R5 vs A7sIII

it is an interesting story. I think Canon and Sony were playing cat and mouse with these announcements. Canon blinked first and now Sony is most probably going to build their campaign around NO OVERHEATING. 
Based on the below specs Sony looks more attractive unless you are into photography. 12 MP is not really a photo oriented camera in 2020.

looks like a7sIII will complete with R5 for video and a7rIV with 61 mp will compete with potential R5s in high MP segment.


Rumored A7sIII specs recap

  • New 12MP sensor with fast readout
  • records FHD 240fps, 4k120fps 10bit 4:2:2 and 4K120fps raw over HDMI
  • 600mbps bitrate
  • Base ISO 160 for S-LOG3
  • Max ISO 409600 (video)
  • 16bit RAW output
  • Sony claims 15 stops dynamic range
  • world’s highest resolution new 9.44 million dot EVF (QXGA resolution)
  • new kind of passive (noise free) cooling system
  • no overheating, no recording time limits
  • UHSII card support
  • Looks pretty similar to aSony A7rIV.
  • fully articulating screen like the one used by the Sony ZV-1.
  • announcement late July
  • shipment start mid August
