Canon PowerShot G1 X 
The Canon PowerShot G1 X is a new premium compact camera with a large CMOS image sensor. Dubbed "the finest compact camera Canon has ever produced", the metal-bodied G1 X has a 14.3 megapixel, 18.7x14mm sensor that's marginally bigger than Micro Four Thirds cameras and full manual controls with shooting mode and exposure compensation dials. Positioned as a more portable alternative to a DSLR, the G1 X also offers an extensive ISO range of 100-12800, 4x zoom lens with fast maximum aperture of f/2.8, 3-inch vari-angle LCD screen with 920k dots, optical viewfinder, built-in flash and a flash hot shoe, full HD movie recording and 14-bit RAW image capture.

The main reason for the G1 X's increase in bulk is that it's Canon’s first compact camera to feature a large, 4:3 aspect, 14.3 megapixel CMOS sensor. Measuring 18.7mm x 14mm, it's almost the same height as the APS-C sensor used in manuy DSLR cameras, with the G1 X actually featuring the same pixel size and structure as the EOS 600D camera. This should add up to better image quality especially in low-light, greater depth-of-field, and greater dynamic range, all the things that your typical compact cameras struggles to deliver.
Photographers who love getting hands-on with their cameras will relish as we did being able to turn the G1 X's top plate rangefinder-like dials to select the exposure compensation and capture options from the shooting mode dial. The G12's ISO dial has been sacrificed, though, to make room for the new pop-up flash, replaced instead by a less satisfactory button on the rear, which makes choosing the ISO speed a 3-stage process. Another grumble is that, annoyingly for a creatively rich camera, the full user guide is provided on CD only. In what comes across as a cursory gesture, only a very slim printed quick start guide is included in the box.
