>>303223Basically this
Just try out as many of the features of the dslr as you can, within reason. I've never bought a body of craigslist but Ihave bought a couple lenses. What I do: Look at the lens, make sure no fungus, oil on blades, dents, scratches, ect. Then put the lens on the body you brought, set your camera to Av, snap off a couple test-pics and try each F-stop in full-stop increments, make sure they all work. Then tryout (provided it's a AF lens) different AF points and make sure it's working with no grinding noises/ect. Then set your camera to MF and try that out. Once again make sure no grinding/ect. Then pop the memory card into the cardreader you brought which is hooked up to the laptop you also brought. Look for any problems with the lens. If this all works, ask the guy if he'll take $50 less than the offered price. The worst he can say is no. Let the guy know in advance you plan on firing off test shots and bringing a laptop to make sure everything's working. Chances are if he seems reluctant to let you do this, the lens is busted.
