Testing 2nd hand lens: your advises
I'm about to buy Canon 100-400L 2nd hand from another person.
This is the first time I buy such expensive lens, and also the first time to buy used one.
How can I test it to ensure that it's 100% ok ?
Of course, I should look for scraches, dust and focusing, but I'd like to hear suggestions for more complicated tests.
