Interesting new macro lens with long working distance
« on: December 04, 2019, 09:21:17 am »

https://www.dpreview.com/news/6021330500/zy-optics-announces-its-mitakon-creator-85mm-f2-8-1-5x-super-macro-lens

Available in many different mounts, has a nice working distance, 10" at 1x and almost 4" at 5x. Hopefully it is good optically.

I was looking at that online yesterday. About $500 I think it was. Also thought it interesting.

I fail to see what the fuss is about. My Voightlander 110mm macro has a working distance (front of lens to subject) of 10-11" at 1:1. And it's my understanding that there is a fixed optical relationship between focal length, subject-lens distance, and lens-film distance.

The  reproduction ratio of the Mitakon goes from 1:1 to the maximum of 5:1, the maximum reproduction ratio of the Voigtlšnder is 1:1.

The canon 5x macro is 65mm, so this is better, at least on paper.

Yes, but we are talking about working distance, no?

The lens-object distance for a given magnification depends only on the focal length d = f(1+1/m).

For 5x macro, this Mitakon lens should have d = 85mm (1+1/5) = 102mm, and the Canon d =  65mm (1+1/5) = 78mm.

Mind you, these measurements should be taken from the front nodal point, not from the front of the lens, but that maintains the same correlation as the working distance. Longer lens means longer working distance.

Take a look at the PetaPixel review:

And I quote: ď Wide open, itísÖ itís the worst macro lens I have ever tested. By a large margin. Itís foggy, blurry, hazy, and just wrong.ď . . . ď Even when stopped down, itís still the worst lens . . .Ē

Enough said, I think. A $500 paper weight or door stop.

Too bad but I suppose the upside is Iím not tempted to spend yet more money on equipment.
