DJI Ronin 4D Ronin 4D

With video quality in the 91st percentile and a built-in 4-axis gimbal, the Ronin 4D 8K delivers jaw-dropping footage. But the lowest user sentiment we've ever recorded (9th percentile) stems from a fatal flaw: focus assist and reliable autofocus vanish above 60fps. If you shoot at 120fps, you'll be manually focusing blind.

The DJI Ronin 4D 8K Combo Kit lands in the 91st percentile for video quality, putting it among the absolute best cinema cameras we've tested. It shoots 8K60 ProRes RAW, 4K120, and comes with a bright 5.5" touchscreen and a shockingly effective built-in 4-axis gimbal. But here's the catch: user sentiment sits at a brutal 9th percentile—one of the lowest we've ever seen—thanks to serious focusing headaches that undercut the otherwise incredible image.

This thing is a video beast. The 44.7MP full-frame sensor and ProRes RAW support let you capture 8K75 in 2.39:1 or 8K30 in 17:9 with ProRes 422 HQ, and 4K120 in 10-bit Log. In practice, that means you're getting cinema-grade detail and dynamic range in a highly integrated package. The 5.5" display is sharp and bright at 1000 nits, ranking well above average, and the modular design with LiDAR and remote control adds real on-set flexibility. The 4-axis gimbal stabilization is what sets this camera apart. While our stabilization metric only places it at the 32nd percentile (due to the unique nature of compared systems), the gimbal delivers shots so smooth you'd think you had a separate Ronin rig. The weak link is autofocus: it's below average at 34th percentile, and the real killer is that all focus assist tools vanish above 60fps. Manual focusing at 120fps becomes a guessing game, which is a huge letdown for a $10K cinema tool.

Prices for this kit vary wildly across vendors, from $9,999 to $13,583—a $3,584 spread. If you're set on buying, shop around to land that low end. For around ten grand, you're getting a camera that would cost far more to replicate with a separate cine body, gimbal, wireless follow focus, and monitor. But that value proposition only holds if you can live with the focusing limitations. Against a well-rigged Sony a1 II or Nikon Z9 with an external gimbal, the Ronin 4D is a pricier but far more streamlined solution.

Stack it up against the Sony Alpha a1 II or Nikon Z9, and the Ronin 4D is in a different conversation. Both those mirrorless flagships shoot 8K internally but need a gimbal and external recorder to match the DJI's ProRes RAW muscle—and still won't touch the integrated 4-axis stabilization. The Panasonic S5IIX offers stellar IBIS and 6K for a fraction of the price, but lacks internal RAW and the gimbal-grade smoothness. Where the Ronin 4D stumbles is autofocus: the Sony and Nikon, especially, run circles around its 34th percentile AF. If you need to pull focus reliably at high frame rates, those hybrids are far more forgiving.

If you rely on fast, dependable autofocus for event work or often shoot above 60fps, the Ronin 4D will frustrate you. The absence of focus assist at high frame rates and its 34th percentile AF performance mean you'll miss critical shots in dynamic environments. Also, if Netflix approval is a hard requirement for your deliverables or you need a lightweight handheld rig for all-day shooting, look at a fully rigged mirrorless instead—the 1450g body plus gimbal weight adds up fast.

The Ronin 4D 8K is a filmmaker's dream on paper, and when everything clicks, the footage is stunning. The integrated gimbal is a genuine innovation that makes it a one-of-a-kind cinema rig. But the missing focus assist above 60fps and rock-bottom user sentiment can't be ignored. This camera demands a crew that's ready to work around its quirks—pulling focus manually without peaking, and staying under 60fps when they need autofocus aids. If you can handle that, you'll love the image. If not, the frustration will outweigh the brilliance.
