Excerpt: The Power Shot A590 is an extremely useful camera for beginning users and is moderately priced for a starter camera. I don't have much anything nice to say about it outside of this. The reason is, because it drains batteries like nother camera that I have seen before. I can only get off about 40 to 50 shots off before the camera shuts down and leaves cameraless.
Cons: Image quality was low, serious lag time between pictures, battery life under 100 pictures! I've tried to make this camera work for me for the past year, and I have never really liked it. It wasn't worth the money spent.
Pros: Small size, good picture quality, good color and clarity in daylight, uses AA batteries, SDHC memory card, a conventional cord and USB 2.0 interface, viewfinder, manual controls, AF assist lamp. Remembers the choices after the camera was turned off.
Cons: The flash does not cover the entire field. The center was overexposed while the edges were dark. Flash also takes too long to recharge. The pictures had too much contrast and the shadows were too dark, not balanced overall.
Pros: Quality of pictures is average. Do not see why is so highly rated especially when it needs to be recalled due to such a battery problem.
Cons: Canon PowerShot A590 IS has a serious battery problem. After only 6 pictures it shows that battery is empty and it wil not work. This camera is a joke and I cannot believe how highly is rated. Please do not buy this product.
