having broken bayonet (unfortunately plastic) My original 18/105, and the repair costs are exorbitant, I wanted to make the leap to a more powerful lens to capture the faces, real emotions. And of course with bayonet metal. Well, now, there has weight at the end of the case, but I found the same qualities as my previous goal. Is has noted, the delivery date scheduled Amazon was reduced by 2 days. I received it just before leaving on WE. ca it was a nice surprise!
