This unique macro lens provides magnification from 1:1 to 5:1. That's 5 times lifesize, which is a heck of a lot of magnification. The tradeoff is that this lens is macro ONLY- you can't focus any further away than 4 inches. Do not buy this lens if you want to focus further than 4 inches! In excellent condition, with clean glass. Remember: close-up only! Also, it's manual focus.
