Input:
User Review: After months of exhaustive searching, I finally decided to purchase the Canon Powershot G2 (it's a wonderfully re-designed upgrade to the Powershot G1).  The clarity of the images that this camera takes is spectacular.  Combine that with the list of outstanding features that aren't included on any other digital camera: ISO 50, RAW image capture, a flip out LCD screen (which is much more handy than you would think), an infrared remote for long exposures and self-portraits, and easy menu functions -- this camera is without equal in it's price range.
It's definitely not for the beginner, but, if you're familiar with photography, you'll be able to take sharp, beautiful pictures with this camera.  Skin tones are perfect and the built in flash with exposure compensation does a good job for portraits.  And, if you're considering a Sony, this camera uses the more inexpensive Compact Flash memory storage system.  Compact Flash memory cards are cheaper than the Sony Memory Stick and are compatible with more peripherals than Memory Stick.
All in all, if it's in your price range, you will be very pleased with the Canon Powershot G2.
