Manual focus during video recording not working

I have just upgraded my firmware to 1.70 and now my manual focus during video recording has stopped. 
 

Manuel focus works fine to set up your focus but once you hit the record button, manual focus stays in the same position and the wire focus does not work.

 

I have tried this with three different lenses all with the same problem

Hi, I just started to use my video features on my XT3/4 (after years of just Photo shooting) and have discovered the same issue. I upgraded to the lastest firmware recently.

The 23mm f1.4 clutch lens DOES video MF in M mode..... UNTIL YOU HIT REC VIDEO. Then the MF ring doesn't do anything at all. BUT that same situation WORKS fine, on other non-clutch lenses (tested with 35f2, 18-55f2.8, 50-140f2.8, 56 f1.2)

Do you recall this happening only AFTER upgrading to the last firmware? If so, WE NEED TO MAKE FUJI KNOW, TO FIX IT ASAP!! This is very shameful FUJI!

 

I found a workaround. It's VERY clumsy but for now does the trick, WITH STRONG LIMITATIONS:

1) In M mode, with the clutch activated on the 23mm f1.4 lens, MF your scene.

2) Then Switch to S mode, making sure the FOCUS SQUARE IS AT THE SAME PLACE OF YOUR FOCUS INTEREST.

DONT SKIP THIS, otherwise the focus by wire will move the focus point (focus at other distance) the MOMENT YOU HIT REC, and then the LENS CLUTCH focus MARK and the CAMERA focus MARK WON'T MATCH, thus making IMPOSSIBLE to MF, as the THROW lenght AVAILABLE on the LENS CLUTCH won't be enough, so you cannot REACH EITHER THE CLOSEST OR LONGEST FOCUS POINT!! This happens because Clutch lenses have hard stops when MF.

3) Press Recording, and IMMEDIATLY TURN THE MF RING, VERY VERY SLIGHTLY, so to DISABLE AF, and therefore avoid the camera to move the focus point somewhere else. This is because despite being in S (rather than C) mode, the AF point KEEPS updating!!! ANOTHER BROKEN THING !!

4) This workaround will work ONLY if the camera Video settings for AF+MF is set to ON

5) With all the above, DONT MOVE THE FOCUS RING TOO FAST!!! Otherwise the lens-and-camera focus marks won't match again (looks like it loses the LINEAR FOCUS mode), and you won't be able to focus to infinity or closest, while REC video.

 

THIS IS A TOTAL MESS!!!!!!!. My workaround is a PITA, but at least it works, if you do it very very carefully!

BUT WE NEED TO MAKE FUJI FIX THIS. IT RENDERS CLUTCH LENSES TOTALLY USELESS FOR VIDEO!! HOW CAN WE SEND A PETITON TO FIX IT RIGHT NOW?

(I'M VERY DISSAPOINTED WITH FUJI after this! Hello Sony? Means no AF issues, Magic eyeAF, Insane Continus AF for photo/video, ISO 1million, etc, etc)

Hi, The same problem here, with my XT4 (Firmware 1.7)

I contacted Fuji Germany and they said i should send them the camera. I told them that there are several customers complaining about that issue but they didnt respond to that.

Today i went to buy a used model in my town and to my surprise this Model (firmware 1.6) had that same issue!

Are there People having Problems even with that later Firmware Version?

I keep you informed if there are any news.

Regards,

Manuel

Yes, same issue here. XT-3 + 23 1.4 with latest firmware... This absolutely ridiculous - the camera plus the lens are around 2000€ but they don't work together in video mode. Other lenses work fine, just the clutch ones don't. Is this supposed to be a professional product?

Hello again. As far as I know, no new firmware has been issued to fix this UNACCEPTABLE PROBLEM.

The camera and lenses were sold advertising certain amount of features. Now, those things belong to FALSE ADVERTISING.

IM VERY VERY UPSET. I VOTE FOR A LAWSUIT AGAINST FUJI, THEY HAVE MADE THIS MESS AND ARE NOT FIXING IT!

It seems like using an external recorder is a good workaround for this problem. 

I just press record on my Blackmagic view assist - without starting to record on the camera itself. That way I can still focus.

Works until they release a Bugfix I guess

Hey guys,

Just want to let you know that we wrote to several Fujifilm repair centers, and I just seen they release v1.72 firmware to remove flaw caused all clutch lenses not being able to manual focus while recording. (23mm 1.4, 16mm 1.4, 14mm 2.8)

Give it a try...

Regards

      Looking for Full Frame lenses to adapt to GFX

      By Giampaolo Masserano · Posted

      I use a TECHART ring to mount Canon EF lenses on the GFX 50S-II and 100S-II, maintaining image stabilization and autofocus. The only limitation are lenses with a small rear element diameter that make it impossible to cover medium format. Fast lenses like the EF 85/1.2L or the 100-400L, however, work great.

      Looking for Full Frame lenses to adapt to GFX

      I also use a Nikon to GFX Fringer and it works very well.  24mm f/1.8 vignettes so best used on 35mm mode.  50mm f/1.8 covers the entire frame very well with no issues and is a superb little lens. 105mm Sigma vignettes slightly but is perfectly usable. 300 f/4 likewise the 105.  I have a 70-200 f/20+.8 incoming to test so will report back but I'm expecting a little vignetting.  Even in 35mm mode the image is still 60MP and if you're prepared to manually crop and correct you can get 80-90 MP images.  I also have a C/Y to GFX adapter.  The 24mm Sigma Superwide vignettes strongly. Ditto 28-80 Zeiss Sonnar. 80-200 f/4 Sonnar is perfectly usable. All work fine as 35mm mode lenses.  I also have an M42 adapter which I tried with the Carl Zeiss Jena 135mm f/3.5 with good results.

      Image correction with GF20-35

      Image correction with GF20-35

      By jerryy · Posted

      Ahh, the infamous brick wall photos… 😀 According to internet lore, if the dng converter does not properly apply the corrections, you can have it apply custom profiles that should work for you. How to do that is waaaaaay outside of this comment’s scope, but there are plenty of sites listed in the search engines that step you through the processes. Best wishes.

      Image correction with GF20-35

      By Trevor R · Posted

      Jerry Thank you very much. That is extremely helpful. It seems that the camera and the lens have the latest firmware update, so it appears that the corrections should be applied automatically. The lens arrived this afternoon and I took some quick test shots, in which the correct lens information appeared in the EXIF files, so that sounds good. I used Adobe DNG converter to convert the Raw (RAF) files, and then opened the DNG files and saved them in PSD format. However, with a beautiful, clear, cloudless blue sky, there were no lines near the edges to check if distortion had been corrected. Another day I plan to photograph a brick wall. Thank you for your help.
