Lt. Data should the lever at a FZ1000 not quite fit on the paper = missing a tenth - with a little good will but also fits this zoom lever to the thickness of the pipe FZ1k. However: ... the rotating ring on the lens is only one electric. Steller - the setting is a little 'spongy' therefore - for the zoom lever can also nix.
Definitely 1000x better than this tiny zoom rocker on FZ1k housing!
Buy recommendation! (Pearl: MMN reputable provider, quickly accommodating)
