Front dial unable to control S.S. (X-T50)

[RickAsh]

Just got my new X-T50 and I'm experiencing this strange behavior where I'm unable to change the shutter speed with the front dial.

Just listing all the things I've already done/tried:
1. I've set SS as one of the options for the front dial
2. I've set the shutter dial to T
3. Rotating the back dial when shutter is in T mode DOES work
4. I have depressed the front dial until SS is the highlighted option
5. The front dial DOES work when used for other settings (to confirm it's not a hardware error)
6. Interestingly the little half circle in the UI that appears next to aperture, iso, SS etc to indicate what the current front dial selection is does NOT highlight shutter speed, even though shutter speed is selected in the pop up when you depress the front dial

I'm guessing this is a software/firmware bug? Unless there's some obscure user error I'm not fathoming.

Anyone else with an X-T50 that can confirm this? Or any other models? Curious if it's a general firmware bug or it only affects the X-T50.

Thanks!

When you press and hold the rear command dial to access it's assigned function, is it set to shutter speed? If so, try setting it to control another function. Then, see if you can use the front command dial for shutter speed.

Yes the bug still occurs regardless of the setting of the back dial.

I experienced the exact same thing with my X-t50. Could not change SS with front dial when in T setting. I have an XT-5 as well which works just fine.

I eventually managed to get it working and the half circle symbol did finally show up.

I *think* i disabled the SS function for front dial (the option below programming functionality of command dials) and then re-enabled a couple of times and somehow it started working. It did not work the first time i tried this I had to do it a couple of times.

I suspect it is a SW bug.

I have exactly the same problem. I have had two XT50's and they both had it.

There's no bug in the firmware. If you'd like assistance configuring your X-T50, please ask. Let us know which exposure mode the camera is in, how the top panel dials are set and how you've configured the command dials & function buttons through the menu.

Here's a link to the X-T50 manual: https://fujifilm-dsc.com/en/manual/x-t50/

 

[MSS997]

Here are my settings:

1. Shutter Speed Dial set to "T"
2. Front Command Dial settings options:

• "1": F
• "2": SS
• All other Front Command Dial setting options are set to "None"

Rear Command Dial setting option to "ISO"

The Front Command Dial defaults to "F" and works correctly to change aperture (my lens does not have an aperture ring). If I click on the Front Command Dial, the screen shows the highlighting moving from "F" to "SS" but the blue "half-circle" doesn't show and rotating the dial does not change the shutter speed. The half circle only shows up under the SS if "SS" is option 1. If I switch the options so "SS is on the Rear Command Dial, it also works fine. All other options for the Front Command Dial also work just fine. I have also "moved" the Front Command Dial options around to try SS in all positions (2-4) and it doesn't work anywhere else.

I have the latest firmware installed.

Since I shoot a lot in aperture priority, I prefer having aperture be option 1 (default) on the command dial. If Fuji only wants SS to work in option 1, that's fine I guess but then why show SS as an option for positions 2 - 4 if it doesn't work there?

BTW: This is the second XT-50 I have owned and they both have had the same issue.

My guess is that, since the lens has no aperture ring, the camera will keep the front command dial assigned to aperture as long as the lens is in manual aperture mode. If the camera allowed the front command dial to control shutter speed, you'd have no way of controlling aperture.

If you set the lens aperture to auto, does that free up the front command dial to control shutter speed? If so that would tend to confirm my suspicion that locking out the front command dial from controlling shutter speed when a lens with no aperture ring is mounted to the camera and set to manual f-stop is designed functionality.

I can't help other than to say this is exactly how my X-T50 behaves as well. I spent hours of trial and error when I first bought it, thinking I had missed some setting or other even though I'm not new to Fuji "T" cameras, but to no avail.

Like you I usually use aperture priority except in special circumstances where full manual is more appropriate, and fortunately the only time I need shutter speed on a command dial is for long exposures on a tripod and it isn't really much effort to just long-press the front dial and change a dial from ISO to SS during set-up. ISO is normally fixed during the session so I don't really need to change both SS and ISO, and the Q-menu covers ISO anyway if needed.

It's an odd sort of behaviour though and I have no idea whether (or why?) it's supposed to behave this way but I've accepted it as one of the camera's little quirks and don't agonise over it.

Bill: Two things about your latest reply

1) On the XT-50 the Front Command Dial has 4 positions (clicks) for options. So even if I did not have aperture in the first position, I still would have 3 other positions to put it in so I should not be forced to use any one position to control aperture. And in fact that is the case; I can set aperture from positions 1 - 4. And, as I said in my letter, you can put SS in position 1 and it works and I can still change aperture in position 2 - 4 so I don't think that the fact that my lens does not have an aperture ring has (or should have) any effect on which position the SS option is placed.

