I kind of expected something more than 2mp.
- EricE 4y agomore pixels mean the smaller each sensor for each pixel is and the less light each sensor for a said pixel can gather. Quantity does not always equate quality, especially in photography.
- myself248 4y agoLower pixel count means larger individual pixels, which increases their quantum efficiency. This gets you more accurate information about the light itself; think of it as more bit-depth. In scientific applications especially, this is often a better tradeoff than going the other way. If you need fine detail of distant objects, do it with lenses rather than raw pixel count.
