I think that is the point of the article. To quote the last bit of the article.the ENTIRE PIECE was based on MTF scores and pixel peeping, which have so very little relevance in real world shooting, especially when NOT looking at images at 300%.

"For practical photography not much really, other than just to make you more aware of reality. Here are the few takeaway messages for photographers:
But for measurebating, there is a very pertinent point that needs to be made: Measurebating zooms is a fool’s errand."
- A great zoom is not as good as a good prime at comparable apertures, but it’s plenty good, especially in the center of the image.
- Zooms have more variation, and most copies of a given zoom will vary at different focal lengths. If someone asks me for the best copy of a zoom, my first response would always be ‘at which focal length?’ In this case, the sharpest copy at 200mm is not the sharpest at 70mm.
We have more than our fair share of measurebators around this site. Not only regarding zoom lenses or lenses overall but camera bodies and brands as well.
He was far to wordy to get around to the final point. However his method does bring up one thought. When newbs bring concerns about a particular lens and some sort of softness issues it might be good to keep in mind that different copies of the same lens very well may not perform the same. All to often we see the standard, well there must be something wrong with your lens because mine is tack sharp at ***mm's, etc. There is a difference between different copies and an obviously defective lens. When the photos are so out of focus to not be able to tell what the subject was, that is a defective lens. If my copy at a certain focal length and aperture is sharper or softer than yours, that is often the nature of the lens.I think that is the point of the article.

most of that is completely negated if your using a FX zoom on a DX camera anyway...
"I" think the point of the article was for Mr. lensrental to show off his amazing pixel peeping and MTF score regurgitation abilities.
the entire article could have been summed up in one sentence.
"zooms are softer around the edges than primes, if your not shooting a FX lens on a DX camera, shoot a little wide and crop" boom. done. basic photography 101 stuff. didn't need a doctorate in digital engineering to tell us that. it was a totally overthought process for an underwhelming article.
but hey, its not like any of MY papers won any Pulitzer's.
yea, your totally right about measurebators though.

It used to be pretty common around here for people to talk about trying different copies and picking the one they like. I still do that. Many folks today think that mass production means exactly identical when it does not.
