This 55mm Tiffen Water White Glass NATural IRND Filter is a neutral density filter with a 64x filter factor that provides a 6-stop exposure reduction. Its 1.8 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. Real-life experience comparison regarding the 'water repellant' coating of this filter vs., say, the B + W circular pola? Any difference in environments with rain/snow/humidity? Thanks.

A: Yes, the water repellent works quite well when it comes cleaning the filter without leaving streaks,etc...,as well as not fogging up.

Q: 2. I have a Nikon 50mm f/1.4 lens with a good. The lens cap fits inside the lens and it says 58mm. Will this lens filter fit this lens?

A: Yes, any 58mm filter will fit.

Q: 3. any noticeable loss of image quality (especially sharpness) with this ND filter? Thank you

A: I was just now looking at the same subject shot with and without my Bower 52mm variable ND. And I didn't see the filter adding any softness at all. I'll do some more testing but I just don't see a problem at this point. Seems like a great value for 25 bucks. I suspect people may be shooting wide open, getting suboptimal sharpness, and blaming the filter.

Q: 4. Will this work with the LEE Filters 105mm Accessory Front Thread Adapter Ring &H # LEFARPFK105?

A: yes, it will fit perfectly on the LEE Filters 105mm Accessory Front Thread Adapter Ring.

Q: 5. I have a vivitar 0.43x wide angle filter that accepts 62mm filter threads. I'm considering getting this Bower 62mm Variable ND filter and a 58-62 step up ring so I can use it on both the wide angle filter and my Canon G40's lens. My question is; would there be any amount of vignetting that would render the use of the ND filter on the wide angle filter pointless? How much of a vignette should I expect?

A: I can confirm what Roland said, this filter becomes unusable at its maximum/darkest setting. Roll it back just a bit and it's fine, but do keep that in mind.

Q: 6. What diameter lens cover will fit over this filter please?

A: The lens cover for your lens should fit over the filter. So if your lens is 95mm, and your filter is 95mm, then you need a 95mm lens cover.

Q: 7. Is the front threaded? For protective Cap Storage?

A: Yes, it has a 95mm front thread.

Q: 8. Any vignetting when mounted on a Zeiss 15mm lenses on Nikon D810?

A: This filter may cause vignette when mounted on a full frame camera and 15mm lens.

Q: 9. Hi I have a canon 50mm 1.8 stm lens will this fit on it thankyou

A: No,canon filter size is 49mm.You should buy 49mm variable neutral density filter.

Q: 10. Does it come with a case?

A: No sadly it is just a plastic display case.
