Freewell Gear have really been expanding their product range over the last year and along side the release of the DJI Mavic Air they have continued to release a range of products for this new model too including carry cases, device holders, individual ND filter and complete kits.
Today we are specifically looking at their All Day Filter pack for the Mavic Air, this pack contains 8 screw on filters that should pretty much cover most peoples needs.
This kit contains a Circular Polariser and 7 double sided multi coated filters in both ND and Polarised ND that should be sufficient even in the brightest conditions. Being extremely lightweight at 0.5g for the standard ND and 0.8g for the ND/PL.
Looking at the ND filters closely you will see that they are extremely well made. The glass is perfectly fitted with no signs of adhesive and both internally and externally the machining is precise with no signs of any imperfections. Externally you can see that the Freewell name and the ND rating are marked on opposite sides. To make fitting easier Freewell have also added grips around the outside edge of the filters.
Moving to the Polarised ND filters these are a little larger overall compared to the ND and have a separate rotating ring on the top. If you have not used Polarised filters before these have the additional ability to restrict light from specific directions depending on where the filter is set, this means you’re able to reduce glare from the sky or remove reflections from water. To set the polarisers position you simply turn the outer ring until you get the desired effect on your footage, this is easy to do on the ground before take off.
Here you can see the difference depending where you set the Polarising position
To fit you simply remove the existing ring from the Mavics camera, its worth noting that the Mavic Airs UV glass does not actually come off and you are simply removing a hollow outer ring, the filter then simply screws on in replacement onto the camera over the existing glass.
In my tests these filters from Freewell provided excellent performance and light cut with no noticeable colour shift. Here are some frame grabs showing both the filters affect on frame rate and footage, the top image is with no filter with a recorded video frame shown on the right. The second image is ND16 and the 3rd is ND32, you can see the ND16 has lowered the shutter speed to 200 and the ND32 has reduced it further down to 30. In these conditions the ideal filter would be somewhere between the two however in actual flight I found the ND16 actually got closer to the double the frame rate rule.
