Not really had time to fully integrate the A55 into my shooting, due to weather and work. Yet to do any proper flash/portrait work, so bear with me. What I have discovered is how much fun the wee beastie is. From the first trial run in store, I've smiled when using it. I've quickly settled in with the EVF, finding it brighter than the old OVF from my A200/300 experience, but also more useful - I leave the histogram in play, so my exposures tend to be more spot on, all of the time. Another thing I rarely did, with the A2/300 was to venture over iso 400. Heck, stick a nought on the end, and I'll happily use the A55 there! Never been a great night shooter, and to be honest, not likely to unless the right shot was available, but as I finish at 8pm, with the camera with me, I've little choice at present. So, I was impressed with 1600, then I tried 3200 and 6400 - Sony poor at high iso? Not any more.
Ergonomics, now there's a bone of contention. It's too small, my fingers dig in, big lenses feel stupid...etc, etc. It's small, but feels good in my hand. For the first time since my Minolta 5d, my fingers don't squash against the lens. And with the Tamron 200-500mm, it felt well balanced too.
Video, not really tried, but the AF is swift and solid, but can jump too. More later, I hope.
So, first shots.
1) Iso 3200
2) Iso 1600, if I recall
3) Iso 6400 - handheld twilight
Finally 4) Sigma 105mm f2.8, auto HDR mode
