I hate it when Canon users say that a Nikon is not capable of something. Well there is one thing that Canon camera's do better. Exposure ramping or bulb ramping. Imagine you want to create a time lapse movie of a sunset. Normally you would do that with a fixed shutter speed. But then your movie will become darker and darker when the sun sets. Wouldn't it be great if you can make the shutter speed longer after each frame? Then the day will go into the night and the night will have the same exposure. This is where bulb ramping comes in. You control the camera via a remote control while the camera is put in bulb mode. The controller can then determine the shutter speed of the images. Canon camera's do this very good. You are able to control the shutter speed of the camera very precisely. But not with a Nikon. Nikon camera's use discrete steps in their bulb mode. Why? Only Nikon knows, but this is a serious flaw in their camera design.
