There is NO doubt in my mind that some day I will have one of those in my bag. I've worked with one and it is IMHO the finest prime below 85mm that Canon makes.......enjoy you lucky dog........
This lens is so much more expensive than the f/2 version. I'm still waiting for someone to convince me to spring for the L. Your pictures are beautiful and I'm lucky (?) I don't have a woman in my life who would kill me if I were to get the L version.
Would you say it has been worth every dollar you spent on it?
