as i shoot documentary video when i am not sitting around on my chesterfield writing stuff, i am excited about the potentiality of using my pentax glass on a camera that shoots raw video... beyond excited, in point of fact. who uses autofocus? not me. video people like manual focus. it's kinda a thing.
several months ago i was hopeful that someone at Pentax would release a video-capable mirrorless camera that met my hybrid requirements on the k-mount--or at very least meet me in the middle with something that keeps up with the Jones'... unfortunately instead i got myself an ambivalent stomachache... why won't they do it? if nikon can, why can't pentax?
none of this means i hate Pentax, nor does it mean that i will be using different glass for my work. all it means is that evidently i was the last one holding out--that even leica will be offering better video options in 2019. with Pentax, a clean HDMI out video option is out. the K-1 mark ii is not a viable option for me with it's uncertain bitrate...
if you don't think raw video is a big deal, maybe you should check out this video?
ProRes RAW Part 3: How to Edit and Grade ProRes RAW Footage - YouTube My previous reply was based on the information in your post, which made no mention of video (certainly not raw video) or manual focus lenses. Now I have more context
It's certainly possible Pentax will come out with a mirrorless system at some point, but based on the collective experience of most in these forums, I think we'd probably agree it's not right around the corner and certainly not within the 6 months before your imminent switch to Nikon. It's not that Ricoh
can't do it, but simply a case of funding, available resources and product strategy priorities.
My original suggestion is still relevant - to wit, there's justification for using multiple systems... in your case, one for stills, and one for (raw) video. Or, if the non-Pentax system meets your needs for everything and supports all the glass you want to use, there's nothing wrong with switching. The main reason I bought my A7 MkII was to support all of the manual M42, M39, L39, K and F mount vintage lenses that I collect and shoot. I could use a subset of those - M42 and K-mount specifically - on my Pentax DSLRs (and occasionally do), but a mirrorless camera with short registration distance and EVF focusing accuracy is a better option for me in this specific application. I don't own a single Sony FE mount lens
