Selling a Sigma 70-300mm APO Macro Super lens as defective. Sold as is
The auto focus system does not seem to be locking on the focus hence wont allow clicking. The manual focus seems to be working fine, but have not checked the pictures.

Bought this to work with film camera and had not used it in many many years. Initially I assumed that it was a problem of compatibility with newer DSLR. But then checked it on the original film camera that I got this for, and the result was the same. It is possible that it is just jammed, and needs to be serviced. But I cant be sure.

Comes with the front and back lens caps, lens hood and a padded lens case.
