Which Company digital camera is the best? And for domestic purpose, tell the good resolution.?

Canon !

Another thing to consider is the memory card. canon uses CF and SD, depend on the model. I have 3 canon and a nikon, they all uses either CF or SD. These cards are cheaper and i can interchange. plug into multi-card reader or my lap top.

BOO Digital cams!! Go 35mm/120mm!!

Canon!!!

Olympus and Sony are real good for domestic purposes. U may search for a camera with a lens power of 6 or 7 Mega pixels.

NIKON...!!! 6MEGA is very good enough.

Nikkon 6 megapixel,will cost you around 18,000 and has got
very gud features

Canon is great, pricy but worth it

Hasselblad has the best and most expensive cameras.
They have a 39 megapixels camera.

Cannon is great for quality,
Sony Cybershots are good for the price,
Olympus' are more balanced.

try nikon cameras that are good
try 8 mp one

All of the major brands have good stuff (Canon, Nikon, Kodak, Panasonic, Sony, and Olympus). For a large part, it's personal preference. If you have specific models in mind, you can read in-depth reviews here:

For domestic purposes, 6MP is plenty. This will give you fantastic 1 page prints.
