This 52mm Tiffen Water White Glass NATural IRND Filter is a neutral density filter with a 128x filter factor that provides a 7-stop exposure reduction. Its 2.1 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 are intended to not affect the coloration of the image and are ideal for pairing with other filters.

The design of this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible light and infrared light. Due to imaging sensors' greater susceptibility to infrared light, compared to traditional film, color casts can occur when photographing darker subjects that require increased exposure times.

This filter is noncoated, is constructed from Water White glass for increased clarity, and features an aluminum-alloy filter ring for durability while remaining lightweight. It 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.

Q: 1. Will this filter work on a wide angle lens such that there is no vignetting or blocked portions on the image?

A: We use the 52mm as a drop-in for a 200-400 f4 Nikon lens. No problem there.

Q: 2. Hi there! Does this filter have front threads? Thanks!

A: The Hoya 82mm ND (NDX8) 0.9 Filter (3-Stop) does have 82mm front filter threads.

Q: 3. Is this filter fit with fujinon 35mm lense?

A: There are several Fujinon 35mm lenses listed here on B&H and none of them seem to have a 43mm filter size. However, it could simply be that your lens isn't for sale here. Without more information on the lens this question cannot be answered. Can you provide more information about exactly which model of 35mm Fujinon lens you have?

Q: 4. I already bought 3 stop filter of this. Can you help me where I can get 6 stop filter?

A: Here is the link for a high quality 77mm 6 stop filter by Hoya. https://www.bhphotovideo.com/c/product/1012350-REG/hoya_xpd_77nd64_77mm_pro_nd_64x.html

Q: 5. HelloWould this Filter and the Hoya 52mm Alpha Circular Polarizer Filter work (Compatible) with Panasonic Lumix FZ200?Thank you.Shaun

A: The sizes of both filters are the proper size for the FZ200 and will properly fit it, however Panasonic's instruction for the manual discourages use of two filters on the camera, likely as it will become too darkened for the camera to autofocus with.

Q: 6. Any vignetting when mounted on a Zeiss 15mm lenses?

A: Depending on the sensor size of the camera, you may experience vignette using this polarizer on a 15mm lens.

Q: 7. Anyone know if this would vignette on a 16mm on full frame? I primarily shoot a Nikon 16-35 on a D850.

A: This will not vignette on 16-35mm if you do not stack it over UV filter

Q: 8. How does the K&F Light Pollution Filter compare to the Hoya Starscape Light Pollution Filter?

A: This K&F filter would offer a knurled ring and water/scratch resistance over the Hoya model.

Q: 9. Will this fit onto a Moment lens 62mm Filter Mount?

A: Yes.

Q: 10. Is this compatible with a 40mm lens?
