Great performing lens that has some oxidation on the outside (rubber grip).  I used this on a Canon 5D with an adapter (not included) and it works great.  It is one of the better 300mm manual lenses that you can use on a digital.  This will work on all Nikon digitals and the professional and pro-consumer digitals will work with the aperture ring otherwise you have to guess for your exposure (look at a picture on your screen and adjust).  I think I have a generic front cap but do not have a nikon rear cap (waiting on the shipment from china).

It is worth every bit of $70... but I am cutting you a deal.  I've been keeping this around close hold because I love the manual lenses and have been hesitant after stupidly getting rid of the Super Cosina!!!  This is just as super!  There are others of these on Ebay so you may want to check each of those first. You'll probably get a better deal. Ok, I think I have said enough.
