DJI Ronin 4D Evaluate: A Cinema Digital camera System With No Equal

What does it take to make a digicam stand out? Some corporations go for specs, some go for seems, some go for versatility. DJI went for all three with the Ronin 4D.

Construct High quality and Design

The Ronin 4D combines a digicam and a gimbal into one package deal. In doing so, DJI is ready to make the rig extra light-weight, higher balanced, and provide improved stabilization and management. It’s constructed of carbon fiber and aluminum-magnesium alloy and general with the DJI 35mm f/2.8 lens mounted, I discovered it to be an acceptable quantity of weight to stability out stability with consolation.

Buttons and controls are laid out on the left aspect of the digicam in addition to on the monitor with the implied cause being the operator’s proper hand can be holding the highest deal with. The Ronin additionally comes with left and proper handgrips that function controls on every. There’s nothing low-cost feeling about these buttons and scrub wheels, and DJI nailed the tactile expertise all through the digicam. There are small, purposeful particulars discovered all over the place and it’s surprising that that is the corporate’s first go at something of this model.


The monitor is a 5.5-inch, 1,920 by 1,080-pixel touchscreen show with 1,000 nits of brightness. It’s an ideal measurement for a gimbal the place a giant, rotatable display is at all times useful for monitoring however there must be a stability with how a lot weight it provides and simply how a lot room it takes up. The image high quality seemed good from my expertise and it had the readability to have the ability to discern topic sharpness by eyeballing it.

The touchscreen responsiveness was on level, even with gloves. I did some taking pictures with the Ronin 4D when the temperature was within the 20-degree Fahrenheit vary and didn’t see any ghosting points or sluggish habits.

Video High quality

Able to taking pictures in 6K ProRes RAW and ProRes 422HQ as much as 60 frames per second and as much as 120 frames per second in 4K, the Ronin 4D is not any slouch in its video efficiency. At particular excessive body fee thresholds, the digicam will drive a 2.39:1 side ratio.

There are a few choices obtainable to take care of this, and contemplating this can be a 6K-capable digicam it’s truly not so dangerous. First, simply use the “cinematic” 2.39:1 side if it fits the challenge. That is the best, most evident possibility since it doesn’t matter what is shot it would match into any completed decision. The opposite possibility is to shoot 6K for a 4K challenge, or 6K and 4K for a 2K challenge. The two.39:1 side in 6K will match right into a extra customary 16:9 side in 4K and nonetheless have some wiggle room for body adjustment or cropping.

The Zenmuse X9-6K sports activities a full-frame sensor the corporate claims to have 14-plus stops of dynamic vary with twin native ISOs of 800 and 5,000. Pushing the D-log shade profiled information in modifying reveals its strengths, and I can verify pure gradations and the flexibility to save lots of appreciable info within the highlights and shadows.

As a gimbal-infused digicam setup meant to be handheld most of the time, sensor readout velocity and its rolling shutter results can come into play because the sensor whips about. Whereas I do see some bending of straight vertical traces, I must be aggressive as a way to make them seem and I discovered the outcomes to be about on par with every other cinema-style digicam I’ve used and not using a world shutter.


Whereas there are numerous attention-grabbing elements to the Ronin 4D, it’s the “4D” within the title that clearly DJI feels is a spotlight. Most gimbals compensate for pitch, roll, and yaw, nevertheless it’s the Ronin 4D that may compensate for up and down motion (Z-axis) as properly. This doesn’t must be lively on a regular basis, and there’s a devoted “4D” button on the aspect of the digicam for simple toggling.

In my testing, the 4D compensation is exceptional. I’m not a lot of a gimbal operator myself and even I may make comparatively clean photographs with out actually bringing my consideration to stability. The video under was taken once I was merely strolling round completely different terrain and particularly not attempting to deal with getting tremendous clear, secure photographs. Behind the digicam, I’m shifting about casually with principally one hand on the deal with. I needed to see if feasibly anybody may choose this digicam up and go.

