I had the f/1.4 but the motor gave out so rather than pay to have it fixed I just bought a f/1.8. For 130$ canadian it is ridiculously sharp. I would say do yourself a favour and buy one of these and take the apx 1500 you save and...well...do whatever with it. Sure the 1.8 is like a cheap toy but so what? For the price of the 1.2 you could buy 10 of these!
