DJI Zenmuse X7 Review – Testing the New Drone Camera in the Field

This is a guest review by drone expert and cinema5D reader Chris Boyes from 5kdigitalfilm, who had a chance to work with DJI’s new high-end camera on a job. He created some beautiful imagery and made this DJI Zenmuse X7 review for you. Enjoy! (Intro by Sebastian Wöber)

DJI Zenmuse X7 Review

We have been using the DJI Inspire 2 and Zenmuse X5s professionally for the last nine months and regardless of much that I have read in the forums, ours has proved very reliable. Yes, the props are a bit loose and it’s irritating having to drive to get a connection to log in sometimes, but let’s not forget it’s a highly complicated and technologically advanced bit of kit that, for us, always delivered when it mattered.

I think many of us were excited after the press release revealed the specs for the Zenmuse X7. A few weeks after we had an offer for an ad job filming Tirol’s beautiful landscapes for the Cine Tirol Film Commission. For this project, DJI provided a sample of the DJI Zenmuse X7 along with a complete set of lenses, which led to this Zenmuse X7 review.

DJI Zenmuse X7 Review - Lens Assembly


We were running a Beta software from DJI on the Inspire 2, with 2 CrystalSky monitors and the latest firmware on everything else.

The test flight went well with everything more or less working as it should, we filmed a few minutes in a few different formats just to check we were up and running. We decided that 4K ProRes 4444XQ was the best option for the project.

Winter had arrived a month early making our story board obsolete and planning extremely difficult as our primary brief was to capture the Autumn/Winter transition in the mountains.

Shooting in Difficult Conditions

From the next morning on, we went out daily, battling the cold wind and snow waiting for a moment where the clouds parted to try and catch some colour before the landscape turned monochrome.

We worked in very difficult conditions with extreme temperatures of sometimes down to -15°C, high altitudes of up to 3300m as well as strong winds. We had to keep batteries in our pockets and even hover 1m over ground to heat them up quick enough as to not miss a shot. The DJI Inspire 2 was so solid, I thought more than once that it would never come home. But it did. Again, and again.

DJI Zenmuse X7 Review - Crystalsky Monitor

The DJI Zenmuse X7 felt great in the air, the gimbal was smooth, and operation over CrystalSky reactive. Lens changes were a breeze and restart occurred immediately, which in these harsh conditions was a godsend.

We filmed mostly landscapes in early morning or late evening, I found my 1.2 & 1.5 ND filters that I used on the x5s had a tendency to be a bit much. ND 8 seemed to keep me where I wanted to be aperture wise.

Filming mainly big panoramas the camera performed well at its native ISO 400 and open to about f5,6-f8. On this project, apart from a few shots closer to the ground, we didn’t really benefit from the shallow depth of field obtainable from the larger sensor.

Images From the Zenmuse X7

I noticed that monitoring exposure of areas with brightly lit snow was causing me some headaches, as my CrystalSky was often blown out even though my histogram told me I was safe. Later, the results seemed to be somewhere in the middle. Some of the snow in the bright sunshine was blown out, which seemed to be some kind of firmware issue that I soon had to get used to.

The images are not over sharpened off the sensor and for some uses they may be a bit soft. Some may worry that the lenses do not perform well, but if you look at the image in a proper post environment you can see that processing off the sensor seems to be the reason, as it is uniform across all material.

DJI Zenmuse X7 Review - Flying

We shot two sequences at dusk: it was very dark and I found myself quickly pushing the ISO to 1600 which is the max in EI mode. The low-light performance is inhibited by the slow lenses and might in comparisons or charts not be outstanding. However, in the grade and handled professionally, the images came up great and looked organic and natural.

The DJI Zenmuse X7 does have much better highlight roll-off than the DJI Zenmuse X5S. This was evident when shooting against the sun. An improved dynamic range was also noticeable in the material, but in order to get the best out of both of these, correct exposure was critical and, in my opinion, could only be achieved after more experience with the camera.

File Handling & Post Production

We have used the X5s and inspire 2 on quite a few high-end jobs, and the amount of Raw we have actually shot is percentage wise quite low.

Is this likely to change with the X7? I don’t think so.

At the end of the day running out of media is just another reason to have to come down and land.

ProRes 4444XQ is good enough for most situations unless you have extreme lighting/contrast problems or your shot will have heavy VFX or will be used for background replacement.

