Best AUTOFOCUS setting for the Fuji X-T4 in VIDEO mode 

Thank you 🙏

Thank you

The eye autofocus of the X-T4 is great when it works, what’s missing is a smooth transition between the moments when the camera tracks the eye and the moment it loses the eye so switch to a different focus strategy 😉

So pay more? Great strategy...

Thank you 🙏 I was on Sensitivity +4 (don’t want focus to change every time I move my hand inside the AF box while talking), AF Speed -2 (targeting smoother rather than faster transitions).

Thank you

Well it's over now, isn't it?

I think a lot of people think that the AF range limiter setting is not available in video, because if you don’t know that you have to turn OFF the eye-detect AF the menu is greed out.

@@ddangelo42 a followup question: I tested the AF range limiter settings with my X-T4. WIth the 18-55 kit lens its seemed to work pretty well, but with my Sigma 18-35 with the Fringer adapter I was not able to set the range correctly. It looked like the actual range of the lens was about half of the settings in the camera. Have you tried theses range limiter settings with 3rd party lenses, native XF mount and other with adapter? Also, have you tried using the Multi option instead of Area?

I have not tried with adapted lens, but a lot of people are using them so your discovery is very important information! I have not tried the multi zone either, as by default I prefer to keep control of the focus area so did not think of it, but it’s a good idea to try indeed.

@@ddangelo42 I made a very preliminary test with the Multi mode and the 18-55 kit lens. And it seemed to work pretty well with the AF range limited from 30cm to about 1m. The camera focused on my face on the right hand side and when I showed a toy on the left hand side, the camera grabbed focus very nicely. And then back to my face when I removed the toy. I will run some more tests!

@@ddangelo42 Thanks for the video! This is how AF limiter works on my XT3. I set the range to, for instance, 1 to 1.5 m. So I point the camera to an object which is 1 m away and it is focused. But if I then point to the faraway background, it is not true that the focus stayed at 1 m. Instead, the camera tries to focus the background until it reaches the limit, 1.5 m. At this point, the object at 1 m is out of focus. So, even if it is better if the focus doesn’t go beyond 1.5 m, it is not the case that the focus doesn’t respond to faraway objects. If you want to follow someone walking and you set the AF limiter to 1.5-3 m, I think you can still have focus flickering. But I will have to try following someone with a gimbal, sometimes changing the distance from the person, and using AF limiter.

Technically you can, but I don’t think it will be useful in your case, as most of your focusing distances will be further from the camera, which is easier to track for the focusing system.

Hello, I could be wrong if there have been firmware updates since but I believe this feature is only available on the X-T4 and X-100V.

Balbo42 Thank you 🙏

Merci, tiens nous au courant des résultats !

My guess either manual focus or play with the AF speed/sensitivity. That helped me get more buttery smooth focusing transition.

I have. It tried with adapted lens. If the lens adapter does not receive/transmit the proper focusing distances, or with a crop factor, then it would makes sense to see this translate into the results. Might be too cumbersome in this case. I am using the highest tracking sensitivity setting and for AF speed I use -3 or -2 depending on the lens.

Balbo42 the 18-55 is the kit lens, not an adapted lens. I was quite surprised to see I had so much out of focus footage with the af range limit set.

Sorry, i thought I was replying to a different comment 😅 The 18-55 works well for me. Try widening a bit your range or increase your focus area to have some safety perhaps. Unfortunately I would need to be next to you to do real troubleshooting.

Balbo42 I appreciate the help and video. It was my first attempt so I’ll continue to test. When I was at a certain distance it seemed to work well so I guess it’s a matter of adjusting the limit. I’ll try again. Thanks again.

@@ddangelo42 I'm continuing to test the AF Range Limiter on my XT4 and even when I set a custom setting of 0.3 - 2.0 meters doing a vlog type talk the camera is still losing my face and grabbing focus on the wall behind me which is well beyond 2 m. It seems to be a straightforward setting but it always tries to focus well beyond my set range limit and the focus is terrible :(

Hi Hermès, thank you for your message and interest 🙏 I’ve recently changed my IG account handle to Geikotaku (to match its content) www.Instagram.com/geikotaku
