The 77mm Cokin NUANCES Variable ND Filter 77mm 5-10 Stopfrom Cokin NUANCES Variable ND Filter 77mm 5-10 Stopis designed to mount onto lenses with 77mm front filter threads and provides an exposure reduction of 5 to 10 stops. Its density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the front filter ring, helping you to predetermine the additional exposure length required. By increasing your aperture or slowing your exposure time, you are able to control depth of field and convey movement more easily. For easier, repeatable control over density settings, the front ring is visually demarcated with dots and includes a rotation lever to further enable fast and precise positioning of the front ring.

This filter is constructed from Schott B270 glass for increased optical clarity as well as color fidelity, and each glass surface features 16 layers of Cokin's EVERCLEAR 5 anti-reflection coating. These coatings are resistant to oil, dust, dirt, and scratches, offering greater protection to the filter and helping it to stay clean for longer than with uncoated filters. The coatings are also hydrophobic, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.

Q: 1. Apart from the lack of the self-locking mechanism, are there other disadvantages of this model comparing to the self-locking one?

A: Aside from the density range and the locking feature, there is no other difference.

Q: 2. Are there front threads on this filter for use with a lens hood? Also, does it work as a screw in filter on the SmallRig mini matte box? If so, are adapters needed?

A: Yes. The following filter does offer front end threads.

Q: 4. Can i use this nd filter with ir cut filters? Any negative?

A: Yes, one can use them together. One may have a slight barely noticeable color shift.

Q: 5. Does this have a hard stop on it or does it rotate a full 360+?

A: The stops are indicated on the filter, however there is no pushback or hard stop as you rotate the ring.

Q: 6. What can I use as a front cap for this item (dont tell me Schneider 86mm Push-On Cap because it does NOT fit)?

Q: 7. Does this produce an X-Pattern at max ND?

A: It does at just beyond max, I just back it off a tiny bit and it's fine. The ND range is large enough that if you need to go beyond max, it's a sign that adjusting the ISO a touch might be a good idea.

Q: 8. Which stack caps or covers fit this filter for protection when not in use?

A: There are several caps for the SmallRig 77mm MRC Variable ND Filter on the product page, under the "Accessories" tab: https://www.bhphotovideo.com/c/product/1681507-REG/smallrig_3590_77mm_mrc_variable_nd.html/accessories
