Camera store sales people make no money from people buying old lenses off ebay, markets etc. Let me assure you there is a world of fantastic glass out there at very reasonable prices if you're prepared to focus manually. Here's a review I just uploaded if you have the time to view https://youtu.be/5Z674h_sMcA + there are a few others and more coming in my channel. If you want AF and great glass then the Fuji range is exceptional, but you will pay more.
