DJI occasionally knocks us sideways with cutting-edge innovation à la the Ronin 4D, but it’s usually just refining existing products to stay ahead of rivals. That applies to the new RS4 and RS4 Pro gimbals, which boast multiple improvements over the previous RS3 models, particularly in the size and capacity of cameras they can support, but no new standout features.
However, the company also unveiled the Focus Pro, a new version of its LiDAR focus system that works either standalone or with the RS4 Pro. This product is more on the cutting-edge side, adding a host of new capabilities to the company’s gimbal and camera systems.
DJI RS4
The mainstream RS4 gimbal is largely the same as the last model, with a carrying capacity of 6.6 pounds (3kg) that accommodates most mirrorless cameras and a good load of accessories. However, the tilt axis has been extended 8.5mm compared to the RS 3, giving you more balancing space for longer lenses or front-heavy add-ons like ND filters. It also uses DJI’s latest 4th-gen stabilization algorithm for improved smoothness and control.
The RS4 can pair with the new Focus Pro Motor (more about that in a sec), allowing smooth focus and lens zoom adjustments at a speed 30 percent faster compared to the original DJI Focus Motor. As before, it uses dual-mode Bluetooth tech so you can pair with and control multiple cameras.
Another new feature is improved stability in vertical shooting, steadying jolts for the influencer crowd even when walking or running. The redesigned gimbal horizontal plates allows for “seamless transitions to vertical shooting,” the company said, allowing for more efficiency in video creation (to let you quickly get out an Insta Story while filming, for example).
As before, it comes with automatic gimbal locking and unlocking for ease of use, along with Teflon coatings on all three axes for smooth operation. A new joystick mode switch lets you change from zoom to gimbal control and the customizable trigger can quickly turn on the FPV mode.
The RS4 supports multiple accessories via the RSA communication port, including DJI’s RS Tethered Control Handle and third-party options (DJI has an SDK protocol for the RS family). IT also supports the new BG70 High-Capacity Battery Grip that extends runtime to 29.5 hours with a 2.5 hour charge time (compared to , while supporting power delivery to camera and USB-C accessories.
Finally, the RS4 supports DJI’s Ronin Image Transmitter, delivering live-action high-definition feeds to other crew members and allowing for remote-control (focus, etc.) capabilities.
DJI RS4 Pro
The RS4 Pro ups the carrying capacity to 10 pounds (4.5kg) as before, while adding side handles and extra mounting points for accessories. It adds a 20 percent motor torque boost to all axes (compared to the RS 3 Pro) to allow for more responsive tracking even with heavy cameras and accessories.
DJI also introduced a car mount mode, optimizing the stabilizer for vehicle shoots, while updating vertical shooting capability and improving axis locks. Like the RS4, it has DJI’s latest 4th-gen stabilization algorithm that’s particularly helpful for fast-moving scenes when carrying a heavy camera.
The primary new capability is functionality with the Focus Pro LiDAR and Focus Pro Motor system, giving cinematographers autofocus capability even with manual focus lenses. It also supports remote control and image transmission, “allowing for remote gimbal operation and intelligent focus assistance,” according to the company.
“In collaborative team shooting, the gimbal operator can control the RS 4 Pro gimbal through devices such as the DJI Master Wheels, DJI Ronin 4D Hand Grips, and DJI High-Bright Remote Monitor. Meanwhile, the focus puller can enable LiDAR Waveform on the High-Bright Remote Monitor for intelligent focus assistance, precisely controlling focus using the Focus Pro Hand Unit,” DJI says.
DJI Focus Pro
For creators and cinematographers, the Focus Pro is the most intriguing product in this release. It’s a LiDAR focus system consisting of the Focus Pro LiDAR unit, Focus Pro Grip, Focus Pro Motor and FIZ Hand Unit. It gives the operator autofocus capability even with manual lenses, or lets them focus manually via a real-time view from the LiDAR’s perspective.
The grip has a full-color touchscreen, 2.5-hour power supply, intuitive visual operation, auto-calibration and data storage for 15 lenses, along with Bluetooth capability for easy start/stop recording. The LiDAR, meanwhile, supports focus at up to 20 meters (three times more than before), and has an ultra-wide 70-degree view for focus. IT has 76,800 ranging points and a 30Hz refresh rate to minimize focus hunting and ensure reliable focus.
Autofocus includes AF subject recognition and tracking, adjustable focus speed and selectable focus area modes, much like a regular mirrorless AF system. The AMF (auto-manual focus) mode, meanwhile, allows for instant switching between manual and autofocus for tricky shooting scenarios. It also helps camera or focus operators by showing the LiDAR waveform. I tried something similar with the Ronin 4D, and while it takes a while to get used to, it’s very effective.
The FIZ Hand Unit allows full remote control over focus, iris and zoom for focus pullers. It uses stepless real-time damping for smooth control, while letting the focus puller be up to 160 meters away. Other features including faster motor speeds, 10ms latency and intuitive dial operation.
Price and availability
The DJI RS 4 is now available for purchase starting at $549 and includes one Gimbal, BG21 Battery Grip, USB-C Charging Cable, Lens-Fastening Support, Extended Grip/Tripod (Plastic), Quick-Release Plate, Multi-Camera Control Cable, and Screw Kit. You can also pick it up for $719 in a combo with a Briefcase Handle, Focus Pro Motor, Focus Pro Motor Rod Mount Kit, Focus Gear Strip, a second Multi-Camera Control Cable, and one Carrying Case. The RS 4 Pro, meanwhile, starts at $869 or $1,099 with the high-capacity battery grip, with the same range of accessories for each.
The Focus Pro creator combo (DJI Focus Pro LiDAR, DJI Focus Pro Grip, DJI Focus Pro Motor and DJI Focus Pro Carrying Case) is $999, or you can buy the All-in-One combo (with the FIZ Hand Unit as well) for $1,899. The RS BG70 high-capacity battery grip is sold for $149 by itself.
