COMPARISON: ZEISS OTUS 85MM AND 55MM

[PedroS]

I'm a clinical guy... sorry for that 

For me both Zeiss just blow away the CV...

[Michael Erlewine]

I agree, but I am not a tester, just a user. I depend on you folks to explain why. I can the difference, but not know what exactly it is due to.

[Bjørn Rørslett]

The CV 125 is not performing at its best at f/16, a fact that has been known for a long time.

The 55 Otus photo shows signs of chromatic aberrations. The 85 Otus is so grainy and noisy that any CA would be swamped.

Why can't you shoot all of them at the same magnification of detail? The setup is flawed.

And start at f/2.5 (common lowest denominator) and go upwards.

[Michael Erlewine]

Sadly, not really a tester, and not much interested in learn. I agree, it was not a good test. The bottom line for me are what the Otus lenses produce as product. They are remarkable, and I would not use the CV-125 at narrow apertures... agreed.

Michael, I like your images a lot regardless of the APO lens used.
Looking forward to seeing some more

I am not an expert in the field at all so my opinion is of little interest, but aestetically, I find your stacked images much more pleasing than the ones you have been showing at small apertures, recently.
What do you think you gain by closing the lens? Obviously it is less work since you don't need to stack, but now the background is so present that it becomes intrusive. And from the little I know of you, the amount of work is not the decisive factor. I'd be interested in understanding your motivation.
Thank you !

The motivation is always the same, to push the envelope, experiment, and see what is possible with these (or any lenses) that I can work with. Also, I find it interesting to see what can be done with a single-frame  shot, etc. Often here in Michigan, which is flat, the wind is ever present, so if there is something that can be done in a single shot, that can be good. I shoot single-frame at high aperture or at other apertures. I stack wide-open or at other apertures. I never have arrived at the end, but always am in-process, learning.
