I took these today with my canon 400d and a manual lens canon 50mm 1:18. I have remarked before how i thought this was a soft lens but these pictures puzzle me. all taken with the manual setting on the camera, aperture ring at f8 as it was not sunny, looked to be focussed properly in the viewfinder but this is how they came out. i used a sears 300mm lens in a canon a1 in the film section and had far better results. This lens is still soft on the a1 but not like these pics. Anyone got a theory on this?

Well I don't know much about DSLRs, but could you set the lens at known distances to eliminate focussing errors and view the results.
I have the FD 50mm f1.8, FDn 50mm f1.8 and FDn 50mm f1.4 and they are all very good at f4 to f11 (my usually shots)......dunno about WO.

The bokeh looks almost mirror-lens like, very strange. It also looks as if you're shooting wide open. 
Sorry I can't offer a solution.

Just thought:- how are you using an old Canon FD lens on a Canon DSLR as they changed the mount and will only work with an adapter, the VG Canon one is rare and expensive, but if you bought a cheap adapter with glass (to get to infinity) the quality can be poor.

Well to answer the question  I have been using an adaptor i got as part of a package i bought . I do have a lot of trouble with infinity, but that is also the case with the m42 adaptor i have. Saying that, the m42 is very good on close stuff whereas this canon doesn't seem to be. But, have a look at the pic below, taken with same camera and adaptor but with a 300mm sears lens (you would think not as good as a canon), infinity or close to. I took distance shots with the fd 50 and they were "bloom" infested as well.
sears 300mm

Well, then this is a perfect answer to the question "how bad these glass adapters really are?". M42->EOS adapter is glassless, it won't affect the picture quality at all. Chinese FD->EOS adapter has low quality glass, which gives you what you get. It really is a waste to use good quality FD glass with these adapters (unless you like that look of course ).

I am always amazed by how perceptive you are Fermy  absolutely correct in regards to the adaptors, the m42 has no glass the fd does. The only flaw i see is why is the sears picture so much clearer? they are both (the 50 and 300) canon mounts?

Lol. I thought Sears was m42 mount.
Anyway, there is no reason why different lenses should show similar IQ degradation in the presence of the adapter. One possible explanation is that the phenomenon in FD picture is caused by the light bouncing between the adapter and the lens rear element. Since 50mm FD has a rear element much closer to the adapter than 300mm Sears, there would be a greater IQ loss. All wild speculation though.

definitely fd on the sears 300, though i have a sears 135mm on the way that may be m42, not too sure. I didn't think you were a man given to wild speculation ! i may have to try to get a better adaptor.....

As the colonials say "Its a theory" . I am gonna try out a few more lenses on it, and mess about with camera settings.
As regards excalibur, i have good results on my canon a1 with the lens, so it must be somthing to do with the digital camera or adaptor or a setting. A process of elimination i guess. Watch this space, but do other things as well

I have seen good results from other users of an adapter with glass, so I think you need some luck in getting a good one. |
