Thanks @jfolkmann! You'd be surprised how well they handle. Of course, I'm shooting with a markiii and only prime lenses – so not a lot of moving parts. And I'm pretty careful about how and when I switch lenses. Zoom lenses suffer much more as the super fine alkaline dust gets in there and can never really be cleaned out.
I spent couple of months this year shooting dogs for animal shelter, and now my 135/2L needs to visit repair center ... looks like dirt affects AF motor :(
