• Youtube: Tony Northup's comparisons D850 vs D810 vs Canon 5DS-R vs Sony A7R vs Olympus E-M1 II HiRes
  • has lots of severe banding when shooting at high ISO with electronic 1st shutter and LED lighting!
  • noise seems similar to D810 but it does seem to have slightly better dynamic range and of course more pixels which give different grain pattern but perhaps not significantly more detail as this is so dependent upon many other factors
  • much more dynamic range than the Canon 5DS-R
  • marginally better high ISO noise at ISO 25,000 and marginally better low ISO dynamic range vs Sony a7R, but image quality is very similar at ISO 100-1600
  • but strangely has MORE noise and LESS dynamic range than an Olympus OM-D E-M1 mark II in HiRes mode!
