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

      Display ISO will be chosen when auto iso is set

      By Cronin · Posted

      Found the simple answer to my own question. Having assigned Auto ISO to the rear dial, I only have to push in the dial to make the Auto ISO options appear, then turn the dial to choose. Nice and fast.

      Hello All, I am returning to photography after a decades-long hiatus that was prompted by my loss of access to a darkroom. Digital rendered that excuse moot, so I now return with a recently purchased XT5. I am from the Hudson River Valley in New York where I have spent the past five decades engaged in environmental work, mostly on the Hudson. I teach at Pace University where I direct the Gale Epstein Center for Technology, Policy and the Environment. My project ahead is documenting the unseen Hudson, a combination of the obscure, under-appreciated, and invisible - a street-style approach to people, places and things that make the river what it is. There will be little landscape, if any. The "Mighty Hudson" is well-documented. If nothing else, it will be a mission-driven project to bring me back to photography while learning my camera. I look forward to everything this amazing site can teach me. Cronin

      Fuji X-T4 AF-S and-C

      By IMX · Posted

      Hi,   I would really appreciate if someone could answer this question. Is it possible to have the X-T4 shoot in AF-S for photo mode and AF-C in video mode while the front lever is left at AF-S?  If so, how would this be done or wher in the menu system would I set this up? This is similare to setting the apeture at f/2.8 for photo mode but fioming at f/4 in video which I already have setup. Thanks and kind regards

      According to the manual you can assign auto ISO to any one of the function buttons but I've never tried it. (It's not something I frequently change so all my function buttons do other things.)

      By Cronin · Posted

      Hello, I have a new xt5 and have enjoyed its setup, until now. I hope someone with patience can help me through my ISO dilemma. My question: I have assigned settings for Auto ISO 1,2 and 3.  Should I be able to select Auto ISO 1, 2, or 3 for a shot? If so, how?  Or is the camera supposed to. At present, my screen shows Auto ISO 3, and never changes. I assigned ISO to the rear dial to no effect. Of course, when I half depress the shutter button is see the actual ISO in real time, but the function of the Auto ISO and how to control it has me confused. Thanks for any help.
