Re: [Digital BW] OT - Old optics on modern digital cameras (for example, Canon FD on Sony a7)

2015-09-30 by Ernst Dinkla

Paul,

A friend is converting my Canon FD 24mm 2.8 and 135mm 2.5 to EF mount + chip, the lenses are at least 10 years not used. More in view of an A7R II purchase + the EF to FE adapter than on the Canon 5D II that is my current camera. I already have an FD 55mm 1.2 with an EF mount. There are some EF lenses that I would use too and then I can go with one adapter for all. Wishful thinking probably but the chipped mount may even inform the camera which lens is mounted and maybe the IS gets the right focal length set that way. Depends on the adapter firmware upgrades whether that will ever happen.

Curious about the de-centering remedy.

Uncompressed RAW is announced for the Sony models.

My workflow to make a good B&W print starts with a good digital RGB image. In a Lula B&W thread someone asked about the best camera for B&W that was reasonably priced. My recommendation was to buy a used Sony a7r (36 mp full frame). I thought I'd put a similar follow-up message here since the topic involves limited resources (out of production equipment) that I'd rather see this group be able to take advantage of.


So, assuming a good digital body like the Sony a7r, the next step toward getting a very high quality image is obviously a very good lens.


I have the very good Sony-Zeiss FE 35mm f/2.8. It's the lens I use more than any other. This modern optic, with multiple aspherical elements, costs $800 at B&H. As good as the "Zony" 35 is, I like manual focus for landscape shooting. Among other things, it's easier and faster to do a dual-focus image capture when there is a focus stop.


My current MF solution is the 30 year old Canon FD 35mm. The Zony is certainly better from f/2.8 to 5.6, but at f/8 I'll let you decide which is better, the $800 or $80 lens.


See the comparison of the center and worst corner of the series at

(This was with the new Sony, but the old one is virtually equal for these purposes.)


The lens itself is just part of the story, of course. (I made a custom lens profile for the Canon and also was able to offset most of the focus errors due to slight de-centering on the Canon -- topics I'll probably document in a PDF at some point.) However, the point is, there are some old classics out there that are amazing bargains.


FWIW
