This lens has a few issues. First, the body within the lens has a slight wobble. I don't know what if act this effect will have on pictures.  The aperture opens quickly but takes about 5 seconds close fully. The focus ring still appears to work and the lens is free of scratches, dust or haze. I am listing this lens low as is in the hope that somebody may still be able to make use of it. It was found in a camera bag with Nikon SLR and other Nikon lenses, so I am nearly certain that it is compatible for this lens type, but please look closely at the pictures to verify this lens will work for you. Thanks for looking.
