The Sony TX1 is the only one of the group that does better in high ISO shots, which are needed for low light situations like concerts. It wont give you perfect shots, but it'll do better than any of the other ones, including the other Sony. It utilizes the new Sony backlit sensors that don't produce as much noise in high ISOs.
I always have issues with zooming in, or else the fact that the pictures are always blurry due to the moving of the performers. I also like to have a big screen on the back to view. I have looked at the new touch screens as well, I have an iphone and really like that technology. These are the cameras I'm looking at, does anyone have any suggestions on which of these would be best for concert pictures, or if I should look at another completely different model? I do also take pictures of my dog and I like to take flower pictures, so I need zooming for that as well. But my main concern is concerts. Here is my list:
Olympus Stylus 7010
Olympus Tough 6000 or 8000
Sony Cybershot TX1 or T90
Nikon Coolpix S70
Thanks for any help!
