The 67mm M2 Magnetic Quick Swap ND Filter from Freewell offers 5-stops of light reduction with the convenience of their magnetic quick-swapping system. Once the magnetic frame is screwed onto the front of your lens, different filters can be attached, removed, or swapped out quickly and conveniently. The reduction in light offered by the ND filter makes it easier to use lower shutter speeds or higher apertures in brighter conditions while also preserving colors and detail.

The German optical glass construction and multilayer coating make the filter scratch and oil resistant as well as water- and dust-proof. The included filter pouch and lens cap help you further protect your filter when shooting on the go and switching between densities.

Q: 1. What's the widest focal length lens I can use with this matte box (on both FF and S35 sensor, using both stages of filters)? Will it work with a 10mm lens on S35 and/or a 14mm on FF?

A: The answer is...it depends. You notice focal lengths are not listed for matte boxes like this. That is because it depends on the sensor, the camera, the lens and the matte box what will precisely work. That being said, we would say that this matte box should have no problem with an 18mm on Super35 and 24mm on full frame. Depending on all above conditions, wider than those lengths may be possible. However, we would tend to think that the real answer for 10mm on Super35 and/or 14mm on full frame would either be a single filter clip-on matte box or a two filter 6.6 x 6.6 matte box.

Q: 2. Hello, I would like to know if a 2mm-thick filter is working with this mattebox ?

A: This matte box allows for the use of two 4x4" filters. It should accept any filter that is 4x4" in size.

Q: 3. This appears to be a 2-piece set. Is there a ring that screws into the filter threads of the lens, and the actual hood that locks on to the ring, boyonet-style? Thanks.

A: Yes there should be a rather heavy duty ring that screws into the filter threads on the lens and the filter will snap onto that ring. The best thing about this arrangement is that it is quick if you need to take it off occasionally. The downside is that it tends to move around in a circular direction while you're shooting and the longer part of the hood may get in the shot during wide shots.
