The Black Mist 1/4 with ND2-ND32 (1-5 Stop) Variable ND Filter from K&F Concept combines a variable neutral density filter with a 1/4 black mist filter to create single convenient cinematic style filter. It can not only control the amount of light entering the lens, but also adds a soft, cinematic dream effect for photos and video. The filter density is easily changed using the quick adjustment lever, and the advanced design prevents the "X" pattern found on lower-quality filters from appearing on the image.

This optical glass filter features a 28-layer nano-coating to reduce potential flare and glare, and for optimal resolution and color transmission. It also provides a resistance coating that repels oil and water, plus minor scratches and abrasions, making suitable for use on location even in harsh environments. The durable aluminum-magnesium alloy filter ring fits lenses with 67mm filter threads.

Q: 7. Can it be used together with other adapters for EF to GFX?

A: Yes, mounting is possible when using more than one adapter. However, from our tests, the results have been wildly variable - from inoperability to semi-operability based on the make of the adapter, the firmware versions employed by lens, camera, and adapter, etc. As such, we cannot fully endorse such a combination.

Q: 8. If I use this on a full frame camera will it change the crop factor?

A: No. This adapter does not change the crop factor.

Q: 9. 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
