A newbie question, in a way ... About a new to me c1952 SUMMICRON LTM 50 2.0 Collapsible.
I used it this past weekend on a IIIf with some FP4 and the lens was sharp although low in contrast I found (but predicted when I read up about this lens). I chose not to use any filters or shade because I wanted to see a "raw" result. As it happens, although lowish in contrast under my normal development, there is an annoying internal barrel type circular flare at the bottom right hand of the negs, but only when the lightest part of the sky was at my left shoulder. Looking into the lens, I see there is a thin chrome ring right before the aperture leaves although the rest of the lens internal is black. Seems to be a strange decision to have this reflective piece.
Anyway, I'm thinking that a lenshood is a must have for this lens, for flare and for contrast, and although it is the "thorium" glass I'm thinking a Yellow filter too, more or less as a fixture for my Ilford range of BW.
I don't want the older style collapsible shade, so I guess I'll go for a slightly newer clip on?
Would appreciate comments about the lens in general, the flare issue, and especially a recommendation for the lenshood.
