Can I adapt the leica macro elmar m 90mm f 4 to sony e?
The Macro-Elmar-M 90mm f/4 is a Leica M mount lens, and this page only lists it for Leica M bodies, so I can't confirm a Sony E fit from the site.
Adapting is the usual route for Leica M glass on mirrorless bodies. The Lenses page explains that mirrorless mounts are shallow, so old manual-focus lenses adapt easily and cheaply. This lens is fully manual focus with no stabilisation, so you'd be focusing by hand, which suits macro work anyway.
I don't cover Sony E bodies on this page, so I can't tell you how it would frame or perform on a specific Sony camera. Check the lens's full page for its details before you buy an adapter.
