I'm crying deep inside that I may have to break the news to my wife that I think I killed my Sigma 18-125, my prime everyday lens. I think the dust may have done me in. It works fine indoors but if you take it outside in bright light it won't catch focus, it just keeps hunting. I put a 55-250 lens on the same camera body and it worked fine. I'm going to pull it out now that I'm home and clean it real good and check the contacts, I hope it work out. Right now I am not in the position to buy another lens :(

It works fine indoors, but not outside in bright light?

Do this:
Set the lens on the table, shine a table lamp through it or any other source of light, take a picture from other end. So you may illuminate any dust inside it.

Let's hope that really works.

Of course a sealed lens would be pretty much better for those conditions but if a new lens isn't a possibility right now... :| Do you have a possible replacement lens like the standard 18-55mm for the moment?

:( I'm screwed. I cleaned the polarizer, took it off then cleaned the amazing amount of dust that got thru the polarizer and sure enough, without any effort I could see the dust inside then front element. I'm getting a little more focus catches but maybe a little more than 50%. I knew I should never have taken my personnel lens but the 55-250 is too narrow for the type of shooting I do. I guess I'll call Sigma on Monday and see what kind of $$ damage I'm looking at.

The guy that holds the Government Purchase Card has sympathy for me but we don't know the rules if he can do that, keeping my fingers crossed
