DJI is adding a new tool for high-end video and cinema productions, the Ronin 4D camera. It builds on the company's Ronin gimbal family, a line that's already used by cinematographers, but instead of working with an Arri, Red, or similar movie camera, this one puts stabilizer and camera together in one package.

It includes a couple of firsts for DJI. The gimbal steadies the camera on four axes, not three. It adds the z-axis to the expected pitch, roll, and yaw correction. The integrated Zenmuse X9 camera is also new, and it's the first from DJI to include a full-frame sensor. There are two camera configurations available, one with a 6K sensor and a second with 8K support.

Both versions rely on LiDAR tech for autofocus, technology that DJI promises delivers speedy, accurate autofocus, even for low-light shots. The Zenmuse has a swappable lens mount with options available for DJI's DL series and Leica M lenses. Other manual lenses are compatible via adapters, and a waveform focus assist is available—it works with the LiDAR system, and offers the option to automatically pull focus when using geared manual lenses.

The video toolkit is as strong as you'd expect from a cinema camera. The X9 supports ProRes, ProRes Raw, as well as basic H.264 recording. The X9-6K camera supports 6K60 and 4K120, while the X9-8K can push up to 75fps at full resolution. CFExpress memory is supported, and there's a 1TB SSD option as well. The DJI PROSSD is an add-on option for the 6K camera, and is included with the 8K. Wireless video transmission is also available as an upgrade.

DJI is bringing the 6K version of the camera to market first, in December, for an hefty $7,199. The 8K edition will follow at a later, as yet undetermined date for $11,499.

My Experience

Images, and the devices that capture them, are my focus. I've covered cameras at PCMag for the past 14 years, which has given me a front row seat for the changeover from DSLRs to mirrorless cameras, the smartphone camera revolution, and the emergence of drones for aerial imaging. I have extensive experience with every major mirrorless and SLR system, and am also comfortable using point-and-shoot and action cameras. As a Part 107 Certified drone pilot, I’m licensed to fly unmanned aircraft systems (UAS) for commercial and editorial purposes, and am knowledgeable about federal rules and regulations regarding drones.

The Technology I Use

I use all of the major camera systems on a regular basis, swapping between Canon, Fujifilm, L-Mount, Micro Four Thirds, Nikon, and Sony systems. I still find time to use Leica M rangefinders and Pentax SLRs on occasion, too. I keep an iPhone 13 in my pocket for the rare occasions I'm not carrying a camera.

I'm not a brand-specific photographer. For product review photos, I swap between a Canon EOS R5 and a Sony a7R IV. I use Flashpoint and Godox TTL lights and Peak Design tripods, and I most often reach for a Think Tank or Peak Design backpack to carry equipment.

When it comes to computers, I'm an unapologetic Mac person and have been for the past 20 years. I write in Pages and use Numbers for spreadsheets. I currently swap between an Intel i9 MacBook Pro and an Apple Silicon Mac Studio for writing and use a calibrated BenQ 32.5-inch with the Studio for photo and video editing. I rely on a LaCie 6big RAID for media storage. I also keep a PC around for gaming, but please don't tell my Macs about it; they'll get jealous.

I split time between several different software apps depending on the type of editing I'm doing. For Raw image processing, Adobe Photoshop Lightroom Classic is my standard. I pair it with a LoupeDeck CT console to supplement my keyboard and trackpad, and I lean on RNI All Films 5 presets when I want to give an image a film look. I use Apple Final Cut Pro for video editing.

My first digital camera was the Canon PowerShot Elph S200, and my first DSLR was the Pentax *ist DL. I have a soft spot for antique film gear. I still use a 1950 vintage Rolleiflex Automat TLR and love trying mid-century Leica lenses on film and digital alike. I mainly use whatever's in front of me for review for digital snaps, but I pick up either my Leica M Typ 240 or Pentax K-3 III Monochrome when I want to step away from review work. In my downtime, I enjoy bird watching, reading, video games, and both good and bad movies, especially in the sci-fi and horror genres.
