The main improvements for video over the A1 include the improved IBIS (8.5 vs 5.5), stabilization modes, rear screen (resolution and functionality), AF performance, LUT support (importing function), high ISO performance, higher second-base ISO in S-Log3 (5000 vs 4000), and the new implementation of S-Log3 to match the Venice/Burano color space and detail (as a dedicated B-cam). Also, the 8K insect 🦋 stock footage business will never be the same!

This French technical review with available English CC compares the C400 with the C500 II, FX6, and RED KX. Considering the new triple-ISO, the C400 has better ISO performance than the C500 II. DR (14 stops usable in RAW 6K) and color fidelity ("Delta E" at two different exposure levels: lower score is better) are very similar between the two cameras. Unfortunately, there is no real-world comparison here, but at least you can get an idea of how the C400/C80 sensor should perform in challenging conditions.

Aside from a few action cams and a camcorder, let's remember Nikon's last dedicated video camera was released in 1982: Whatever they release that is not a mirrorless/hybrid will likely be under RED. If it does have 16-bit RAW (REDCODE), it will need to deal with the heat management and power requirements. Perhaps they could do this in a Z9-size body with the addition of active cooling. There is nothing smaller that could handle 16-bit RAW with current sensors, ASICs, batteries, and the rest.

I never stated that the R1 would be a better on-set cinema cam than the C80. I actually said the opposite way up there. I just think it could be an alternative for those also interested in the C80 (like me) who need something mobile. Then we had the discussion about why you would get an R1 over an R5 II, which I did not initiate. I only responded to the R5 fans (pun intended) with all those graphs and charts to suggest that the R5 II does not really improve on the highlight clipping problems I have with the R5C. The point here is that the 6K sensor in the C80/C400 is going to offer a substantial IQ improvement on all the R5 cameras, which really can't be compared with proper Cinema EOS. In the meantime, I've recently seen more RAW C80 footage and it is pretty awesome: The C80 also looks fantastic in XFAVC 10 bit. Here are some XFAVC files available for download: Despite the charts I posted above, in most scenarios the differences between the C80 and C400 will be minor. Perhaps you will see some differences in extreme low-light with noise in RAW LQ, but otherwise the C80 looks gorgeous overall. I don't use HFR much, so that C400 advantage doesn't worry me. In any case, RED and Sony should be scared.

Again, you like to put words in my mouth. I made no such "demands." I posted test results on the R5C, a camera I own and use. When it comes to C400, C80, and R1 comparisons, everything on this thread is speculation. Some are very offended that the R1 should be considered here or that it may turn out to be a better video hybrid than the the R5 cameras. That's not my problem.

I never stated otherwise. We need the R1 and its CRM files to make real assessments about how it performs in relation to the C80/C400. It could be that the faster sensor readout on the R1 undermines any DR advantages seen in all the C400 footage and tests. The AF circuitry is also different. But I can't imagine that Canon spent the last 2-3 years designing completely different and new 6K BSI sensors to be released at the same time in such low-volume cameras. Also, no one in his right mind who needs a proper cinema cam should go for the R1 over the C400, even if they share a similar sensor and image quality. It just becomes interesting when comparing the R1 with the C80, which is still using SD cards, and lacks the FF 6K 60p RAW, IBIS, and EVF. For those who need portability in the field, which is what the C80 is supposed to offer, the R1 is just another choice and obviously a better hybrid.

On Imatest results, the acceptable signal-to-noise ratio at .5 "Medium" will provide the usable DR. Otherwise, using your methodology of max DR, the R5C 8K RAW (16.1 stops) comes out way ahead of the R5 II 8K RAW (15.1 stops) when both are placed on a 4K timeline: There is no way you can recover the max DR (16.1 stops) on an R5C. So max DR is often pointless, except for camera marketing purposes. I would rate the R5C at about 11 stops, which is confirmed by the usable DR above (10.8). That would mean the R5 II (11.7) is giving us almost 1 stop more than the R5C when 8K RAW is placed on 4K timeline. However, by the same methodology, the R5 II has no advantage (both were about 11 stops) when looking at the 8K RAW source on an 8K timeline. I absolutely agree with the eye test and everyone should just go with that. As I stated above, it is obvious the R5 II has improved noise performance in the shadows, except at high ISOs where the R5C seems better. What I'm not seeing is any improvement in the highlight roll-off, which is a problem with the R5 cameras. The Sony A1 by comparison has better highlight roll-off than any R5 camera, including the R5 II. The new 6K sensor in the C80/C400 (and possibly in the R1) should demonstrate significant improvement in all these areas.

