The 4 x 4" Cavision Enhanced Range ND Filter has a filter factor of 8x that provides a 4-stop exposure reduction and is compatible with filter holders that can accommodate 3mm thick rectangular filters. Its 1.2 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By increasing your aperture or slowing your exposure time, you can control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

This filter is uncoated and is constructed from optical glass for clarity as well as color fidelity. Its enhanced range design is intended to maintain image sharpness when used with lenses that feature a focal length of up to 300mm.

Q: 2. Is this filter stackable? And what does the 103M mean in the name?

A: Dear Sara, the filter is stackable. The front end is threaded and can accept another filter (or a snap-in cap). 103 (ND.9) means 3 stops compensation, just as 101 (ND.3) means 1 stop and 102 (ND.6) means 2 stops compensation.

Q: 3. It says "Series 8", so is it compatible with Hasselblad SWC's Biogon C 38mm lens?

A: The Hasselblad SWC's Biogon C 38mm lens uses a series 60 mount, not the Series 8 mount. The B+W Series 8 MRC 102M ND 0.6 Filter will not fit the Hasselblad 38mm SWC lens.

Q: 5. How does this attach to the phone? I have a clip on ND I'm not happy with since it has light leaking in.

A: The Kase ND64 6-Stop ND Filter for Smartphones BH #KA1117130001 would come with a stick on L-Shaped Magnetic Adapter that is semi-permanent adhesive.

Q: 6. What's the weight of the filter Could it be used instead of the balancing ring needed for the X5S?(drone proposes).

A: Unfortunately we cannot weight any products here and the manufacturers do not provide the weight of lens filters. It may be best to ask your question on the drone Q&A itself, but we would guess that it is the same weight and could be used as a balancing ring if necessary--though it is not an exact measurement.

Q: 7. Will I get vignetting with this filter on a Zeiss 21mm/2.8 ZE lens? Thanks!

A: That lens is just on a full frame camera might give you a tiny bit of vignette. It is on the very edge.I would suggest getting one that is for wide lenses like this,B+W 82mm #102 Neutral Density (ND) 0.6 Multi-Coated (MC) Extra Wide Glass FilterB&H # BW102MC82EW Mfr # 66-1070601http://bhpho.to/1oDK7Mh

Q: 10. How much does the filter weigh?

A: I don't have the means to weigh the filter directly. I does not weigh more than any other of the B&W filters in this particular mount. You can go to the manufacturer website for this exact product and ask the weight question. B&W Photo does not permit inserting outside links, so do a Google Search on Schneider Optics, once on the website, copy and paste the manufacturer's part number that B&H Photo includes, that will give you the specifics on this product. Then you will have links to ask the weight question of an associate. I hope this helps.
