This is a simplified subjective method of testing lenses optical sharpness. This should not be confused with tests for focus accuracy and discrimination in a 3D environment, that is a totally different issue although often confused by the inexperienced. A focus accuracy test is suggested here Focus Test. The advantage over this method, compared to just taking a shot of a garden etc, is elimination of variables such as subject and camera movement, insufficient depth of field, flatness of field and variations in focus location. It uses a nice consistent high contrast subject to make comparisons easy; checking sharpness on general photographic views is not very easy. As the method is subjective, it is worth testing against a known good lens for comparison.

Bayes’ theorem was the subject of a detailed article. The essay is good, but over 15,000 words long — here’s the condensed version for Bayesian newcomers like myself:
