Sigma EX DC OS HSM 17-50mm f/2.8 Lens Canon EF-S - Please see description

I've taken as many photos as I can to show exactly what you're getting so please see photos for full condition. This has some lense fungus in the centre as shown in the photos. It rarely seems to be noticeable in any photos but occasionally it'll look like there's a bit of light flare in one spot which sometimes works quite well for some shots. I tried to take some test shots to show this but I wasn't able to get one where I could see it. Otherwise I've had no issues with this. Please note that this is only suitable for APS-C cameras and won't work on a full frame although I think it'll work on newer mirrorless cameras but please check before buying.
