[/QUOTE]To answer the other question, I have the 80mm. I seem to be doing an abundant amount of portraits and will be doing some table tob stuff... Love how close you can get with these TLR's....[/QUOTE]

Your 80mm will focus to 35.4 cm from the film plane, the 105 58.4, and the 135 90.2mm. The 80mm is usually considered as equivalent to a 50 mm in 35mm work and will certainly produce a typical portrait if properly aligned to the subject. The 135mm lens will yield a portrait image with little perspective variations, thatís all
