I just wanted to see if this problem I had is something other people have ever experienced:
the metal piece between the front element and rubber focusing ring came loose.
Autofocus still works however the shutter locks up frequently and the camera says "Reattach lens"
I was abit surprised as I've never had a lens ever do this on me and now I'm being told repairs will cost over a thousand USD...
The problem with the lens , start since day one with a lots of photographers.
I think the Mr. Michael Reichmann, is the only one got it fixed free.
So just pay to get it fixed and continue on with your life. you going to spend only money
and remember don't work hard, someone else can do it for you,
and you get pay for that if you are in USA
Good luck
