Canon points assertion relating to EOS R5 & R6 Overheating Throughout Video Recording


In response to the rising concern relating to the overheating of the EOS R5 and R6, Canon has simply formally launched a press release. Under you possibly can learn it:

The EOS R5, one of many newest additions to Canon’s full-frame mirrorless digicam line, gives class-leading autofocus with high-resolution and excessive body price video recording choices utilizing the utmost width of the full-frame sensor at excessive bit charges.  Inevitably, this mix of options has the potential to generate some important warmth, which is able to restrict recording time. 

Canon has taken a number of steps to handle the potential for overheating, together with:

  • Magnesium alloy was used within the physique to dissipate warmth away from inside elements
  • An “overheat management” operate to cut back warmth era when the digicam is in standby

In regard to the set up of a fan: The choice to not set up a fan throughout the physique was made as a way to preserve the EOS R5’s compact measurement, light-weight development and climate resistance.

Earlier than recording begins, the EOS R5 and EOS R6 show an estimate of the recordable time based mostly on the present digicam temperature and the set recording mode.

Canon has revealed and included under the approximate recording and estimated restoration instances for 23°C / 73°F environments and ensures that the digicam will warn customers when it’s getting too scorching. Moreover, tricks to scale back overheating in addition to recovering time are listed under.

How will you scale back warmth buildup within the EOS R5?

That is what Canon recommends:

Set Overheat Management operate to “ON” (default). When the overheat management operate is enabled, the film measurement and body price are robotically modified whereas the digicam is in standby mode to suppress the rise of the interior temperature.

Between recordings, it is suggested to show off the digicam and place the digicam out of direct daylight. You may also use an exterior fan to dissipate warmth.

These are usually not all the time going to be choices which can be attainable. If you’re a working skilled there might be jobs the place utilizing this digicam specifically modes might get you into actual hassle. You may’t inform a consumer, sorry now we have to attend for 20min earlier than we will shoot once more, and oh, by the best way, then we will solely document for an additional 3 minutes. Once more, select the best instrument for the best job. In case you use an R5 in a state of affairs the place that is going to occur then you don’t have any one accountable however your self.

How lengthy will it take for the digicam to get better?

Estimated digicam restoration instances are indicated under. The time till full document time is obtainable will range with ambient temperature, continued digicam operation, and the chosen capturing decision.

Whereas there may be fairly substantial hindering of recording instances when capturing 8K or 4K 60p (oversampled), these are unlikely to be modes that almost all of customers are going to shoot in for prolonged durations of time.

What it’s essential to clearly word, is these downtimes listed by Canon are for working in situations the place the ambient temperature is 23 C / 73 F. If you’re working in a lot hotter situations then the ready instances and subsequent recording instances are going to be elevated and decreased respectively.

In case you do need to document a number of 8K or 4K60p (oversampled) then one choice could be to have a number of digicam our bodies, however that isn’t going to be a financially viable choice for lots of customers.

What concerning the EOS R6?

Here’s what Canon says about haet and the R6:

Just like the EOS R5, the EOS R6 gives highly effective film recording and stills capabilities inside a compact physique design. On the highest body charges and resolutions, warmth is inevitably generated. We imagine the EOS R6 gives one of the best in school efficiency, particularly for fanatic photographers and video content material creators.

The EOS R6 can document as much as the 29 minutes 59 second recording restrict within the 5.1K oversampled 4K 60p mode at (23°C / 73°F) earlier than encountering any warmth associated points throughout the digicam and as much as 40 minutes of 4K at 30p.

If it’s essential to document for longer durations of time and don’t need to encounter any main warmth points, the R6 might be a greater choice than the R5.

It’s a step in the best route that Canon has addressed this difficulty that has been grabbing the headlines. Whereas it doesn’t remedy any overheating points it does present potential customers of the digicam with the knowledge wanted in order that they’ll use the digicam correctly.

Look, these cameras aren’t going to be for everybody. When you’ve got particular necessities or work in situations or environments the place these limitations might have an effect on what you might be doing, then don’t purchase the digicam.

A mirrorless hybrid digicam is all the time going to have compromises as it’s constructed with two totally different functions in thoughts. I nonetheless imagine that each the R5 and R6 might be good cameras if used inside their limitations. Wouldn’t it be nice in the event that they didn’t have any warmth or recording limitations? Completely, however they do.

I don’t need to defend or chastise Canon, as a result of there are two sides to each story. Canon most likely oversold the digicam to a sure extent, and in hindsight, they most likely ought to have talked about all of those points lots earlier on or of their preliminary press briefings.

It’s best to think about the R5 as a 4K digicam that may shoot 8K and never an 8K digicam that may shoot 4K. proportion of individuals shopping for the R5 most likely received’t be recording in 8K for a wide range of causes, and overheating is just a type of causes.

What do you concentrate on theses statements from canon concerning the overheating points? Please tell us your ideas within the feedback part under.
