If you do that part is owner changable because Canon sells a few different styles of them. There is a small tab in the middle of the frame that screen fits in which if pulled about 1/16 inch releases the focus screen. Invert the camera &amp; let the screen drop into place then pull the clip lightly with a fingernail &amp; very gently push the screen back into place, then release the tab.</P><P>Or do a YouTube search on how to change the screen in the 1 series bodies.</P> Thu, 28 Feb 2013 19:30:06 GMT cicopo 2013-02-28T19:30:06Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/my-focus-lens-fell-out/m-p/15855#M1881 <P>One of the focus lenes fell out. I googled it and this is not an isolated incident with the Canon 1D II. Should I send it in or is there a way to fix it myself?</P> Thu, 28 Feb 2013 19:08:58 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/my-focus-lens-fell-out/m-p/15855#M1881 tieggers22 2013-02-28T19:08:58Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/my-focus-lens-fell-out/m-p/15863#M1882 <P>If this relates to a Canon 1D mark ll you should have posted in the EOS section but either way I need to know if you mean the focus screen.
