My now-retired camera pusher, er, dealer, once asked me what I do with all these 'exotic compact cameras' that I bought from him. We're talking most of the major ones including the X100, X10, Ricoh GRD III, Sigma DP1, DP2, and on and on. My reply was that I shoot them, and they go into rotation after a while.
Film:
Contax T3 or Fuji Natura Black. They are my favourite film cameras, ahead of the Leica M7, Zeiss Ikon ZM, Pentax ME, Olympus XA2, everything. At the end of the year, I'll be going overseas for a week and taking the Natura Black and a bunch of XTRA400. The T3 has ridiculously good image quality and a rendering which I love. The Fuji is more automated but has that fantastic 24mm f1.9 lens, unique in compact cameras.
Digital:
Most used are the Ricoh GR, Sigma DP1 original and Panasonic LX7. The GR has been on hiatus because of a shutter issue, and the DP1 only comes out for special occasions. The LX7 is my everyday snapshot and documentary camera. I love the 21mm 16:9 images, the sharpness and colour of the raw images, the snappy response, the very quiet shutter, the very reasonable video. The GR and DP1 have a depth and richness that small sensor cameras can't deliver, so they are the complementary cams to the LX7.
Tomorrow I'll be interstate with the LX7 and Sigma DP1. Fun times ahead!
