EOS R5 Overheating Issues - EOS R6 No Dual Card Video Recording

[kimbulford]

Multiple reports are coming in that the EOS R5 has major overheating issues. I was wondering how they were going to pull off 8K and 4K120FPS in such a small body with no active or even passive cooling. Hopefully these are just pre-production issues and they improve the processing efficiency to the point to where this does not become a production issue.

In other news it seems like both the R5 and R6 will have terrible battery life and the R6 at least will not be able to record video to both card slots....so I'm back on the fence with waiting to see where Panasonic goes with the GH6. The R6 also still has that 30min video recording limit.

The overheating issues are way overblown.  It is a topic being hyped on social media platforms like YouTube.  It's click bait.

Overheating issues are, as far as I know, only linked to video use, so may we take it your interest is in video? I would ask if you ARE a serious video-specific user, why not get an actual video camera?

You have to understand that the 30-minute recording limit is not a technical deficiency. It is a deliberate limitation to keep the camera from being taxed as a video camera by those countries that impose a higher tariff on video cameras than on still cameras. Does the R5 not have that limitation? If not, that could account for some of its rather surprising price.

[Tronhard]

What Robert says is absolutely correct.  In the EU cameras that can record more than 30sec of video are hit with much higher taxes or tarrifs, so the vast majority of makers of dual function cameras hold the maximum record value to 29'59" or less.

I would check what reputable tests indicate rather than heresay from sources that are not authenticated about both heating and battery life.  There is so much unfounded innuendo put out on the web these days.

The pressure to have non-dedicated video cameras perform as video cameras is an on-going issue. The concept that a MILC or DSLR can be a true video camera is rather like saying that a WWI or II U-boat (sans snorkel) is a true submarine. It was, in fact, a submersible: i.e. a vessel that can spend some time under water but must eventually come to the surface to get air. In the same way, a small, weather-resistance stills camera has challenges in becoming an unlimited video camera, that's why that market still exists.

Spot on observation about the weather sealing!

The Sony A7s Series is what everyone points to and asks why can't other manufacturers [do that].  It is because those cameras are actually cinema cameras with a DSLR form factor.  They use a 12MP image sensor, and are NOT weather sealed.

With all this video over heating hype . It would be nice at least for me not to have video at all. I just don't use it. And maybe the cost on the R5 and R6 would come down.

I agree and believe there is a market for a really good stills camera. It was for that reason that I went out and bought the Nikon Df, a fantastic unit that doesn't try to engage with video, but hearkens back to the classic film days, yet has a fantastic FF sensor.

Initially, it got rubbished by people who really didn't get the point, but it has gained much more respect as people have realized the point.

So, Canon - how about that? Make a STILL photographers' camera that strips out all the other video stuff and gives us the best solution for what we want to do???

I agree Trevor.  Swiss army knives can be useful at times but purpose built tools are better at accomplishing specific tasks.  Between a 1DX, 1DX II,  1DX III, and 5DS R I have various video options but I hate shooting video with the form factor of a DSLR and for me the XF 400 camcorder is a great video solution that doesn't take up much room in a bag.  It also has forced air cooling so that it can shoot 4K high frame rate video for long periods of time in hot weather without concern.

To paraphrase from Michael Crichton's Jurassic park, scientists and engineers sometimes spend far too much time asking whether we can do something and far too little time asking whether we should do something.
