I am using an X-T1 for tethered, flash product photography. It is a chore to use this camera w/ system lenses at high stop down levels since the camera closes the aperture (while focusing) and the screen goes dark making it impossible to autofocus. With adopted manual lenses the day is saved. Fuji needs to ponder this problem and make a proper solution. Tried this with a more modern Fuji body the X-T30, but it does not tether, so I will have to sell it.
Hi Valantis, depending on the bitrate you are using I would suggest a V30 rated card which would be good for 200mbit/s. if you want to go all out at 400mbit/s you would need a V60 rated card. Thank you for the comment!
