This 1- to 9-stop, Variable Fader ND2-ND400 Filter from K&F Concept is a 72mm 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.

Would this fit or which will fit a Sony A7 IV 28-70mm Lens?
Absolutely, kinda. Your 28-70 has 55mm filter threads so you will need a 55 - 77 step up ring. thread the ring on the lens and then thread the 77mm filter on to that. Benefit of getting the 77mm now instead of the 58mm? When you move to brighter or longer lens with larger filter threads you only need a inexpensive step up ring to fit your comparatively more expensive filters.

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 ...
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.
