As for the claim that the lenses worked well on film, but suck on digital...I hear and understand your statement. Back when we were all shooting film we seldom subjected our images to microscopic examination (pixel peeking) and never had a chance to see them on a high resolution display. I have been doing a lot of scanning of my old slides to digital and have been amazed at just how crummy many of my most prized images are when scanned. Often enough the lens that is not so good on my dSLR sucked on film too. It is a little discouraging, but such is life sometimes.
You are right sir! After reading this paragraph, I couldn't resist and went digging for some of my old slides. After a few minutes hunt, I found several shot many years ago with the "suspect lenses". (Those slides were never scanned). So I called a friend who still has a good slide scanner, and asked him to digitize some of this slides. SURPRISE! They all show the same issues I am complaining about in digital photography. That means the lenses are performing almost identically, except for some PF at the edges on very contrasty situations....
You are right, I was used to see my slides either on a big screen (dark room) or with a loupe on the light table. Even though I was seeing the same issues (flare, distortions, PF, CA and such), I always blamed either the quality of the loupe or the quality of the projector lens. I even had some old slides mounted on glass frames back then, just to make sure they were "flat" thinking my old projector's lens was not "flat field" and thus gave me blurry corners on projection.
And talking about watching slides on screen... How close to the screen? Always at least 10 to 12 feet away, 'cause I (we) were looking at the whole picture, not like now with high res monitors... that we've turned so picky, we forgot to see the whole picture and started looking for defects.
After this enlightenment, I could easily claim that I've recovered about half of my legacy lens arsenal... hurray!
