ISO mattered at Spot-meter- while capturing a Star at Night
My first Nikon body was F801 ( July 1998 ) and I had to live with its dead (preserved ) body all this while so I was casual and cautious of investing in the next Nikon , D 7500 ( bought this September 2021 ) . Being ,otherwise supposedly near perfectionist , but in photographic pursuits somewhat more fussy about capturing over the details . D7500 was revealing what ISO 51200 means with Nikon AF and AF-S lenses alike .on instinctive hand held shots as well .
