Hi, I'm a new owner of an X-T20.
Since I was a bbf user on my old canon setup, I immediately disabled AF on the shutter button and I'm using the AF-ON feature on the AF-L button of the Fujifilm.
I'm happy with these settings and it works as I want, but the issue I found is that the focus is not locked. After pressing bbf, taking several shots will shift the focus. It happens with AF-S, single focus point or area, and on P, A or S modes.
I'd like to know if you have the same behaviour on your camera, I can see it happening with both the 18-55 and the 55-200. To reproduce the problem just focus on a close subject, use aperture priority wide open to narrow DOF, focus with the bbf and then start half pressing the shutter button. The camera will auto set exposure each time, and by doing this you should notice the focus moving.
This is a typical situation when using bbf: you focus once and then take several shots for different compositions or exposures without touching the focus.
In the video at this link I'm reproducing the issue. https://photos.app.goo.gl/8iWxmakf7RWGRacg1
You can see I focus with the bbf and I take a picture perfectly sharp. Then I activate focus check and I start half pressing the shutter button several times. The focus slightly changes each time, and at the end I take a second picture out of focus. I hope you can see the difference in video.
What do you think? I'm missing some setting? Does your camera behaves the same?
Thanks
