The Sigma 105mm Protector Filter is a simple, clear filter with a 1x filter factor and is designed to provide general protection for your lens. This optically clear filter does not affect overall image quality while helping to prevent dust, scratches, moisture, and other elements from reaching or damaging your lens. This filter is multi-coated which helps to eliminate internal ghosting and reflections.

Sigma Protector filters are constructed from optical glass with a black rim. Set within an aluminum-alloy filter ring that is durable while remaining lightweight, the glass provides increased clarity as well as color fidelity while the black rim further ensures that reflections do not occur along the filter's edge.

Q: 1. Hello, does it fit to the Nikon AF-S 24-70 f/2.8E ED VR?

A: Yes, the Sigma 82mm WR Ceramic Protector Filter can fit the Nikon AF-S NIKKOR 24-70mm f/2.8E ED VR Lens.

Q: 2. Is the filter frame aluminum or brass?

A: The ring on this filter is aluminum.

Q: 3. How effective is the hydrophobic treatment? Presumably a titanium oxide coating?

A: Hydrophobic and oleophobic coatings on glass elements and filters such as the Sigma 95mm WR Ceramic Protector Filter (B&H# SICGC95) are typically fluorine-based rather than titanium-based, as the later would block much visible light. It causes most water to bead and roll off if there is any incline to the angle at which the filter is held. When dealing with water droplets and splashes, I have found this type of coating sheds most water without my needing to address it at all. When a water droplet does not roll off right away, I just blow on it to shed it without having to take a break to wipe the lens or filter. I do not need to touch the element at all and I'm immediately back to shooting.

Q: 4. Is this filter ring in black? (Not silver one). I would like to buy it to match with my X100T Black.

A: The PRF49S listed on B&H's site is silver and matches the silver version of X100T / X100S / X100. Fujifilm did inlude the black version with the special edittion (black) of the X100 but I do not know if it is avaiable separately. Nonetheless, why not use a top notch B&W filter -- in black? The motivation behindf the Fujifilm silver filter is to match the camera. This will not be a problem with the B&W filter and a black X100T.

Q: 5. s9900w can use?

A: The FinePix S9900W does not list a 58mm filter thread to attach this filter. According to Fujifilm it will not be compatible.

Q: 6. Will this vignette with an 18mm lens? Specifically the Tamron 18-300 (67mm). Any issues with the hood fitting properly?

A: This filter will not vignette unless it's wider than 16mm on a full frame camera. You shouldn't have any issues fitting the lens hood over the filter either.

Q: 7. I'm having difficulty opening the case for the first time in which the Sigma 95 mm WR Filter is packed. I've tried twisting it and cannot find any plastic sealant. I would appreciate direction. Suggestions?

A: For the case of the Sigma 95mm WR Ceramic Protector Filter one can turn the top part of the case counter clockwise and then simply pull it off.

Q: 8. Is this available in silver?

A: We do not carry a silver version of this model.

Q: 9. Does anyone know the thickness of this filter in millimeters?

A: Fully threaded onto the 23mm lens on the x100f, the filter extends approx. 4.8 mm (measured with a scale).

Q: 10. Will this work with my X-T3 Mirrorless Camera with XF18-55mm F2.8-4 R LM OIS Lens? Thanks

A: Yes, It works great !
