When trying to steer people away from the trap of looking only at megapixel count, I often talk about other factors that go into a digital camera's performance. As a general rule, I rank them as:Add Shutter lag
1) Lens quality
2) CCD size
3) pixel count
How do you tell newcomers how to assess the zillions of digital camera choices out there?
1) Lens quality
2) Sensor pixel size
The real parameters are:
2a) Full well capacity in electrons
2b) read noise in electrons
3) Full Press Shutter lag
4) pixel count
5) metering accuracy (prevents high end blow-out).
Given that lenses tend to be pretty good, Lens quality might
be lowered, depending on uses. Saying CCD size might get
misinterpreted as number of pixels. Also, if you had really big
pixels, the lens does not need to be as good as with small
pixels, given the same number of total pixels.
