This 1- to 9-stop, Variable Fader ND2-ND400 Filter from K&F Concept is a 77mm filter providing an adjustable light reduction of 1 to 9 stops. It darkens the entire image evenly, allowing a photograph to be made with a wider aperture or slower shutter speed without overexposing your image. By slowing the exposure time or increasing the aperture, it is possible to control the depth of field and blur movement, creating a dynamic look for streams, waterfalls, landscapes, and more.

What size slip-on cap fits the 77mm size? Spec says front is 82mm; only push on is Kaiser 82 & people say it it's not a 82mm.
@Dan W: does the Sensei snap on require a thread to attach to? Because this variable ND has no externally facing thread, as far as I know. That is why other Q&As point to needing a slip-on cap.

Will my lens cap fit on this filter? The lens is a Lumix 12-35 micro 4/3.
The front thread for this K&F Concept Variable Fader ND2-ND400 Filter (58mm) would actually be 62mm, so your current cap will not fit.

Can you please confirm this will fit on the Tamron 17-28 f/2.8 Di III RXD lens. Will the 72mm front thread accept a 2nd filter?
The Tamron 17-28mm f/2.8 Di III RXD Lens for Sony E has 67mm front focus threads. As such, the K&F Concept Variable Fader ND2-ND400 Filter (67mm) would be compatible to fit the front filter threads on the Tamron 17-28mm lens. A 72mm filter would not directly fit on the front of the Tamron 17-28mm lens without the use of a step-up ring such as the Sensei 67-72mm Aluminum Step-Up Ring, B&H # SESUR6772.
