Sirui aurora 85mm f 1 4 vs meike 85mm f 1 4 ii?
On the specs, these two are close to twins. Both are 85mm f/1.4 primes with autofocus, neither is stabilised, and both are made for full frame. Both frame the same way: 85mm on full frame, and about 128mm equivalent on APS-C.
The real difference is mount. The Sirui also comes in Fujifilm X, and the Meike doesn't. If you shoot Fuji, the Sirui is your lens. If you shoot Sony E, Nikon Z or L-Mount, either will fit, so pick whichever one suits you.
For portraits, 85mm is the classic choice, and the lenses for portraits explains why. At f/1.4 the focus is very thin, so read aperture and background blur before you shoot wide open.
