"We had previously published the Consistency number for 24mm lenses, so I'll include those in a table for comparison. Wide angle lenses tend to have more variation, so we hoped the 50mm lenses would have less variation than the 24mm lenses."

Would it not be more correct to state that the variation of the lenses (50mm and 24mm) is similar, but that at wide angle the same variations show up in an "amplified way" with wider angle lenses in MTF tests?

If you take the focal length into account, the 24mm QC seems on par with the 50mm lenses?
