I shoot Fuji and have always used an add-on L-grip with my X-T bodies. The Zf body is very similar in design to the X-T. I was introduced to SmallRig when I upgraded to the X-T5 as a lower cost alternative to the OEM grip. I could not be more pleased with the quality, design etc of the SmallRig solution. Since I ordered directly from SmallRig, I am on their list for product announcements. They have announced both L and Cage grips for the Zf. More info here and the images below.
