We know that some people have a lot of gear. How much cameras passes the 5 rolls a year threshold? For me I go thru some months of inactivity then I have a period of time when I shoot off some rolls esp with b/w because I don't want the chemistry to go off. This is the film forum so mine are the Nikon Fm2n, F100 and a RB67 and Hassie 500CM. All 4 meets that threshold eventually.
