I just managed to fine focus my Git2P (the 90deg)
The camera was focused in the center, but top-center and top-left of the image were soft.
Just to make it clear, we are speaking about pixel-peeping at 100% in full res photos.
It is possible that this would not be an issue in videos.
Well I do photos a lot and this irked me.
Today I managed to fix it partially.
I completely opened camera (see one of those disassembly videos).
Lens was not touched (not rotated as one does for typical focusing after e.g. lens replacement).
What I did is to tighten a bit one screw on the back of the sensor.
The back of the sensor has only 2 screws, one top and one bottom.
My reason was that top-center is soft, thus maybe I should tighten the bottom screw.
This was actually hard and I did apply quite some force to tighten it by about 45deg.
And it worked. Not perfectly, but it did improve the image.
Now the old question: do I open Git2P again and again risk it. Not sure...
This is not the first time I am doing this. I also did such fine focusing on my Xiaomi Yi (the original old camera: one of the best for photos if you ask me).
That time I made it more careful and in couple of trials.
And result was that one of the screws I did tighten by about 45deg
(I think there were 4 screws holding sensor for Xiaomi Yi, contrary to 2 screws holding lens base for Git2P).
The improvement was quite significant, but it looked kind of tread-off: the center was touch softened by making 2 edges sharper.
Thus this time with Git2P I just did 45deg tightening on one screw (think which one you need if you replicate this: the bottom or top!).
Anyway, maybe this helps somebody. If really needed I could add some documentation images I made.
My quest now is how to improve the look of the Git2P JPG images.
I don't have time to fiddle with RAW images at the moment so it has to be JPG.
I applied Git2P 90 firmware mod and it did improve details in JPG image:
Now, how do I get better colors and metering in photos? Any thought or your settings are appreciated.
