As you can see, there’s now little-to-no difference between the control and the Freewell 2-5 stop VND image. What this means overall is a little extra time in post color correcting photos and videos (which needs to be done anyway as evidenced by color cast in the control image as well). Lastly, I zoomed into 200% on the images taken at f8 with my 70-200mm lens to show potential sharpness loss. Such detail likely won't come through after jpeg compression and resizing for this article but trust me when I say I see no loss in sharpness or detail in the image, which is great. Quite frankly, K&F Concept’s filters performed much better than expectations. They can easily stand their ground against filters from better-known brands. These results are excellent. In Use Bernard Dery | Light And Matter CPL at 20mm One other advantage of the K&F Concept filters is that they are available for a wide range of diameters, starting at 49mm, as opposed to 67mm for some competitors.

Quality neutral density filters darken photos and videos without affecting color. A filter with high color accuracy contributes less color cast, which translates into less work in post fixing what the filter added. Gear and rope constantly bumped against my camera while I had it out. The clear UV filter gave some nice peace of mind to know that the glass of my actual lens, was totally safe. Colour Cast and Quality Of The Freewell Magnetic Polarizer Filter The downside to this filter is the colour cast. I personally am not a big fan of the green cast so I’ll have to correct that in post, each time I use this filter. If you do not like to post process your images, this may be a bigger issue to you.

When I tested the PolarPro and Moment VND filters in the past, I found that neither of them were perfectly accurate in terms of their f-stop designations. Both filter brands promised 3 full f-stops (EVs) worth of density, but only provided 2 1/3rd stops. I took the Freewell Magnetic Polarizer Filter on a multi pitch adventure up the Stawamus Chief in Squamish, BC. I thought if I had no issues with it while dangling 2000ft above the ground, then there certainly would be no problems at ground level. Our approximate route. Maybe the most exposed filter review anyone has ever made? What’s The Point Of A Polarizer In Photography? To test color accuracy, I captured a number of RAW images using a Canon EOS R5 in a controlled studio environment. Both the camera and light were set to 5600 kelvin, and the same exposure settings were used at all times (with the exception of shutter speed to match exposure). All images shown below are straight-out-of-camera with no adjustments in post. The Freewell magnetic VND system may be used with circular filter threads measuring 58, 62, 67, 72, 77, 82 or 95mm in diameter. Feel free to ask me specific questions I might not have covered throughout this review or simply let me know what you thought. As always thanks for watching, reading, or both.

A polarizer is a great filter to help cut glare and enhance colours. By rotating the filter you are able to target different areas of glare in your frame. A polarizing filter is also extremely useful when shooting in an area with lots of highlight since it helps to get a more balanced exposure. This Freewell filter system actually comes in two pieces. The actual filter (ND, POLA ETC.) and a magnetic clear UV filter. The clear UV filter has a magnetic ring that screws into the threads of your lens and can stay attached permanently if you wish. Colour cast is the hue that the filter gives your image. Kind of like how your sunglasses change the tint of everything you see, filters do the same for our cameras. Colour cast isn’t always a bad thing, however; some colour casts are more pleasing than others. The Freewell Magnetic VND system is available in 58, 62, 67, 72, 77, 82 and 95mm diameters and comes with all of the following components:I was expecting similar performance here with the Freewell filters, but I’m happy to report that they actually do a significantly better, as long as you don’t pay attention to the numbers on the edge of the filters too much. J. Matthew Gore Beach #3 on the Washington Coast, Freewell 2-5 Stop VND

Flip the 2-5 stop VND filter around and it becomes a circular polarizer; flip the 6-9 stop VND around, and it becomes an ND32 polarizer. Want a glow mist filter as well? Simply pop out the 1-stop glass in the VND Base, replace it with the MistxVND Base and you get a 1/8 diffusion filter. Rotating a CPL filter with the M2 system is a straightforward process. We’ve made it simple and intuitive to adjust the polarizer to achieve your desired effect. These filters feel good to use. Yes, you need to be careful as with any type of photography filter, but you don’t have to worry as much as when you’d use all glass square / rectangular ones. They’re light but don’t feel hollow. Their magnetic capabilities make them really easy to swap around when you’re out in the field. No more unscrewing and fumbling with filter threads on location. Just set your base ring to your lens, and from then on, it’s just magnets doing their magic.So, let’s dive into what this Freewell magnetic filter system review, and discover if they are actually worth your money. Video Review + Unboxing Consequently, we’ll need to judge this filter set on two aspects: the functionality of its magnetic attachment system, and the quality of its VND filters (and filters in general). What Do You Get? J. Matthew Gore We’ve also improved the lens cap. It’s now easier to remove, even when using a lens hood. We’ve introduced a convenient holder for the cap, making it a breeze to take it on and off your filter. Ladies and gents, I have some news for you. The Freewell magnetic filter system is officially on the market. Gone are the days of having to screw on your filters like a measly peasant.

I can see the benefits of convenience for such an attachment mechanism over screw in filters. I assume that they have been tested on lenses attached to bodies employing magnet IBIS technologies (as opposed to springs) and that on such bodies there is no magnetic field interference. Other filters are only regular ND which means they have just a single function as a plain ND4,” a Freewell representative tells PetaPixel. “Other systems use a single piece for the glass filter which has already been available in the industry for decades. The only thing unique about other similar products is that they are magnetic. Freewell filters are the world’s first magnetic VND that have a “seven plus one” feature set. Absolutely no other filter system on the market exists with such functionality and versatility.” Next step is choosing between neutral density (to darken exposure) or polarization (to remove reflections and increase clarity). Generally, a consistent color cast will disappear when you apply auto-white balance in camera or color correction in post. However, color casts may change the relationships between true white and colors similar to the cast and reduce contrast between them. Take this into consideration when shooting. J. Matthew Gore Conclusion and Recommendations Videographers and filmmakers should also appreciate the diffusion mist base filter. The filter’s 1/8 strength is just enough to create the desired effect without being too obvious (as it can be with stronger, 1/4 strength mist filters). Some videographers using cameras with super sharp digital sensors could very well leave this “mist” filter in their base ring at all times. PricingOverall the benefits of this magnetic system greatly outweigh my concerns of reliability which in my testing hasn't been an issue. Image Quality
