I do indeed, Canon 550d, nothing too fancy, but more than enough to have a good crack. just the usual twin lenses, plus a fisheye. The thing I find most frustrating is getting focus set to "∞" correctly - often the images I capture look good on the camera screen, so i keep shooting away - only when I get home they're crap. Easy enough when there's something to focus on
The other thing that gives me the violet is the memory - take a few shots - maybe 10 or so - no problem, but once the buffer's depleted, you can wait 20 seconds or so for it to be ready again!
Even got an ultra SD thinking that would help...
I guess it usually comes down to practice makes perfect, and a little luck too!