With one 480GB SSD we had over 30 mins of 4444 XQ footage which was more than enough for one location, meaning we rarely had to change SSD´s in the field.

We edited the ProRes files natively on a windows based high end machine running the latest Adobe software. We use a powerful  i7-6900 with 64GB Ram and multiple m.2 SSD drives along with two fast 4TB spinners in a Raid 0 for footage playback.

We can edit and playback the ProRes 4444 D-log footage in full res with effects and a basic grade without issues, which results in a very pleasing straight forward editing experience. When locked we play out a XML/EDL and the footage was send for grading in Resolve.

The 6K RAW DNG feature with the X7 is a nice and useful addition, but if you are not being rung up regularly by Hollywood or BMW then the chances of you really needing it are small.


My personal conclusion to this Zenmuse X7 review is this: the DJI Zenmuse X7 is a great camera that produces great images in the right hands. It’s not as plug-and-play as the X5s, and you have to get to know it and get a feeling for its strengths.

I have always been someone who prefers to look subjectively at the picture over graphs and figures. And to me, the X7 has a very cinematic image that we have never seen from a drone camera before. It is obviously designed to fit into a high-end production environment and deserves proper handling in post. Exposure is more critical especially in bright scenes like sunlit snow, and it seems that the Log footage from the X7 likes to be exposed a tick under what I am used too from shooting different logs.

There will always be those moments where you just don’t have much light – for these moments I would like to see at least a couple of faster lenses become available in the future.

If you shoot aerials professionally and already own the DJI Inspire 2, then it makes sense to invest in this small but powerful bit of technology.

We hope you enjoyed this DJI Zenmuse X7 review. Have you worked with DJI’s new high-end camera yourself? Share your experience in the comments.

Hi Chris,

Thank you for this informative review! Been using the X5s on my I2 over the last year, very happy with it but as you said the highlight rolloff isn’t the smoothest. Glad to hear that has been improved.

Also I am very curious about your “windows based high end machine”. Would appreciate to know more about its components as we plan to put together a new system here soon.

Thanks and best regards

How did you guys go flying at that altitude? did you use the standard props or have to change them to get more lift? also how did you edit prores on your windows machine?

We often started very high (above 3000M ) and we used the High Alltitude props from DJI that work until 5000M. You can edit ProRes on Windows without problems with the new Adobe creative suite.

Hi there, great review! thanks!
I have some questions about X7 workflow, if you can help me I really appreciate your advises.

DJI says they are working on pro edit and color correction platforms to include their own Gamma Source and Color Space.

In a post of Sebastian here about X5, he says BMD is a closer option to pickup a reference. Is that applicable to X7?

I always try to use a X-Rite Color Checker Video Passport shot and the DV Resolve tool as a start point with a correct colors. But it seems does’t work correctly with Cinema DNG from X7. Without any info of camera source is difficult to know if the process is correct and colors don’t looks accurate.

Other question is about EI (on)is the native iso 400? So is better to work in 400 than 100 or 200? So ND8 is absolutely basic.

The last question is about D-log in DNG. If the raw files are raw, they don’t have any curve applied? But EI on looks like D-log always (ultra flat). Is posible to add a LUT in a CristalSky monitor to show a closer image to director / client? or just to see something… is a real challenge to expose correctly in EI mode D-log.

Thanks i advance for take a moment to read my questions and cheers for your impressive footage.

Hi Guido,
It is indeed better to try and keep the X7 at ISO 400 if possible, especially if you have enough light, just adjust with the correct ND. If you are shooting in low light then you will have to push the ISO. Don’t worry, 1600 does grade up well.
I would not use the monitor alone to expose correctly, I have found the colour waveform in conjunction with the Histogram the only way to expose correctly and even then somehow it doesn’t feel 100% reliable in all conditions and camera settings. This is what I meant about getting a feel with the camera to get the best result.
Regarding your colour space question and correct colour representation, I am not a professional colourist and my knowledge is limited in this. Resolve is still the best grading option in conjunction with proper project settings and a calibrated monitor, The X7 has its own colour space but is not that far away from that of the alexa. With this project our colourist had little problems with a workflow integration in Resolve.
Hope it helps

Hi Chris, thanks for your quickly answer! I always use Histogram and Waveform to expose, but as you say, even with those tools some exposures were not really accurate. If your colorist would want to share his experience with X7 footage in Danvinci will be awesome… just a couple of trips will be more than enough… Thanks in advance, and congrats again for your work.
