Right, I am now a fully paid up member of the club. Opening those files in LR4 was impressive.
Back at home, playing with the camera and all I can say is colour me impressed. The Fn button is key - I've assigned mine already, it really feels natural. ISO first, DRO/HDR second, metering third.. and so on. The left button is AF area, the control ring is exposure compensation. That's pretty much everything I do on my SLR plus more in two or less button presses.
Specifically, the HDR mode is awesome - and Sony's in-cam alignment is still the one to beat. The Canon HDR of the S100 etc needs a tripod - I don't know about you guys, but if I had to take a tripod I'd be carrying an SLR or manually bracketing. Having said that, I do have a credit-card sized tripod clamp which might come in handy for long exposures... As for the Nikon's HDR... well, they're behind on that front. The V1 could have, but didn't. The 5100's was poor, and proper bracketing on the higher models requires a proper tripod.. :]
The watercolour and illustrator modes are great fun, I can see more than a few being printed out!
Oh, and the camera feels really well made - a proper little brick, although it's still light and compact. I like the minimalist looks, too - I've seen a few leatherette skins on posts around and for once they add to the look and feel of the camera. A bargain at £429 - if this was a Leica it'd be £899...
Very pleased. Not perfect - closer focus, a faster lens at the long end and a stepped control ring would be plusses for me - but when I sit it next to the D3100 and 18-70 combo [in itself a small SLR setup] it looks tiny, tiny, tiny!
