These are my results from the first test of a homemade lens that i attached to a pentax spotmatic . Its fixed focus from about 6ft to infinity . There is no aperture changing system fitted at the moment hence the extreme softness , judging by the meter readings I'm getting i would guess its about f4 .in retrospect perhaps i should have tested it with fresh film to start with as the tri _x i used is very expired
