ISO not displayed on LCD/viewfinder for shutter half press using AF-C on X100F

[Shane-M-J]

Hi all
I have an X100F and use AutoISO which works but does not display the actual ISO on half press of the shutter in AF-C but does in AF-S. It's driving me nuts and I've been through the menus so many times and have reset too but can't get it to work. Any ideas please?

That’s because in AFS you’re locking both focus and exposure but AFC the focus and exposure are constantly changing .

SHUTTER AE must be enabled for AF-C as well as for AF-S

But on a Facebook group a chap posted a video of his X100F set in AF-C with the shutter half pressed and the true ISO shown which varied as his exposure changed.

Hi Erik, can you point me to where that is in the menus please? I am on Firmware 2.11

MENU > WRENCH > BUTTON AND DIAL SETTINGS > SHUTTER AE > AF-C > ON

 

[Shane-M-J]

I don't have that menu option. X100F with Firmware 2.11

The menu settings are different on X100V. There is no Shutter AE on the X100F. Check the manual.

Thanks, I had guessed I was getting replies from those with X100V. Can't find any mention of it in the manual. It's just odd that the actual ISO is displayed when half pressing the shutter when AF-S or M is selected but not when AF-C is selected. Some have said they do get the actual ISO displayed when they half press in AF-C even but I suspect that they are using a X100V too.

If you think you are having an issue call Fujifilm support. If in the USA the number in Edison NJ is:

1-800-800-3854

PRESS OPTION #2
ON MAIN MENU

They are very friendly and helpful...

You guessed correctly, here are the Button Dial settings for the X100V and F:

Sorry, my bad. I thought the F shared the same badic menu options as the same generation X-T2 and X-T20. Strange though, I’ve used an F and didn’t notice any major operational differences - might be because I almost never use AF-C.

Anyway, no Fuji camera that I’m aware of will display the shooting ISO without a fixed or locked exposure value (which you typically get with a half-press of the shutter button). Pressing the AEL button will accomplish the same thing (exposure compensation will still be active, but you will no longer be able to move the AF box around).

With cameras that allow setting whether a half-press locks exposure separately for AF-S and AF-C, many people want it off for AF-C anyway so the camera can continuously adapt exposure as the light changes.

Thanks for that, very helpful. I did contact Fuji today in the UK. Their tech support line answered very promptly and listened. I explained and their X100F behaved the same as mine. They could not explain it and said they would do some research and get back to me. They've not come back yet but I now expect that the camera does not have this capability and it is corrected in the X100V.

 

[Shane-M-J]

Thanks. If you see my reply above to another contributor you'll see that it is probably the case that the camera does not have this function and that it has been corrected in the X100V. I contacted Fuji Tech Support and they could not explain it. With Nikon, my main brand, I can set up Auto ISO, use AF-C, back button focus and the actual ISO is displayed in the viewfinder as you look live, constantly changing to the exposure 'seen'. I shoot wildlife a lot with Nikon and use Auto ISO religiously with everything else manual. It's nice, despite allowing the camera to select ISO, to see what it is doing. The only way I can do this with the Fuji on Auto ISO and AF-C is to review what I have just taken after the event in playback. At least I know now which stops my endless searching the menus and manual.

Are you shooting RAW? If you’re going manual with both aperture and SS and want the ISO displayed in real-time, why not just set the ISO manually as well?

Personally, I generally much prefer letting Auto-ISO handle the SS with a preset minimum, and fine-tuning exposure/lightness with Exposure Compensation on the front dial. This works great for almost anything if the 1/500” maximum (min. SS preset limit) isn’t a problem.

Also, you might want to experiment with AF-S single point rather than AF-C and BBF for best results in most situations. I come from Nikon as well, and what works with a Nikon doesn’t always translate well to Fuji. I never managed especially reliable AF results with BBF on Fuji (except in M mode), and get MUCH better results with AF-S/single point and full-press of the shutter button most of the time (including with single shot moving subjects). YMMV.

 

[Shane-M-J]

Yes I shoot RAW. I shoot AF-C and prefer to let ISO drift with an upper limit as I use it for street use and things are generally moving, as am I quite often. I like to set the shutter based on what I am expecting to shoot and will go as high as I can for the light and then adjust the aperture also based on the available light - DOF is not normally an issue with such a wide angle lens. Once I am in that range I then let ISO wander with an upper limit of 3200. I'll shoot a burst and the AF-C will take care of any movement. It works for me and I can operate with just one hand without having to mess about with settings at all. If light decreases I'll drop SS or aperture or both knowing ISO will run higher. I don't like using the BBF on the Fuji as ergonomically it doesn't work for me but it is all I use on my Nikon bodies. Overall it's a great camera but has a couple of niggles. Another is that if I select Focus Frame in custom screen settings, it will display in AF-C but not in AF-S - it just disappears which I don't understand as the LCD section modes should be global across the AF modes.

I shoot RAF on my X100V in ISOmatic mode (SS and Aperture fixed) with ISO auto and then run my keepers through DxO PhotoLab 7 Deep Prime XD for any required noise reduction.

Never really worry about ISO anymore.
