Well, if it's a Canon or Nikon DSLR, or Sony Alpha, then YES!
Otherwise, I'm not sure yet. I'm using libgphoto2 (http://www.gphoto.org/proj/libgphoto2/support.php) as the interface library for cameras, so in theory a wide range should be supported, but some cameras may require special cases in my code on top of the library.
If you have a camera you'd like to request support for, please send me a message. I'm compiling a list of requests and will begin renting popular camera to add support for. Thanks!
