Originally posted by nzondlo A lens that is being claimed as an Otus-killer I want yo see how well it holds sharp focus wide-open at close to medium range, what its fall-off rendering looks like, and fringing in high contrast areas. Some of those characteristics were highlighted but these are supposed to be marketing images for a portrait lens so I want to see the reasons we'd even want this lens to be shown off prominently and attractively.
I don't understand why this opinion is so offensive and the ad-homs are coming out.
You should have reported my exact terms in stead of being a lot murkier: " I previously wrote that according to its formula (front bi-concave lens), this new Pentax lens should be compared to Zeiss Otus 85/1.4. And as I said, I am sure this lens is a must-have for the one who needs it..." It would have been a much more respectful behavior.
I am not a Pentax fan in terms of blindness. I own vintage Leica-R lenses when I discovered their supremacy in terms of micro and macro-contrast in past century. At that time, I tried Minolta, Nikon and Canon lenses (not Pentax I didn't know at that time). I loved working with Nikon cameras and some of their lenses are very good. I didn't like Canon lenses mainly because of CA. At that time (I tried Leica Summicron-R 50/2, Leica Summilux 80/1.4, Leica Apo-Summicron-R 180/2), I felt obvious to switch to Leica lenses (I used to mainly work on B&W Tri-X rolls and Kodachrome 25 and Fuji Velvia 50 slides).
Leica as everyone knows unfortunately abandoned Leica-R mount when switching to digital era for the benefit of Leica-S mount. I had Canon EOS 5D Mkx for convenience: I didn't want to change the original mount for a Leitax one although I always found their weak sensor as a stumbling block.
Then, Pentax K-1 has been released in 2016. I found the design of another era, old fashioned... Until I tried one with the Pentax HD PENTAX-D FA 24-70mm f/2.8 ED SDM WR. I didn't like the lens (excellent but not my taste) but I understood the potential of the camera thanks to the RAW files I worked on and the feelings I had with the camera: a joy to hold it in my hand. Changing original mount is not so easy nor psychologicaly obvious, but I did with some of my Leica-R lenses. I couldn't be happier.
Perhaps I change one day for another brand EVF camera, but the Pentax K-1 is still the one...
To resume, Pentax undeniably made an excellent lens with the new HD PENTAX-D FA★85mmF1.4ED SDM AW, but the limited edition is still an excellent option for those who like (like me) mechanical aperture, small lenses...

If I had no Leica-R lenses today, as a neophyte, I probably would go for two Pentax K-1, one with HD PENTAX-D FA 15-30mm f/2,8 ED SDM WR and one with HD PENTAX-D FA★85mmF1.4ED SDM AW according to my use...
