Get Pentax K-1 II at B&H Photo.
The Pentax K-1 II is a full-frame 35mm camera. See also my review of Pentax medium format.
I was impressed with the image quality in pixel shift mode of the Pentax K-1 Mark II, and Pentax has now improved it. Worth a try perhaps, as 36 with a good pixels shift exposure is something more akin to 60 megapixels. I never did find Sony’s pixel shift persuasive like Pentax, but I may try it again and compare.
The Pentax K-1 Mark II will be a 2nd priority for me (behind the Hasselblad H6D-100C) and it will be another week before it arrives. I am interested in knowing if readers out there have interest—I expect it to be low, but maybe I'll be surprised.
I ponder whether this will be the last DLSR I will ever review—interest is moribund in DSLRs from what I can tell.
