The 10-stop, 30mm Heliopan ND Filter provides a 10-stop exposure reduction. Its 3.0 optical 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.

Q: 1. Is there a Canon version?

A: Zuiko makes lens for Olympus but can be used on other 4/3 cameras such as Panisonic.

Q: 2. I use a Panasonic G7 with a Speedbooster to be able to adapt Nikon mount. I was wondering how this lens compare to the Sigma 30mm 1.4 for Micro Four thirds? I know that the native 30 mm for M43 would give me the equivalent of a 60 mm on my G7 and this lens would be closer to a 45mm once mounted on the focal reducer, but I'm wondering about the quality here?

A: A Sigma 30mm f/1.4 DC HSM Art Lens for Nikon B&H # SI3014DCHSMN would be a very sharp lens to use with the G7, but where the image quality is on par with using a Nikon F mount lens on a Metabones SpeedBooster really depends on which lens that actually is. Also, a direct fitment to the camera means a lighter camera set up and autofocus, which using the adapter will not give you.

Q: 3. Full frame

A: The Sigma 30mm f/1.4 DC HSM Art Lens for Canon EF is for crop frame cameras. It will fit a full frame camera but you might see vignetting on the edges unless you set the camera to crop mode.

Q: 4. What the heck is an Art lens??? This just looks like a nice normal lens for APS-C.

A: idk I just bought this for decoration

Q: 5. Can this lens be used with the Canon 90D?

A: You would be able to use this lens with the Canon 90D.

Q: 6. Does this lens resist cold or hot well?

A: I went to Iceland in April and it was pretty cold. This lens was on the camera 90% of the time 2000 pics. The lens held up well against the cold and light rain. Be aware that I was using a rain cover to protect the lens and a6000 during significant down pour. I was little paranoid that one day I will wake up and see condensation on the inside but it never happened... Even when I didn't take extreme care to acclimate the lens when going from cold outside to warm inside. After 2 yrs it is still going well. Focus is smooth as ever and focus by wire mechanism is also very smooth.

Q: 7. Has anyone used this lens on a D810 in 1.2x crop mode? Is there vignetting at 1.2x? Thanks

A: With this lens on the D810, if you put it into 1.2x crop, there is no noticeable vignetting.

Q: 8. Does this lens has an internal focusing mechanism? In other words, does this lens maintain fixed external dimensions while focusing?

A: Yes

Q: 9. May I know what canon cameras can you use with this lens ?

A: 70d

Q: 10. will this fit on a Nikon d60?

A: As the Sigma 30mm f/1.4 DC HSM Lens for Nikon DSLR Cameras has Sigma's HSM Hypersonic Motor built into the lens, it would be fully compatible for use on the Nikon D60 DSLR Camera.
