Blog / Crop vs. fullframe given standard prime lenses

Since 50 mm is a universal prime lens in 35 mm format photography, many photographers choose 35 mm prime as a standard lens for cameras with cropped sensors. Can these two setups really be considered equal?

The angle coverage is nearly the same (not exactly because 35 mm focal length for cropped sensor gives a little more than 50 mm), but what about depth of field?

I’ve played with LensTutorial entering Nikon D300 (cropped) vs. Nikon D700 (full frame) cameras to see what it is like. You can easily repeat the same experiment for Canon or other brands using setup menu for choosing right models and makers.

Parameters:

Distance: 1 meter (3.3 ft)

Aperture: f/4

DOF for Nikon D700 with 50 mm: 9.3 cm (3.68 inches).

DOF for Nikon D300 with 35 mm: 12.7 cm (5.0 inches).

Now having the facts lets analyze them:
