A number of great companies have helped me out in my career so far. I'm very grateful for the kit they supply and am honoured to be supported by some of the leaders in their fields.
PNY Technologies - http://www.pny.eu/ambassador/luke.massey
PNY specialise in memory cards. As a wildlife photographer I'm often shooting a lot of frames quickly, it's important I have a fast writing large memory card in my camera capable of writing all of these images without affecting my workflow. PNY's cards do this perfectly with Compact Flash and SD cards capable of writing at 100mb/s.
Swarovski Optik - http://uk.swarovskioptik.com
Spotting wildlife is a massive part of my work before even trying to photograph it. Swarovski Optik are the leaders in their field for scopes and binoculars. The quality of the binoculars they produce is outstanding and in low light the image quality they produce never ceases to amaze me.
Lowepro - http://www.lowepro.co.uk
The best brand of camera bags around. Lowepro have been around for years and I'm lucky to count on them supporting me in my work. When trekking long distances lugging 20kg+ of camera gear with you it is important to have a comfy bag on your back. Lowepro's gear is constantly improving with new ideas and taking photographers thoughts into account. Their range is brilliant with a bag for every kind of photographer.
Nite Watches - http://www.nitewatches.com
Nite are a British-based watch manufacturer designing and selling watches that are made to last. Their watches are perfectly suited for everything but the durability and ruggedness of them make them perfect for me whilst filming and photographing wildlife.
