I ran across a 50mm f1.4 lens recently and no longer need this one. Comes w/ rear cap only (never had a front cover). Its in pretty good shape and not anywhere as dusty as the picture depicts. There appear to be several tiny dust flecks within the lens elements, but its never affected any pictures that I've taken. Aside from this, the glass is free of scratches, etc.
