A selfie in the garden I'm afraid: I stuck at home ill with a chest infection while my wife (and dogs!) are in the city this week, so no-one to use a people centred lens on!
But I really like the wide open look in some circs. It's certainly wilder than when stopped down just a little, and often that's bad, but in the right context it's really nice. It's sharp enough in the middle to be useful.
I'm going to be thinking about Biotars or Helios' if I don't watch out (actually maybe I have a Helios in the junk drawer which I used use as a loupe to examine negatives in the Old Days...)
Sun really brings out the sharpness on center. I'll get testing soon. Kind of jammed for time. That's a good thing, couple gigs this week. I think I had my dang EFSC on. I have like a mental block to turn that off. So now with adapter the TAP it's pretty easy to remember the setting f22 is 35/ f25 is 50 and f29 is 85

Thank you David. Always interesting to see how a fast lens performs wide open. Hope you feel better soon!

Just when I got used to the setting above, I've changed my adapter configurations to I don't have to rotate that dial so much.
I now have:
f/11 (15mm)
f/13 (35mm)
f/14 (50mm)
f/16 (90mm)

Would you guys recommend the Nokton 35/1.2?
The version II is better than the original. The lens is 'tank" heavy and may feel too front heavy for the camera. Expect images at f/1.2 to lose contrast and sharpness whereas the Nokton f/1.7 is very sharp in the center. Stopped down the 35/1.2 II will produce gorgeous images. The Nokton f/1.7 is also much lighter and more balanced on the camera. If I were to choose, I would go with the Nokton f/1.7 overall.

Okay after some testing and now I need to repeat everything but I was checking focus shifting as it does focus shift. But let me explain it because you would not normally work this way. If you focus at 1.5 than leave that focus as you stop down it does focus shift. But if you focus at working aperture it does not which makes perfect sense. I tried it because i read it was a big issue. So if you focus this lens do it at working aperture only not wide open and than stop down. Reason I am saying this as it seems a little soft so I need to check if my TAP is working on this or try a fixed adapter. I have some mixed results as i used the TAP on some series what I did was focus again at each aperture that I was working on and got the best results obviously as it is not focus shifting. I did get to a series where at 1.4 for the 85 and 1.5 on the Sonnar it matched pretty well but really I would say sharp more at F2 for the Sonnar so it could very well be my TAP but I'm not sure until I run it against a fixed adapter but my manual focus shots seem better than the TAP. But I don't want to blame anything here yet. I will go out and redo the whole test becuase I think I can get better results. the bokeh is awesome and all that but at F2 I would like to be pretty dang sharp its kind of 2.8 so something maybe off. Obviously I am being extremely critical here but I got some mixed results so need to go back and use the technique of refocusing for every aperture. Normally this is not a issue but when testing it can be. Normal your going to focus at F2.8 or any working aperture and works great there just don't focus wide open than close down
See I got a really nice result here at F1.7 with the TAP refocused at 1.7. BTW Bronco wall test failed but that was totally expected but F8 is not to bad. Lets say usable. Good new my GM 24-70 at 50mm and 5.6 is brilliant so that is the landscape 50mm.
Im more interested in the 85 1.4 GM being my sharp 50 when I need it. The Sonnar is the look lens or people.
Without doing anything it jumps pretty well. Also if you add clarity not here but does make it jump more
Another nice 1.7, I like the look and the sharpness looks pretty good here. I think If i want sharper and still stay at 1.7 I can actually push the sharpness more without getting overboard. This is just a base sharpening. One other thing with the TAP is Im still trying to figure what is more accurate AFS or AFC. Version 3 it was AFC but I'm not so sure right now. Im getting some slight hunting with AFC and that could be my mixed results.
Again don't panic I'm in testing phase on all components .
Guy - as far as focus shift - you're just manually doing what the camera does with native lenses (that everyone's been btching about) - but that's the reason i migrated from Nikon to Mirrorless - the Nikon 14-24 had massive focus shift but there was nothing you could do about it on a Nikon, at least it can be overcome on mirrorless. I don't mind how the Sony AF system handles it and would think the ability to overcome it with this lens is also a benefit.
Guy - as far as the sharpness - come on, you have to show us Big Bronco - we're big kids, we can handle it!
btw - to have expectations set properly, lenscore shows the C-Sonnar with a 695 resolving rating vs. 1037 for the 85GM. So, it's not expected to be 'sharp' but it would be interesting to see how that materializes with the Bronco to calibrate other results if nothing else.
Yea I want to shoot it again but with fixed adapter so that way I'm only working with one element the lens because it's not sharp until 2.8 on the wall. I should at least get F2 which still has great bokeh. But I don't want to post a mixed result either as that's misleading. I want make sure I nailed it all down. I'm picky as hell here and want to be comfortable with accuracy posting .
Yea I just wanted to see what the fuss was about why I tried it that way and testing its just easier but you do need to focus at working aperture. Which is going to be normally for us anyway in the field. My Nikon 14-24 lasted 3 weeks and it went back. Piece of crap with focus shift.

Today was a little confusing because I was trying to many techniques and the sun was playing cat and mouse with me. Now I know what this lens needs. I have a little time to decide if this is what I want. I like it so far just want to get it all down correctly
I'm really just looking for a baseline. What I'm shooting also is tough as nails on a lens. So I'm really just trying to get a feel for it. It's the least resolving lens I have too and I need to remember that. All my primes will kill just about anything

OK, folks (to use a Guy-ism) - i'm making the over / under at 5 weeks for the C-Sonnar in Guy's bag - any takers?
