I've decided to get the EF 135mm f/2 L, and I'd like to get a good one on the used market. I've checked out a couple of the rental places (Lens Rentals, Borrow Lenses), and they don't have any in stock at the moment. I'm not in a great place geographically to be able to look at one locally on Craig's List.
Other than those venues, where are some other places to procure this lens? I've always had good luck with third party vendors on Amazon, although I've never purchased a used lens that way. I know that Amazon has a warranty program, even for third party vendors, but luckily I've never had to use it, so I don't know how good it is. Whatever thoughts you have on purchasing a used quality lens online would be greatly appreciated. My timeline is such that I can wait for a little while, but I'd like to make a purchase within the next 30-45 days. Thanks in advance for your advice.
