The guys I know ( and oddly I had a coffee with one today- acceredited sports photographer for a number of local and national papers), like the reality that a real-time optical viewfinder gives, with the ability to determine depth of field to a degree that you just cannot get with a digital v/f or a screen. He said that, not me, and he works with seriously long Canon ( sorry Pentax) pro lenses that have wafer-thin depth of field. Things may improve as technology catches up, but at the moment nothing touches a true optical DSLR. I for one ( sadly not a pro) would not ditch my optical v/f-ever!

I have to ephasize - Pentax produces really amazing and cool gear but it is rather a niche for true enthusiasts. OK, I know some professionals using Pentax but believe me, it is huge minority. And some of them think of switching to mirrorless

So far I have not met a single pro who would use a mirrorless DSLR against an optical v/f camera . That's amongst my UK contacts. It may not be -at the moment- a Pentax, but when their Canon and Nikon pro camera start to become unreliable they will look for another camera. If Nikon & Canon do not have a suitable camera, they may -and I emphasise may-turn to Pentax. So Pentax do not offer a pro-level camera at the moment ( although I could argue for the K-1), there may well be a market in due course. These are all hypotheticals, of course.
