before, however he suddenly drops the price by 90% and I snap his arm off for this. It has sensor issues and that’s at least a £70 price just for that part. Considering how much these cameras usually retail for it’s a price I could absorb…but I think something else must have come to light for him to change his pricing. The body is pretty beaten up, again I’m not too bothered with that, the usb port might be damaged by the looks of it and again that’s something I can sort.

I guess I’ll just have to await its imminent arrival. In any case for a total of £9.99 GBP I’ll make more from this just for spare parts.

See the assessment and repair blog post here: Canon EOS 5D MK2 assessment and repair

Canon EF lens 35-80mm

As the listing stated:

Needs opening cleaning and fixing sounds like something loose so selling as a repair project cheap.
EBay

No error code so in theory this should be an easier fix, however the fact that something is moving about inside tells me there could be more wrong with it than expected.

I now have the lens in front of me so here is what I can see.

Shake rattle and roll

Well, it certainly does rattle, something quite significant is moving about inside. When Connected to a camera you can’t focus or zoom so something in there is restricting movement. There is also fungus on the lens so this one will need to be carefully dismantled and cleaned throughout.

About 10 small screws later I am into the internal parts of the lens and the cause of all the rattling becomes apparent. A piece of the internal zoom mechanism has broken off stopping the zoom from smoothly operating through its range.

The part of the barrel that the item had snapped off was broken due to forceful action with the previous owner. There are two options here, junk the lens or see if it can be saved, I went for the latter. I mixed some epoxy resin and fixed the piece back into place also gluing it to a part of the mechanism that was not liable to hinder future movements. I left this for a couple of hours to cure.

Whilst waiting for the glue to cure I used a mixture of water and hydrogen peroxide to clean all the lens elements. I thoroughly dried them and gave a quick polish and reassembled them into the casing. The glue was dry now so I was careful to reassemble the lens not damaging any ribbon cables or contacts along the way. The lens looks lovely and clear of any fungus now.

I’ve put the lens onto a test camera and it’s fantastic. I couldn’t get focus when I unpacked the lens but now I have the full range of action and a lovely clean working lens for very little outlay and probably just 2 to 3 hrs of maintenance. Well worth it in my opinion. I wanted a good cheap lens to test my old stock and I now have one that I can easily sell on at some point, on top of that I’ve learnt a lot from working on one of these lenses. I’m certainly going to attempt working on more in the future.

Thanks for passing by. Always appreciated.

More stock

I’ve spent the grand total of £91 GBP on more damaged/faulty stock today, I now have enough stuff to be working on to keep me busy for months.

On top of the 6 Canon cameras I purchased last week I now have a further 4 Canon film cameras ( Eos Elan 2, 50E, 1000fn and an Eos 5) I’ve also got two faulty EF lenses to test the old Canons with, these will also get the repair treatment.

I’ve also purchased four Nikon D70 and 2 Nikon D70S units all needing the repair treatment, I’ve even blagged some spare parts here as well so overall it’s been quite a good days shopping.

More cameras to keep me busy

Did I overpay?

I have just purchased 6 untested ( probably the polite way to say totally useless) cameras from the late 80s.

I ended paying out the equivalent of £6:17(GBP) per unit. That’s inclusive of delivery and costs as well, not too bad really and if I can repair (if needed) I should still be able to move them on at a small profit. But I may also be passing these onto a local charity that teaches photography to youngsters and disadvantaged people in Leicestershire.

I have purchased a job lot of Canon Eos 650/600 cameras from quite a reputable seller who specialises in old film cameras.

I have 2 Canon Eos 600 units that date from 1989. These have motorised film advance and rewind, and are able to reach 5fps in one shot Af mode. Shutter speeds range from 30 sec to 1/2000 sec, with B mode. X-sync is at 1/125 sec. Powered by 1x6v 2CR5 lithium battery.

I also have 4 Eos 650 units.

The Eos 650 is the camera responsible for the first photograph used on the World Wide Web when a photo of the band “Les Horribles Cernettes” was taken on 18th July 1992 by photographer Silvano de Cennaro.

This camera was produced in 1987 and was the first of Canons Eos (Electro-Optical System) ushering in a new era for Canon cameras. The shutter is electronic, vertical metal focal plane capable of 30 sec to 1/2000 sec exposures as well as having 1/125 sec exposure with a flash. Also powered by 1x6v 2CR5 lithium battery rated for up to 100 36 exp rolls.

Both types use the Canon EF mount.

I’m happy from the pictures and knowing the sellers reputation that these units are cosmetically tidy, fingers crossed they don’t need a great deal doing on them but you never know. When they arrive I will do an assessment of both cameras and create a post accordingly.

Until then stay happy, stay safe and take care.
