This Drop-In ND Filter for M10 Filter Holder from Haida provides a 7-stop exposure reduction across the entire image area, allowing a wider aperture or slower shutter speed than normally required to be used. Using a longer shutter speed makes it possible to increase blur to convey a sense of movement, or to dial in a video camera frame rate. Increased density also makes it possible to shoot using wider lens apertures, helping you to shoot with shallow depth of field.

This drop-in filter is made specifically to fit the Haida M10 Filter Holder System. It is constructed from optical glass for clarity and color fidelity, and does not affect the color of the image. To prevent internal ghosting and reflections, each glass surface includes 10-layers of anti-reflection multicoating. The additional nano coating provides an improved beading effect when the surface comes in contact with water or oil, allowing for easier cleaning.

This filter is designed specifically for photography applications. This filter is not suitable for direct solar viewing with the naked eye, including with optical viewfinders.

Related Questions and Answers

Q: 1. Will any 52mm screw in filter work with the holder or is it a specific filter? Can't find just the filter for the Canon 600mm III...it comes with the holder but no filter.

A: While you can use other 52mm screw-in filters, Canon Drop-In Screw Filter Holder 52 (WIII) with Protector Filter B&H # CA52WIIIF not just any 52mm filter will do. The actual width of the filter is the deciding factor measurement, not the filter thread. Unfortunately, filter manufacturers do not list that number. The best hint we have is the fact the Canon protective filter is 54mm wide and about 5mm high. At this time, reports suggest that the B+W 52mm filters fit. Here is one. B+W 52mm MRC 103M ND 0.9 Filter (3-Stop) B&H # BW103MC52 Good luck.

Q: 5. Will other 150mm CPL filters, like the one from Nisi and Benro, work on this?

A: The Haida M15 Filter Holder Kit for Sony 14mm Lens can use square polarizing filters like these, https://bhpho.to/3PDdfU8 . For a round one it only works with the one made by Haida.

Q: 6. 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: 7. How many stops of a ND filter is it?

A: Between 1.5 to 9 stops for the ND filter

Q: 8. Is there enough room for 4 filters and my Haida M10 holder system?

A: Yes it has room for up to six 100mm Filters and one holder.

A: This would work on the C70.

Q: 10. 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.
