Sorry I don't see why it can't be discussed? There is an actual thread for it. This one!

I sold my A7S III and got the A7 IV instead. For me it has a bit more mojo. Colours, and the new sensor at 30mp. Can shoot S35 and S16mm crops without killing the image quality. 10bit, better codecs than A7R IV. Low light pretty alright, at the ISOs I need it, but not A7S III level. I am curious to compare it to my S1 next and see which wins the image quality battle in video mode. There are a LOT of variables though which makes these things a bit more tricky than in GH2 vs 5D Mark II days

And I have the perfect place to discuss it 😉

Filmic Pro is bettered by mcpro24fps on Android in my opinion. But neither are the same proposition as Motion Cam as neither shoot raw video, which is its own thing entirely. The way the image looks, the way it bypasses the phone's processing, the way you grade it, is all totally unique to raw.

9mm F1.9 prime on Super 16mm is considered a decent lens. That's what the 12 Ultra has. The telephoto has a deep DOF, which is quite useful actually as you can get a lot in focus whereas 135mm on full frame, it is more challenging to not just see the subject and nothing else. At closer focus distances you have a very shallow DOF regardless on both of these lenses. You can also buy a DOF adapter and use DSLR lenses on it.

Sensors in smartphones are getting larger. Much larger. The progress in the last 7 years is remarkable (as my chart above shows). Smartphones have caught up and surpassed Super 16mm. Is Super 35mm next? New blog post: https://www.eoshd.com/news/smartphones-and-their-growing-threat-to-mirrorless-cameras-2022-edition/

Maybe it is time to forgive the EOS R5. The inanimate object that is. Not the decision makers behind the omnishambles that has been the last 2 years of unreliable firmware.

The results seem to show the image is identical on both cameras, but the EOS R5 is cheaper, has IBIS and better AF, also boots up quicker. They didn't test the overheating though?

Canon LOG showing an advantage here for me. Less noisy than Canon RAW and the GH6. Falls apart much later than N-LOG. They should have tested V-LOG on the S1 though as that is the budget full frame king for dynamic range.

It was all a fake limit!!

You must have been doing very light use and very short shoots in those modes, especially 4K HQ. The question is why didn't the camera perform like this in the first place 2 years ago? Why only fix it now? 2 years!

Eh? Where did I say it was "burning hot"? There are two separate discussions going on here. What type of overheating do you still think is the problem? Do you really think to avoid skin burns the camera needs 1 hour cooling off timer set in firmware plus arbitrary timers for 2 years upon release, then quietly removed with no explanation? First discussion is about what the camera hardware is capable of. The hardware we pay for should be fully usable. Are the operating temps of the CPU and image sensor ok under sustained load. As you see from your GPU or CPU these peak temps are reached within minutes, then stabilise. Is the same with the EOS R5. The temps stabilise and the alloy housing acts as a passive cooler to dissipate the heat to the air. Second discussion is the external temp in contact with skin and how hot is too hot or against consumer regulations and whether it can cause skin burns. If Canon is trying to avoid this, then why remove the limitation now? Did the rules change? I don't think so somehow. Then there is the related discussion of Canon segmenting the market and whether they wanted EOS R5 to be used in place of R5C and C70 for pro video production. All three of these were planned at same time with staggered release schedule. What capabilities are fully reliable on which models is a question of firmware not just hardware. So to answer discussion 1 - We proved way back in 2020 that the EOS R5 hardware was capable of running for long periods even in 8K with the EXIF temps never going above 65c and the battery pull + screw in the battery door trick was possible to reset the 'overheating' timer counting down in firmware. It was capable of restarting a recording immediately - but remember the old firmware had a lengthy 45 minute to an hour long 'cooling off period' which was clearly bullshit because it didn't even take into account actual temperature sensors in the camera. For example the camera being in a fridge recording 8K where it would cool to room temp within a couple of minutes after stopping. It still had that arbitrary timer blocking you from the features and not allowing the use of the hardware you paid for to the full potential. I was contacted by a class action lawyer in the US during these discoveries, and the whole thing was talk of the town. Canon were really on the back foot PR wise. All their own fault. They had created the perception of an unreliable but expensive flagship camera, and that their new hardware was overheating. So rather than recall it and change the firmware, or even just apologise to their users who had spent the money on a defective cripple hammered camera, they enlisted their client journalists to say nice things about it and brought out a faux-fix firmware update that did barely anything. So that was the situation for EOS R5 owners for 2 years until this complete U-turn last week. I don't. I have no use whatsoever for "unlimited" recording times. I just want normal predictable behaviour from a camera especially for £4000. 30 min limit is fine by me, I am not an event shooter. Remember how severe the problems were with the original EOS R5 firmware - you could be in the menus or just shooting a few stills and an hour later the camera would be locking you out of the high quality 4K mode and 8K. So by my standards I only have to be able to use the camera normally without being blocked by fake timers. I kept saying all along after the magic screw trick, it was a firmware restriction, not real overheating. Nobody would listen. Even Magic Lantern were saying it. Nobody listened to them either. Now the lifting of the firmware timers proves it. But still people's minds don't change. All I can say is I can explain it to you, but I can't understand it for you.

Who said anything about unlimited recording times? It was never an expectation of anyone about rolling unlimited number of hours in 8K. For those with short memories - We were sold a camera 2 years ago which was borderline unusable, shutting down from sitting idle in the menus, because of a badly implemented fake cripple hammer timer. There should have been a class action lawsuit brought. Canon soon realised they had a PR disaster on their hands so rolled out a firmware update and got all their client journalists to hype it up. That update did very little to improve recording times. We had been mis-sold and mislead into buying a camera that was advertised to do professional 8K and 4K video at highest quality when it couldn't even get through 20 minutes of sitting idle on set or an hour of light stills use before blocking you out of major headline features you paid for. Then to make it worse they refused to apologise, and left it out there software-crippled for 2 years before fixing it. But yeah you cannot expect anything more for your $4000... whatever Doug.

I am not sure what you know about electronics but warm to the touch is not classed as overheating. Have you ever looked at your PC CPU temps?

First test done. Went to 29m59sec maximum continuous recording length for 4K HQ with no issues whatsoever. Could start another clip straight after. No overheating warning. Camera body feels very hot all over, makes a nice hand warmer.

Well since it is 35 degrees C in Berlin today I decided to do a quick test. Put it in 4K HQ mode (8K sensor readout) and record until card fills up. I'll let you know what happens. (Don't expect any melting! The magic screw trick showed it could go for hours virtually non-stop shot after shot in 8K!) Of course the client reviewers will all now be out praising Canon for fixing the non-existent problem they tried to cover up.

Probably shooting in 1080p 😂

Does this mean I finally get to retire my Magic Screw? https://www.eoshd.com/news/2-years-later-canon-quietly-removes-fake-overheating-limits-of-eos-r5-in-firmware-update/

It all goes to prove our original point that it was a purposeful software limitation, and that you were not allowed to use the full capabilities of the hardware you just paid £4000 for. It should have been a class action lawsuit and maybe Canon knows it, which is why this u-turn has happened. At least we don't have to do the card trick now. I currently have an EOS R5 because I'm a hypocrite. So I'll see if it can go the full 2 hours of 8K without the card pull, and report back.

So it was a fake timer then.

By new do you mean the 2021 update? The latest one doesn't change anything to do with overheating. https://www.canon.co.uk/support/consumer_products/products/cameras/digital_slr/eos-r5.html?type=firmware&firmwaredetailid=tcm:14-2185943&os=macos 10.15 (catalina)&language=
