I am looking for a starter camera for deer photography. I want a small point
and shoot to start with. I like the Powershot G7 (10 megapixels with 6X
zoom), and the Powershot S3IS(6 megapixels with 12X zoom).
Is it better to have a bigger zoom, or a bigger megapixel to crop on my
computer?
Thanks,
Joe |

One figure of merit is to take the square root of the number of pixels
and multiply it by the zoom ratio. The result is a figure of merit in
terms of resolution to compare cameras.
Why "square root" of no. of pixels? Because resolution is usually
considered in linear terms, and the number of pixels is equal to the
number of pixels horizontally times the number of pixels vertically.
Thus the square root is the average of the number of pixels in each
direction, or linear resolution.
With the ubiquitousness of electronic calculators these days, taking a
square root is no longer a task in higher math. In fact, Windows
accessories includes a calculator. Bring it up and select the
"scientific" option, which includes square root. >> Stay informed about: Megapixel vs. Zoom |

I know that the S3IS is stabilized, something to think about
if you're gonna do a lot of long tele shots I don't know if the G7 is.
G7 is a great P&S, but my next camera will probably be an S3IS.
