Information that you need to compare
Max resolution 2816 x 2112 (it tell about Mega pixle, higher is better)
Low resolution 2272 x 1704, 1600 x 1200, 640 x 480 (more option are better)
Image ratio w:h 4:3 (if 16:9 is also that good)
Effective pixels 6.0 million ( actual photo resolution, higher is better)
Sensor photo detectors 6.2 million (its electronics resolution,actual no. depent on this, and manufacture tell this no.)
Sensor size 1/2.5 " (1/1.8" is better)
Sensor type CCD ( go for CCD not for CMOS)
Colour filter array RGB (All CCD support RGB)
ISO rating Auto, 80 ,100, 200, 400, 800 (for low light higher is better, some of camera are availabe with 1200, but 800 is ok)
Zoom wide (W) 35 mm (>35 is good)
Zoom tele (T) 105 mm (3 x) (it is optical zoom, highre is better,Zoom_tele/Zoom_wide tell you optical zoom value)
Digital zoom Yes, (its help to see photo on camera's LCD only, not help full in other ways)
Image stabilization Yes( for higher optical zoom/shaking hand, it must be)
Auto Focus Yes/no( deped on user's smartness and experence, for ist use auto focus is ok, but for advance photography, its not require)
Manual Focus Yes (must fot good photos but need setting per photo)
Auto focus type center (it should be "AiAF TTL 9-point" and "center")
Normal focus range 55 cm (minimum gap frpm object)
Macro focus range 1 cm (its good value, upto 5CM ok, its for closeup photos)
White balance override 5 positions plus manual (higher value is better)
Aperture range F2.8 - F4.8 (bigger is better but it also make big size camera)
Min shutter 15 sec (good value)
Max shutter 1/2000 sec ( good value but if you are getteing 1/2500,1/3000 that will be very good)
Built-in Flash Yes (must be to take photos in dark)
Flash guide no. 3.5 m (11.4 ft) ( 5m minimum or higher)
External flash Yes, (not required for compect camera)
Flash modes Auto, On, Off, Manual (Red Eye On/Off) ok

Metering Evaluative, Center Weighted, Spot OK
Aperture priority Yes
Shutter priority Yes
Lens thread Yes, with adapter ( to add more lens to increase optical zoom)
Continuous Drive Yes, 2.0 fps, unlimited (faster is better,4-8fps)
