I have this 20-35mm f/3.5-4.5ish USM that I got for work calls. It's pretty good for work calls, though I wish it was stopped up more, but for actual photography it is an ok I guess lens. Released in 1990 and can now be found for about $100, I won't complain, but a dxomark score about 12 would be cool. It also doesn't get any better stopped down, so basically all of these are shot "wide open".

Here's the biggest thing, though: The autofocuses, sucks tremendously.

I can sit there and press "autofocus" and then wait and then do it again repeatedly and it'll just... decide it doesn't want to do it?

Most of these are shot with manual focus because of that, and I'm not very good at that, so the focus is eh on most of my shots.

Also, I don't like shooting at 35mm, it feels to big, and that's the closest this lens goes! Several of these photos are cropped because of that.

tldr, I probably won't take this lens with me very many places.

Here are the decent ones:
