If you wonder how shutterbugs get those sideline shots ... wonder no more!
Just thought I'd post a link to this great sports photo journalism site. It's patronized by most of the serious (re: good) professional photographers and by every wanna-be sports photographer.
SportsShooter.com
The shots are simply amazing and the discussions on photo techniques, camera features and related topics are pretty interesting, even to a "regular" photo monkey. (Just don't ask me to explain chimping to you.)
I agree with most of the stuff people have said on here and only have a few morsels of info to add. I've been shooting breaking news and sports for nearly 15 years. I'm a semi-pro shooter and also sold digital cameras at CompUSA between newspaper jobs.
Mega-pixels are important, but anything over 4 MP isn't really needed unless you intend to print the pictures larger than 8x10 or 'blow-up' a postage stamp-size portion of an image to full page.
If you're taking stuff you really want to keep, then make sure your camera shoots in RAW image files, as well as in JPEG formats. The RAW image is "EXACTLY" what the camera's sensor saw when you snapped the picture. JPEGs are compressed files, even after a few times of opening, editing and saving ... you will notice a difference in quality from the original RAW file as JPEG processing always throws away pieces of the picture to save file space. The more you edit/save a file ... the more of your original photo is being degraded and lost forever.
SLRs are definitely better as an investment than a "point&shoot", if only that you can become a better photographer and use more of their capabilities with new equipment (better or longer lens, faster zooms, remote flashes, etc.) You will be limited to whatever abilities the point-n-shoot has "built-in."
My biggest problem with point-n-shoot cameras is the delay from shutter press to image is taken. Like TAF said, it will work for a snapshot of a non-moving object if it is within 25 feet in daylight. If you want any thing else, get an SLR camera.
Digital Zoom is an illusion created by marketing stooges. The camera simply crops your photo and blows it up bigger, which is definitely not better in this case. You can do the same thing and better with any photo editing program. Stick to "Optical Zoom" or buy a better camera if you want to shoot things that are far away.
Personally, I have a Canon Digital Rebel EOS. Low-end of SLRs at just under $1,000, but it has all the capabilities of the same cameras used by true professionals. (6 mega-pixels, white-balance, fully programable, ISO (film speed) from 100 up to 1600, able to swap in any EOS-compatible lens for zooms, wide-angles, telephotos.
Buy a pair of memory cards that are as large as you can afford, you will likely use them. (I have a 1gig compact flash set) And after you download your photos, always FORMAT your media cards ... this is vital because otherwise you WILL get corrupted images at some point. A quick format or just erasing photos with the camera is not enough ... you don't want to lose that one unreproducable photo to digital gremlins.
