Interesting. Unless I'm misunderstanding, that approach would show you the curve of each lens and the optimum aperture for that lens, but wouldn't necessarily tell you which lens is the absolute sharpest, correct? All will hit 100%, or 1.0 at one point on their curve so you'll know that f/8 is the best point for your 50MM, and f/5.6 on your 35MM, but your 35MM might still be sharper at f/8 than the 50MM even though that's not the optimal point.
Am I thinking about this correctly?
Makes sense.. Perhaps I misinterpreted.. This was his direct quote, and now that I re-read it, I think he's suggesting normalizing based on the maximum QoF value across the lenses.. so if your 135L had the highest QoF value, that is our 1.0, and all other QoF (across all lenses) are measured compared to that maximum value..
Of course that quote also implies that focal length has an impact on QoF value, so I'm not sure how a direct comparison could be made.. Perhaps standardizing focal length and distance, so all lenses tested must be 50x FL or some other ratio.. I wonder if that would help equalize the focal length and distance components..
He did say he's adding more a long these lines in the January release, so maybe we can get some clarification then.
