That's better, I can see what you are talking about now!
There is a bit more chromatic aberration than I would like to see, but I think that is probably close to normal, most people use it for video so don't ever see the corners of the 4000x3000 pixel sensor. Looks a little out of focus to me, can't be camera shake since it appears to be on a tripod, and the blue is more out of focus than the red and green, if focus was adjusted a bit towards the blue then it may reduce the visible chromatic aberration a bit and it would look better. The Yi 4K was originally a lot worse than that but I think they changed to a new and much better lens when they released the 4K+, the 4K+ is much better.Hi!
I have a lot of chromatic abberation on the still images I take with the G3, a lot more than on a Yi 2K, 4K. I don't know if it's the case for all G3 or if mine is defective:
My comparison is not with the Yi 4K or Yi 4K+, but with the Yi 2K, the old and cheap one !The Yi 4K was originally a lot worse than that but I think they changed to a new and much better lens when they released the 4K+, the 4K+ is much better.
It is possible that they have improved the lens and the jpg is still correcting for the chromatic aberration in the old lens, maybe worth a PM to @gitup to get it checked by the developers.My comparison is not with the Yi 4K or Yi 4K+, but with the Yi 2K, the old and cheap one !
I did another test and noticed something strange:
There is much less chromatic abberations on a RAW image. And when I switch on the RVB layers it is ok with the raw, but the jpg's blue layer seems larger.
You can try by yourself: www.stemani.fr/public/raw_vs_jpg.zip
It seems like a bug in the internal G3 raw to jpg conversion.
I guess, it is caused mostly by software and its image processing settings and not so much by lens. Git3 original firmware has very high levels for Blue channel amplification, and in combination with some processing filters it may cause such "glowing" effect. I would suggest checking modded firmware, which uses different settings, to see if this issue still persists.There is much less chromatic abberations on a RAW image.
