Even wide opened the lens consistently produced sharp, contrasty images with very pleasing colours, OOF blurring and bokeh. My only (minor) concern is the lens shade, it fells off easily if not properly attached, I almost lost it on several occasions. Just be careful with it.
Optically and mechanically the lens is great, the overall rendering is pretty much on par with modern Fujinon lenses. Nothing to complain about.
I really like the lens and can recommend it to anyone who doesn't afraid of manual focus.
All the best,
