Hello, all, I thought I would share this matter with our knowledgeable film enthusiasts. I recently (today) inquired with an eBay seller in regard to whether the lens caps on his/her Vivitar lens were Vivitars or generic (the auction does not specify). The seller responded exactly thus: "Generics. Does that make a difference?" I replied that it does--that "Generic caps can be had anywhere, and they are often of lesser quality. A lens is always worth more if it has the correct caps...and always worth less if it has generics." The seller has since replied with two insulting and rather outrageous messages. Here is the first: "Just wht we need. Another expert. Don't worry about my sales. I intend to block you from ever buying from me. You are too stupid to qualify." I responded that I may report him/her for his derogatory remarks, and he/she replied: "Have fun. Anyone stupid enough to think generic caps on a generic lens changes the value is too stupid to be on EBay. I get tired of answering dumb questions like this. Now, go tattle to EBay, you jerk!" I find this quite incredible. I guess he/she is so smart that he/she thinks a Vivitar is a "generic lens." I suppose all of those Series 1s out there really just amount to a heap of junk. I suppose, too, that a collector would never care to have an original cap on his/her vintage lens. Am I wrong in any of this? All I asked were if the caps were real Vivitars. When he/she was shown to be perhaps trying to avoid the fact that they are generics (and that I helped, with my question, to point this out to prospective buyers), he/she becomes irate. eBay is becoming a real zoo.
