I did a search on the forums and found a lot of 24-70 'L' vs 'L' prime posts but couldn't find anything about the non-'l' primes.
I just bought a used 5d and got an excellent price on it. I just sold my 40d and I'm currently in the process of selling my crop body lenses. I should have around $1250 for lenses after everything is sold. I mainly do outdoor family and kid portraits and could really see myself getting the 85 1.8 and 35 f/2. I could shoot almost everything with this combination and later (when I have the money) get something for the wider end.
BUT, I have been helping a friend out with weddings (and getting paid for it) and I'm afraid of missing shots I would have otherwise gotten with the 24-70 'L'. Although the extra stops on the primes would come in handy. I'm just beginning to be half-way descent and building enough confidence to charge for my work.
I've been beating my head against the wall trying to decide what I want to do, and I just can't make the decision.
