We've teamed up with Pentax to offer two of you this handily compact yet unexpectedly powerful Optio S1 camera - perfect for slipping in your pocket this summer. Just 20mm thick, the Optio S1 might be ultra-thin but still comes packed with functionality including a high-definition mechanically stabilized 14 megapixel sensor, a 5x wide-angle optical zoom and 22 different scene modes. It also features impressive HD video recording, which is easily viewable on the 2.7’’ LCD screen. For the full specs, here's the Pentax website.

For your chance to win one of the two chrome Optio S1s, email online@esquire.co.uk putting ‘Pentax’ in the subject head. Good luck!
