Contrary to regular polarizers, the CPL has no moving parts. It rotates simply by moving on the adapter. This does generate a small friction noise. Anyone who needs neutral density filters will enjoy using the Freewell Magnetized VND system, but run-and-gun hybrid shooters using consumer DSLR and mirrorless cameras should love it. You may shoot photos one minute, flip the camera to video mode, throw on a variable ND to control shutter speed, and keep going. For polarization, do not add a filter to the base ring. If one has been inserted, remove it. Next, flip a “VND” filter over to its “CPL” side, then attach magnetically. CPL filters don’t require alignment, and can rotate a full 360 degrees without hard stops.

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 Screw the magnetic VND Base onto your lens and you've got 1 f-stop as standard (which can be removed –more on that in a sec). Now you can snap on a magnetic 2-5 stop filter, or a 6-9 stop filter –both of which have hard stops, despite being magnetic, which helps prevent the dreaded "X" pattern. Like the Freewell Magnetic ND filter, the polarizer also had a green hue to it; admittedly less noticeable than the 10 stop ND. Performance wise, it did exactly as it should. Cut glare, enhanced colour and balanced exposure with no loss in image quality.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 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.

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. 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). As explained earlier, both the 2-5 stop VND and 6-9 stop VND may be used as circular polarizers when flipped over (and the base ring filter is removed). Circular polarizers improve clarity, increase saturation, and bring highlights under control. They are frequently used in landscape photography to remove reflections and punch-up color and clarity, though they can of course be used when shooting video as well for a similar effect.

Next step is choosing between neutral density (to darken exposure) or polarization (to remove reflections and increase clarity). And my testing showed that these types of artifacts occur reliably with ALL of my VND filters. I shot this scene, first with no filter: J. Matthew Gore 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. 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.

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. There’s always a possibility that adding a couple pieces of flat glass in front of your expensive optics will degrade your resolution, but I didn’t find that to be the case with these filters. Having tested on my 42 megapixel A7RIII and some of my sharpest lenses, there was no visible loss in resolution in the center or edges of the frame when using the Freewell filters compared to test shots with no filters. Cross Polarization Problems Freewell says that its new system will be more convenient than others on the market, as shooters would only need to carry the two filters with them when traveling, and would still have the capability to capture images using ND stops from two to nine as well as having access to an integrated Circular Polarizer (CPL) and the “Glow Mist” bonus filter for creative applications. Like other magnetized filters, the speed at which these filters are attached and detached from a lens is fantastic. Each filter rotates nearly as smooth as a threaded filter, and the hard stops effectively prevent the VNDs from being overturned in either direction. When flipped over, the CPL filters rotate smoothly and easily. The filter is basically a stationary magnet - like a bunch of bar magnets sitting on a table. I don't expect there is much impact on the magnetic actuators (which are magnetic motors) used in IBIS to move the sensor. Some of Fuji's best lenses use linear magnetic motors in AF - for example the Fuji X 50-140 f2.8 and the 90 f2. There is no evidence of any interference with IBIS and those two lenses so I doubt if small would cause any issues.Thus far in my experience, I have not had any issues with the filters falling off in standard use. That can be walking on a trail with my camera above my shoulder, moving with my camera in hand filming a shot, or even running around a bit. The filters are quite secure because they are machined well to fit within the ring that's attached to the lens. Thus not only are the magnets holding the filter in but the friction caused by the precision of the manufacturer helps keep them secure. They are also light so it would require a large impact for them to detach. I haven't been able to get them to come off in the field or in testing. We’ve extensively tested these filters and found no issues when using them at various focal lengths. Whether you’re shooting at 16 millimeters on a full-frame camera like the Sony A7 Mark IV or Sony ZV1 with the 16-35 GM lens, the M2 filters deliver exceptional performance.
