How resistant are L lenses against the shocks/vibrations?

[AcutancePhotography]

I've been told that sports photographers sometimes find that the vibration from constant air travel will loosen screws on their lens mounts. I've had this problem frequently with the screws holding on the hot shoe of my Canon cameras.

You sayin' that Canon shooters often have a screw loose?

I knew it!

I don't mean if lens drops down on the floor. I mean how resistant are they against the shocks let say while driving on a really bad road. Assume that lenses are stored in a padded camera bag. Are those vibrations critical for any kind of glass displacement inside of lens?

I have wondered about the same thing. But wouldn't you think that the camera and lens would sustain far more shock and vibration while you carry it around your neck than it would inside of a padded bag? At least when I carry it for hikes it moves around bumping my chest and my hip.

One night when I was out of town, my pit bull decided she was into my 16-35 f/2.8 II...which means that she pulled it off a shelf that is four feet off the ground, and used it as a chew toy. I was sure that this was the end of the lens but, honestly, it works perfectly, cosmetic damage aside.

From my own experience the Canon L lenses are quite resistant against vibrations and shocks. Earlier this year I was hiking in northern Thailand's mountains. During a short stop I put down the backpack to take a closer look on one of the wild orchids. Unintentionally I hit the backpack, which started bumbing down the mountain. It were about 50 meters. Half way down the tripod flew out of the backpack and during some bumps the backpack flew up to one meter or more. It finally stopped in the valley of a dry brook. It took me about a half hour just to climb down the steep mountain to retrieve the tripod and backpack.
Nothing was broken and all of the equipment still works fine. Included in the backpack were: a 5DII, TS-E 24 mm II, TS-E 45mm, Tamron SP 24-70 f2.8, TS-E 90mm f2.8 & EF 70-300mm F4.0-5.6 L, a carbon fibre tripod, a dozen filters, my tablet PC etc. Only the ball head and panorama plate got some scratches and a screw was lost. Of course the backpack collected a lot of dust and dirty during its journey. The backpack is a 5-year-old Lowepro Primus AW.

Each model of lens is different. Cruise on over to lensrentals.com and look at the reports for individual models. They just tested the new 16-35 f/4, and say it will likely be much more reliable over time than the old 16-35 f/2.8, which can apparently survive a pit-bull attack. I guess maybe the new f/4 will be able to handle a Great Dane?

Anyway, the point is that each L lens model is different, and some are more delicate than others.
