What We Like
+Excellent value at approximately $300 MSRP with exceptional build quality for the price
+Outstanding bokeh rendering with smooth, creamy out-of-focus areas and clean specular highlights
+Solid center sharpness, especially when stopped down to f/2.8 with minimal purple fringing
+Reliable autofocus with face and eye detection suitable for portraits and video work
+Professional controls including AF/MF switch, custom function button, and USB-C firmware updates
+Compact and handleable design, considerably smaller than f/1.4 alternatives
Worth Knowing
−Softer corners on high-resolution full-frame sensors, even when stopped down
−Aperture ring turns too easily and can slip out of auto setting without resistance
−Autofocus/manual focus switch feels cheap compared to rest of lens and less reliable
−Autofocus not super fast and occasionally requires patience, unsuitable for sports photography

Read our notes on general
The Brightin Star AF 85mm f/1.8 is a solid entry into autofocus portrait lenses, offering good build quality and image quality suitable for most applications. With excellent value at roughly $300, it compares favorably against costlier options, though corners stay softer on high-resolution full frame bodies even when stopped down. For portraits and calm scenes, the autofocus speed is absolutely sufficient.
