May I ask how you set the electronic aperture on the new Pentax lens when you use it with your A7R?The new HD-Pentax-DFA 35mm F3.5 AL [IF] is very sharp, with just a little CA that cleans up well with the profile built into Lightroom. I'm shifting to the limits of the full image circle with an A7RII and it's great!
The original 35mm F3.5 is also special (sharper at working apertures than the 40/4 FLE but a tiny bit softer wide open). Both lenses are not designed for thick Sony coverglass while the new HD 35mm is.
Carl Zeiss Jena lenses for Pentagon Six are easily adapted to the Pentax 645. Adapters are available. I have most of them. The CZJ 180 is a fantastic lens. The 120 is also nice. I like the drawing of the 50. Just bought an 80 I did not try yet.I am speculating on different NOn Pentax Glass for the D. And Which adaptor will I need for these Hassy or Contax or ???

Would certainly agree with this post. A35 and A120 macro are superb lenses. 45-85 is good at low end particularly. The availability of great legacy glass is a huge asset. There are some clunkers though.All Hasselblad V lenses are very well adaptable on the 645 cameras. Never hear people rave on forums about these that they are so much better as the older Pentax lenses.
Sometimes about the 110/2 but from what I have seen I am not a big fan of its restless bokeh wide open.
If you're extremely critical buy the D-FA 28-45, D-FA 55 and D-FA 90. A differnt price range though.
It is not my experience at all that older Pentax lenses are mediocre. I regularly use the A 35, FA 45-85, D-FA 55, FA 75 and the A 150/3.5 All good lenses! I have more but don't use then that much.
May be the point is that people always refer to " wide open " results. It does not have my interest anymore, I shoot mostly between F 8 an F 13 and it that range these lenses give good results.
If I want to see something with any DOF on a photograph, wide open is useless. It is no problem at all to shoot ISO 800 with the Z. I don't know about the 645D
You can walk around for a long time with only the A35, D-FA 55, FA 75 and A 150. They are extremely small and light for MF lenses. They compensate nicely for the weight of the camera.
Pretty much agree, however that 25/4 that I had (and now discontinued for more than 2 years by now) could be difficult in the corners with the D some said so I personally have no idea how it might perform on the D. It was great on the Z, but probably sells for $3-4k now. Mine was the last copy for sale new in the world at about $5k when new.I think its based on individual experiences and personal choices, but for me the older Pentax lenses (which I bought a lot of) ranged from barely acceptable to pretty good. I did not find any of those lenses to be stellar. In my observation most of them needed to be stopped down to f11 to be worthwhile to me. In comparison, Zeiss lenses could be shot wide open. On a CCD camera like Pentax 645D that is a lot f-stops. Modern Pentax 645 lenses such as the 55mm, 25mm and 90mm are in a different league, both quality and price wise, when comapred to the older Pentax lenses. There also seems to be considerable sample variation in older Pentax 645 lenses. Thats also something to consider.
I also tried a Pentax 67 lens (cant remember exactly which one) and it was very underwhelming. Although the price was less than a $100 so no real disappointment there.
Thats just my 2 cents and YMMV.
Hi Marc, I'm not correcting distortion and have not found it objectionable. It is very mild moustache distortion typical of a retrofocus wide.May I ask how you set the electronic aperture on the new Pentax lens when you use it with your A7R?
And how you correct the files for distortion? I could not find a profile for distortion correction (not with the Alpa plugin, and I think Capture one does not have a profile too). Or is distortion of the simple barrel type?
