As some people know about my gear, I have Leica-R lenses with Leitax mount for my Pentax K-1 (II). Recently, I bought a Panasonic DC-S1 camera. I Iove both worlds for diffèrent reasons. Anyway, I have a lot of pleasure to get out with my Pentax K-1 since I think it is the best DSLR camera in the world to offer best compromise between resolution, IBIS and Raw process and the pleasure of OVF... :cool:

The Leica Elmarit-R 28/2.8 E55 ROM is a fantastic lens. ;)

Hello The Squirrel Mafia,
thank you so much for your kindness. I do not use the PDCU5, it doesn't work so well on my computer (unstable with MacOSX) but that's good news for RT users. I work sometimes with Silkypix and I dare to understand that's a similar product to PDCU5 about rendition.
About DxO PhotoLab, that's a pretty good idea to compare noise reduction between the two softwares.
Thank you again. :rolleyes:

I hope so for KAF4 lenses' owners.
I wish Pentax staff the success they deserve.
About CA on HD Pentax-D FA ★ 85 mm f / 1.4 SDM AW, at contre-jour, the issue is not, in real life. You can see some CA on samples, that's right but at 100% crop. That's not significant according to extremely challenging and difficult conditions. It does not affect the perfect rendition of this lens IMHO. It reminds me the Walter Mandler 3D effect you can find on Leica Summicron-R 90/2 (pre-AA) or Leica Elmarit-R 180/2.8 ver.II (pre-Apo) where bokeh is magical.
I have KAF Sigma ART 35/1.4 lens. Nobody talks about extreme distorsion at low distance with this lens which looks more fisheye than a wide-angle lens. And nobody talks about the distorsion control at all distances of the new Pentax HD D-FA SDM AW 50/1.4 and 85/1.4. IMHO, it is more important to notice than a little of CA in huge conditions... :)

Again, I didn't predict the demise of Pentax but of a system. It happened to Leica for the R-mount for the benefit of S-system and L-MILC system.

If KAF4 still exists. That's why I do not feel concern with mechanical apertures (by ring): you can fit these vintage lenses with any brand new EFV camera, not worried about that.:)
If the formulae are comparable, yes. Otherwise, it's not.
Probably comparable formulae between new D-FA AW SDM 50/1.4 and 85/1.4 (even if 85 is very unique according to his dual-concave front element)...;)

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... ;)
---------- Post added 20-06-20 at 00:25 ----------
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... ;)

A 20 years old performer. Despite the fact that the HD Pentax-D FA★ 85mm f/1.4 SDM AW must be a gem, you should understand why I can't abandon it..

The best STAR D-FA Pentax lens built to date for all generations as of today? With its bi-concave front lens, this lens enters the very closed circle of lenses with exceptional formulas such as the Zeiss Otus at € 4,000. Except that it is autofocus and takes advantage of the ISIS / SR of Pentax DSLR OVF cameras. It is a monster in every sense of the term where priority is given to quality versus maneuverability, like many optics released in recent years. In fact, the lens is heavy, bulky, and its setting point is probably not as pleasant as with a Leica-R optic I own…
Whatever tests come, apart from lens centering defects, the probability that it will be exceptional leaves little room for doubt. Especially since the K-1, despite a 36Mp Sony sensor (derived from the Sony A7R) "dated" for several years, but in Pentax sauce, remains in my eyes the best of FF OVF / EVF format until day with interchangeable lenses…
Just for that, both for the qualities of the body and the lens combined, the couple deserves to be in the bag of any photographer who seeks perfection, whatever brand he is a fan of…
In truth, I don't see any FF system capable of competing when the needs are very specific with the Pentax K-1 / HD PENTAX-D FA★85mmF1.4ED SDM AW couple. They justify their purchase alone.
Bravo Pentax!:)

I am not sure your protocole can be validated. I think your scene is subject to motion blur. I can confirm the Leica Summicron-R 35/2 is the weakest lens of my Leica-R collection but I still use it, I love it. And I can confirm that the last version of Leica Vario-Elmar 35-70/4 (with asph element) is a very good lens indeed. Of the last rendering generation (Leica Apo-Summicron-R Asph 90/2, Leica Apo-Summicron-R 180/2, Leica Apo-Elmarit-R 180/28, Leica Elmarit-R 28/2.8 E55...). C.A. is very well controlled by Leica, and was known for that! Just the distorsion can create some problems with Leica Vario-Elmar 35-70/4 ROM at 35mm... and vignetting at f:4. And very well-known as well for micro and macro-contrast with pop-ud "3D" rendering...;)

No, I use my original modified enlarger where I fixed my Pentax K-1 (II) with Pentax Macro 50/2.8 on and shoot the negatve frame by frame. Enlarger's light source head is on the baseboard and the light is facing upwards to the negative through the diffusor. The camera is at the top of the system (replacing the inital enlarger head). The negative is placed of course between the light and the Pentax K-1 (Macro 50/2.8). The enlarger lens has been taken off. I focus thanks to the screen of the camera.
No it doesn't.;)

Absolutely no one knows what are the key features about this camera and you (the Pentax community) speculate about the price! :confused:
