Looking to put together an appropriate kit for a IIIf. The idea behind this is a compact, fully mechanical kit with no more than 3 lenses for "walking around" photography. Would like one lens with fair low light capability, probably on the short end of the scale. Nothing in the kit should be over 50mm, as I like it up close and personal.... Oh yeah... I don't want to mortgage the house and sell my digital equipment to fund this newest obsession! Recommendations? Thanks!
