Need some advice on buying a new camera, my old digital is on its way out. I've been looking at this one click here would like your veiws on this model and or other suggestions you may have. Is the meg pixel of 7 high enough or should i choose a higher one?
Higher pixel pitch (assuming a fairly equal spacing) = smaller photosites = less light per photosite = a requirement for greater sensitivity. This can and usually does increase noise. Look at how hard Canon had to work to add 2MP to the 30D's successor without actually increasing the noise. Look at the D3's low pixel count and its low noise.
for good reviews try this click here also a camera with 6-8 megapoxels is good enough to make pictures of at least a4 size. i got a new camera last year and after a lot of research i got a canon a640 from camerabox for £200 plus a £60 rebate from canon such a good deal and i am so pleased with the camera. there are good deals to be had just look around. think what your needs are and then look at reviews online. best of luck
