Default Reducing MP when shooting...

Hi,
is it worth reducing MP when using a cam not DSLR.
I mean if you have a cam with 12MP, but 8MP is more than enough for me, will it make any difference in quality, noise and details to shoot at 8MP instead of 12MP?

I can still crop and resize pics with decent output size even at 8MP, so why using 12MP? (JPEG or RAW).

Regards

Reducing the resolution in the camera will certainly average out any noise.

Yes, there will be a reduction in quality and detail. The downsampling routines used in image editting applications and printer drivers are more sophisticated than the ones used in cameras. A 12MP image, printed at 4x6 will look better than an 8MP image printed the same size. A 12MP image displayed on your monitor will look better than an 8MP image, though the difference will be harder to see.

It's easy enough to see this for yourself. Try it, and if you are satisfied with the results you get, then you'll definitely benefit from the reduced impact of any noise, and you'll be able to get more images on your memory cards.

I would always use a camera at the mp it was designed for.

I read somewhere that this kind of sensor has its best performances when it's limit is 8MP, and not 12 or 14.
That's why I started this thread.
I do not need 12MP to print my pics... and it's not about saving space, as I have a 16GB class 10 sd card.

You really haven't clearly defined "best". If it's not about space, then shooting reduced resolution images doesn't buy give you any advantage. Downsampling on your computer will do a better job that downsampling in the camera.
