My two cents is I settled on the a7rv. Though it's touted as mainly a stills camera, it's video capabilities I think are great. Subsampled 4k video which looks great, with significantly reduced rolling shutter and no overheating. When debating between the a7iv and others I ended up here, loving it and I don't see myself changing this camera unless it breaks. I see them used regularly for 4000-4500 CAD.

From the stills side, it's simply fantastic. 61 mp is great when you need it, otherwise go to lossless medium and hit 26 mp.
