But at f/5, the DOF should be able to save the day... right?

Because I have been shooting MF for most of the time and this is my first fast normal prime with AF (the FA35 is intended to replace my Super-Takumar 35/2 for use on DSLR) so I left with the default setting of my K-S2 which worked rather well with my DA20-40: AF-A with auto 11 points. This setting seems to produce good results with my FA35 for stationary objects, but for moving objects it tends to produce acceptable but not nailed focus. I did not add any sharpening for #1. I used TAv for a 1/1000 shutter speed to be on the safe side and a f5 aperture which my experience from other MF lenses tells me to have a rather good DOF.
The FA35 was a recent purchase, and I shot the same scene with FA43 and Lens Turbo for the reason that I know this combo rather well, to serve as a backup for the FA35 that I am not familiar with.

I used TAv for a 1/1000 f5 combo, and shot raw which I ran through Affinity Photo. I left the in-camera WB to be CTE and did not add sharpening, but used rather aggressive NR as I did pull the shadow a lot.

Then I guess that's another topic related to the recent On1 and Affinity buzz. "Is there something that Adobe had done right that makes ditching Photoshop impossible?"

I did microadjust my FA35 and FA43. They are good at stationary subjects. However for moving subjects, they seem to have some hard time keeping up: I found AF-A and stopping down more reliable than AF-C, but I still get quite some of the images not nailing focus, but are still in a reasonable DOF for small enlargements.

I did find that I can't completely trust the SAFOX X autofocus system of my K-S2 when used with my film-era lenses (FA35/2, FA43Ltd). This was one of the images from that day which the camera did not nail focus but was good enough for it to be a keeper for documentary purpose or small enlargements. The NR I did on the image (as it was shot at ISO 1250) was slightly aggressive, which might worsened the softness. But the AF is a completely different topic. The two other images were taken with MF and prefocus, which I leveraged the red peaking and zooming of my NEX-6.
It was hard to find a opportunity to shot these scenes again as I was travelling there. However I did find my FA43 to be the better one in terms of CA of my FA lenses (FA35, FA43). The FA35 is definitely a big improvement over my Super-Takumar 35/2 in resolution, but it seems that CA control did not have that much improvement, especially in challenging scene where there are overhead wires against a clear blue sky.

The Adaptall-2 version? I do have a copy of that, nothing bad to say about it.

May I ask which lens did you use? It was not in the EXIF. FA77?

I have ditched Adobe CC so I no longer use Lr. I ran them through Affinity Photo's CA tool and defringe tool. There were some improvements, but not much. These photos were the result of Affinity's CA tool and defringe tool.

So I took my FA35/2 for some photo shoot the past weekend, and found some serious CA problems.
Here is an image shot with K-S2 and FA35/2
And here is another image in the same place with NEX-6, FA43 and Mitakon Lens Turbo II
However FA35/2 and Lens Turbo combo seems to perform better, here is a shot taken earlier with NEX-6, FA35/2, and Lens Turbo II
Is this normal for a FA35/2? I wounder because the user reviews seem to give this lens a rather high rating in terms of aberration control and sharpness.
