I'm not switching out of my RZ/Aptus that's for sure...
... but along with the new Nikons, Olympus has a keen looking digital OM... Sigma just dropped the SD1 price to $2299... Sigma also just announced DP1 and DP2 models with the SD1 sensor... new canon lenses. Fulji X1 Pro. Maybe new Leica and Canon models.
Simply a ton of compelling new options for the photographer at the 35mm level. Lenses, bodies, accesories, new tech... wow. On top of that, we have the great Nex cameras and a growing arsenal of m4/3 options.
It seems like, for the artist, the toolbox is becoming filled with an unlimited palette of high quality "colors" and I, for one, find it really exciting. As an MF shooter I've struggled to find a compact camera that fit my personality... the new OM or Sigma models might finally do it for me.
