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.




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.
