So I acknowledge that i am privileged enough to be have a big lot of Pentax gear that i've accumulated over the years, and as happy as I am with Pentax, I am now experimenting with Sony.
Part of the reason to look at Sony was for its 135mm lens options that are wider than F2 and autofocus, but also the eye AF option.
essentially I was looking at Sony as a toy/backup to my K1.
I picked up the A7RII after looking at the A7II, the A7RII and A7III. I am loving the megapixels count on the A7RII. yet one major thing that is making me get irritated with Sony (no, its not the menu, as you'd expect me and many others to say), but its the limited dynamic range on the A7RII compared to the K1. The details my K1 captuers in the shadow is incredible. Moreover, the color information captured in RAW on the K1 is HUGE! As per the Detailed comparison, which claims that A7RII has better colors, but Dynamic Range 14.6vs13.9 to Pentax

for those who have switched over completely or partly to other brands, what have you seen as a draw back from your main system and a secondary system?