I have no intention of buying an R1. It's just an idea for the future. For VND, you shouldn't be getting any green shift. On the R5C, I use the Freewell V2 Hybrid VND/CPL (3-7 stop) and it is really impressive in preventing color shift. It is magnetic, easy to use, and comes with a nice case. You should try it.

Not really. It is difficult to recover gradations of tone and color that are not in the original RAW file. As I mentioned, I will need the CRM files to confirm. The R5 II and R1 have very different sensors that should produce visible differences in DR, RS, noise/texture, and color. Since the R1 sensor is likely a variant of the 6K sensor in the C400/C80, I would expect better performance for video than the R5 II's 10.9 stops of usable DR and 17ms rolling shutter in 8K mode (as demonstrated in the tests above).

In the following side-by-side comparison between the R1 and R5 II in RAW video, you can see the blown highlights in the R5 II when looking at the white beam above. That may be caused by a higher base ISO, but the overall DR does seem reduced here. In addition, the R1 retains rich and more accurate colors in RAW. It has better color and tonal separation, whereas the R5 II looks bland and overly magenta. These are just preliminary observations. I'm sure there will be proper tests when the R1 is released.

I am expecting a DR advantage for the R1 (owing to the larger pixel pitch and better signal-to-noise) as well as a significant improvement on rolling shutter over the R5 II's 17 ms in 8K mode, but we don't have the tests to prove it just yet. The R1 has a near global shutter sensor readout speed, so that may negatively affect DR. Based on what I have seen of the two cameras so far, I really prefer the look of the R1 sensor, which is likely shared in some way with the C400/C80. I'm also not a fan of the magenta bias I've seen in the R5 II footage, but that is just a personal preference. For the R5 II vs R5C, I mentioned that the former definitely has an advantage in the shadows: In my experience, NR works well on the R5C 8K when required, so the shadow noise has a solution. Unfortunately, the R5 II does not solve the problem with highlight roll-off. For everyday use, these cameras are nearly identical: G. Undone's Imatest numbers for 8K are also very close for usable DR (Medium). 11 stops on the R5C interpreted in CLOG3: 10.9 stops on the R5 II interpreted in CLOG2:

R5 II offers very little DR improvement on my R5C (and only in the shadows), whereas the the R1 looks like a significant improvement in both highlights and shadows. However, I will need to see more footage when the camera is released. FF 6K RAW is really the sweet spot for video. The EVF and AF on the R1 are also world class and there is no need to attach a fan/battery compartment to avoid overheating in our L.A. summers. Canon 1-series cameras are simply built to different standards in terms of weather sealing and durability. Unfortunately, there is no anamorphic de-squeeze on the R1 or R5 II, which is one of my favorite features on the R5C. With either of these cameras, I would need an external monitor. IBIS wobble is another problem that the R5C avoids, since it has no IBIS. Perhaps, there will be an R5C II, but I'm not hopeful.

So far on my R5C, I've shot everything 8K RAW LT and it looks great. Since it is 8K, the data rate is just over 1000 Mbps. I'm just concerned that the 640 Mbps data rate is very low on the C80. You can see the loss of detail in the CVP test of the different RAW variants in the C400 test. The drop off between ST and LQ is significant: 6K RAW LQ is the best available quality on the C80. While it is the obvious choice for taking on set (over a hybrid), it is a disappointment that they used SD cards and limited the 6K RAW to LQ and 30p. If on-set use is part of your requirement, I just think you are way better off with the C400. It has many advantages over the C80 at a $2500 premium. Then again, I still own the C500 and barely ever use it these days . . .

It will be interesting to see how the R1 compares with the C80 and C400. According to Canon, it is also rated to 16 stops of DR in video: https://www.newsshooter.com/2024/07/17/canon-flagship-eos-r1-announced/ The use of CFexpress Type B allows for much higher quality 6K RAW than the RAW LT found on the C80, which is also limited to 30p unlike the R1's 60p. The R1's Standard RAW is basically on par with the RAW HQ on the C400. The R1 will retail for $800 more than the C80, but that might be worth it. You lose the I/O, NDs, and cinema features (e.g., waveforms, anamorphic de-squeeze), but you gain better RAW quality, IBIS, AF, EVF, and hybrid usability.

You will have to wait for DSMC4, which could happen in 2025-26. Aside from high-end cinema cameras, I think the next logical step for RED after DSMC3 is to push into the mirrorless market, which is where all the action is. I would expect more RED features and branding on Nikon mirrorless cameras.
