Sedan Canon lanserade EOS R6 och EOS R5 i förra veckan, har tydligen beställningarna rasat in. Men några har undrat hur länge det faktiskt är möjligt att filma i 8K-upplösning, med en kamera som inte har en fläkt för att kyla ner den.
Det är ett faktum att filmning i 4K, 6K och inte minst 8K, genererar mycket värme över tid. Så Canon har skickat ut ett pressmeddelande som förklarar hur långa sekvenser man kan ta i 8K på en EOS R5 och i 4K på EOS R6.
Ur pressmeddelandet:
| 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 också upplyst om hur länge man behöver vänta på att kameran ska kallna, innan man kan filma 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 |
