Actually I replied to you there. Imo you’re wrong and the core hw (processor, image engine, memory, sensor) are exactly the same. We’ll soon see who of us is right.
As for the other features, I know they are added, they are not hw n a strict sense. It’s like saying that a computer with the same cpu, memory and drive, has a different and bigger case and a webcam, compared to another one.
P.s. I’m quite sure the af is the same as nx300, just tuned via sw and NOT via hw. Again, we’ll se who’s right or wrong, w/o the need of being rude or offensive 🙂

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.
