I have the JJC and Smallrig, have to say Smallrig is much better than JJC (the grip is too thicker ), unless you prefer a hard metal grip. I think Fuji's and Smallrig are best options.
For smallrig plate, you may have to grate the edge where the bottom of your hand rest for it to feel like the camera body edge.
I have never noticed this effect on my x-t3, which I have owned for several years. I use Lightroom and recently X Transformer. I just thought to mention it as obviously it is not present in all x-t3s..
I have used my GFX 100S for stills for about one year, and everything is fine. Now I want to shoot videos as well. After watching tutorials on setting up the camera, I was ready to start shooting. Then the ridiculous issue raised: which button starts and stops the recording? I switched to video mode and pushed the trigger, but nothing happened. I also tried the other buttons, but nothing happened. Could someone tell me what to do? Do I need a special memory card?
