Something to think about.
I don't see why the type of battery is a concern.
The Kodak should come with a battery and charger.
The battery should last over 5 years and the charger should last as long as the camera.
The lack of a viewfinder would be a concern for me too.
When you use flash, the camera must recharge the high voltage flash capacitor. How long it takes is dependent on several things.
1. How fresh is the battery? A recently recharged battery will recharge the flash capacitor sooner.
2. How far you are from the subject. If you are a long way, the flash must be stronger which will almost deplete the charge on the high voltage capacitor. That means it would take longer to recharge.
3. The design of the camera:
It is possible to recharge the capacitor in a fraction of a second, but that can cause the battery to overheat if you took several photos quickly. So the manufacturer chooses a safe recharge time for their camera.
Note: most cameras will take flash shots faster if you use "burst" or continuous mode.
I was deciding between 2 different megazoom cameras and I am trying to get some other opinions before I make the decision. I was trying to decide between the Kodak z812 is (the z712 is's big brother with a few more features)or the canon sx100 is. The Kodak has stabilized 12x zoom, 8 megapixels, and manual controls. The reviews i've read have said it tooks really good photos though with of course a few flaws. The bad side is the battery that is required for it is around the $30 dollars, and the charger another $30 unless you buy an off brand set. The canon has only 10x stabilized zoom but also 8 megapixels. 10x vs 12x isn't terribly important but what I don't like is it does not have an optical view finder and cnet said between shots with flash, the camera could have about a 5 second pause which might be too long. This camera also has manual controls as well. They both look like great cameras but I don't know. Tell me what you think. Thanks
