The DJI Inspire 1 is an incredible drone. In my tests and comparison of the X3, X5 and X5R cameras on the DJI Inspire 1 Pro I found that especially the Zenmuse X5R RAW camera delivers amazing images in 4K. But what about X5 ND filtration? On sunny days just closing the iris is not enough. So which is the best ND Filter for the DJI Zenmuse X5 and Zenmuse X5R cameras used on the DJI Inspire drone and DJI Osmo handheld gimbal? The Best DJI X5 ND Filter I found 5 6 different ND filters I could test both with the DJI Inspire 1 RAW and with the DJI Osmo RAW and compared them to each other that is both compatible withe the Zenmuse X5 and the Zenmuse X5R camera. First I compared the filters in the field under varying light conditions, then I did another comparison in our test lab. Check out the video to see the results. Here’s an overview of the different filters I tested and their properties explained. In the conclusion I will summarize my findings and recommendations. Polraoid VariND Weight: 15g ND filtration: 1-8 stops Weight balancing: filter, extension ring and 49mm fotasy lens hood (EU: Link) The Polaroid VariND is the most affordable of all the filters. It performed well, just had a slight orange tint. There are no hard stops, so it is not as convenient to use as the B+W. In order to be ok with gimbal weight you should use an extension ring and 49mm lens hood. The original DJI lens hood can not be used when this filter is on. The filter has no IR cut. US: BUY HERE EU: BUY HERE B+W XS-Pro MRC VariND Weight: 26g ND filtration: 1-5 stops Weight balancing: filter and 49mm fotasy lens hood (EU: Link) The B+W XS-Pro MRC VariND is a lot more expensive than the Polaroid, but build quality is excellent, it has hard stops and it looks quite neutral with a slight orange shift similar to the Polaroid. In order to be ok with gimbal weight you should use 49mm lens hood. The original DJI lens hood can not be used when this filter is on. The filter has no IR cut. US: BUY HERE EU: BUY HERE Heliopan VariND Weight: 49g ND filtration: 1-6 stops Weight balancing: Too heavy. Filter is not recommeneded. The Heliopan VariND feels like a solid product. It has hard stops and accurate markings and the image looks very neutral. Only at the far end I noticed an ND cross, so the ND filtration was not even. Unfortunately this filter is too heavy as an X5 ND or X5R ND. The filter has no IR cut. BUY HERE Tiffen XLE Series Intermediate 3.0 IRND Weight: 13g ND filtration: 10 stops Weight balancing: filter, DJI weight ring, and 46mm fotasy lens hood The Tiffen XLE Intermediate IRND filters 10 stops of light and has an IR cut built in. This was too much even for a sunny day and the IR cut turned my image green to counter magenta shift. The result was not neutral, so this option is not for me. BUY HERE Tiffen XLE Series Premiere IRND 3.0 Hot Mirror Weight: 13g ND filtration: 10 stops Also available in: Weight balancing: filter, DJI weight ring, and 46mm fotasy lens hood Just like the intermediate, this Tiffen XLE Hot Mirror IRND filters 10 stops of light. Too much exposure reduction for my tastes and the IR cut turned my image green. I was not happy with the result. If you need a good IR cut filter this Hot Mirror seems better suited than the intermediate option though. BUY HERE Formatt Hitech Firecrest IRND 1.5 Weight: 8g ND filtration: 5 stops Also available in: 1 stop, 2 stops, 3 stops, 4 stops, 6 stops, 7 stops, 8 stops, 9 stops, 10 stops Weight balancing: filter, DJI weight ring, and 46mm fotasy lens hood Just like the two Tiffen filters, this Formatt Hitech Firecrest filter has no variable ND functionality. It filters 5 stops of light and according to the manufacturer there is also an Infrared filtration built in. The image was very neutral and had a slight blue shift that I liked. It is the lightest of all the filters tested and not too expensive. US: BUY HERE EU: BUY HERE Conclusion For me the Formatt Hitech Firecrest IRND 1.5 was the ideal filter for sunny shoots. The neutral image looks clean, it is light and affordable and even has some IR reduction, though I did not seem to need that when testing the other filters. As a VariND the B+W seemed like the best option. Especially for the DJI Osmo as an X5 ND it would be ideal with hard stops and a clean image. As a budget option the Polraoid would also do the job, but another adapter ring is needed to balance it properly. I hope this review was helpful for you. If it was please consider buying your gear through our recommended retailer’s links. And if you worked with any of the filters or other X5 ND filters please let me know about your experience in the comments.Read more

Upgraded from your mirrorless camera to a RED Raven, but still frustrated with up front ND filtration? KipperTie may have the answer with their 6 piece drop in rear ND filters. KipperTie first entered the filtration scene with their Infrared and Soft Diffusion OPLFs (optical low pass filter) for the RED Epic. They’ve continued their venture into ND filtration, this time specifically for the RED Raven. Unlike conventional Neutral Density filtration, the KipperTie Raven Internal NDs are drop in filters that sit between the cameras sensor and back of the lens. A simple grip tool is supplied that holds the filter tight until you release upon insertion of the camera. A neoprene edge ensures a snug fit around the sensor housing without damaging any part of the camera. Of course, adding any amount of glass between the sensor and lens is going to affect your focal distance. KipperTie therefore supply a set of self adhesive shims that sit around the contact point of the lens to ensure focus markings remain accurate. Rear filtration can be great for alleviating the need to add ND on the front by means of a mattebox or screw on filter. This is great if you are running about and changing lenses often, or need to save weight and could do without a cumbersome mattebox, making it perfect for drone use. If you do want to change the amount of ND, this kit comes in a set of 6: ND 0.6, 0.9, 1.2, 1.5, 1.8 2.1 are all included, meaning you have a range of 2 to 7 stops neutral density. I can see this workflow working well in addition to up front filtration. Proper filters are expensive: a set of 5.65″ Firecrest 1-3 stop filters are over $1200 for example. On a bright sunny day, you’d need a 4-6 stop kit too, therefore doubling your investment. Throw a KipperTie drop filter in the back instead, and you’ll be able to moderate fine exposure with your 1-3 stop front filters once again. The 6 set of KipperTie drop in ND filters comes with 6 shims, insertion tool and custom foam hard case, retailing for £460+VAT.Read more
