ALLWAYS with me is Olympus MjuII(I am not professional photographer but MjuII(35mm, f2, spot metering) is allways in my pocket, where ever I go), from time to time Konica Auto S2(in any case I have with me, often simply under jacket or in hands), and my main camera is Canon EOS3 with 28-135mm IS, and 50mm, in Canon's bag. Very rearly I use 75-300 lens(I didn't use it for more than year, it is "bad" lens), and 420EX flash, but only when I know I MUST to use flash...

And I have Yashica MAT 124 with teleconverter 2x in "studio"...

Mainly for Olympus or Konica: colour is Fuji Superia 100 or 400(more times than 100) and for b/w Kodak T400CN.

For Canon both mentioned(but T400CN in Canon is set at 320, not 400), EFKE(from 25-400), slide(Velvia, Provia100F or whatever I can find) very rearly(in my country here is big problem with slide buying and processing).

For Yashica, Ilford Delta 100 and HP5.
