So I have mostly had experience with 60's and 70's SLR's. Occasionally through some lenses I see a little bit of a color fringe on subjects. I had never noticed till now, since it's pretty subtle.
I just got a much earlier (~1956) Zenit C and I initially assumed I must have gotten a bad I-50, since I see a ton of CA-like fringing, especially on bright lights like reflections of sunlight on plants or the bare LED bulbs in my kitchen. It does not go away at any aperture. I assumed CA, but then I looked through my Nikkor-S (my nicest lens) mounted on my Nikkormat and saw faint traces of the same fringe, causing me now to wonder if it's a property of ground glass focusing screens.
My question is, is the fringing I see on a ground glass SLR screen necessarily a product of the lens, or can it be a product of something about the screen or the viewfinder?
I haven't developed any film from this camera yet so I can't tell you what the lens looks like from the actual focal plane.
