Many publications, both in print and on the web, will test a product and give you a definitive rundown of its capabilities from that single test. Often, the results of these reports are at a variance to one another and some even go as far as total conflict! So are these differences in reviewers' objectiveness and methods, or are there true differences in the products they are testing? Is quality control at fault or is it bias amongst journalists?

This measurement is considered the best measure of testing lenses on modern digital cameras.
