picked up an old sigma wide "macro" (1:3) but. its aperture seems to be chosen randomly some of time. turns out this was a known issue on early models and sigma would repair them. this lens is from 2000 and looks basically untouched, so it's probably one of the faulty ones that never got turned in for the fix. i'll try calling sigma tomorrow and see if they'll do the fix on a 20+ year old lens lol. I doubt it but hey it might save me from returning it x . x

update: i returned it just fine 👍

anyway, subject is the same assassin bug on the same plant from last time, but no crop! wowee! BUG!
