1:1 format
I love to use different formats, rather than just the usual 3:2 ...in the same way as my Panasonic LX3 is almost permanently switched to 16:9, the Ricoh CX1 is already getting plenty of use in 1:1 format, as it does suit certain compositions really well.
Most medium-format photographers will know how useful that can be (as well as a hindrance in some cases, for them) ...CX1 gives you the choice.
