I bought this lens on e-bay. Colors are rendered beautifully. At f/1.4 it’s great for isolation but focus is so critical, like the doll picture I must have moved slightly, hence, instead of the right eye, the kimono was in sharp focus. Nevertheless the OOF elements are beautiful, smooth and colorful.
Wide open images are rendered sharp but it a touch of softness, stopping down to f/2.8 onwards images become sharper with increased contrast.
Thanks for looking.
