Offering increased control over exposures, this Pro Ultra Slim ND Filter from Fotodiox features a 145mm front filter thread, and is used to darken the entire image, thereby allowing you to increase exposure times or to work with a wider aperture setting than without the filter while maintaing the correct exposure. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. The ND 1.2 density of this filter requires a 4-stop increase in exposure to achieve a normal exposure.

The filter is made from optical glass, which has been multi-coated to maintain image quality when working in strong lighting conditions. The glass is set in a 3mm-thick anodized aluminum ring that is lightweight, durable, and slim to help prevent vignetting when used with wide-angle lenses.

Q: 1. does this work for the tokina 16-28mm pro system?

Q: 2. How is the image quality of this filter glass in comparison to LEE filter glass?

A: The image quality of the FotodioX 186mm Slim ND 3.0 Filter (10-Stop) is neutral, and will not get in the way of the sharpness or colorization of the lens it is mounted to. The Lee filters are not available in a circular 186mm.

Q: 3. 145mm Neutral Density 32 Filter for WonderPana 145/66 Systems by FotodioX Can these filters be stacked ?

Q: 4. This filter will fit the lens to the Sigma 300-800?

A: The Sigma 300-800m zoom has a 165mm front diameter. The Fotodiox UV filter is only 145mm, so I doubt if this filter will fit the lens in question....

Q: 5. has anyone out there used this on the nikor 14-24mm and how did they find it worked?

Q: 7. Will these Formatt 46mm Firecrest Ultras fit the Z800 mm as screw in filters?

A: The Nikon 52mm Circular Polarizer (C-PL3L) Glass Filter compatible with the Nikon NIKKOR Z 800mm f/6.3 VR S Lens does not allow the 46 mm polarizing filter to come off and to be changed with another filter so this Formatt Hitech 46mm Firecrest Ultra ND 0.9 Filter can't be used.

Q: 8. 1. Can this circ-polarizer be stacked with a wonder-pana solid ND filter? e.g. using both polariser and ND-8 filter (or ND-32 filter) together? 2. If they can be stacked, will vignetting be observed on the Nikon 14-24 with two circular filters stacked? 3. Can we stack a circular wonderpana 145 filter with their rectangular 66 graduated ND filters? 4. If we can stack a circular with rectangular GND, will vignetting be observed on the Nikon 14-24 with total 2 filters (1 circular and 1 rectangular)?Thank you!

A: WonderPana 145/66 system allows stacking of one round filter like the polarizer and one rectangle filter or two rectangle filters. With the adapter for the Nikon 14-24 lens you can use this set up on that lens.It is designed not to vignette.

Q: 9. Disregard its size, did anyone find this multi-coated UV filter degrade the image quality, such as sharpness?

A: When using the FotodioX 186mm Slim Multi-Coated UV Filter users have experienced no degradation of image quality, because the filter is made with optical glass and multicoated. The thin rim prevents vignetting, and the UV coating will help prevent glare from the sun.

Q: 10. what is filter thickness?

A: I REALLY DO NOT HAVE A DEMININSION IT IS THE SLIM FILTER THAT IS ALL I CAN TELL YOU.
