Hey there, I'm wondering if anyone who likes to do street photography can comment on lens choices? I've been interested in doing more street photography in general, and have an opportunity to pickup a pre-owned 135L for a good deal, so I'm wondering if anyone uses that lens on the street? I've used my 85L on the street before but it's a bit heavy and slow to focus... I gather the 135L won't be a light-weight either, but I understand it focuses very quickly. I also use my 50L a bit on the street, but you have to get pretty close which can eliminate the candid aspect.
