Some interesting takeaways.. - At ISO100 A7RII shows similar levels of detail and dynamic range to the D810. This is more or less in line with Jim Kasson's takeaway when looking at engineering dynamic range. At base ISO it's competitive with the D810. - From an adapted perspective, most lenses work great up to about 300mm. - Above 300mm for big primes 500mm and 600mm didn't work properly but Tony speculated that it was likely just a firmware update needed. -Focus speed is good but not quite as fast as native. - Steadyshot makes the A7rii the best hand held low light shooter. - For video, the super 35 4k mode looks to be about a stop behind the A7s in low light. A personal opinion... I saw another poster on another forum speculate that the 11+7 raw format may be hurting the theoretical dynamic range and noise for shadow areas. I'm going to post to Jim Kasson and see whether a full fat raw file could yield better shadow noise and dynamic ranges results. *EDIT* to remove erroneous quote from the video. Thanks Rob.
