FD Lens to EOS Body

[Mark Avenell]

Ive just got a sigma 400mm fd lens for canon. What adapter do I need to fix it to my Canon 10D? Hope you can help me.

All the best

There is an FD-EOS converter that can occasionally be found on Ebay. But beware, most of them are not for longer lenses such as the 400mm. They must have optics in the converter to allow them to focus to infinity. Also there is no automatic control of the aperture, you must manually shift it after metering. So you will need a hand-held meter to get exposures. And of course there is no autofocus. It is a pain to work with - you are better off dumping the Sigma and saving up for a 100-400 EOS lens.

No, not really.. The light meter will work fine, and in M (or Av) it will work fine, no need for a hand-held meter.. Just dial in wanted aperture and change the shutter for an correct exposure..

But i agree.. you really should get a lens that fits right on.

Yes the light meter in camera works but..... when you use the adapter it disables the camera's aperture reading because it doesn't "find" an EOS lens. Therefore all you have on the display is a shutter speed which is not very helpful. Otherwise you will have to take the reading you get for the shutter speed, assume the max aperture at 2.8 or whatever the lens is rated at and calculate an adjusted shutter/aperture combo. Not very fun so its easier to use a handheld meter.

Hmmm i thought that the FD-lenses acually stops down the lens when changing the aperture (it was some time since i used the FD-system). Therefore you just stop down to desired aperture and the camera will take care of the shutter-speed. I might be wrong here, and if i am im sorry anfd rest my case ;)

It looks like SRB in the UK sell them :-

I got an FD-EOS adapter through Adorama. I use it with an old Canon 50mm f1.4 and 500 f8 or f11 mirror lense on 10D and Elan bodies. It mates nicely. Pixs are just OK. I have a sentimental attachment to these two (my first) lenses. Can't part with them. Soon to be for display/conversation pieces only, as they have little monetary value.

Yes, they will. But you have to move the aperture control lever on the lens mount to the locked position, and the aperture control ring on the lens barrel out of the A (automatic) position so that the aperture can be manually set.

The 10D (and most other EOS cameras as far as I know--my Elan II certainly does) will meter actual light. So, if you stop down the lens manually in Av mode, the camera will select the proper shutter speed based on the selected metering method by measuring the actual light. It will even to E-TTL flash control, but you have to use the Av or Manual setting. The F-stop shown in the finder will be "00", which means it is measuring what it actually sees, not what it assumes will be the case when the lens is stopped down.

I also have an FD lens to EF-mount camera converter, and it has an optical element that reduces the resolution of the lens about as much as a cheap teleconverter. It's been a while since I used it, but I think it stops the FD lens down automatically. The optical element is needed because the back-focus of the FD lenses is too short to be adapted in front of the EF lens mount, as others have mentioned. The one I have is not of particularly high quality, and I think that is normally the case for these.

I too have some older FD lenses and called my Canon "expert" rep I always use and he told me the FD lenses with the adapter would just not do the 10D justice and I believe him. I opted for cheaper Sigma lenses for the Macro and wide angle because I cannot afford the "L" series until I pay off the camera and other accessories. I would definitely go for the EOS lenses and you won't be dissappointed.
