Sony a7s overheating

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, sony a7s overheating, it looked like a Sony had absolutely routed Canon.

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.

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.

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. Unfortunately, no camera goes without its flaws.

Oh please, come on, last time I checked, laws of thermodynamics still hold Add some shade and it sounds like the Sony will survive. Only 75 emoji are allowed. They're black so they don't show up in reflections or cause color casts on set. Since Sony is using the camera body as a heat sink, putting on a cage should help since less of the body would be exposed to direct sunlight. I prefer the R5 look straight out of camera. Only rain.

That Sony camera from a cold start left in the sun in a very hot environment WOULD be getting heat into it the exterior could well be hotter than the internals so that means it CAN build up to the temp it overheats at faster You should also not leave your equipment in the trunk of your car in extreme heat for this reason.

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.

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. Of course, any camera in direct sunlight would overheat faster, but that's not because heat "travels backwards" along the heatsink unless the camera is hotter from the sun than the chip. Overall though my theory is that Sony didnt really take the 'high road' but the Canon decided to take the 'low road'. Video Hummus Posted August 7, A normal part of my workflow is to leave gear in my car when I'm shooting with other gear i. Only rain. Most of it is just plain wrong. Canon make white lenses so in regard to these overheating beasts, out in direct sunlight, a white body is going to reflect more direct heat than a black body. Sign in here. I read somewhere that the A7siii have also been pretty delayed.
