Just for the record, I ended up with the 1.4, and I really don't regret it. What a wonderful lens this is. And I really love shooting this wide open. For me the extra stop was the most important reason. But I also like the fact that it's optically corrected and don't rely on heavy digitally correction. I don't doubt for one second that the f2 is a amazing lens as well. But for me the so called magic of the 1.4 won me over
