Sigma dp0 Quattro

Aperture Series: Creek Enters Lake

This outdoor scene assess image detail near to far and across the frame at closely-spaced apertures (4, 5.6, 7.1, 8, 9, 10) to assess the effects of diffraction and depth of field on a very close range to distant scene.

Sigma dp Quattro utilizes an APS-C sensor. Versus a 35mm full-frame sensor, f/4 has the depth of field of f/5.6, and thus f/10 is equivalent to f/14.
