Sony a7s overheating

This isn't surprising given Sony's canny knack of avoiding sony a7s overheating 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 sony a7s overheating in the camera acts as a conductor two ways, both from the CPU to the body and from the body to the CPU, sony a7s overheating, 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.

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. 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

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.

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. A simple option is to open up the rear screen as well as any of the memory card and port doors on the side of the camera.

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. Shooting at 4K 60p does reveal some limitations of the model with overheating being a not uncommon problem. If you are looking for some solutions to overheating, then Stefan Malloch has six options to try out. The simplest option is to adjust the auto power off temp setting to high. This will simply allow the camera to get a little hotter before it shuts down. Some of the biggest culprits for power and processing usage are networking options like Wi-Fi and Bluetooth since those connections will run in the background.

I don't think a cage would make much difference, at least not the ones I'm using, I would think you need enough shade to actually block a substantial amount of the solar radiation, a few pieces of metal around a camera body probably isn't enough. Your "thermos" would have heat from internal source mounting up and not getting anywhere melting the chip , while the "glass bottle" would just dissipate the heat outside, unless the external temperature was higher than the internal. As a Sony user, I can say that it has been pretty easy to overheat the last 3 Sony A7 cameras I have bought - particularly the A7r3 - when shooting 4k 30p video for any length of time. Posted August 6, It's always a good idea to shade cameras from direct sunlight not only because of overheating of the camera itself, but because I've also seen lenses become damaged from heat. The editor of Digital Camera World, James has 21 years experience as a journalist and started working in the photographic industry in as an assistant to Damian McGillicuddy, who succeeded David Bailey as Principal Photographer for Olympus. As you noted, and I pointed out to Dan, internal heat generation radiation is outbound as well as thermal absorption inbound. The more temperature difference, the more efficient cooling. And what's a "net sink" this guy is talking about? Posted August 6, But no way heat from solar heating would travel "backwards" to a hotter area like the article states.

Remember too that all those peltier type coolers that are insulated boxes can be reversed to warm food as well as cool it.

Unlike their competitors, Sony has had three generations to work out the problems they have run into with their cameras. That is why Sony is one of the most trusted brands to turn to when it comes to getting a great quality camera for a fair value.

Now if there was a heating source IN both bottles, AND in the sun, the glass would have the heat from the sun AND the heat from within while again, the thermos would only have the internal heat. Funny how the camera buying internet has gone from "what are the most sick cinematic camera movements? Join now for unlimited access. And of course a glass bottle will allow heat out with an internal heat source but put it this way. In the same circumstances, your "thermos" might negate some heating by the sun, but the internal heating would be bonkers and no cameras are insulated like vacuum bottles anyway. And what's a "net sink" this guy is talking about? And that Sony is also trying to do a Canon and deny anything that might suggest recall, or alterations or coloring the body in a lighter shade. Even if the heat might dissipate very slowly, if the temperatures inside and outside are almost similar, it will dissipate to equilibrium. Heat traveling backwards, no.
