I had the 5d3..i have an a7sii
the DR capabilities are worlds different.. a7sii is awesome in that sense.
I have the same experience. I have a 5DII and a Nikon D800 and the difference between the two IQ wise is more than noticeable. It's huge, yet when I look at the data, it shows the DR as identical. So, hence my question, what are they measuring?
