This 55mm Urth ND Lens Filter 55mm 4-Stop Plus+from Urth ND Lens Filter 55mm 4-Stop Plus+provides a fixed 4-stop light reduction for better control with long exposure and depth of field techniques in low light. With less light entering your camera, you can also use wider apertures in low light for a beautiful shallower depth of field effect without overexposing images. Cinematographers can use the ND16 Filter Plus+ to create more cinematic effects in low light without losing quality or overexposing the shot. The Plus+ range features 20-layers of nano-coating providing easier cleaning and better protection against water, oil, and scratches. These layers also provide a higher maximum light transmission and a more consistent transmission curve for truer light reduction.

1.2 Optical Density    20-Layer Nano-Coating    B270 Schott Optical Glass    Ultra-Slim Rim    Double-Threaded for Stacking Filters

The fixed ND16 Filter Plus+ lets you capture motion blur and depth of field effects in low light. It is great for landscape photography and cinematic effects in videography.

Reduce light to 6.25% to maintain you desired settings in overly bright conditions or create dramatic motion blur and shallow depth of field in low light conditions.

The filter is double-threaded for stacking filters or using screw-mount lens caps.

The B270 Schott optical glass is coated with a 20-layer nano-coating for truer light transmittance, better protection, and easier cleaning.

The consciously designed ultra-slim rim avoids vignetting and our durable magnalium is guaranteed for life.

Q: 1. Hi,I was wondering 2 things about this filter:* does it have hard stops ?* what is the size of the front filter ? is it 62mm ? thanks

A: This B+W 62mm XS-Pro Digital ND Vario MRC nano Filter has hard stops from +1 to +5 stops. The front thread size on this filter is 67mm; in order to avoid vignetting, the front filter thread is oversized.

Q: 2. The description says the iris is clickless. However, the recent Viltrox 23mm 1.4 is also clickless, yet people point out that on a Fuji X-T3 this is pointless as the camera will only adjust the blades in steps - or clicks, if you will. This is because the aperture is not really controlled by the ring on the lens but by the camera, which wants to change the aperture in steps. So, on the Viltrox, you cannot video a smooth aperture change. So my question is, would the X-T3 have the same effect on the aperture of this lens? It would be great to find out from someone with actual experience with this lens.

A: The Viltrox 23mm f/1.4 has an electronically controlled aperture with a manual override option, which may vary in support between cameras and with internal aperture settings. The FUJIFILM MKX18-55mm T2.9 Lens however, is a fully manual operated cinema zoom lens and will not change from internal camera settings electronically.

Q: 3. is a five stop density enough to get the milky effect on water falls and ocean ? I am also looking to photograph motion ( still images) not sure if if i need a denser filter or five stops should suffice.

A: It would mainly depend on the amount of ambient light on the scene and your camera's settings as to if 5-stops would be enough for your needs. For most lenses, and if using the camera's lowest ISO setting, 5-stops should be enough for you to create a situation to have a shutter speed between 1/4 sec to 4 seconds, depending on the type of waterfall and available light restraints. If you use a low ISO, a mid- to small aperture, and a shutter speed between 1/4 sec to 4 seconds (or test for your needs), then the B+W 82mm XS-Pro Digital ND Vario MRC nano Filter would work for your needs.

Q: 4. I purchased this filter from you earlier this month. The filter ring is oversized . Can you recommend a lens cap that would work with this filter? Thank you. - Michael

A: The front filter thread size of the B+W 72mm XS-Pro Digital ND Vario MRC nano Filter is 77mm. As such, any 77mm lens cap should fit onto the filter. If you need a particular recommendation, then I would recommend the Sensei 77mm Center Pinch Snap-On Lens Cap, B&H # SELC77, for your stated needs.

Q: 5. I regard to the question about the front threads:Note that the specs supplied by B&H say that the mfg has not provided that info. Upon receiving this filter hoping I could add the the Nikon R1C1 flash system to it (the reason I bought this unit instead of others that had no front threads) I can tell you that the threads are well over 77MM wide. I should have figured that out when the description states the filter is oversized.

A: The front threads are approximately 81mm on the XS-Pro 77mm Digital ND Vario. While it will not be possible to use the R1-C1 mounted on this filter, the flashes on the R1-C1 separate off the ring and the system comes with stands. You could mount the flashes onto stands and ultimately a tripod and light the subject in this manner, and just use the system without having the flash on the camera.

Q: 6. does it come with the lens hood?

A: Product is listed to come with a lens hood.

Q: 7. Is this an active lens with electronic contacts to communicate to an x-mount Fuji camera?

A: No. The following does not offer any native on-board contacts.

Q: 8. Can someone confirm if this 95mm still allows for the Sony 28-135mm factory hood to be mounted with the filter on? Thank you!

A: It does not allow for the factory hood to mount - it is too big for the hood to slide over the filter.

Q: 9. Can I change the mount to mft mount, so I can switch this lens between my fuji and my gh5?

A: We're afraid not. Interchangeable mounts are not available for this product.

Q: 10. Hello...what is the front filter thread size (i.e., for attaching other filters, etc).Thanks

A: The 67mm XS-Pro Digital ND Vario MRC nano Filter has a 72mm filter thread.
