Sensor size P & S vs DSLR?
If I go to Nikon's site and see the specifications of the sensor can see a DX format sensor is 23.6×15.8mm and a FX format is 24x36mm, but if I look a little P & S sensor specifications see 1/1.7 "1/2.5" sensor for the "size". Therefore, I know math and you can divide 1 by a number, this is the diagonal of the sensor? Therefore, the hypotenuse of a right triangle? I'm curious to put in more than one type of apples to apples comparison. We continue to make statements like "DSLR sensors 15 times the size of P & S sensors "But it was only the number you want to back up the statement." Wiki, I thought to look there. You da man.
This Article should explain everything to you. http://en.wikipedia.org/wiki/Image_sensor_format
