A 25mm lens does not have nearly as deep a depth of field as the silly claims one often comes across. The leaf here is a few feet from the camera, and it takes until f/16 to sharpen up the background, which is not to say that the most successful result is at f/16; that provides increased depth of field, but that by itself make a picture better.
The goal here was to show a near/far comparison to illustrate how the 25/2 Distagon renders when focused at close range. The lighting was very dull and blue, so don’t expect too much out of the color rendition here.
Example — Leaf on log with creek
This image take deep in a canyon in the San Francisco Bay Area— very blue and dull light, using the 21MP Canon 5D Mark II, and Live View with a remote release.
The point of focus (the leaf) is approximately 3 feet from the camera.
