Mike Johnson (TOP) recommends the GRDV
In one of his latest blogs, the Mr Everything of TOP wrote the following exchange:
Chris Nicholls: "For me at the moment it's the M9 with 35mm ASPH Summicron. It's hard for me to imagine another camera that might suit me better, but I wouldn't mind a good pocket-size camera. Any recommendations?"
Mike replies: Always. The two truly pocketable cameras I seem to hear the most good things about are the Sony RX100 and the Ricoh GRD IV, with the Panasonic LX7—which has a Leica lens—bringing home the bronze. Here's my brief experience with the Sony.
Note that in Amazon's unintentionally funny product description of the GRD IV, "1X Optical Zoom" means it's a fixed, single-focal-length lens.
