Stock Shot Project

Here are two shots of the same object, a computer keyboard, done with two extremely different focal length lenses.  The photo above was taken up close with a 10.5mm Nikon fisheye lens on a D7000. 

This image was taken with a 400mm Nikkor telephoto fit with a long extension tube so it would focus close up.  On the D7000 with its APS sensor 400mm is equivalent to 600mm on a full frame camera.  These two photos illustrate the difference in perspective and depth of field due to the different focal lens.  The wide lens expands space, while the telephoto compresses it.
