Shot 2 rolls of film at a first communion & family party last weekend. Was using a 35-70 zoom. Idle curiosity (and boredom during the sermon) led me to keep, more or less, track of the focal length I was tending to use. (actually wondering if I could justify a bigger, faster, sexier zoom).
Except for obvious attempts to catch things too far away, or squeeze one more relative into the frame with my back to the fence, I was hovering around 45-55 mm. Emptied the OM-1 and switched to the Fed-2 with it's collapseable 50mm.
Almost as if to confirm this not particularly rigorous data, I did note that I felt no real desire to use the J-12. Back yard party and mandatory group photos. Different story at indoor parties during the winter; 24 & 28mm, 35mm on the RFs (wishing for a 28).
50mm has always been my first choice for so called "street" phtotgraphy of people. Street implying out pf doors with room to step up or slide back. I carry around a Minox with it's 'normal' lens (the only thing normal about Minox...) and never miss having the typical p&s zoom, even indoors. My wife forgets that her camera even has a zoom ("too many buttons").
---I seem to be waxing absurdly verbose, but it took this long for my scanner to get to frame number 12. 😱
