zooms on digital cameras I noticed there were two types of zooms offered on digital cameras. I've heard that the optical zoom is the more important. I was wondering if you had an idea of what a 2x zoom or 3x zoom was compared to a traditional zoom lens for an SLR? Thanks

The two kinds of zooms on digicams are: 1. Optical - which is the same as you have with a zoom lens on an SLR. It's in the lens. 2. Digital - which is kind of smoke and mirrors. It is not so much a zoom as a digital enhancement. It is almost certainly accompanied by a loss in image quality.

Doreen, Zoom power on some digital cameras use 35mm SLR "equivalent" numbers. For example: The Nikon Coolpix 5700 has an 8X zoom this means that from its widest setting, it can zoom (optically)to magnify the image eight times over. So, it zooms from an equivalent of 35mm to 280mm(8x35=280). Or in true terms 8.9 to 72mm(8x8.9=71.2) Like Jeff said, digital zoom is just a trick not worth a hoot in my opinion.
