I added Canon EF 24-70mm f/2.8L USM image samples. These were taken at a party with a 580EX II attached.
This was where I encountered an “Err 20” when I shot stills after taking 3 to 6 minute videos. Hopefully this can be solved with a simple firmware update.
Other image samples include Canon EF 85mm f/1.2L II USM and Canon EF 800mm f/5.6L IS USM.
All of the images shared are not how Canon marketed the camera to be used as.
Your welcome Neil.
Shadow, I need more time with the 5Ds R to make a definitive verdict on the AF system. I am used to the AF system of the 5D Mark II, 7D and 1D Mark IV. I have the 7D Mark II but its AF needs to be serviced by CPS. as keepers were disappointing.
Jay, I rarely encounter tight patterns in my shoots. I seldom photograph those hence my being fearless on getting the R. If I see any I will try to do some image samples as well.
