I did a video test on an X-T1 to see which lenses could potentially work for video. I concluded that I'd really need a stabilized lens for a usable handheld result. Either that or use a tripod.
I don't care as much about stabilization for photography, but a stabilized version of the 16-55 f2.8 would be really great, perhaps almost essential, for handheld video.
That's where I currently see a hole in Fuji's lens line-up. Of course there's the stabilized 18-55, but when using a wide aperture it changes aperture when you zoom. Even though I'd personally never zoom while the video is recording, a constant aperture works much better for video imo. I guess I could use the 18-55 stuck on f4 as a workaround for now since video uses a slow shutter speed anyway. But that would take away in part the possible creative use of shallow depth of field. And it's not weather sealed. And, as I understand, the video has a slight crop, so the 16mm end of the 16-55 would be useful to have so I could go just a bit wider when needed.
