Hehe, ok, I'll be 'that guy'...
I sold my GR again after only 4 weeks...
I agree with everything Bill and Garry said (except maybe that I prefer Olympus' implementation of the digital level).
I loved it's "dowdy, workmanlike" ways... (In that it's only 'bested' by the utilitarian "design" of the original Sigma DPs
Which I loved too...)
But... since I intended the GR as my everyday, take-everywhere camera I was disappointed with its shortcomings in regards to close-up/macro shots.
Especially in a nature-rich place like Oregon that was a bit of a disappointment. (Now that I live in a "big city" again, that issue might not be as big anymore)
Then... I couldn't get the colours to my liking. The DNGs didn't play nice in Capture One. The included Silkypix converter was not great. And the jpgs sometimes had a cyan/green cast to them. All in all, I couldn't get the colours similar enough to my m43 & 43 cameras.
(Which brings me to another point: I already had a EPM2 with 14mm lens (and 20mm and 45mm)... Neither of these lenses are quite as sharp as the GR (well maybe the 20mm is), but they're not terrible either. And sensor-wise I couldn't see a huge difference between the 6 year old APS-C sensor vs the 4 year old m43 sensor...
Oh, and one last bit: I didn't like the chemical smell of the grip rubber which made my hands smell - even after 3 weeks of use
So there!
