The 82mm Freewell M2 Magnetic ND Filter 82mm 3-Stopfrom Freewell M2 Magnetic ND Filter 82mm 3-Stopoffers 3-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: 3. If using only legacy lenses, a mount adapter would always be needed, but not the ND filter. If shooting when the filter is not needed, would I have to purchase the basic mount adapter, or can I just remove the filter from the adapter?

A: Yes, that is correct. SOMETHING has to be in the filter slot 1) in order to simply keep dust and debris out of the adapter (without the ND filter or the clear filter, there would be a large opening in your adapter on which your lens connects), and 2) as the adapter was designed with the ND filter in mind, the filter becomes part of the optical formula. Without a piece of glass with the same design and size in the slot, it may affect proper focusing. As such, the Canon Drop-In Clear Filter A, B&H # CADICFA, is required when you are not using the ND filter and you do not want the effect of an ND filter on your image.
