Can anyone who might have experience with both pieces of glass give me a compare and contrast of the 50mm 1.8 (super cheap at $99 with very good reviews) vs. the 50mm 1.2 L lens (expensive with excellent reviews). I know there's a significant difference btwn the build quality, the weight and the bokeh. I'm seeking info specifically related to image quality, contrast, yummy L glassness. I have the 1.8 and am considering the move to the 1.2 L. Would like input from users of both as to if the upgrade is significant enough to warrant a change and the expense. Thanks so much.
