Add more pixels, please. August 20, 2007

I’m getting dismayed by the fact that marketing has seem to overrun good common sense at the camera companies these days. Perfectly good cameras like the G9 are coming out with 12 megapixels now and that’s just stupid. That camera, in particular that sensor, shouldn’t need more than 6mp, in fact it would make the camera better.
It’s even worse because for if a moment it seems like the megapixel race might be over, they start doing the ISO thing. But now it seems they’re going to do both as the same time, a guaranteed recipe for disaster. 12.1 megapixel and 1600 ISO in a 1/1.7 sensor; now unless I’m mistaken (and I may be, I had to wake up way too early today) that’s a pixel pitch of at best 1.9 microns. That’s pushing it too far. Sensitivity, efficiency and dynamic range for a sensor like this are all going to suffer. The noise is going to be high! Noise reduction might make it look better but it smooths out the details and what are you left with? A camera that is probably equivalent to 6 megapixels of useful image data on a good day. One could do the calculations by making some assumptions and figure it out, but it doesn’t matter.
I’d like to see manufacturers start focusing on better lenses and larger sensors. Move to lower resolution, there’s no practical need for sensors like this in these cameras. More resolution can be better, but it isn’t always.

I couldn’t agree more.
