Got it..the smaller the sensor the greater the density the smaller the pixel the noisier the image. The crossing point is that place where you make a noise/image choice. Jack --- graywolf <[EMAIL PROTECTED]> wrote: > No, the smaller the pixel the more noise. > > graywolf > http://www.graywolfph

The problem comes if you keep the sensor size fixed; does the extra resolution you get from more megapixels outweigh the decrease in signal-to-noise ratio (assuming comparable technology; this years 8MP sensor way well have a better signal-to-noise ratio than last years 6MP). There has to be a poi

I've been wondering about this myself for a while. Reviews that I've seen of the Olympus E300 make a big deal about its 8MP resolution in comparison with the 6MP of the *istD, DS etc and the comparable Nikons and Canons. But the reviews never mention the smaller sensor size of the Olympus. All e

There's no one definite answer - it's a personal decision. Obviously, for a given megapixel count, a larger sensor will be better. The problem comes if you keep the sensor size fixed; does the extra resolution you get from more megapixels outweigh the decrease in signal-to-noise ratio (assuming

- Original Message - From: "graywolf" <[EMAIL PROTECTED]> I think that right now in consumer grade sensors a 6mp APS size sensor is about optimum which may explain why the makers don't seem to be in any great hurry to increase megapixel counts on the semipro cameras. Except that som

Are you asking at what point the signal-to-noise ratio becomes more importatant than pixel count? Sounds like a pretty simple question, but it is not. A small sensor 2mp camera is adequate for web use. An astronomer wants a camera that is not going to generate a noise pixel when the point sour

I'm not an engineer, but I don't think there is a definitive answer. It's a moving target. Sensor quality varies. It's theoretically possible, although perhaps not likely, to produce an 8 megapixel APS-C sensor that has less noise than an 8 megapixel full frame sensor. At the same time, I suppos
