I tried a P7100 for a while. I liked the flip up rear screen - I guess the 7000 had a fully articulating screen and so does this new 7700 so I guess the flip up screen wasn't anyone's favorite - other than mine! But I didn't like the camera. I think 28-200mm is just too large a range to do well in a camera like this. It seemed like whether I was using auto focus or zone focus, I had a REALLY hard time getting sharp shots out of this camera, even in really bright light. I'm sure there are some good parts of the range of the lens, but I tend to shoot wide and occasionally long but don't spend a lot of time in between, so I was probably missing the lens's sweet spot. Its a great form factor, size, good controls, pretty pleasurable in use. But I'm probably the least likely to pixel-peep among those of us on this forum, and I just couldn't get quality I liked out of it. Maybe I just got a dud???
Something like the form factor and size of the 7100 and these other models seem to me to be where a really good compact with an RX100 type sensor and a fast 24-90-ish lens could really work. Nearly m43 image quality in a single fairly compact camera easy enough to travel very light with. So I stay interested in these cameras, if only from a distance...
