… and one more thing. We found a very interesting behavior where sometimes sharpness would oscillate with aperture. In other words, f/1.8 sharp, f/2 a bit sharper, then f/2.8 is less sharp, then f/4 is sharper, then f/5.6 is less sharp, etc.
And this would change from copy to copy, and would vary based on if you’re looking at the center vs. the corners.
I think with these complex lens designs, with such demanding resolution sensors (the pixel pitch on the RX100 is quite small), one starts to see odd behavior that challenges things we would’ve taken for granted in the past (‘stop down for optimal sharpness, until you hit diffraction’).
So, again, there’s enough variability in performance that what you see here may or may not be the best, or the worst. But is something you can expect from a random sampling.
I’ll try and put the RX100 III copy variation results into a widget and share on a forum post, if I get a chance. For anyone curious, since I already have the shots.
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.
