The Fuji 303 is a fairly small camera.
If you want something smaller, you will only find point-and-shoot cameras.
You can continue with the same approximate size, and get a camera with all the manual over-ride controls.
Such as the Canon A95.
So where do your interests lie, point-and-shoot or a camera for the more advanced photographer?
I currently have a Fuji A303 camera and have been fairly pleased with the results from pictures I have taken. I now want to upgrade to a better camera and there are a few different options I would like to take advantage of from other cameras. I am looking for a compact (smaller than my current Fuji), a camera that doesn't take long to refocus for another picture to be taken, picture quality etc. I am looking to spend no more than $400. Any help is appreciated.
