p.10 #4 · Mamiya ZD: First Impressions | |
The relative softness after f11 exists independent of sensor/etc. (Although, of course, if you are cropping film to 80% of area, or using digital sensor, then you will have less softenss as you aren't capturing the edges.) I have compiled over the years all of the resolution tests of the various Mamiya lenses, and have them in Excel. Most (all, perhaps) were done by PopPhoto on film. Thus, these results are independent of all things sensor related. As you can see from the pic, its not so strong you can't use over f11, its just a trend.
You'll note that these numbers are equal to, and in some cases, exceed those from Zeiss or Hassy. The Zeiss or Hassy lenses, across the board, do better on the edges (although sometimes not by much!) and can have better wide-open resolution, for example. Basically, it is similar to what is being said here about the backs - you do get more from the Hassy or Zeiss MF options, but they cost gobs more. With Mamiya you are already wayyyyy up on the performance curve, farther than many realize. And in various small areas, actually better!!
The corner numbers are dashed and the solid ones are center. The legend says 'o' for cOrner (both corner and center start with 'c', so I went with 2nd letter on less important word).
These aren't the best colors and all that for differentiating between lenses, I had just made the chart for myself over the years and not for public consumption, but since Frank asked about over f11 resolution and this is my information, I decided to post it.
Oh, and the 120 macro was tested, but only qualitative expressions of how it did were published. I've asked PopPhoto for the actual numbers to my little chart here, but have gotten no response yet.
