Fortunately there is an E to Z adapter, so I can use the Laowa F mount onto the MSC onto the E to Z mount. I have no interest in zooms or AF lenses, and 24 is not hardly wide enough for what I want.
I went to a shop today and gave the A7's and Z6 a whirl. The A7rII was honestly not sluggish at all for how I shoot, but the ergonomics was shockingly bad. I assumed it was going to be poor, being Sony, but wow. They really outdid themselves. Looks like I will be going Z6. Lovely Nikon ergonomics as usual. You can tell which camera was made by electrical engineers and which was made by photographers.