2) I tried what you suggested about switching aperture to auto and seeing if SS would work in another position besides 1. It still does not work.

I am writing these responses not to whine about it (well maybe just a little) but to prevent other XT-50 owners from spending (literally) hours trying to figure out what they were doing wrong or to prevent them from feeling like they are the only ones with this problem or stop them from feeling that they were going insane.

I also wanted it out there so that everyone knows its problem and hopefully Fuji will fix it.

Oh and by the way, I do like the camera in spite of this. Haven't had this much fun taking pictures in a long time.

It would be interesting if one or more X-T50 owners in the forum who have a lens with an aperture ring could check if shutter speed can be controlled using the front command dial when the camera is in manual or shutter priority exposure mode. Similarly, it would be interesting if one or more X-T50 owners who have a lens without an aperture ring could do the same and share their results.

The behaviour is consistent no matter which lens is used; any function that requires shutter adjustment via a command dial works only with the rear dial or the first position on the front dial. The alternative front dial settings for shutter speed never work when selected.

I've tested this with both XC and XF lenses with and without aperture rings in all modes including "P" (by configuring the lens "A" position to "Auto") and of course the usual "M" and "S" with the lens "A" set to "Command". All behave the same, with SS/P-shift available only on rear or first position front dials.

Hi,

I have a new XT50 since October 2, 2025 with latest firmware and I too have a Front Dial issue, even after trying every suggestion to be found on the web. I have only gotten the Front Dial to work for Film Simulation settings, not Aperture control or Shutter control. Some particulars:

I assigned Front Command 1 to "F" (aperture), 2 to SS, 3 to Film Simulation, 4 to none.

My lens is a new XF 16-50mm f2.8-4.8. It has an Aperture ring that can be set to A or Manual. According to Fuji's own website FAQ, if your camera has the option "Aperture Ring Setting (A)" you should set this to "Command". Others added that you also need to put the lens itself in "A" mode. This should make it possible to set the aperture with the Front Command dial. This did not work for me, nor did having the lens in M mode.

When I press the Front Command dial it does not cycle through the 1 to 3 button assignments. It just invokes the Film Simulation menu.

I set the Rear Command dial to manage ISO, and this works fine.

Any new ideas would be appreciated.

Follow up next day...

I got the Front Command dial to work this way-:
To use it to control Shutter Speed, I had to assign it to Front Command Dial 1. Doesn't seem to work in position 2. Then the SS top mode dial has to be either in "T" or on a specific SS speed. Not in "A".
The SS info is not shown in the bottom UI row of settings info if the SS mode dial is in "A".

So my Front Command Dial assignments are SS =1; F =2; Film Simulation = 3; None =4.

And I can see the upper half circle symbol representing the Front Dial cycle through the SS, F, and FM UI icons on the LCD screen.

And to repeat what I said before, the Lens with an aperture ring needs to be set to "A"; and in the Button/Dial Setting menu, the "Aperture Ring Setting (A)" setting has to set to "Command".

I am completely new to Fuji so I hope my "struggle" wasn't too tedious.
The info you all posted was helpful.

It may not be helpful, but I can confirm that these settings are working properly on my X-T5, with Fuji lenses with an aperture ring (I have the Xf 16-50 kit lens, set on "A"), and with my one lens without a ring (Sigma 10-18mm f2.8). I can also set the aperture function to slot 1 on the front dial, and shutter to slot 2, and they work accordingly. I also have ISO set to slot three, and when I short-press in the front dial all three show up as options. Then I just short-press once to change to the next function. A long-press will display the slot option setting menu.
Dial and ring setup:

- ISO dial to 'C" for Command.

- Shutter speed top dial to "T" for Time

- Aperture ring to "A" on lens

Setup Menus:

- Menus button > wrench/spanner icon > button dial setting > command dial setting > (select the slots), then Back


S.S. Operation for command dial > ON, then Back

Aperture Ring Setting (A) > Command. This greys out the next menu item for Aperture adjustment with lenses lacking a ring.

So again, with these settings the front dial is functioning as desired on the X-T5. When I read the X-T50 manual, it looks like all these menu options are there, so I don't know why it isn't working. The point of my post is to confirm that it is working as a set of features on the X-T5, so no reason why it shouldn't on the X-T50.
