The thing with vintage glass is that you will hardly find 2 lenses in the exact same condition.
Nail on head.
Remember, they actually WERE still camera lenses about 20-30 years ago, and they used them to capture all sizes back then!
Sure, but the lenses were also designed for a different capture medium then - film. I'm not an expert on the fabrication of digital sensors, but I would guess - from experience using the exact SAME Nikon lenses on an F2 and then later adapted to fit the 7D - that there is a difference in how the lens and capture medium work together to create image sharpness. I used my Nikon 50mm 1.8 (sold it), 50mm 1.4, and 28mm 2.8 on my old F2 back when I was shooting black and white film about a year and a half ago. The sharpness of the 8x10 prints was enough to cut you just by looking at them. Using the same lenses on my 7D for stills (glassless adapter, of course), there is a slight drop in sharpness. Granted, it is SLIGHT. A simple Unsharp Mask in Photoshop can fix it, but there is definitely a difference. If I have time, I will post some photos. I've mainly noticed some issues with resolving fine detail and in edge-to-edge focus, but I think you might be right - this could just be the "character" of the lens, as these are older than me.
Of course, my 85mm AF 1.8D stopped down to F4 is brilliantly sharp. It is a great lens for closeups if used right, and if it weren't for its somewhat awkward focal length when compared to, say, a 35mm, I would be using it far more often.
