Anyone else using the Canon EF 40mm pancake? Seems like the 50/1,4 is the most popular gal' in the class for street photos.
I've been using my 40mm pancake on my EOS 3 more and more lately. It's the eye-control that does it for me, more than once i've been lining up a shot, see something move in the background, straight away it's refocused on that and i've got a much better shot. Mostly with B+W film, last roll was Ilford 125, sometimes it's T-Max 100 or 400 or BW400CN.
My other new favourite toy is a (Cosina) Voigtlander Bessa L. TTL Light meter, fully manual, L39 screw-mount. No viewfinder at all, just guess and shoot, perfect for 'shooting from the hip' (also a lot more subtle that way). I've only amassed 1 lens so far (besides SLR lenses I can use via adapter), is the 21mm f/4.0 Color Skopar. Absolutely amazing lens, second only to the Zeiss ZM Biogon, ZE Distagon, or Leica Super Angulon, except the Skopar cost me $200, they're $500 new, compare that to the Zeiss or Leicas. Came with a viewfinder too.
It's also a great tiny/featherweight hiking/landscape camera with a roll of Velvia 50.
(I also almost got a Bessa R3A and Ultron 40/1.7, but the bidding went too high for me. One day i'll get the R3A and put on a 90 or 135mm, for candid street portraits).
