Great article - hopefully one I'll never need to put into practice!

Slightly off topic, but would you or anyone else know how to change the distance scale window on my 16-35L MKII. Somehow it got cracked. The lens works fine but I find the crack a tad irritating especially as I don't know how it happened....
Yep, I did the same thing with my 70-200/2.8 LIS II. Order up the window and adhesive ring, pull the old one off and pop the new one on. It's a 5 minute job and cost me about £28 ukp
