The 50L definitely needs an update asap. Among the modern lenses, it's just a prehistoric dinosaur right now. The 50 art is leaps and bounds ahead sharpness wise. Buying this lens at that price is just a complete rip off.
I didn't know sharpness was the most important characteristic of a lens. I'm so glad you're here to educate all of us on what aspects of image quality we should find most important. I guess we've foolishly thought that things like bokeh and color rendering matter. Thanks for setting us straight!
Not that sharpness is unimportant, but some people treat it as the sole criterion for evaluating lens performance, probably because reducing a complex set of objective and subjective parameters to a simple, uncomplicated number makes it easier for simple, uncomplicated minds to grasp.
