Just as lensbaby month was starting, mine hit the floor. That little round ring is the collar that holds in the optics. It is held in with three small plastic nubs, and two of them broke off. The collar is stuck on the optic and the composer is ruined. So, off to amazon to replace things. I wait and wait and wait. The package got lost! Youngest helps me get the collar off of the optic, so, off to ebay. There I found a composer pro, and was outbid. So, found another, with an optic, much much less than new, and after almost a month of waiting I have a lensbaby again. Now I have to try and get in the last bit of lensbaby month!
