Siden Canon lancerede EOS R6 og EOS R5 i forrige uge, er ordrebøgerne vist blevet fyldt flere gange, men nogen har undret sig over, hvor længe det faktisk er muligt at filme i 8K-opløsning med et kamera, som ikke har en vifte, der afkøler kameraet.
Det er en kendsgerning at optagelse i 4K, 6K og ikke mindst 8K genererer meget varme, og Canon har udsendt en pressemeddelelse, som forklarer, hvor lange sekvenser man kan optage i 8K på et EOS R5 og i 4K på EOS R6.
Fra pressemeddelelsen:
| Model | Resolution and frame rate | Mode | Approx. shooting time(23°C / 73°F)*1 | Recommended scene |
| EOS R5 | 8K 30p | Full Sensor Width | 20min | 8K productions where a full frame mirrorless can be utilised to get unique angles alongside a main camera or additional cropping for 4K productions |
| Full Sensor Width RAW | 20min | As above but with the additional workflow flexibility of RAW | ||
| 4K 120p | Full Sensor Width | 15min*2 | Shorter bursts of slow motion | |
| 4K 60p | Full Sensor Width | 35min*3 | High frame rate high resolution productions and independent films | |
| APS-C Crop(5.1K Oversampled) | 25min | When additional reach is required with higher frame rates – e.g. wildlife and sports and news gathering within a 4K production or even for tighter Full HD crops in post | ||
| 4K 30p | Full Sensor Width | Not limited by heat | Interviews, longer duration capture such as weddings | |
| Full Sensor Width High Quality(8.2K oversampling） | 30min | When additional resolution is required with a 4K30p production or for a Full HD workflow where cropping can be desirable with high resolution | ||
| APS-C Crop(5.1K oversampled) | Not limited by heat | When additional reach is required – e.g. wildlife and sports and news gathering within a 4K production or even for tighter Full HD crops in post | ||
| EOS R6 | 4K 60p | 94% sensor width(5.1K oversampling) | 30min | Independent films shooting action or with the option of slow motion at high resolution |
| APS-C Crop | 35min*3 | Independent films shooting action at high resolution with the need for additional reach for sports or wildlife or tighter crops | ||
| 4K 30p | 94% sensor width(5.1K oversampling） | 40min*3 | General purpose |
Canon har også oplyst, hvor længe man må vente på, at kameraet afkøles, før man kan filme igen:
| Model | Resolution and frame rate | Waiting period
(23°C / 73°F) |
Approx. max recording time after waiting period |
| EOS R5 | 8K 30p | 10min | 3min |
| 20min | 8min | ||
| 4K 60p | 10min | 10min | |
| EOS R6 | 4K 60p | 10min | 5min |
