This week’s Sunday Morning Photographer column from Mike Johnston is rather off-puttingly called “Parameters of Lens Specification and the Properties of Lenses”, but it’s actually a lot more interesting than the title first suggests:

“I’ve been known to have a pretty jaded and cynical and sometimes even (heavens!) sarcastic view of “lens tests.” I feel for the most part that they’re relatively useless. It’s not just that lens tests are sops to insecurity, although they are that. It’s not that most of them are silly, or misleading, or wrong, either, although they are often that, too. It’s that, often, they’re just not helpful at all.”
