The 46mm Neewer HD Variable ND Filter 46mm 3-7 Stopfrom Neeweris adjustable from 3 to 7 stops, with a rotating ring to reduce light intake and extend exposure time when shooting at slower shutter speeds and wider apertures. Perfect for capturing rivers, waterfalls, light trails, and other moving subjects with dynamic motion blur. The rotation range is limited to approximately 70°, and advanced cutting-edge technology lets you say goodbye to the X-cross mark on images and other common problems with variable ND filters for wide-angle and telephoto lenses. With 30 layers of nano coating, the minimum light reflection rate is less than 0.1%, which reduces glare and ghosting, and blocks UV rays from 300 to 380nm, while ensuring accurate color reproduction.

Q: 1. Does this include, or even support, the tripod "foot" (that comes with the $164 version, but not the $99 version)?

A: No.

Q: 2. Will other brand EF lenses with autofocus continue to work with this adapter?

A: All EF lenses with autofocus Will work same way as on an SLR. The adapter only compensates for the shorter flange distance of the mirrorless body. in addition the filter slot makes easy to use one drop-in filter for every lens no matter the size of the front lens thread.

Q: 3. Do they make something like this that doesn't change the lens mount? Basically RF to RF, but allows me to have VND behind lens

A: No, lens adapters are made to connect different mounts. Unfortunately there are no adapters to just enable back VND filters on your RF cameras with their native lenses. Other brands make snap ND filters for the Canon RF camera mount, however they are fixed stops.

Q: 4. Is there a non-variable ND filter option that can be dropped in? VND can cause some really weird looks across the frame and the more I use them, the more I dislike them.

A: You can use this polarizer in the adapter. https://www.bhphotovideo.com/c/product/1434114-REG/canon_3445c001_drop_in_circular_polarizer_filter.html This clear filter is used when there is no filter present to prevent dust getting into the camera. https://www.bhphotovideo.com/c/product/1434115-REG/canon_3444c001_drop_in_clear_filter_a.html

A: No there is no option for that.

Q: 6. how bad is the vignette for ultra wide angle lens i.e. 11-24mm, 16-35mm?

A: If it is lens that covers a Full Frame Sensor, such as the Canon EF 11-24mm f/4L USM Lens B&H # CA11244LUSM, there should not be any vignetting. https://bhpho.to/2bPYxeO
