Advanced Filters are selected (or deselected) using the Drive button

Have you tried repeating the firmware update via the card? I have no idea if it will work but might be worth a try.

Could you share an example? Preferably a link to an original image file - it could be a mark on the sensor. Is it always in the same place?

Its the same as other X series cameras in the Image Quality menu - two types: High ISO NR and Long Exposure NR

what exactly are you doing and what exact steps are you taking? when you say you "import to Lr or my phone" do you mean you are importing to LightRoom on your phone? what sort of phone and how are you importing the image files?

Press the Drive/Delete button on the back of the camera and select something other than BKT https://fujifilm-dsc.com/en/manual/x100vi/about_this_camera/parts/#drive_button

In order to use AF-ON/AF-C for back button focus you need to detach the focus action from the shutter button. In the menu here: https://fujifilm-dsc.com/en/manual/x-s20/menu_setup/button-dial_setting/#shutter_af Once the focus action is detached from the shutter button then AF-ON controls focus.

Are you sure? Does the main battery prevent the loss of settings if there is a defective capacitor and the camera is turned off?

There is an internal capacitor that supplies enough charge to keep the settings when you turn off the camera. It sounds as though this needs repairing. (I'm assuming you keep a fully charged battery in the camera? The capacitor can lose power if the camera is left for long periods without the main battery being charged)

I went through this same problem some years ago with the X-T2 and bought the first version of the Fringer adapter that jerryy has suggested. It has worked very well - and given decent AF performance as well as controlling the aperture.

Are you using custom settings perhaps?

The manual says it works the same as X series. "Each time the shutter is released, the camera takes one shot and processes it to create copies with different film simulation settings, chosen using A SHOOTING SETTING > FILM SIMULATION BKT."

That is the way its designed - if you want to access files on the camera card you will need to transfer them to a computer

I've found the FujiFilm service centre to be quite responsive with questions like this: https://repairs.fujifilm.eu/en/fujifilm-repair-centre/

Yes - I've had to fix apps I've written that worked OK with Sonoma but give obscure and undocumented error messages with Sequoia

Does the camera report the write errors? How do you know its the Delkin card that is the problem? Have you tried using the Delkin card on its own - do you still get errors? I have that exact same card and haven't had problems - but rarely shoot video. The only problem I've had thats remotely similar was with a particular combination of two cards in the two slots - either one was fine on its own - switching to a different card in slot 2 solved it.

Too late - I can live without X Raw Studio for a while - it makes you wonder how much testing Fujifilm carried out while Sequoia was in beta.

I have the same problem but only since upgrading to MacOS Sequoia - Fujifilm has a note on their website recommending not to upgrade to Sequoia with X Raw Studio.

Can you post an example? preferably an original file?

Does it playback in the camera? What happens if you try a test now - take a video clip and immediate try and play it back in the camera?

The only solution would be to change the profile to match the RAF settings - or just let the software make that change for you.

try putting the camera in shutter priority BEFORE connecting to XApp (or if you want to control both aperture and shutter speed put the camera in manual mode before connecting).

Are you looking for free software or paid for? You could try Apple's photos which comes for free with the Macbook - it handles JPG and RAF files (although not compressed RAF and Apple takes a while to support recent cameras). You could also try XnViewMP which is a free viewer/editor. If you are willing to pay for a subscription the Lightroom works well and will support all Fujifilm cameras and all file types.

I tend to use X Raw Studio mostly to experiment with different settings rather than create jpegs - its also useful for setting up and storing custom settings rather than using the fiddly camera menu system. As far as the 72 pixels per inch goes - I assume you are looking at the EXIF metadata - here is what Wikipedia says about those values "The XResolution and YResolution tags provide the number of pixels per length unit for the width and height of the image, respectively. (The length unit itself is specified by the tag ResolutionUnit.) By default, these tags in combination are set to 72 pixels per inch (ppi). These tags were inherited from the TIFF 6.0 standard and are required even though for images produced by digital cameras, image resolution values such as ppi are meaningless.

Do you mean "SD MEMORY FULL" with a brown zero at the top of the screen? If so then either: 1) you have deleted files from the card using a computer In this case just reformat the card and don't delete cards using a computer again 2) This is a bad card or a fake card with much less storage than it says on the label You could test it by putting into a card reader with a computer and see check the size (right click -> Get Info on a Mac) In this case copy off your images and get a new card
