You got the RX10? What do you think of it? You're the first person I "know" to have gotten it...
Funny story on that one - I wasn't actually 'looking' to get one, I just happened to roll by my local Sony store which was closing, and they were having sales - the sales were 50-90% off everything except cameras/lenses (as they said it, anything in boxes counted, anything under the counters was not included). I picked up some memory cards, spare batteries, LCD protectors, etc for cheap. While there, I noticed a single camera box sitting on the stool behind the counter - RX10. I asked about it, half joking, saying it was 'in a box' and not 'under the counter'...surprisingly after discussing it with some other EEs, they decided it could be included in the sale - it was literally the ONLY camera or lens sold at the sale price of 50% off. For 50% off, I couldn't pass it up!
I bought it, and within a day, I was talking with my stepfather and told him about it, and he began begging for the camera to replace his NEX3 (my old NEX3) - he travels often, and a single, fixed lens camera with a better zoom range and fast lens suited his needs well...so I technically sold it to him that next day for the price I paid - only if he agreed to let me play with it a little bit - he won't need it for his next trip until late April, so I am holding onto it a few weeks to experiment.
It's a great cam - solidly built, and the lens is truly gorgeous - super sharp and crisp wide open and down, at every focal range. Very well matched to the sensor in my opinion. I can see why the RX100 got raves - it's quite an accomplished little sensor, that 1" one...not up to the high-ISO capabilities of the APS-C, but in good light, it's excellent and still usable well beyond most P&S cameras.
One thing I really love is that it is like practice and preparation for my upcoming A6000 - it will use the same menu, and many of the same controls and features (lock-on AF, quick navi setup, all menus, etc) - by the time I get the A6000, it will already be familiar!
I put up two threads of wetlands shots with the RX10 over in the DP Review Sony Cybershot forum - feel free to take a look so I don't hijack this thread any more.
I'm just spit balling here, but I would think that aligning handheld HDR is more difficult in cameras with slower burst shooting, such as entry level dSLRs from most brands. Mirrorless cameras and Sony dSLTs can typically shoot bursts much faster (2-4 times faster than entry level dSLRs), which may make it easier to align the images for HDR.
Or maybe that has absolutely nothing to do with it, lol.
I'd venture that's part of it for sure. The fast burst helps keep the alignment differences small - though all of Sony's alignment functions in camera seem to be a step ahead of most - HDR, multiframe, and pano stitching are all done with high degree of accuracy and few errors.
