Default Crop Question

Because I am going with a camera with not much zoom, (105) what megapixels should I be using so that I can later crop the picture to zoom it in a little. And will that then look grainy?
Thanks!!

Unless you have a specific goal in mind, the rule of thumb is to take the largest image that you can. You get better quality interpolating DOWN, as opposed to interpolating UP.

This question of file size was more important when memory cards were small AND expensive. I paid $700 for a 612 Meg card. With todays card prices, why worry about file size?

As far as cropping, why yes, the smaller the crop, the less "quality" in the image, but this also is a problem that is more or less academic, since the smaller file will crop even worse.

yes, always shoot max file sizes, cards are cheap, so no real reason not to today. that gives you the most latitude to play with it later.
