The Canon SX2600 HS has a 4000x3000 pixel sensor with a pitch of 1.54 microns. The lens is variable and can be set to a lot of different settings. We suggest starting with something in the 5.5 mm range for the focal length. The sensor size is calculated for you if you have the resolution and pixel pitch.
We will add this to the pull down list since it is a common camera that geotags well.
