Like Dylan, I just ordered my first big white (300 2.8 LL) and the $6700 was a quantum threshold for me to cross. I don't know, perhaps after this getting past a 10K barrier will be easier, but somehow, I don't think so. I am wondering how other people do it? Are that many professionals (i.e., people making a decent living from photography using these lenses) to justify the price, and drive Canon profits, or are the lenses selling to people like me who are avid/rabid enthusiasts? Just a question.
Don't worry, you will cross the $10,000 barrier eventually
I went all out first with 600II so that the 300II was "cheap" a year later!!
These lenses sell to two markets:
1) Large photo agencies that supply them to their pros.
2) Affluent amateurs...doctors, lawyers, dentists, executives, business owners, etc...
I think the actual amount of professional photographers buying these would be very low. Sports pros get them supplied for the most part and wildlife photographers that can actually make a living are a rare breed.
