This lens is an amazing condition and it barely shows any signs of wear at all. It came attached to another lens and I actually think that they may have lived together permanently for most of their lives. Luckily it also came with the original case in the original objective side cover so those are part of the package. The leather case itself is a little on the squished side but it still protects it and holds it pretty good. And now for all the marketing talk let's hear from my fabulous assistant, AI:
