Sigma 18-125... Value
It depends. If you like the lens, then you should fix it. If not, then get another one.
I do have one and use it as a walk around lens when I travel. I also have a Tamron 17-50 f/2.8 and several fixed lenses between 28mm and 50mm; so the Sigma is on the low end of the IQ scale. But I use it because of the focal length range. YMMV.
My lens is having an issue at about 22mm it won't focus correctly and clicks into place after that. I'm sending in for repair but how much should I actually spend on it?-- hide signature --
