Digital photography

Just another camera system really. I was happiest back in the D200 days Ergonomically and intuitively. Latest batch of Nikon's feel pathetically dinky and the latest Canons feel cheap even when you're playing with a MKIII.

Done it? Yes, It's comparatively easy to DO. Just re-learning where the buttons are and using them without looking and when situation requires. Worth it? In what sense? What are you trying to accomplish?
For me, It was useful but unnecessary as the type of images (When I needed video I went back) I take required speed and very little else. I had to see something coming and change my settings before the camera is even up to my eye. For that, Nikon won for me.
Saying that however, the only thing I say is...go hold the camera in your hand. Seriously. If it feels easy to use and right to hold, it's probably a system you'll end up prefer using.

Thanks. Helpfull. My 700s are perfect for the reportage style I work with, but they need replacing soon. Nikon are dicking around with either stupidly expensive, or retro. So currently the best camera on the market for me is a Mk3. Time to make the trip to Photolease....
