I’ve noticed recently that selling my lenses have been quite difficult. I keep getting young kids asking all sorts of questions that could be answered if they googled the model number. “Is it autofocus?” “Is this for full frame?” “Will this work on my camera?” “Is it good for real estate?”
It’s like a whole younger generation of photographers don’t know how to research things and get their information from youtube and tiktok where you can’t search model names or technical specs.
Can’t say this ever happened to me with camera stuff, but I had multiple sellers jerk me around when I was selling my track bike wheels, I had the axle length plastered about three times over the ad (track/fixed gear bikes often have a thinner hub size than regular road bikes) and I still had buyers show up for whom they would be the wrong size.
