How does the variable neutral density filter work ...

How does the variable neutral density filter work with ultra wides like the 11-24mm or 16-35mm? Normally front mounted variable e neutral density filters aren't usable with such wide lenses but wondering if being mounted on the rear of the lens solves or improves these issues?
Asked by: Sean
This will adapt EOS lenses to R mount cameras , and the filter works good

Do this slightly change focal distance on lenses, or lose additional stops of light?
Asked by: Christian
The focal length will not change and you will not lose any light other than using the nd, which cuts out 1.5-9 stops of light.

Does this seriously not come with a cover for when the filter is not in place? That would be Canon's ultra-stingy style.
Asked by: Steve
It would be much smater to develop a variable drop-in variable ND filter starting at 0.0 optical density. (this Canon actually starts at 1.5). Then, the ND could stay put at all times without the need to buy a clear filter in separate. Now, if you want to save some $300+ dollars you can use the multi-shoot high dynamic range (HDR) method. As an alternative to split graduated neutral density filters, some digital cameras offer built-in HDR which allow the camera to capture and then combine different exposures of the same subject matter when shooting in RAW image format. However, as long as a sufficiently short exposure time is available, it is possible to exactly mimic the effect of a graduated neutral density filter by using two exposures of the same scene one or several stops apart and blending them with a graduated mask in an image editor. This method has the advantage that the shape of the mask can be freely defined in editing.

is there a clear filter?

is there a clear filter?
Asked by: walter
No, there is no a clear filter incorporated within this variable ND filter. You can get a separate clear filter and also a separate polarizing filter. It would have been nice to have a clear filter incorporated into the variable ND filter as well as in the polarizer, but such is not the case. To get clear, you must use the separate clear drop in filter.

I am more concerning the image quality and autofocus speed when using this variable ND filter. Does it degrade the image quality or add othe color tone(s) or hue(s) to the captured image? Does it slow down the autofocus speed at all?
Asked by: Rong
It works well , The darker the ND the slower the focus usually it gets , but in Mirrorless Digital Camera its not as bad , and it does not have a color shift

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.
Asked by: Steve
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
