Question:: How do I check for the "snappieness" of the blades in my lens?
I had my 50mm gum up, and that was obvious because they wouldn't open up all
the way, but I mean aside from the seriousness of situations like that, is
there any quick and dirty way I can check myself? Or just click click click
on it and see if it's opens and closes quickly and all the way?
