Hi Mr. Butler,
Regarding ISO, from what I can tell the ISO is overstated by 1 stop at high ISO. For example, at an exposure of 1/500s f/8.0, the X100s is at ISO3200, while the NEX7 is at ISO1600. The images appear to be the same brightness, so wouldn’t this be a 1 stop ISO inflation?
Not that I don’t think the X100s is still better in some ways at ISO1600 vs ISO3200 on the NEX7, but it seems to be a significant difference in ISO reporting

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
