Amateur Photographer and Pentax have teamed up to offer five readers the chance to spend a day in London shooting with the weatherproof and splashproof Pentax K-5 II, while getting help from AP Editor and photographic tutor Damien Demolder.

The day will take place on 24 October 2013.

The five lucky winners will be taken out for a high-speed ride on board a RIB and each given a Pentax K-5 II for the day to use. They will be able to photograph the heart of London, including Parliament and Docklands close up, as well as running past the O2 Arena at Greenwich and through the Thames Barrier to the Olympic Games site and beyond.

Pentax now has a system of weatherproof and splashproof cameras and lenses that are ideal for shooting in challenging conditions – and when caught out in a shower. The K-5 II body, for example, has a stainless-steel chassis and weather-sealed magnesium-alloy shell, making it the perfect camera to use while racing along the Thames!

Pentax users also benefit from four WR lenses that are designed to be used in the wet, as well as weatherproof flashguns and battery grips. These WR lenses and accessories will be available on the day for readers to use, as well as a selection of Pentax’s brand-new HD Limited Edition lenses.

Join us for a thrilling day of photography and tuition, where the person who takes the best picture of the day will win a Pentax K-5 II.
