8K Shootout: Sony a1 vs Canon R5

There aren’t many 8k cameras on the market at this time, but two of the most interesting are probably the Sony a1 vs Canon R5.

  • Sony a1 and Canon R5 record 8k internally
  • Canon EOS R5 has a few options for 8k recording that allows you to pick an aspect ratio or ALL-I, IPB, or IPB lite compressed
    • 8K-D adds 8k RAW, 8k RAW lite, and 24p
    • ALL-I is h.265 10-bit 4:2:2
    • IPB is h.264 10-bit 4:2:2
    • IPB lite is h.264 10-bit 4:2:0
  • Sony a1 has fewer options for shooting 8k being limited to 24/30p at a 400-200 MB 10-bit 4:2:0
  • The Canon EOS R5 overheats quickly so comparing how much footage a camera can capture over 2 hours
  • Canon R5 shot for 22 min, 6 min, 4.5 min, 11 min, 5 min, and 5.5 min before the 2 hours were over or 49 minutes of 8k recording over 2hours without andy battery changes with overheating 6 times
  • Sony a1 recorded for 52min before running out of space then he formated the card and recorded for 30 minutes before the camera needed a battery and then recorded for 22 more minutes before running out of space and needing a format, which was finally followed by 52 minutes of recording for a total of 117 minutes of recording time over 2 hours with no over heating
  • From here there are lots of samples showing off rolling shutter, low light, autofocus performance, and more
  • If you’re taking 8k video with only quality in mind the Canon R5 is the way to go, but you can’t trust it to shoot for more than 20 minutes at a time
  • If you need to record 8k video uninterrupted the Sony a1 is the only option, but it would be nice if it recorded 8k 10-bit 4:2:2 internalally
