NEEWERMini Follow Focus with A/B Stops, Lens Sprocket, 15 mm Rod & Bar Clamp for Film Camera, DSLR/Mirrorless Camera, Compatible with Lens Diameter up to 114 mm

Don't know why I bought i guess follow for aggressive sale on advertising market, well quality good but honestly not use as I found its to difficult and uncomfortable, useless to me but you might like, I do without it better

Now my manual focus is just taken to another level. No more messing with the camera focus ring. I can hold my shouder rig and use this focus wheel with so much more ease its awesome.

I had been finding it frustrating trying to achieve quick focus transitions when filming tech workshops which involve repeated changes between human actions on computers and the resulting action of the device being controlled. Since getting this Follow Focus, it's been easy! 5 mins getting focussing spot on and locking the focus stops, before starting filming and that's it. The "feel" of the control wheel is just about right too when I need to do a temporary adjusment, not at one of the stops.I plan to try this with a couple of my other lenses for some outdoor scenes now.
