I've been taking the Sony A55 out on the skis to test its action shooting capability. When I first read about it that was my interest. I saw that it was fast, small and light and wondered if it would be a good backcountry action sports camera. I think the answer is yes. The only issue I've had at this point is that the auto focus has a little trouble in the snow. And snow is about as tough an AF problem as you can get. It's like trying to focus on a plain, white wall.
I've posted a couple of A55 sequences on the Sports Photography Forum and wanted to share something on the Sony forum as well. So here's a snowboard photo I really like, taken at Solitude ski resort. It was shot at ISO 800 and it's been pushed really hard to pull snow detail. Lighting conditions were tough that day.
