FD 50mm lens causing T90 EEEE error!!??

kingbuzzie · Jul 19, 2015

So I have a canon FD 50mm (later model) that keeps triggering an EEEE error on my T90. I've tried other lens and tried firing it without lens on and the camera works fine. I've manually tested the fstops on the lens by pushing in the pins and twisting it... they all seem to work. What is causing this? Pretty frustrating.

If I remember correctly, EEEE is triggered when the lens is set in Auto and the operator tries to stop down the lens.

Yes this is one of the causes, make sure the lens is set on A.

I've set it A. I'm not touching the stop down. I ended up taking off the lens and reinstalling two three times and working the stop down switch over and over. Maybe it's sticky? Whatever the case, it is finally working again. I just now read that I can reset the error code with the batter check... a lot more convenient than taking the battery case off over and over. I must point out it's a different error than when you touch the stop down. It would fire once, advance then throw the code. I checked the lens on my A1 and it worked fine. The lens is practically mint.

Bump. This is perplexing and frustrating. I just shot a few with an old vivitar wide angle fd and worked fine. Shot several with the canon 50mm fd and "EEEE" nine times out of ten...

That's strange... Maybe the lens is not in mint condition.
I don't think it could be a camera problem, as it would happen with every lens (sticky shutter)

Haunted. Poltergeists. Thankfully FD lenses are cheap enough (for standard lenses) that you could procure another example if this one absolutely won't play ball with you. And yes, I'm a proud T90 owner, who more than once has had to clear EEE by slamming my camera on a carpeted floor...

The FD 50/1.8 is so cheap, that you can either try dissasembling the lens and checking it inside, or buying another one. It is possible that when setting the lens to "A", the corresponding pin at the back of the lens is not raising high enough, as it should. (It raises so the camera can detect that the lens is set to "A")

Or, you can also sell that amorphous-looking, colani-messed, plastic-skinned, glorified T90 mounstrosity and get a beautiful, sweet, good-looking, honest, straightforward and lovely Canon F-1, which will give you no "EEEEE" messages. Who needs multi-spot metering, anyways.

It sounds like the cams of the bayonet aren't working properly, have you tried to move them? Even my f1.4 is a little lousy and sometimes when I attach it to some bodies the diaphragm doesn't work.

Yep, a possibility.

To the OP: If the lens is a New FD, it's easy to dissasemble the mount. The mount's chrome bayonet mount is held by three or four screws around the lens. Take out those screws and the mount comes off easily. Then, carefully lift off the plastic assembly that holds the stop-down lever. You will then see all the mechanisms for the levers inside the lens. Some judgement and perhaps you'll see if it's full of dirt or anything that prevents the cams from moving correctly.

So I ended up sending the T90 back to KEH with just a couple of days left on the fairly generous warranty. They sent me another in pretty good outer shape, a bargain grade instead of the ugly. The KEH guy at first didn't sound too happy about me wanting to send the camera back, and explained that ugly grade are meant to break. Camera works great now, and it pretty nice to to look at as well. BUT... still has the gummy shutter problem. Is it fair grading a camera 70-79% condition with a obvious degraded part? They must have known, because I checked the shutter before firing it, and it was super clean. After one shot it was covered in gummy black, same spot as the old camera, same amount. So... I got a better body that would have cost more but same problem. Makes it hard to complain. I read somewhere about a guy sticking some paper down in there somewhere to clean out the rubber, but I'm scared to do it myself.

It's a fairly common issue that also plagues later EOS bodies made shortly after the T90

I must have got very lucky my T90 has none of these issues and I found it for next to nothing locally. I prefer it over the F-1 having started my photography on the d*****l EOS system, I love where the buttons fall and how it feels in my hand, it feels more solid and more full as I have large hands and the F-1 feels like a toy.

If he wants to remain in the 35mm domain there's always the mighty Kiev 15TTL:
