Is 4 Mpix camera just as good as 5 Mpix when available light is the limiting factor?

I'm shopping for a digital camera and I've narrowed my choices down to
the Canon Powershot A85 (4 megapixels) and the Sony DSC-W1 (5
megapixels). I'm going to be taking some indoor photographs that will
be enlarged to at least 8x10, maybe 11x14, with little or no cropping.

Given ample lighting and using the lowest ISO setting, I would expect
the 5 megapixel camera to produce a better enlarged image. However, I
expect the available light in my situation to be only adequate at
best, certainly not ample. Therefore, I will be forced to use a higher
ISO setting, which will undoubtedly introduce noise into the image.
Under these circumstances, wouldn't a 5 megapixel camera show just as
much noise as a 4 megapixel camera, thus reducing the overall image
quality and losing the advantage of having an extra million pixels?

You have to check noise by buying or by reading reviews such as
www.dpreview.com

There is no simple way to evaluate digital cameras as each user has
different priorities. Megapixels are important but are also over hyped by
marketers.

Noise is a function of the sensor size. Go for the camera with the
larger sensor, and the faster lens. The difference between 4 and 5Mp is
negligible.

Why not get the Powershot A95 (5 megapixels) and the price is just a
little bit more and performs better than the A85

Do you know how the A95 compares to the Sony Cyber-shot DSC-W1?
I'm buying a digital camera for my son and decided on the Sony DSC-W1.
It'll be used primarily for P&S baby pictures and vacation pictures.

Thanks,

Mike

Since I know nothing about digital cameras I'm trying to get all of the
information I can.

Both are good cameras, and each has unique features.

The W1 has a much larger 2.5" LCD (1.8" in A95), and a very fast full
autofocus shutter lag (wide angle) of 0.3 sec, pre-focus ultrafast lag of
0.01 sec - something that would be very handy for taking pictures of kids.
It also has a live histogram, pre-flash metering, etc. - for those who can
use these features. A little smaller and solid compared to A95.

But W1 has no shutter priority or aperture priority modes (A95 has both),
has a smaller aperture range of f2.8-f5.6 (f2.8-f8 in A95), only three ISO
steps 100/200/400 (A95 has 50/100/200/400).

Take your pick.

I can tell you from first hand experience that that A80 is crap in low
light, and really not practical to use above ISO100. Autofocus is poor
in lowlight as well. Manual focus is nice, sure, pictures are decent,
but not in low light.

Just reading some forums on the Sony, a lot of people saying it's not
to great in low light, and wishing they'd of bought the Canon, check
he

http://www.dpreview.com/reviews/read...key=sony_dscw1

If your going indoors, and could live with 3MP, I'd recommend the
Panasonic Lumix DMC-FZ3. Great in low light (for the price, very
great), autofocus actually works in poor light, flip up flash works
pretty well as a fill flash, and it cost a bit under $400. Oh, and 12x
optical zoom and Leica lens ain't bad either.
