Questionttartisan 85 1.8 AF for like $90?? whats the catch

saw that ttartisan has an AF 85 1.8 for under 100 bucks apparently. i have the a7c and the 35 1.8 and i shoot night street mostly. would an 85 even be useful for that or is it more a portrait thing. whats the catch at that price :)

The catch is it's $90. Rendering's probably fine, AF probably isn't Sony's. 85 is a weird focal length for night street anyway. Get a 50.

ok fair. 50 it is then probably :) the 35 is basically glued on anyway
