I started a thread a few days ago on which lens I should buy next. I got a lot of responses. Thanks.
A couple of you recommended a 50-1.8. I looked on eBay. A new one averages about $100. There are, however, 6-7 vendors selling used ones for as low as $40. Each vendor selling the used ones emphasize the condition. "Smoooooth Glass!!!" "EXTRA CLEAR GLASS!!!"
I understand the reason for having a clean lens, but why do these sellers emphasize the condition with capital letters and exclamation points? Is there a problem with buying used lenses?
