I am Planning to purchase the a cybershot camera can any one suggest which one would be a better choice as between DSC T99g or H55 as both are priced equally with major diff at 1) Zoom ie 10x Vs 4x 2) non touch screen Vs Touch screen 3) And about HD Recording in camera.
It is common for manufacturer to use the same sensor in a compact and an ultra-slim camera as this is the case. That is why the specifications seem similar but in terms of features these are quite different, mostly in favor of the larger H55:
BTW, you can see the any number of cameras side by side by searching for the specifications you are looking for using the camera finder at neocamera.com.
To see those two cameras, simply follow this link.
