Without a price range I cannot suggest a particular camera.
I would only look at brands that are well known, and currently developing new cameras.
Having the highest number of megapixels (MP) is not a good guideline.
Somewhere around 12MP is the sweet spot.
Any camera you buy will have some digital zoom, but don't use it. It degrades the pictures.
Optical zoom does not degrade the picture and ranges from 3X to about 50X.
Don't buy more zoom than you need on a daily basis.
More optical zoom adds weight and cost.
3X is sufficient for most people.
Remember a very small camera will have a very small battery.
Battery size determines how many photos you get on a charge.
I am planning to buy a digital camera but m confused which one to buy.my usage is limited to clicking my family photos and nothing else.i want to k ow what are the parameters to see when buying a new camera and also what you people recommend for a beginner in photography?
