Sure sends my blood pressure up to read something like that. I think this may be the most clueless in a long line of clueless group tests from Audubon Magazine and Living Bird Quarterly stretching back to the 1980s. Why oh why won't they learn how to perform some basic optical tests?!
I do despair when reading some tests in magazines. They seem to be concerned with advertisers and not upsetting anyone.
And adverts for cheap instruments, and some more expensive ones read like fantasy novels.
