Yongnuo officially announced a new version of their budget-friendly 50mm lens: Yongnuo YN 50mm f/1.8 II. The new model is already listed on eBay for around $74 (only Cann EF mount available).
Optically, the lens looks the same as you still get 6 lens elements in 5 groups which produce a 46° angle of view, and a 7-blade aperture that runs from F1.8 to F22. The new Yongnuo YN 50mm f/1.8 II lens has an improved mechanical structure and uses a new coating technology, which has increased focus accuracy and helps control ghosting and glare. A chrome-plated metal mount has been introduced and the lens can be switched between manual and autofocus modes.
