Thursday, I was shooting a time lapse sequence for work.  It was a the second day into the 4 day shoot when I heard the words "I s#$%!.  I just knocked over the camera".  I walked over to see what happened and there was my 5D and the 17-40 lens laying on the ground.  The lens hood popped off and outer lens ring was laying next to the lens.  The red O-ring was around the focus ring as was the threaded spacer ring.  The camera had the obvious dings and scratches.  When I checked it all out, the camera was staying on even in the off position.  

Once I reassembled everything, I set the camera back on the tripod and began shooting again. It still shoots fine but I have to remove the battery to get it to turn off. I shot through today and then took it into Mike's Camera in Boulder.  The good news is, I will know what the issue is in 3 days, the bad news is, it is a 3 week repair time frame.  OUCH.  I will now pull out the old Rebel XTi to carry me through the repair process.

While at Mike's Camera, I did get the Cokin graduated neutral density filter system.  I have never used an ND filter.  We'll see how it goes.  I hope to learn a few things from Randy Van Winkle

The only other ND filter I am thinking I might want is a full ND filter.  Stay tuned for more photos coming.
