What are the alternatives to the yongnuo yn50mm f 1 8 da dsm?

The closest swap is the Yongnuo YN50mm f/1.8 DF DSM. It's also a 50mm f/1.8, but it's made for full-frame cameras, so it's the one to consider if you move to a full-frame body.

If you stay on APS-C and want a different focal length, the portraits guide says a 56mm f/1.2 to f/1.4 does the same job as an 85mm on full frame. For a wider everyday option, the lenses guide suggests a 33-35mm f/1.4 to f/1.8 as a fast standard prime. The Yongnuo YN16mm f/1.8S DA DSM is a much wider APS-C prime, better suited to landscapes and interiors than to portraits.
