Many photographers have a clear preference for one brand over the other, and we are committed to supporting both brands. But there are differences in the live view implementations of Canon and Nikon cameras. Here are the ones we think are most relevant to stop motion animation.
The Nikon live view size is 640x426. This is perfectly adequate for most animation, but smaller than Canon live view.
The Nikon live view acts more like a video camera, constantly adjusting to the lighting of your set.
The Nikon live view often overheats the camera when shooting in a poorly ventilated room, under strong lights, for extended periods of time.
Note: Dragon Stop Motion automatically rests the live view when you step away from the program. However, if you animate for hours at a time, the live will not get a chance to turn off.
The Nikon lifts its mirror to provide live view. To shoot a picture, it drops the mirror, opens it to expose the sensor, then drops the mirror again. (In other words, it uses the mirror as the shutter.) Dragon Stop Motion must then open the mirror again to return the camera to live view mode. This process can be fairly loud, and the turnaround time is slightly longer than the Canon.
