A cinema camera that records 6K internal raw for $2,200 sounds like an easy call against a rival that costs more than double. The Nikon ZR undercuts the Sony FX5 so aggressively that price alone seems to settle the argument, until storage enters the picture and the math shifts.
Matt WhoisMatt Johnson puts the Nikon ZR head to head with the Sony FX5, and the split verdict is what makes it worth your time. Both cameras record raw video internally, a feature that only spread across the market after Nikon acquired RED and cleared the legal fog around compressed raw. The ZR gives you a buffet of raw options, including RED RAW, N-RAW, and ProRes RAW. The FX5 gives you exactly one, X-OCN. On paper, the Nikon looks generous, but Johnson shows why more choices don't automatically win.
Compression is the whole game. Nikon offers all those raw flavors with barely any compression, which means enormous files. Johnson loads a 1 TB CFexpress Type B card into the ZR, sets it to 6K at 60 fps, and gets 36 minutes before the card fills. The FX5, using X-OCN C1 and C2, records raw small enough to fit on a V60 SD card, and its files can run roughly four times smaller than the ZR's. There's a bit-depth gap too. The ZR records 12-bit raw while the FX5 hits 16-bit, though Johnson is careful to note that RED's logarithmic raw and Sony's linear raw land closer in real quality than the color-count numbers suggest.
Nikon takes real wins, and they're not throwaways. The ZR handles 32-bit float audio through the standard 3.5mm mic jack with no adapter, while the FX5 requires a separate XLR handle that costs hundreds more. The ZR shoots 6K to the FX5's 5K, gives you actual raw photo capability with a dedicated photo switch, and ran a long time in testing without a fan or overheating. The FX5 answers with a triple base ISO, 3:2 open-gate recording, dual card slots for backup, an optional EVF, and a grip Johnson clearly prefers. Both cameras tie on autofocus and on their oversized rear screens, with the FX5 borrowing the tilt-and-flip design from the a7R V.
The most useful takeaway here isn't which camera wins, it's how to read a camera's true cost. A body price is a down payment. Raw workflows carry a recurring tax in cards and drives that keeps charging you long after the purchase, and that tax scales with file size. This is why a spec sheet listing "6K raw" tells you almost nothing on its own. The codec and its compression decide whether you're buying a 1 TB card every few shoots or stretching an SD card you already own. If you shoot events where footage piles up fast, a body with efficient compression can quietly save you more than the sticker gap between two cameras. If you shoot short, controlled projects and archive selectively, big raw files hurt far less. Match the storage math to how much you actually record before you let the lower price decide for you.
There's one more layer Johnson leans on hard. Plenty of people don't want to shoot raw at all, and this is where he feels the FX5 pulls decisively ahead. Sony's XAVC codecs in S-Log3 look polished and easy to grade, and combined with stronger dynamic range, the FX5 delivers a usable image in nearly any format. The ZR's H.264 and H.265 feel more like an afterthought next to its gorgeous RED RAW output, which means you're realistically buying the Nikon to shoot raw specifically. Factor in the storage costs of that raw, and the FX5's price premium narrows more than the raw numbers imply.
Johnson still calls the ZR the better deal and a genuinely great way to get into full frame raw, while describing the FX5 as the more complete package with better ergonomics, low light, and codec flexibility. He reads the ZR as a strong version 1.0 and openly hopes for a Mark II that fixes the grip, the micro HDMI port, and the odd microSD second slot while holding the price.
