I finally got around to putting some more photos into the SX50/SX60 folder.....new ones start with the Carolina Wren (after the Little Blue Heron.) All are SOOC, unless otherwise specified in the "details," under the number of the photo.

The day I took these I stayed mostly in the optical zoom range, and attempted to keep the SX60 close to the SX50's max of 50x. It's a little tricky trying to guess where that is but I tried, since a couple of people wanted to know if doing so would result in better IQ from the SX60. I don't believe it did, but people considering the camera will have to judge for themselves, and decide whether the improved features outweigh any differences in image quality. Not everyone uses a camera the way I do, and those who mostly shoot at more modest focus lengths and distances might really like this camera.
Initially, I thought a slightly lower IQ from the SX60 wouldn't bother me, since I take photos mostly to id birds and for record-keeping. Once I realized the issue seems to be with image stabilization though, I changed my mind, since I do a lot of shooting at long distances and that's where this particular problem will have the most impact. Heck, who wants a "superzoom" that can't "superzoom"....!!! ?
Joking aside, I tried to give the SX60 the advantage, almost always shooting with it first, and taking twice as many shots with it as I did with the SX50. I didn't include any series where the subject moved to very different light between camera switches, and I didn't include any small, energetic birds because none stayed still long enough for me to get multiple shots with the SX60 and still catch them with the SX50. However, I know the SX50's capabilities well, and was able to shoot enough small birds with the SX60 to decide that for me at least, there is no comparison; small birds, long distances and camera shake make for lots of UFOs.
