I found some time today to do some further testing, I plan on shooting an event next weekend and wanted to freak the wife out a little more. She’s worried her 40D is coming back in a box of parts. 
Anyways, here’s the video of the second test, this time around I ran the test at 50′, otherwise the AEG and BBs are the same (350fps G36, .20g BBs.) [ View DSLR Lens Resistance Testing, Experiment #2 ]
