Haida Interchangeable Magnetic Variable ND filter 77mm.

Introduction;

Haida kindly invited me to evaluate their latest innovation; Interchangeable Magnetic Variable Neutral Density (ND) Filter (2-5 stops & 6-9 stops). My test review will be in two parts, this being part 1 testing the 2-5 stop Magnetic Variable ND filter which not only is the perfect tool for photographers but also videographers. In other words, one filter ranging from 2- 5 stops and another from 6- 9 stops interchangeable in 1 second, yes I did say that correctly, one second!! Have I got you intrigued now? Let me walk you through & you show you this great innovation. Do I sound biased already? I’m sorry I am, but I will be honest & tell you some downsides

I will be testing for optimal sharpness, tonality, vignetting, bokeh, X-pattern issues, design, functionality, accuracy of stops & colour shifts.

What is a Variable Neutral Density (ND) Filter & how does it work?

Basically a Variable ND filter works by using two pieces of polarised glass that darken as they oppose each other, creating the lovely ND filter effect. As you rotate the filter the density is increased or decreased affecting the amount of light that falls through the lens & onto the camera sensor.

Sizes; 

Available in various sizes; 58, 62, 67, 72, 77 & 82mm. I’m using is the 77mm as my lens is a Canon 70-200mm F2.8 (ii).

NanoPro;

Featuring a NanoPro multi-coating on the filter glass, which helps prevent dirt and smudges from adhering to the glass, reduce reflections, scratch and water proof. Applied to both sides of the filter and helps prevent color cast while maintaining image sharpness. The Haida Nano pro filters are highly scratch-resistant, durable and super easy cleaning.

Positive features (in no particular order)

  • Filter protector cap.
  • Sleek design.
  • Accurate placed stop numbers.
  • No X pattern.
  • No colour shift ( neutrality).
  • Great contrast & tonality throughout.
  • Sharpness.
  • No vignetting.
  • Magnetic attraction.
  • Ease/speed of use.
  • Exceptional image quality.
  • Hard stops at each end which works as a bit of a fail safe. Preventing you from going past the weakest or strongest points, therefore impossible to push the ND effect too far. You simply place the marker over whatever number you want. This means you won’t suffer from entering into the infuriating X pattern (produces hatched areas on the actual image) terrority.
  • Absolutely no light leakage.
  • The ability to control your shutter speed in ever-changing lighting conditions
  • Incredibly smooth rotation in hand with enough friction enabling you to easily rotate the filter to the precise stop required.
  • Ideally suited for all types of photo &/or video genres including portraiture. I will be using it for my animal work.

Negatives

  • I’m still undecided if I would have preferred an adjustment peg on the side to make it a bit easier to rotate from stop to stop without getting greasy fingerprints on the glass from my clumsy fingers or if it’s best without. Certainly not having it makes for a super sleek design which I really do like, not only visually but for storage & less weight. Over time I have gotten used to moving it without intensely watching where every stop is.

For the traveller in mind

If you’re tired of hauling around lots of different filters on your travels & need to go lightweight this could well be your answer.

In the field tests

Test shots at different focal lengths starting at 70mm to 200mm in 10mm increments at each stop on the filter to see if all stops are true & consistent.

Sunset images below taken with Canon 5d mark iv, Canon 70-200mm F2.8 (ii) lens on Gitzo tripod. Settings used; Without filter = ISO 100, F11, 1/60 – With Magnetic Variable ND filter 2-5 @ 3 stops; ISO 200, F11, 1/8 @70mm.

Without/ with filter.

Very pleased to tell you my field test was successful in checking the stop numbers are accurately placed.

Conclusion

So far the most versatile filter I’ve ever used, certainly the most enjoyable, easiest, fastest & most practical system. The innovation and thought gone into the design/ build, coupled with the high quality optics makes this filter an incredible piece of kit & serious contender in the photography/ videography marketplace for many types of genres.

All Haida filters are assembled in their own optical workshop located in the beautiful Port City of Ningbo, China. If you’d like to visit their website &/or Facebook .
