singularone 1 Posted August 10, 2022 I prefer the 45 degree viewfinder and used it for over a decade. I can comfortably look down to compose and don't have to hyper extend the neck whether shooting macro or wide. 1 Share this post Link to post Share on other sites
phxazcraig 123 Posted August 24, 2022 I now have both and can try them out back-to-back starting next week. I've shot the 180 since 2016 on a D810 then D850 Nauticam housing. I was able to try a 45 degree finder at the Digital Shootout in Bonaire in June. In July I bought a Z9 and housing for it, and I was told you had to change from a DSLR viewfinder to a ML viewfinder, so the 180 I had would not ... work? I bought the 45 degree ML, and I'm sure I'll like it for macro. But for wide angle, I'm not so sure. There are a lot of times I take a landscape shot and immediately rotate the camera vertically and get a portrait shot of the same subject. With the 180, this is trivial. Anyway, I was curious to see if the 180 would fit the Z9 housing, so I tried it. Fits just fine! So I looked closely at the housings just now - the viewfinder mounts are identical! Maybe the ML viewfinders somehow make the eye-detect monitor/viewfinder swap work, but I don't think so. At any rate, I have both viewfinders and will find out soon if there are any deficiencies in the DSLR 180 on the ML camera. Share this post Link to post Share on other sites
