Okay, I took mine to the zoo and gave it a good, hard workout. Fast moving animals, flowers, extreme contrast, focus against glass, the works. It worked like a champ. Focus was reasonably fast (a squeak slower than my DLSRs but that's okay) and accurate. At the extreme zoom, a support would be useful, it does wobble a tiny bit. Not much but if you like needle sharp images, either up your ISO for a faster shutter speed or use a support. I like the fact that the camera is logically laid out, so you don't struggle to figure out settings. It's not heavy to hold and it fits into the hand comfortably.
It did fail to focus on a dragonfly on a flower, I think that was partially the camera and partially user error. I'm still learning all the features, so I didn't figure out how to zero in on a small insect fast enough to get the shot. It handled back lighting extremely well, even a xeriscape desert garden, with tall narrow cacti was correctly focused and exposed.
I really do like this camera. It will replace both my old SX-40 which was superb and my Fujifilm XE2 which will probably be sold.
