i want to buy digital camera, any advice ?

Canon are very good cameras, I use one at work and both I and my wife have our own. The quality of the lenses and the features on the camera in my opinion are far better than other brands of a similar price.

It depends what you want it for, if you are just looking for something to take holiday snaps then why waste money on a 5 megapixel, 3 would be sufficient for this, if you are wanting to be more creative and wish to manipulate then yes go for the bigger one. I would suggest you go to a dealer and discuss with them your needs, budget etc.

What ever you get, enjoy it.

Happy New Year.

for quality sony is the best,for price i think hp is the best...

Well the better thing is that you should visit online and check the features. The best features that you want select the model and company and then buy it.
