I've recently acquired a Canon 5D Mk1 (used, of course) and am trying to get the hang of it. It's a little tricky using it compared to the 7D, which has been my primary for the last couple of years or so. A lot of the controls feel like they're in the wrong place and its ergonomics just feels off.
Anyway, I took it out to shoot some landscapes earlier this week for the Project52 'Sunsets' theme. This one was taken in the deep SE of Calgary, not too far from the city limits.
