Advantages of 4MP Digicam over 3MP?

Assuming all features (Optical zoom, movie mode etc) are the same, is there really much image quality advantage of a 4 megapixel camera over a 3 megapixel camera? I know the 4MP can probably produce better 8x10 photo prints, but how often is that going to happen anyway? Anyone know of other reasons to go 4 over 3?
 
Depends on what you need it for. 3mpx will do fine for 8.5x11 prints, but you may want more megapixels for larger prints.

More megapixels can sometimes be a bad thing. For example, the 4mpx Canon S45/G3 cameras arguably produce better images than the 5mpx S50/G5 cameras because the lens size is better suited to the 4mpx sensor size.
 
I remember last year when everyone was saying 2 megapixel was more than enough.

If you like to crop and enlarge images, your better off getting the 4mp one. Providing everything elso is equal
(lens,optical zoom ect)


I really want to upgrade my Olypmus D510 (2.1MP) to a A70 but just cant convince myself that a 2.2 to 3.2 megapixel
increase is worth it.

peace

Do you have a budget? The Canon S45 and G3 are great 4mpx cams.

My budget is somewhere between 250 and 400 at this point...obviously prefer the lower, but not at the cost of having to upgrade in a year or so. I am looking closely at the A70 also, but the A80 seems attractive too, for the 4MP. BUT I also like some of the cameras with 6-10x optical zoom (olympus and fuji come to mind). I know the A70 is a fav around AT, anyone use the A80?

I like the G3...but I can't see myself putting out over $500 right now. I like the size of the A70, small enuf to fit in a jacket pocket but not too small for my big hands. I think the G3 is pretty big, no?

 
The A80 is fairly new. There may be a few people over at the DPreview.com Canon Forum who can comment on it. In order to get 6-10x optical zoom, you'd have to get a digital SLR and a good telephoto lens. Any camera with 6-10x zoom will be expensive, well out of your price range.

I'd consider the Canon S45 at $348. But go with the A80 if you prefer AA batteries and that swivel LCD.
