The inclusion of full 1080p movies, built-in GPS, 10fps burst shooting, and an excellent LCD screen should also help to make the Sony A65 a real contender to equivalent offerings from the Big Two of Nikon and Canon.

Raw files also offer the capacity to fine-tune the colours post-shoot, as well as providing the opportunity to pull extra detail out of under and slightly over-exposed areas in high contrast images, allowing you to get the very best from the A65's superb sensor.
