Meike 85mm f 1 8 stm vs sony fe 85mm f 1 8?
On paper these two are twins. Both are 85mm f/1.8 primes for full frame, both autofocus, and neither has stabilisation. The difference is who makes them and where they mount.
The Sony FE 85mm f/1.8 is the portrait lens I'd tell you to buy first if you shoot Sony full frame. It only mounts on Sony E.
The Meike 85mm f/1.8 STM is the choice if you're not on Sony, or if you want one lens that could move between Sony E, Nikon Z and Fujifilm X. It's also the original version of a line that has since gained newer models, so check which one you're looking at.
Either way you get the classic portrait view described in portraits. If you use an APS-C body, the focal length converter explains how the blur changes.
