Happy New Year everyone!
I am just back from a ski trip with my grand kids during which I was able to get familiar with the a99 (I also had an a900 with me). Sorry, I won't post pictures as all the "subjects" are the grand kids... For the first couple of days I relied on the familiar a900, which I master quite well. My wife then told me she had forgotten to take her video camera so I got the a99 out of the box; I was greatly surprised and impressed by the results. It's easy to use, no nonsense and the results were terrific; I was filming at the end of the day, just at around sunset and slightly after with no direct sun light. So the next day I started shooting pictures. Not having ever used an a77, I was not accustomed to the complexity of this camera. I wasn't too comfortable, but I was getting interesting comments from the Nikocanon pros shooting pictures of the kids at the ski school (half a dozen pros are employed by a local photo shop in the village where I ski); all were positive ("great camera", "better equipped than we are!" etc...). I hadn't gotten such comments when the a900 first came out! I programmed the camera pretty much in the manner Gary Friedman recommends in his book on the a77 (it is strikingly similar). And, WOW... After about twenty minutes I felt very comfortable using the camera and all its buttons (P mode as well as 2 programmed settings, the first recommend by Gary in his book, the second to my liking on the slopes). That night I fine tuned the settings for the next day shoot as I didn't like the grain in pictures shoot at over ISO 800 (my initial settings had me automatically going to ISO 6000 in low light; too much grain when editing with Apple's Aperture). All this to say that I very quickly fell in love with the a99. So for New Year's eve party, I took the a99 and went wireless. And this is where the a900 really is better; over 50% of my shots had friends and family with their eyes half closed. Gary Friedman, in a short video posted in one of the Dynaxdigital threads shows how the driver flash on top an a99 goes off before main flash(s). The time is long enough for "models" to start blinking and the results are not good...
So my first take is: a99 for action shooting and a900 for wireless flash!
Also, I didn't get to use the GPS as Sony and Apple don't like each other; I understand there is software I can get to have the two work together, but haven't gone around to getting / exploring it. Any suggestions are welcome!