To my eye, plus realizing simply how a lot I used to be hopping across the forest flooring and rocks and whatnot, the stabilization was the true deal. I believe to actually clear up these photographs, I’d fine-tune my panning settings within the digicam’s menu, however in any other case, the precise 4D Z-axis actions had been nullified.

With that in thoughts, I went slightly extra loopy and began working round with the digicam. Now, I’m in all probability the goofiest trying runner you’ll discover and nonetheless the footage seemed clean as may be. On the finish of the sequence proven under, I took it to the ultimate step and simply began shaking the digicam like a real maniac. There have been three levels of low, medium, and excessive depth shaking. Sure, you’ll be able to lastly see some shake within the clip, however on every other digicam and gimbal system, the image could be an absolute blur with nothing discernible within the body.


Autofocus is one other space the place DJI took a novel method. The Ronin 4D is supplied with a LiDAR system in a module that sits up close to the lens and calculates the space from a topic to the digicam’s sensor.

In follow, autofocus was hit or miss. The worst half stands out as the implementation the place it would soar very unnaturally to achieve new focus. I didn’t discover any menu setting obtainable to get it to sit back out for slower transitions. For non-human topics like my canine or simply strolling round in surroundings, the autofocus is unreliable and messy.

That stated, the autofocus actually shines in the case of filming folks. Whether or not I’m on the fringe of the body, distant, my again turned, strolling throughout, it doesn’t appear to matter and the Ronin 4D retains the autofocus locked on. One thing I wasn’t capable of take a look at was the way it handles a couple of individual within the body, and I’m wondering if it will be problematic with leaping round. I believe so, or not less than it’s probably harder to get it to decide on the fitting individual to observe. You may drag a field across the topic to trace on the touchscreen show, however from what I noticed that solely tells the gimbal what to observe and doesn’t have an effect on the autofocus concentrating on.

The LiDAR system advantages handbook focus as properly by reporting the space info in a graphical show. By matching what the digicam studies the main target distance of the lens is to the main target distance that the LiDAR is sensing, I’ve a really helpful assistive function. On the finish of the sequence under, I’m utilizing this depth metering choice to strive my finest at conserving handbook focus whereas watching a DJI Excessive-Vivid Distant Monitor.

A Beautiful Show of Technological Craftsmanship

I do know this digicam isn’t going to be for everybody and isn’t designed to be, however I believe it means one thing once I say that I want everybody may strive it out sooner or later as a result of they’ll get pleasure from it for what it manages to perform.

That leads me to consider perspective. Say you’re trying to get your first digicam rig and the Ronin 4D occurs to verify most of the containers. I believe for somebody like that who will get used to this digicam, going to every other digicam system sooner or later goes to be annoying. For that scenario, they’ll in all probability be dropping greater than they’d acquire in making the change. On the flip aspect, the remainder of us are in all probability trying on the Ronin 4D with our heads cocked as a result of it doesn’t observe the foundations of being a boxy cinema digicam that we restlessly construct upon.

Are There Alternate options?

The DJI Ronin 4D takes a very new method towards providing a full package deal of merchandise designed from the begin to praise and work with one another. The choice to this might be going the standard route in shopping for all the things independently — the digicam, the gimbal, the five-inch monitor, and so forth — and having slightly extra independence on the setup.

Actually although, there isn’t a package deal deal that works this properly collectively aside from what DJI has right here. It’s, for now, actually distinctive. Although it’s not low-cost at $11,499, I’ve to assume that anybody who makes an attempt to construct an analogous system a la carte goes to search out themselves spending not less than that a lot and none of these elements will work collectively fairly in addition to what DJI has within the 4D.

Ought to You Purchase It?

Sure. The DJI Ronin 4D is simply too distinctive and too properly designed to look previous. It’s not excellent in all areas on a regular basis, nevertheless it’s a package deal deal and one which has no competitor proper now. Even when there have been, I’ve a tough time imagining every other firm going as exhausting as DJI did for this one nor succeed almost as properly.
