You are excused I'm a fan of your Canon FD to EF products.I was wondering, since we all know Nikon lenses can be mounted on Canon bodies but not viceversa, is it not smarter to buy manual-focus-only lenses always in Nikon mount and buy an adapter?As long as its a totally manual lens, you only have to deal with the somewhat klutzy adapters. If I were buying a new lens and it was available in Canon mount, thats the way to go.
That would minimize the inconveniences of side-grading, and would make expensive lenses such as Zeiss, Voigtländer and Schneider-Kreuznach a very safe investment.
Is there any disadvantage I'm neglecting? Any problem with aperture control?
However, in terms of being able to resell a manual lens, having one that could be adapted fit Most DSLR bodies might have the most value.
Not only can a Nikon F lens be adapted to Canon, but also to Sony/Minolta, and a few others. That increases the possible number of users who might want to buy it. Just watch out, many of those old Nikon lenses have odd protrusions or other gotchas.
Of course, buying vintage medium Format lenses with their very long flange distance would allow them to be adapted to almost any DSLR. The old Zeiss Hasselblad Distagon T* lenses are fairly good and low priced for a Zeiss lens. I've adapted one, and I love the smooooth manual focus.
Not all adapters are Klutzy (good term!), just most. Of course I'm biased, I make adapters (that are 5X more expensive than the norm).
I did not realize that you made Nikon to other Body adapters.
