I am somewhat wary of "revolutions" in photography, especially these days with every man and his dog* on the internet touting every new release as the Next Big Thing. There are IMO very few true photographic revolutions; most of them are just multiple logical
evolutions occurring together for the first time in a single camera body. Digital itself
is of course a true revolution; everything else that has happened to sensors since can arguably be classified as differences in degree rather than in kind. And all that gear packed around it to tell the shutter what speed to fire at and what aperture to open or close the lens to and how to focus it... none of
that is radically different from anything you will find in the final generation of film bodies.
Naturally someone who graduated from an *istDL directly to a K-3ii without using or allowing themselves to be aware of anything that happened in between would beg to differ, as would some hypothetical photojournalist who got to play with the prototype MZ-D on its first intro then got put in hibernation or lost on a desert island until the K-1 appeared... but the enthusiast user or professional photojournalist who managed in the intervening years to own and shoot every Pentax DSLR ever made would likely see some truth in it.
* Sometimes literally "...and his dog...". If you don't believe me, just check out Peter Gregg's YouTube channel, or any of the numerous photographs of Ken Rockwell's fluffy terrors that he puts up from time to time.
