What's the points to consider in buying digital camera? and which brand can you recommend?

I recommend this brand and this model, it doesn't break the bank and I'm sure you'll get many years of enjoyment from it.

The best camera for under $200 is the Canon A550

* 7.1 Megapixel
*4X Optical Zoom
* Very good photo quality, noise levels low through ISO 400 (in good light)
* Well built for the price
* Very good performance
* LCD visible in low light
* Some manual controls
* AF-assist lamp, good low light focusing
* Good movie and continuous shooting modes
* Impressive software bundle
* Uses AA batteries; great battery life

my suggestion
go to yahoo shopping
digital cameras
digital camera GUIDE
be sure to check titles on the left side
the guide should answer your questions

All that info. and not a lot of help from any of them.

1) Decide what you will use it for;
-shooting family and friends get a point a shoot pocket one.
Casio Z75 is a great choice, nice and thin, lightweight, shoots photos and video with sound. Easy to use controls and a 2.5" screen to view.

-Shooting pro style you'll need an SLR (real) camera.
I reccommend Nikon brands, have great package deals for their camera bodys and lenses to start.

2) Will you be printing these pics or just e-mailing, This is how you determine the megapixel your camera will need.
-Making photos, go for 6.0 or more. Less if just e-mailing them.

Recommmend a Scandisk memory card, about 2GB.
Check you Sunday paper for ad sales or coupons.

Megapixels (<3, <5, <8, etc)
Optical zoom (4x, 6x, 10x, 12x)
Battery type (AA, AAA, Alkaline, etc)
Price
Memory type (SD, Micro, CD, etc)
Size (bulky, compact)

Canon, Panasonic, Nikon
I have a Panasonic FZ20

I would like to highly recommend the purchase of a Nikon Coolpix L10 for the following reasons:

1. Besides taking well-exposed hi-quality 5 megapixel pictures, it uses a standard set of rechargeable double AA batteries which last a very long time;
2. Has a 3x optical zoom;
3. The flash setting for "red-eye" correction is on the navigator wheel and not within a submenu;
4. It's very small and light;
5. Uses inexpensive SD memory cards;
6. The digital video feature takes wonderful "sound" videos which are noise free. It records the piano very well with it's built-in microphone;
7. And the price is a mere $120 [sold at Samy's Camera, Staples.com.]

Good luck!
