This would be near useless for me and most folks I work with. Any modern production lens will resolve enough detail to keep you from getting a pink slip. I wouldn't project some lenses 40' tall but for youtube or even broadcast I would rank a lens' resolution numbers near the lowest of important characteristics for my uses as a cinematographer. The overall aesthetic performance of a lens is what matters, followed closely by ergonomics. The former is not something a lens review will tell you much about. You might be able to spot some bokeh and vignetting characteristics, but short of renting it and pointing it at a person and looking at them in a few sizes you won't know much about a lens. The only reviewer I see doing any work like this is Lloyd Chambers of Diglloyd.com: his in-depth reviews, aperture series, and expert commentary are worth every penny of his subscription costs. When the Sigma art 35mm 1.4 came out I rented it for a comparison to my beloved Zeiss ZE 35mm 1.4, and yes the Sigma could have an edge in resolution in some scenarios, but the Zeiss trounced it in terms of pure image harmony. Switching blind A/B on the monitor my crew all settled on the Zeiss. Just goes to show you DxO mark resolution numbers should not be a huge consideration in your purchases unless you are in the business of photographing and making reproductions of test charts.
