Wow, you guys are a rough crowd!
Seriously, the title of the post was a bit tongue-in-cheek. The idea behind the post (for those that haven't read it) is simply that relying on lens caps to protect your lenses is a bad idea. I know all about the arguments about putting "cheap" glass in front of a good element, but see for yourself if you can really see the difference in your photos. I can't. But I CAN see the difference once a front element has gotten scratched!
So I'm sticking with my UV filters, which I can afford to replace as needed....
