Moving air and dust when zooming I read about two potential problems, which I cannot fully understand – both related to moving air and dust when zooming. Fuji vs. Fuji says when comparing Fuji´s standard zooms: “Eye-blow: Another area the 18-55mm f/2.8-4 wins in is eye-blow. If there is any, I can’t feel it. With the other two lenses, you might dry your eye out if you zoom out too quickly. The 18-135mm f/3.5-5.6 is the worst here.“ And Philip Sutton writes in his blog „However, it is the dust and filth that creates the amazing light that one can only find in Myanmar. The thought of sucking all of this into my camera each time I zoomed, was not comforting. … I started reading a lot about the 18-135 mm lens. I loved the fact that it is sealed.“ I cannot understand the eye-blow problem at all, because there is no direct connection between lens and ocular in mirrorless cameras. The dust problem I can understand, but I have a hard time to believe that this is a relevant problem. Does anybody have a thought, experience or deeper insight into this moving air and dust “problem”?
