ok, so i tripped down some stairs, banged my knee and twisted my little finger, but what hurts the most is that i was carrying my camera with the 18-105 lens attached and my best efforts couldn't protect it as it hit the tiled floor It won't focus properly, wont zoom all the way, the shutter wont always work and looking through it you can see that the iris has detached. I'm thinking that it might just be cheaper to replace. anyone know roughly how much to fix ? going to take it in to the Nikon service place in Adelaide this afternoon. jj
