I have almost decided to make the 50 1.2L my gift to myself. Someone talk me out of this $1400 purchase. Sample reasons that will cause me to put away my credit card: - Someone can speculate that Canon will come out with a better 50 1.4 which will focus faster & more accurately than the one I purchased & returned last year and that reported reliability issues will improve. - Someone can tell me to wait for a Conurus to start conversion of Contax N 50 1.4, that I shouldn't worry about possible mirror clearance with 5D, that it image quality will be exceptional, and that focus speed and accuracy will be in the ballpark of a Canon 50 1.2L. - There is some other substitute for the breathtaking, "did I really shoot that?" quality of a few of shots from the last time I rented this lens. (I commonly used 1.8, so 2.8 zooms not an option. 85 definitely not a substitute, and 35 probably not the best choice in my experience) - That there will be a rental company that will open nearby that will always have this in stock at last minute. - That the infrequent focus issues I had first time I rented this lens (and decided not to purchase) should stick in my mind. (Focus issues were not as bad as 50 1.4, just more annoying than I thought should happen in a lens so expensive.) - Many other reasons, I'm sure. Thanks.
