Alright, alright, alright. I am wrong.
Thinking in terms of equivalence, f/2.8 x 2 for the m 4/3 crop factor makes f/2.8 equivalent to f/5.6. On full frame (yes, I know now, never treat m4/3 like full frame) when I’m more concerned with DOF than sharpness I try to stay below or near f/5.6 higher resolution sensors, which I’ve been shooting quite a bit with recently, are impacted by diffraction. It is a habit I need to get out of when shooting landscapes, thats for sure, and after talking to Rishi about it, f-stops equivalent to 5.6, 6.3, or even 7.1 aren’t going to be impacted by diffraction on a 16MP chip. You’re correct, Demon Cleaner, the landscape images would have benefitted from f/5.6 or f/8.
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.
