This 6.6 x 6.6" Tiffen 3-Stop ND Filter 6.6 x 6.6"is a solid neutral density filter providing a 3-stop exposure reduction. This 0.9 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 are able to 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 made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 6.6 x 6.6" / 167.6 x 167.6mm.

Q: 1. Is this filter compatible with the Moment M-series lens - 67mm filter adapter?

A: No, the Tiffen 62mm Variable Neutral Density Filter is not the correct size for the Moment M-Series Lens 67mm Filter Mount. One would need to get the Tiffen 67mm Variable Neutral Density Filter, BH #TIVND67 (https://bhpho.to/3FUZ4GR).

Q: 2. 72mm is my biggest lense thread so Ill buy 72mm , but I also have a 55mm lense and 67mm lense which i would use step up rings. How will this variable ND filter fare with the smaller lenses? Will i get bad vigneting or anything else?

A: I've used it on smaller lenses, it works great for me.

Q: 3. Does anyone else get a grinding noise/feeling like a tiny piece of sand or metal in in between the gliding rings? Should I take it back and exchange it? Haven't had it for more than a day. Also seems like the oil in between the rings comes out rather easily. Functions fine, but if it's defective I want a normal one.

A: The VND filters should not grind and oil should not leak, this is the first time I have heard of these problems with a VND. Our apologies, but it sounds like your filter is defective. You can do a return through B&H or directly with Tiffen, your choice. If you choose to return through Tiffen please send the following information to techsupport@a href= http://tiffen.com; target= _blank tiffen.com;/a your name, shipping address and phone #, a copy of your B&H receipt, a description of the problem and please request a Return Authorization (RA) to have this item replaced under warranty.

Q: 4. Most solar filters I've seen are rated at 16.5 stops. Why is this filter rated at 18 stops?

A: The solar filter minimum recommended is 16 stops, however it is not limited to be only at 16 or 16.5 stops.

Q: 5. I have a Sony Zeiss Vario-Tessar T* FE 16-35mm F4 ZA OSS lens. The filter diameter is 72mm. What size do I need to fit this ND FIlter? If I choose 72mm, won't vignetting occur at 16mm? I've heard this filter is thick.

A: You will need to get a thin 72mm filter, I would recommend the Cokin nd, click the link below to view; https://www.bhphotovideo.com/c/product/1487120-REG/cokin_cnv2_72_nuances_variable_nd_2_400.html

Q: 6. What's the pitch of the threads?

A: Not sure about "thread pitch" however, I can say that is threads on & off my Canon RF 24-70mm f/2.8L IS USM Lens just fine.

Q: 7. will this fit on a Canon XA25 & does it eliminate the subject washout I get from bright/white stage lights?

A: This filter will fit any lens which has a 58mm filter thread. The Tiffen Variable Neutral Density Filter provides two to 8 stops of light control. This means that it limits the amount of light entering your lens. By limiting the amount of light entering your lens you achieve greater control over your camera. You can do long exposures with the VND (blur moving water, clouds, etc) or use it to control your depth of field in bright sun.

Q: 8. What’s the diameter of this filter “wheel”?

A: Tiffen does not manufacture the filter wheel, we manufacture the filter which fits into it. You would have to contact the camera manufacturer for detailed information on the filter wheel.

Q: 9. Hello, I am new and wondering, does anyone know if this will fit this lens? https://www.bhphotovideo.com/c/product/1369132-REG/sigma_402965_16mm_f_1_4_dc_dn.html

A: Yes it will.

Q: 10. which clip-on mattebox works with this filter?

A: A rotating filter, like the Tiffen 82mm Variable Neutral Density Filter, is not compatible with clip-on matte boxes.
