There's an awful lot of fine glass out there which is as old or older than I am, which also mounts to my EOS camera with the use of inexpensive adapters. Many of these lenses are still considered to be some of the finest examples of camera optics ever to be, even though they occasionally predate the second world war or earlier.
Yes, there are many arguments pro and con, yet it remains that many film 'purists'
have been giving these lenses new life by mounting them on their sparkling-new
digital cameras, and they are mostly raving about how much they love the lenses
from their 'lost eras' when used with modern digitals.
Carl Zeiss, Helios, Asahi/Takumar, Tamron, Soligor, Hanimar, Leica, Chinon, Olympus/Zuiko, Voightlander, Yashica, Jupiter -- They're all good lenses, and more.
I am confident that we have many manual-focus users right here on this same forum,
so why not open the forum to such endeavors? There are dedicated resources for this,
I know, but why shut this aspect out of the digital age? I hope to acquire one or two
SMC Takumar lenses, or a CZJ lens in my time. Maybe a Russian mirror lens, or a
M42-mount cinematic projector lens. Lots of possibilities, actually.
But what's keeping this aspect of lenses out of the fold?
