Hello, I've been re-reading this and a few other threads for a month or so trying to decide whether it's time to purchase a new system. Hoping the knowledgeable posters here will weigh in.
I'm shooting a D7200 in a Subal housing. Primarily a wide-angle shooter. 80% of my shots are with the Tokina 10-17 and Zen 100 dome. I love the small dome and the lens' flexibility. Macro, I shoot mostly the 105 but sometimes the 60.
I've looked at the usual suspects, Sony A6700 and Canon R7, Sony A7RV and Nikon Z8. I'm drawn to the A7RV most. What I think I like most about it are the relatively compact size of the camera, the relatively small size and light weight of the Sony 90mm and 28-60 kit lens, and maybe most of all, the incredible viewfinder. My eyes aren't what they used to be, and the huge, bright viewfinder is a big plus. What I dislike about the camera, aside from the ridiculous cost, are the switch to full frame with larger heavier lenses and huge file sizes and the lack of a native fisheye.
Still, the A7RV, suffers fewer of the drawbacks of the other cameras I looked at. On the A6700, I was discouraged by the viewfinder and the synch speed. The R7, I like almost everything except the viewfinder. The Z8 had a great viewfinder and felt familiar but seems big and heavy for travel. I know in theory I could use my 105 and 60(?) with an adapter, but the 105 with an adapter added seems ridiculously cumbersome.
If I had a D500, I wouldn't be thinking of upgrading, but the D7200 low light performance and the autofocus are more limiting. I've thought about searching for a used D500 set up, but it's hard to justify spending $5000 on a setup that's in some ways obsolete.
So, should I plunge in or wait? Will Nikon actually release a mirrorless equivalent of the D500? Will Canon release an updated R7 that's a perfect compromise?
