I'm also interested - I found some for Nikon DSLRs on ebay and Amazon but not sure if they will fit the XT3.

I don’t think anyone is making you use Facebook on this forum - I don’t and seem to be able to read and post without problem

On playback my X-T3 does show the elapsed clip time. (While recording I'm afraid you are probably stuck with mental arithmetic)

Set aperture on lens to A and make sure Aperture Ring Setting in the Button / Dial menu is set to Command

What is your AF+MF setting (under the AF menu)?

I assume you already have the answer to this - you seem to be using a different ViewMode on the X-T3. If you set ViewMode to EyeSensor then you get image review on either EVF or LCD depending on whether you have the camera up to your eye. If that isn't exactly what you want then cycle through the ViewMode options until you find one that meets your needs using the little button next to the EVF housing.

Drive dial only

If you are having trouble reading or finding the serial number its written into the EXIF metadata of every image taken with that lens

You're going to need some intelligence at the storage end - when you plug the camera into the computer its the Fuji app or something else that pulls images to the computer.

The usual arguments against these cards are that they can move around inside the adapter and give errors and they are so small that they are easy to lose. They seem roughly comparable in write speed with the popular SanDisk cards. If you want to save money they may be worth a try. Let us know how you get on.

I'd be interested if those Lexar cards have solved the problem - they shouldn't - they are maybe slower than the Sandisk 95MB/sec

You don't specify which camera and which settings you are using however this sounds like some other problem rather than card speed - a continuous burst will fill the buffer before it throttles because of card write speed and that should be more that 2 or 3 shots. The X-PRO2 supports UHS-II so you could try one of the recommended faster UHS-II cards such as the SanDisk Extreme Pro 300MB/sec or the Sony G series - faster for bursts but only once the buffer has filled.

No - I haven't seen this - but its always worth backing up your settings just in case

Cards are cheap enough to get rid of something that you know gives problems (or send it back if its a new card). Its rare to find problems reported with SanDisk Extreme Pro cards bought from a reliable source.
