You will be pleased with any of the three.
I would pick the Canon SX260 because it only has 12MP, which will give you photos with less noise.
The other cameras has 16MP sensors which are too many pixels for such a small size sensor.
The camera makers have to use noise reduction firmware which will also remove the smaller detail.
The Canon SX500 uses older technology (CCD sensor instead of CMOS sensor.
CMOS is much faster when shooting in burst (repeat) modes.
I wanna buy a new camera and i'm thinking about one of these 3:
Canon PowerShot SX260
Canon PowerShot SX500
Nikon COOLPIX S9200
I'm not an advanced (not even a beginner) photographer, I want a solid camera, good zoom, good quality, hd video and light to carry around.
Plus,I want it to have enough advanced features having the possibility of using them in the near future.
The most important thing is quality of photos, day&night, and probably ease of use.
Other recommendation would be greatly appreciated.
