The 200/2, 300/2.8, 400/2.8, 500/4.5 all have a calibration slot that can adjust the focusing element holder forward and backward. To get infinity you have to loosen the fastener on each side slightly, using gravity let the lens and holder module slide as far forwards as possible and retighten. In a few cases I have heard of with the 300 this didn't quite get to infinity and the issue was overcome with using a small circular file to extend the slots a tiny bit. It is also important with all the FD super telephoto lenses to have one of the UV filters installed, it affects the focal path and helps in reaching infinity. Check out EdMika.com for the videos on how to do this with the 400 2.8, the method is the same for all the above listed lenses. -Ed


Thanks for the tip on the UV filter- I wasn't aware of that.
Another post on the net noted infinity focus just with micro adjustment and no callibration - on other sites, you often note "FD 500mm 4.5L, unknown" so I wasn't sure if the process was the same.

Does anyone know if the 400mm f/4.5 SSC is able to be adjusted to focus past infinity to work with one of these adapters?

Unfortunately no, it doesn't quite reach infinity with just the focus element calibration. When I get my hands on another lens sample (I sold mine a while back) I will try the slight slot elongation shave to see if that would do it. -Ed

Sorry, came to this late - just to confirm, the 500 4.5L will focus past infinity with just the edmika adapter and the focus element adjustment. My copy did not quite reach infinity with just the adapter - from what I remember it would focus to about 400 yards - but after the adjustment, no problems. I did not have to file the end of the helicoil or anything like that.

I've just picked up one of the breech mount 500 4.5L lenses, and an Ed Mika adaptor. Interestingly, I can focus just past about 950 metres, but don't get the focus confirmation. For confirmation I get about 400 metres. I did some moon shots tonight which are not very sharp (comparable to a 70-200 f4L non-is when both sized the same. With a thicker glassless adaptor, I was only getting about 25m max focus distance.

I've not done the focus element adjustment yet, but it seems fairly straightforward. There is no rubber on this lens - the screws are under the tripod mount.

I have a EF 1.4x canon TC (version 1) which won't mount, as it doesn't fit through the opening in the end of the lens. It does work with the thicker adaptor tho, as the extra thickness means no overlap between the two.

I just bought an old fd 2x teleconverter.
With it I get past infinity focus on my 500mm f4.5 FD and an Ed Mika adaptor.
-I was limited to about 400 metres with focus confirmation before.
