Sigma 18-50mm F2.8-4.5 DC OS HSM

I just received a new Sigma 18-50mm F2.8-4.5 DC OS HSM that I bought on ebay. I am using it on my K30. When I tested the lens, I cannot get the f stop down lower than 4.5. It will go way above it. I even tried it in manual. Is this lens older and not compatible with my camera? I don't know if I need to try & return it. I was looking forward to using it, but really disappointed now.

Are you zoomed out to the long end? If so that's the problem. Try bringing it back to 18mm and then setting the aperture.

Thank you Voice. I guess I just assumed if I changed it to manual, I could set it to anything and it would just say over or under exposed. So glad to have this forum for help when my brain malfunctions.
