Viltrox AF 85/1.8 II XF 85mm
This 85mm f/1.8 lens from Viltrox is widely praised for its sharpness, beautiful bokeh, and solid build quality, especially given its affordable price. Many users find it comparable to much more expensive Nikon or Sony lenses for portrait work. However, some reviewers report issues with chromatic aberration, occasional slow autofocus, and a notable problem with the lens hood being stuck in the reverse position. A few also note slight softness at the edges and an abrupt bokeh transition, but overall it is considered excellent value for the money.
