Upload & Sell: Off
It's a great lens, but with it's own character.
I recently compared it to the Zeiss Planar 50/1.4 ZF, which was a lens I considered purchasing.
Here is my comparison review sample images, with mouse over comparisons and such.
Well, the Zeiss has benefits, but I have changed my mind with regard to purchasing the ZF and selling the 50/1.2.
