DSLR Camera and Interchangeable Lenses?

Q. What is a good DSLR camera with fast shutter speed?
Can lenses fit on a camera even if it is a different brand as long as the mm matches?
Ex. Can a Canon 18-55mm lens fit on a Nikon camera with 18-105mm?
Asg?
Thanks. I was just using Nikon and Canon as an example. :) I have lenses but can't find the camera brand anymore so was wondering if they could be used on different brands (like the Canon/Nikon example)


Answer
Not sure why you need a fast shuter speed camera. You know in theory, faster the shutter speed, the less clarity your image become? And most of fast shutter cameras work better with wider aperture lens to achieve the benefit. But these lens are extremely expansive. i.e. Canon 85mm 1.2L cost $2000+.

what the zooming capacity for a 18-55 mm dslr camera lenses?

Q. i mean the optical zooming capacity? What is the closest thing it can focus?


Answer
The zoom capacity (a term usually used in compact p&s cameras) is 3x as 3 x 18mm = 54mm. As for closest focus, this is the information for the Nikon 18-55mm. Other brands may be similar.

Close Focus: 11" (0.28m) from the back of the camera. This is 4.5" (11.5cm) from the front of the lens.
