This 1-stop, 52mm Heliopan ND Filter is an ND filter with a 2x filter factor that provides a 1-stop exposure reduction. Its 0.3 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time, you can create motion blur for special effects or to convey a sense of movement. Opening your iris allows you to create shallow depth of field, which can help isolate your subject. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

To prevent internal ghosting and reflections, each glass surface includes four layers of anti-reflection coating. Together, these eight coatings offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters.

This Heliopan neutral density filter is constructed from Schott glass for increased optical clarity as well as color fidelity and features a brass filter ring for enhanced durability and jamming prevention.

Related Questions and Answers

Q: 1. 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: 2. is this ND filter ideal for video use? I plan on using it with a Sony FDR-AX33 4K camera.

A: Actually the newest ND filter by Hoya (the SOLAS filter series) would be more suited for video work:https://a href= http://www.bhphotovideo.com/c/product/1285182-REG/hoya_xsl_46irnd09_46mm_solas_0_9_irnd.html target= _blank www.bhphotovideo.com/c/product/1285182-REG/hoya_xsl_46irnd09_46mm_solas_0_9_irnd.html/a

Q: 3. 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: 4. Can two of the Hoya 49mm Neutral Density (NDX8) 0.9 be stacked for additional density?

A: Yes you could... but I would not. That is extra glass surface to catch light and cause distortion and reflection. If this was an expensive lens with perfect coatings... what I caution you on would not be an issue. I would not.

Q: 5. Is this recommended for digital cameras?

A: The Hoya 72mm Neutral Density (ND) 0.3 Hoya Multi-Coated (HMC) Glass Filter is recommended for both digital and film cameras. Hoya's Pro Digital line of filters are slimmer but still have threading on both sides of the filter. Ultra-thin filter frames help to avoid vignetting on super wide angle lenses while the front threads mean they will also hold a lens cap. HMC filters feature a 3 layer multi-coating while their Pro Digital line's multi-coating is optimized for use with digital sensors.

Q: 6. what is difference between this and Hoya 77mm NDx400 HMC Filter B&H # HOND400MC77 MFR # A77ND400 (https://a href= http://www.bhphotovideo.com/c/product/155266-REG/Hoya_A77ND400_77_mm_Neutral_Density.html target= _blank www.bhphotovideo.com/c/product/155266-REG/Hoya_A77ND400_77_mm_Neutral_Density.html/a) ?

A: The Hoya ND4 only loses two stops of light, while the ND400 loses around 9 stops. The ND400 is a darker density that the ND4.

Q: 7. Has anyone tried this on the Rokinon/Samyang 12mm? Any issues with fit and/or vignetting?

A: You will probably experience vignetting with this combination, as the HMC filter line are not thin filters.

Q: 8. is this compatible with a 50mm sony lens?

A: Yes it is.

Q: 9. Does this filter case any noticable vignette?

A: No.

Q: 10. Hi Do you have the B+W series 7 0.9 ND filter?

A: The nearest option would this 2 stop version: https://bhpho.to/3x5JhyN Series size filters are only made for older lenses so the filter selection will be rather limited.
