Seven days of nonstop recording is the kind of claim that usually gets a footnote. Camera manufacturers quote "continuous recording time" on a spec sheet, everyone nods, and then the real number turns out to be "about an hour if you don't push it." So when Fujiya Camera announced a 168-hour challenge with Canon and Nextorage — a full week of the Canon EOS C50 rolling without being switched off — my first thought was that this is a stunt. The second thought was better: it's the exact question nobody answers properly.
The camera gets plugged into mains power and left alone in a Tokyo storefront, recording to Nextorage cards, with the whole thing streamed on YouTube from November 8 at 5pm JST to November 15 at 5pm JST. Canon and Nextorage are co-running it. Fujiya Camera's own post confirms the dates and that it'll be livestreamed from the store's video hall during the period, with a message board for visitors.
What Canon actually promises on paper
Before you get excited, the spec sheet is where this either looks plausible or doesn't. Canon's Japanese product page for the EOS C50 lists a battery life table that makes the challenge's difficulty obvious. Recording full-frame 3:2 Cinema RAW Light at 6960x4640 and 29.97p draws 9.7W and runs about 90 minutes on an LP-E6P battery. 4K 59.94p in XF-AVC pulls 13.6W and gives roughly 60 minutes. 7K XF-HEVC S at 29.97p sits at 12.0W for about 70 minutes.
That's the number I keep coming back to. A single battery gets you roughly an hour and a half at most, and the way Canon phrases it is 連続撮影時間 — approximate continuous shooting time, with a footnote that the figures are estimates. So the C50 has no battery-only path to a week. It's running on external power: Canon lists the PD-E2 USB-C power adapter and the DR-E6 P or DR-E6 C DC coupler as operating power sources.
Which means the honest framing of this challenge isn't "can a camera record for 168 hours." It's "can a camera, a card, and a power setup keep a sensor alive and files writing for 168 hours." That's a much more useful question, and it's also a harder one to fake, because a thermal failure or a dropped write shows up on the livestream within minutes.
The parts that actually have to survive
Canon's own press release from September 2025 is where the answer to "but won't it overheat" lives. In the Japanese release, Canon attributes stable continuous shooting to a large internal fan: 大型ファンの搭載によって熱による影響を低減し、安定した連続撮影が可能です — the mounting of a large fan reduces the effects of heat and enables stable continuous shooting. That's the design decision that makes a week plausible. It's not a software trick; it's a fan in a body that weighs about 670g on its own.
Canon's spec page lists 15+ stops of dynamic range at full-frame and 16 stops in Super 35 crop, a 7K full-frame sensor with about 34.2 megapixels total and up to about 32.4 megapixels effective, and Dual Base ISO of 800 and 6400 in Canon Log 2 and Canon Log 3. Recording media is CFexpress plus SD. The camera weighs roughly 142 x 88 x 95 mm, and with the handle unit, mic holder, LP-E6P battery and cards fitted it comes to about 1120g.
That's a compact body doing the work of a much larger rig, and Canon's press release also notes it's the first Cinema EOS camera with full-frame 3:2 open gate.
The cards are doing their own stress test
Nextorage isn't just lending a logo to this. Two of its products are in the loop: the CFexpress 4.0 NX-B3AE 1000GB and the new NX-F2AE 1TB SDXC UHS-II card. These are the two very different limits the C50 has to work inside — a primary high-bitrate slot and a secondary one.
Nextorage's own spec page for the NX-B3AE lists a 1000GB capacity, PCIe 4.0 x 2 with NVMe 1.4, 3D TLC NAND, and a VPG400 guarantee. Read speed on the 1000GB model is 3,900 MB/s, write speed 3,600 MB/s, and the minimum sustained write speed is 1,700 MB/s. Operating temperature runs from -12°C to 72°C, which is worth noting given the fan and the week-long burn-in.
The SD side, the NX-F2AE, is the new one. Nextorage's product page lists 256GB, 512GB and 1TB, UHS-II with V90 video speed class, 3D TLC NAND, and both read and write speeds at 300 MB/s. The V90 rating guarantees a minimum sustained write of 90 MB/s. It passes seven durability tests including drop from 4.9 feet, 10,000-plus connector mating cycles and x-ray exposure to ISO 7816-1.
What would actually end the run
Here's where I have to be honest about what I don't know. Nobody has published the recording mode, frame rate or codec the C50 will be locked into for the week, and I don't want to guess at it. If they run 7K Cinema RAW Light at 29.97p, the maths is straightforward and brutal. A single 1TB card at a minimum sustained 1,700 MB/s write on the CFexpress side works out to roughly 10 minutes of 7K RAW per gigabyte if you stay in sustained write territory — which means the card array fills constantly and the run depends on the camera rolling files or overwriting, not on one card holding the week.
That's exactly the point of streaming it live. If a card drops a write or the camera thermal-throttles, you'll see it on the timeline, not in a press release six weeks later.
Why I care about this more than another launch
My GH7 has a fan too — Panasonic put the same active cooling in the GH6 and kept it for the GH7 — so the cooling claim isn't alien to me. What I haven't done is run one for a week. What I can say is that the number I care about on any camera I use is how long it keeps going before something gives out.
The thing that makes the C50 interesting is that Canon didn't just spec a fan and hope. They published a power table, a weight, and a dynamic range figure, and then a partner is putting a public timer on it for a week with the recording live. That's a different relationship between a manufacturer and a test than the usual launch-day round where the camera gets handed to a reviewer for an afternoon.
Canon's own claim in the September 2025 release is that the large fan enables stable continuous shooting. A week of continuous shooting is the strongest possible version of that claim, and the livestream means nobody has to take anyone's word for it. If it holds, the C50 has a durability story you can watch happen. If it doesn't, you'll have watched it fail in real time too — which is somehow more useful to anyone deciding where to spend their budget.
I'll be watching the Nov 8 start. The question I actually want answered isn't "can it record for 168 hours." It's whether the fan, the cards and the power delivery hold steady, or whether one of them gives out on day two and nobody says why.
