Timing
Since they're rarely reported on but very important to the picture-taking experience, I measure both cycle times and shutter delay times for all the cameras I review, using a test system I designed and built for the purpose. (Crystal-controlled, with a resolution of 0.001 second.) Here are the numbers I collected for the Fuji FinePix A303:

Power
The A303 uses two AA-type cells for its power source, and displays good to excellent battery life. (Provided that is, that you use high-capacity NiMH cells, coupled with a good charger. Read my NiMH Battery Shootout page for the latest on actual battery performance, or my review of the Maha C204F to see why it's my favorite charger.)

The table below shows the A303's power consumption in various modes, and approximate run times for each, based on a set of NiMH batteries with a (true, not advertised) 1700 mAh capacity:

Overall, good battery life for a fairly compact camera, particularly one running on only two AA cells. Still, heed my advice to purchase a couple of sets of high-capacity rechargeable NiMH AA cells, and a good-quality charger. (See my Battery Shootout page for performance details on the latest crop of NiMH batteries on the market, and read my review of the Maha C-204F to learn about my favorite charger.)

Storage Capacity
The A303 stores its photos on xD-Picture Cards, and is the first of the Fuji FinePix line to do so. A 16MB card comes with the camera, though I strongly recommend buying at least a 32MB card, preferably a 64MB one, to give yourself extra space for extended outings. The chart below shows how many images can be stored on the included 16MB card at each size/quality setting, and the approximate amount of image compression applied in each mode. (The more image compression that's applied, the smaller the image files, but the lower quality the photos will be.)
