Sony a7s overheating

This isn't surprising given Sony's canny knack of avoiding in-depth reviewers like myself, by giving the demo units to Paris Hilton types instead.

The new Sony A7S III rolled out amid a great deal of fanfare thanks to its raft of impressive specs, but its biggest statement was that it can record 4K 60p for over an hour without overheating — double that of the Canon EOS R5. On paper, it looked like a Sony had absolutely routed Canon. The R5 can only shoot 4K 60p for 35 minutes or 25, if oversampled before shutting down, while Sony claimed that the A7S III can manage in excess of 60 minutes. Standard recording at 4K 30p causes no heating issues on either camera. Indoors, both numbers hold true.

This isn't surprising given Sony's canny knack of avoiding in-depth reviewers like myself, by giving the demo units to Paris Hilton types instead. The thermal energy from the sun on a hot day is absorbed by the black chassis meaning the heat sink in the camera acts as a conductor two ways, both from the CPU to the body and from the body to the CPU, the latter really hammers recording times and reliability outdoors. Canon said it themselves in the recent Komodo style cine cam patent Now that very fast processors are in the latest cameras, heat is becoming more difficult to manage. A comment on Hugh's YouTube video explains why the testing needs to be more thorough. Most of the reviews were put out in a hurry and don't tell the whole story on the A7S III thermal limitations. The trunk of any car in Phoenix, Houston, or Florida where I live will easily exceed F for 6 months of the year. It looks like you are trying to make some honest assessments here but there are a multitude of variables here that you and others are still missing. As you noted, and I pointed out to Dan, internal heat generation radiation is outbound as well as thermal absorption inbound. No reviewer is understanding this point since they are not Engineers. I get that but then they extrapolate conclusions which are simply wrong — some favoring Sony and Canon and some against both brands. It is simply assumed to be worst on the back side since this is what Photographers look at all the time.

As more and more advanced video recording features are packed into compact cameras the problem of overheating will become more and more common. Sony is one brand that has had some issues with heat already. Even the latest models — outside some of the video-specific cameras with integrated fans — have struggles when in their top recording modes and less-than-ideal external environments. By changing this from Standard to High you can prevent the camera from shutting down until it gets hotter and that might just do it for you. Most newer Sony cameras offer this option. Try it out and see if that fixes your main overheating issues.

When he shot with both cameras outdoors, though, in the direct Florida sunshine, the A7S III actually overheated first — shutting off at 23 minutes while the R5 made it to The Sony was consistently measuring about five degrees hotter than my Canon, and it actually shut off at about 23 minutes where my Canon went to about 32, 33 in 4K After the comments section went apoplectic at his methodology, Watson repeated the experiment with a greater emphasis on test conditions — this time both cameras fared a little better, but again the Sony tapped out at 29 minutes while the Canon soldiered on to Fellow YouTuber Hugh Brownstone achieved near identical results in direct sunlight, even without the same intense heat as the Florida sun.

Again, no understanding in the article at all. But no way heat from solar heating would travel "backwards" to a hotter area like the article states. Stormtrooper a7siii? Take it into the hot sun still cold and what is going to happen do you think? Your "glass bottle" will always dissipate the same internal source heat chip much better than your "thermos", unless it gets way more heating from the sun than what the internals produce, or your "thermos" has a really massive internal heat sink. Canon said it themselves in the recent Komodo style cine cam patent Recommended Posts. Remember too that all those peltier type coolers that are insulated boxes can be reversed to warm food as well as cool it. A comment on Hugh's YouTube video explains why the testing needs to be more thorough. Corporate shoots for Subaru of America.

This release was a fairly substantial jump in terms of image quality and videos specs, bringing it all the way up to 4K 60p with bit internal recording. Moving to bit has been a good move for Sony and it is nice to see it coming to most all of their new releases.

The DR on the Sony is great for such a small mirrorless camera. Video Hummus Posted August 7, The more temperature difference, the more efficient cooling. Isn't that what they both said they did in those tests? Followers 0. Since cameras don't literally melt from sunlight exposure, that is quite unlikely.
