20mm Comparison: White Mountains

This test is of a landscape scenario at far focus (near infinity). The mid-day lighting was a good time of day to put aside creative photography and make a comparison under harsh but reasonably consistent lighting.

Lenses used:

The scene was chosen to provide a wide near/far perspective, to show off any field curvature issues. There is not an exact match in angle of view between the lenses, but it is of no consequence, since the gross differences are obvious.
