Camera manufactures keep trying to sell us raw pixels. They take the same 1 cm square of silicone and jam more pixels into the same space. Then tell us more is better. The problem is physics. The smaller a pixel the less photons hit. I’m serious it’s all about how large each pixel is. Most compact cameras use the 1/2.5″ sensor. More pixels, less space for each one = less photons of light. Here is a link to sensor sizes: http://en.wikipedia.org/wiki/Image_sensor_format
I have three Canon point and shoot cameras:
SD600 = 6 mega pixels
SD1000 = 7 mega pixels
SD1200 = 10 mega pixels
In spite of sensor improvements, the SD600 still takes better photos. The SD1000 and SD1200 are junk.
What does all this mean. Well unless you are looking at a new generation of sensor like the new Nikon D7000, less is more.
- Buy cameras with less resolution. You’ll be hard pressed to buy a camera with less than 10 megapixels.
- If someone tells you it’s got more resolution so it must be better. Walk away. They don’t know what they are talking about.
- The sweet spot most consumers need for resolution is about 6 megapixels.
- 14 megapixel Canon or 10 megapixel Canon point and shoot? I would pick 10 megapixel one every time.
Don’t believe me? The Canon S95 is a brand new $400 high end point and shoot from Canon. Its no mistake that it has 10 megapixels on a larger sensor 1/1.7″.
