The Tiffen 95mm Double Fog 2 Filtersimulates the effects of natural fog or mist by creating a soft glow around highlights and lowering the overall contrast of the scene. When compared to the standard Fog filter, this filter places greater emphasis on lowering the contrast while maintaining sharpness and minimizing the effects of flare. The 2 density provides a moderate amount of fog effect and requires no exposure compensation.

Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

Q: 1. 1. The description doesn't tell if there is a filter thread. My question is, can I stack another 77mm ND filter on top of this filter to further increase perhaps 3 stops ND effect?2. I was wondering if I use a step up ring, will vignetting disappear? Say if my lens has filter size of 67mm, and I use a step up ring to put on this 77mm ND filter. Since the filter is larger, will be reduce or able to even avoid vignetting issue for wide angle lens such as 12mm etc.? Thank you!

A: There are no front filter threads on the Tiffen 77mm Variable Neutral Density filter. If you use a 77mm variable ND filter on a 67mm lens with a step up ring, this will help to decrease vignetting, yes. There is, however, no guarantee that vignetting can be eliminated in this way.

Q: 2. Does this fit Nikon Lens threads?

A: Peter, B&H lists the lens filter thread specifications at the web page below as having a 1.0 pitch, which is a coarse thread.a href= http://www.bhphotovideo.com/c/product/1175034-REG/nikon_af_s_nikkor_200_500mm_f_5_6e.html target= _blank http://www.bhphotovideo.com/c/product/1175034-REG/nikon_af_s_nikkor_200_500mm_f_5_6e.html/a

Q: 3. Will this 67mm filter works on Tamron 28-200? Worrying it will not work on the wide end of the lens.

A: Yes Tiffen 67mm Variable Neutral Density Filter will fit the Tamron 28-200mm f/2.8-5.6 Di III RXD Lens for Sony E. 28mm is not extremely wide so it should not vignette.

Q: 4. what size lens cap to buy for the 52mm?

A: I would recommend the Kaiser 57mm Push-On Lens Cap, B&H # KALC57, as a slip-on lens cap for use on the Tiffen 52mm Variable Neutral Density Filter, or the slightly smaller Kaiser 56mm Push-On Lens Cap. B&H # KALC56, for a more snug fit.

Q: 5. CAN I ADD ANOTHER FILTER OVER IT LIKE THE Tiffen 77mm Black Pro-Mist 1/8?

A: This Tiffen 77mm Variable Neutral Density Filter does not have front threads. If you were you stack it the filters, the Tiffen 77mm Black Pro-Mist 1/8 would have to go on the lens first followed by the Variable ND.

Q: 6. what is the definition of coarse thread ?

A: Coarse thread would refer to a lens filter with a pitch of 1, instead of the standard 0.75 pitch. Most filters between 39-82mm and 127mm use the 0.75 standard pitch. Filters sized 86-112mm and 122mm are typicially 1 pitch, or coarse thread. In any case, you simply need to purchase the filter that is designed for the filter thread size of your lens. The manufacturers concern themselves with making the correct pitch or thread size for the designated filter size.

Q: 7. can i use it with canon lenses such as 70-200mm, or 50 mm?

A: The Tiffen 77mm Variable Neutral Density Filter can be used with lenses that have a filter thread of 77mm. The Canon 70-200mm f/2.8L has a filter thread of 77mm, and lens and filter combination is compatible. However, the Canon 70-200mm f/4L has a filter thread of 67mm and will need a 67mm filter bhpho.to/1lkVPtOThere are numerous versions of the Canon 50mm lens, and none of these lenses have a filter thread of 77mm. For the Canon 50mm f/1.2L, you will need a filter with a thread size of 72mm http://bhpho.to/1pBQ3VJ, the 50mm f/1.4 will need a filter thread size of 58mm http://bhpho.to/Urhszp, and the 50mm f/1.8 will need a filter with a thread size of 52mm http://bhpho.to/1kML3gr

Q: 8. Can this fit any 72mm lens. I have a canon rebel T5 with 18-200 lens that is 72mm?

A: Yes, the Tiffen 72mm Variable Neutral Density Filter will fit any lens with a 72mm diameter filter thread, including the Canon EF-S 18-200mm lens.

Q: 9. I can see a bit of threading on the front of the 62mm and 67mm Tiffen VNDs. Can you tell me what the diameter is of each of those? I realize it is not much, but it is there, and I would like to try and use it.

A: Unfortunately the Tiffen VND filters do not have front threads. The front of the filter is larger than the rear threads in order to reduce the risk of vignetting.

Q: 10. Can you or should you stack a ND Filter over a Circular Polarizer?

A: If the Circular Polarizer filter attached to the camera female filter threads on the front of the filter, then yes, it is possible to stack an ND filter on the front of the lens. Depending on the filters' thickness and the lens' focal length, this may cause some vignetting in the corners of the image, but it is possible for usage when you need both darkening of the scene as well as polarization of the scene.
