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!

Canon EOS 7D

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.

Wikipedia

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.

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

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.

The camera in question

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.

CF card being installed

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.

Random shot 1
Random shot 2
Random shot 3

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:

You little beauty

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 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.

CF SD adapter

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.

Replacing the cmos battery

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.

More Camera statistics

Back in March 2023 in the early days of this site I threw some figures out there regarding the amount of cameras on the planet up to and including 2022, you can read that post here: Vintage Camera figures

In this post I’m going show a graph and some figures regarding the decline of DSLR ( Digital Single Lens Reflex ) in the last 12 yrs.

It’s becoming obvious that people are ditching the traditional camera frame for the mobile phone and tablet approach and the figures you see in decline for traditional cameras have probably gone in the total reverse and multiplied many times over for the latter. It hurts the brain to realise the total amount of picture capture devices out there, as well as the waste that this produces as a result of what has become a throwaway society in which we all must share some guilt.

I can honestly state that in the last 12 months I have purchased close to 60 Cameras, 18 radios about 14 portable cd and tape players and not one of them has been disposed of much to my wife’s displeasure. (To be honest she’s very supportive of what I do as it keeps me out of mischief.)

Anyway I’m starting to drift a bit, so in my last post back in 23 I think I stated that there were estimated in 2022 to be something like 45 Billion photo capture devices on the planet, enough for 5.5 units per person that inhabits this Ball floating in space, a phenomenal number. And now there are probably even more.

The traditional camera is being ditched though and as you can see in this graph supplied by Statista It is a seriously declining part of the consumer market.

The number of digital single-lens reflex (DSLR) camera shipments worldwide has been on a downhill ride since 2012. In 2023, a total of around 1.18 million DSLR cameras were shipped by *CIPA companies all over the world. Despite the decline in shipments, the average price of digital cameras per unit has continued to remain stable.

In eleven years the annual sales of a DSLR has dropped by almost 16 million units in 2012 to a paltry 1.18 million in 2023, as I’ve stated the sales of mobile devices have probably quadrupled and risen in the opposite direction.

The question is, are traditional cameras going to be more of an antiquity in the near future or will there always be a demand? There are so many out there that I can’t see them commanding any good price through rarity as there are just so many out there.

I learnt my trade in photography back in the late 70s early 80s. Back then we did everything by hand from mixing the chemicals, manually printing using enlargers and various types of papers, dryers and drums. Dodging and shading, manually touching up any defects as work was produced. We even made dupe trans, did letrasetting and made the boss man tea. A computer does it all now….apart from the tea but I bet that’s on the horizon.

The chemicals we mixed were in 100 litre batches and were pure poison. E6 Colour developer contained Hydroquinone, and the final bath (Stabiliser) all this chemical was pure formaldehyde, we never had masks or gloves back then and after mixing a batch of these chemicals you were out in the yard for a good half hour coughing your guts up. There were many other chemicals involving ammonia and powdered citric acid and these were just a few of what we used. If you could only imaging the shear hell we went through for you to get your photographs.

Probably why I have such bad Bronchitis and Asthma nearly 45 years on.

What I’m saying is the digital world of today is immense progression and removes all that danger away from the business. It’s killed the business as much as any other big business out there. But it’s probably not as much fun or as much pleasure as doing the whole process by hand using traditional skills. Heck I bet that will kick start a conversation between the traditionalists and modernists.

Whatever way we look at things, time moves on, progression is always going to occur and we must (Even though we don’t always want to) adapt to change. And it’s going to change for everyone big time in the next decade or so.

Even though it’s like saying goodbye for a final time to a dear old friend. I enjoyed my role I played in it.

The section “digital cameras” includes the following producers: Olympus, Casio, Canon, Kodak, Sanyo Electric, Sigma, Seiko Epson, Sony, Tomy, Nikon, Panasonic, Fujifilm, Hoya, Ricoh.

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
And then there were 12

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.

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
90% off. What have I brought?

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.
