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.
Yes, it’s stupid annoying when they don’t read the description or know how to Google, but I feel it’s okay to ask questions to confirm that’s you’re getting what you expect. “Is this compatible with this camera” isn’t always a simple question to answer unless you’re quite familiar with the ecosystem, and even if a person can figure out the answer, it doesn’t hurt to confirm with the seller who may well know the equipment better than you.
Even a question like 'what mount does this use?" - you might have written EF in the description, but if they don’t know that EF is a type of mount then reading the description isn’t enough, and for stuff like lenses the model name is more of a description and it’s easy to get them mixed up.
