Aurora-Aperture PXND-II-128-72 Overview

  • 1Description

The 72mm Power XND Mark II Variable ND 0.3 to 2.1 Filter from Aurora Aperture is a variable neutral density filter that is designed to mount onto lenses with 72mm front filter threads and provides an exposure reduction of 1 to 7 stops. Its 0.3 to 2.1 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the front filter ring, helping you to predetermine the additional exposure length required. By increasing your aperture or slowing your exposure time, you are able to control depth of field and convey movement more easily. For easier, repeatable control over density settings, the front ring is visually demarcated with numbers representing different density values and includes a rotation lever to further enable fast and precise positioning of the front ring.

This filter is constructed from Schott B270 glass for increased optical clarity as well as color fidelity, and each glass surface is multi-coated to prevent ghosting as well as reflections. The nano coating associated with the 72mm Power XND Mark II Variable Neutral Density 0.3 to 2.1 Filter provides an additional layer that allows for more efficient cleaning when its surfaces come in contact with dust, dirt, water, or oil.

Variable neutral density filter allows you to apply differing amounts of density from scene to scene.
0.3 to 2.1 neutral density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.
2x to 128x filter factor provides an exposure reduction of 1 to 7 stops, allowing you to control depth of field and convey movement more easily.
Offers increased flexibility to use specific ISO settings or ISO films under bright ambient light.
Provides increased exposure flexibility while using cinema or video cameras within a designated film frame rate.
Constructed from Schott B270 glass for increased optical clarity and color fidelity.
Multi-coated to prevent ghosting as well as reflections.
Nano coating allows for more efficient cleaning when the filter's surfaces come in contact with dust, dirt, water, or oil.
Durable and lightweight aluminum-alloy filter ring assembly with 72mm front filter threads allows for use with other filters.
6.0-thick aluminum-alloy filter ring assembly helps minimize the potential for vignetting.
Removable side lever allows the filter glass to be easily rotated.
Front filter ring constructed to help ensure that its rotation corresponds to the filter's exposure reduction range.

    Aurora-Aperture PXND-II-128-72 Reviews

    72mm Power XND Mark II Variable ND 0.3 to 2.1 Filter (1 to 7-Stop) is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from One of the best variable ND filters available I dont usually write reviews, but I couldnt find a good comparison between many of the most popular/recommended variable ND filters, so I purchased six of them to test them out and compare them to each other. Note that I purchased these filters for video, not photography use. Skip to the end if you only want to know which one I purchased and why. Here are the six filters I tested, from cheapest to most expensive: - Ritz Gear™ Premium HD MC Fader ND Filter (~$20) - Zomei Fader ND Neutral Density Adjustable Variable Filter (~$30) - Tiffen Variable Neutral Density Filter ($130) - Aurora-Aperture Power XND 128 Mark II ($139) - Genustech Eclipse ND Fader Filter ($149) - SLR Magic Self-Locking Variable Neutral Density 0.4 to 1.8 Filter ($179) First, some observations I had while using each of the filters: Ritz Gear - Smooth, but slightly too hard to turn - No hard stops - Doesnt always thread properly on lens Zomei - Smooth to turn - Has hard stops - About as thin as Aurora-Aperture Tiffen - Mostly smooth to turn - No hard stops - Feels well-made - Somewhat thick/heavy Aurora-Aperture Power XND - Smooth to turn - Thinnest and smallest of the bunch - Can attach lens cap to front of filter - Has hard stops and small lever - Lever can end up on wrong side of lens with no way to adjust Genustech Eclipse - Smooth to turn - No hard stops - Feels well-made, probably best of the bunch SLR Magic - Smooth to turn, but front of filter feels slightly loose - Big and bulky - Difficult to thread because of extra spinning filter ring - Has hard stops and long lever - Not impressed with build quality/design for the price In terms of build quality/design, I ranked the six filters from best to worst, in my opinion: 1. Genustech 2. Tiffen 3. Aurora-Aperture 4. Zomei 5. Ritz Gear 6. SLR Magic Next, I did four different test shots with no filter and then with each of the six filters, then ranked the filters in terms of color accuracy and sharpness for each test, then averaged the results. I used manual white balance and manual focus for all tests. I was disappointed to find that all the filters had pretty significant yellow/green color shifts in almost all of the tests when compared to the tests with no filter. If color accuracy is your greatest concern, I would skip variable ND filters entirely and buy a solid ND filter like the Breakthrough Photography X4 ND. I also found that while some filters generally performed better than others, there was a large variation in color accuracy even between the same filter in different tests. Still, the Aurora-Aperture, SLR Magic, and even Zomei produced noticeably more natural results than the rest. The Genustech, Tiffen, and Ritz Gear had more of the yellow/green tint than the better-performing filters. Heres how the filters ranked in terms of color accuracy (from best to worst): 1. Aurora-Aperture 2. SLR Magic 3. Zomei 4. Genustech 5. Tiffen 6. Ritz Gear Testing the sharpness of the six filters, I found that the two cheapest filters, the Ritz Gear and the Zomei, CONSIDERABLY softened the image, while the other four filters were very similar in terms of sharpness. In a wide shot, it was hard to tell a difference between any of them, but with a telephoto lens, the image from the Ritz Gear and the Zomei were completely unusable. Of the four more expensive filters, I found the Tiffen, Aurora-Aperture, and SLR Magic were almost identical in terms of sharpness (very good), while the Genustech edged them all out just slightly. I was only able to tell that the Genustech was noticeably sharper in one of the tests. I was not able to notice any loss in sharpness between the shot with no filter and the shot with the Genustech. Heres how the filters ranked in terms of sharpness (from best to worst): 1. Genustech 2. Tiffen 3/4. (tied) Aurora-Aperture and SLR Magic 5. Zomei 6. Ritz Gear Finally, I averaged together the results of the build quality/design, color accuracy, and sharpness tests. Heres how the filters ranked overall in my very non-scientific testing: 1/2. (tied) Genustech and Aurora-Aperture 3/4. (tied) SLR Magic and Tiffen 5. Zomei 6. Ritz Gear After doing these tests, I was planning on buying the Genustech for its sharpness and build quality/design, but upon reviewing my results again I found that the colors on the Aurora-Aperture were not only more accurate but also more pleasing to me in 3/4 of the tests, whereas there were only 1/4 tests were I could tell that the Genustech was sharper. In the end, I ended up keeping the Aurora-Aperture and returning the rest, but I dont think you can go wrong with either of the four more expensive filters, especially the Aurora-Aperture and Genustech.
