Don't know about the Canon, but my Nikon D5100 has a +/- Exposure value setting on the settings screen. Or, how about using a CPL or ND filter?

Only reason (assuming the lens and the setup are in propper working order) has to be improper metering. You might want to to try total manual and meter of an 18% neutral grey card. Lacking the card meter off your palm. Use thes settings and see if don't over expose. If this doesn't work it has to be the set up.

Based on what you said and how I interpreted it, I would lower the ISO.
Go out on a sunny day. In manual, use these settings:

ISO to 100
Fstop to 16
Shutter to 125

See how that turns out. May not be perfect, but if it is close maybe it is working ok.

If cloudy, there are other f stops to use as a guide. I just don't remember them.
Google, "Sunny 16" and the results should lead you to the other guidelines for shade, heavy shade and light shade.

Also, look thru the lens while adjusting the f stop to see if it is changing in the lens.

That's about all I got....
Let us know what you find!
Pat

Edit: I remembered on my FD lens, there is a "lock" at the end of the lens. If it is set one way, the f stop cannot be changed. Move it to the other position and the f stop should adjust. Again, look thru the lens only in your hand while changing the s stop.

Look to ensure the manual fstop ring is actually changing the aperture. I once was looking at an FD lens for my old canons and the aperture didn't change no matter what I did to it.

JP, I don't know what problem you're having. I used to have the FD 55 1.2, and was just shooting with one of my FD teles this morning, and I've never had a problem. I've always used the EdMika glassless adaptor.
The lens will be full manual. The aperture ring will also be manual. Regardless of your settings, all exposure needs to be controlled manually. In other words, you need to stop it down till the meter in the camera says its correct. If the camera meter shows proper exposure, it is.
It sounds like you are saying that it says it's good, but it's not?
Your EOS camera does not have the ability to stop down the lens or control it in any way, you do that manually.
Or am I completely misunderstanding you? ;-)

I have this same problem on two old FD lenses; no matter how you set, manual or auto, the aperture does not close so every shot not requiring the lens to be wide open is overexposed. Best thing to try is to set the Av to F16 and look into the lens as you press the shutter, if you don't see the diaphram close, you have found the problem. Another way is to look through the viewfinder and try the aperture preview, if the view does not darken, your lens is not stopping down. I have not bothered to have mine fixed, not worth the expense!

At what aperture are you trying to use this lens in bright sun?


what are the settings you have set when trying to use it and failing?

An EOS body, does NOT have the ability to stop down the lens, only an FD body can do that.
If the camera does not recognize the lens at all, it will either give you an error message, or you will see TTL, but the camera won't fire.
The metering system is entirely in the body, and has nothing to do with the lens. The body should meter the light, but you have to stop it down manually at the lens with the f-stop ring. I'll check my 50 1.4 later tonight or tomorrow and see what it does on my body, as I've never had in on it before.
Does this make any sense? ;-)

In my case I was using the FD lenses on an A1 body. Two lenses, a 35mm and 200mm work fine, but my 50 and 85mm dont stop down, wasted a couple rolls of Fuji finding that out! Definitely a lens issue. They are 40 years old!

Read the thread below and follow the links. The Ed Mika approach should get everything working. I have an FL 55mm F1.2, and other modified FD lenses, but they do need modification to mount without a cheap glass-based adapter that reduces IQ, and also to provide the aperture control that is needed for proper exposures.

Good luck

Are you sure your 50 and 85 are FD and not FL?

Thank you guys for the replys. Now I tested out what everyone suggested and came out trumps.the iso n shutter speed is controlled via the camera.the f stop is via the lense.but the light meter is out I need to over expose the shot by two marks to get satisfactory light.plus if I go under fstop 2.8 my subject will ghost abit like a soft focus lense.otherwise I'm happy with the result for as u guys said a 40 yr old fd lense n a fit dioxide pro adaptor.i may as it was a test find a 60 mm fd lense

I just bought a 400mm f4.5 fd to go with the rest of my 0ld lenses. mine are mounted on sony alpha cameras. I set the camera to manual.
1 set aperture on the lens.
2 set the exposure compensation dial to zero.
3 take a shot, see if you are satisfied.
4 if not move to plus or minus side until you are.
