I want a good all-around lense, which is the best?thanks

Pink iridium is a great all round lens. The hard-to-find VR50 Emerald Iridium is mind-blowingly good as the one lens to do it all. I like the G30 as well, but it can cut a little too much light if it is really dumping.

I think that the lens i wear the most for anything would have to be pink iridium, it doesn't filter as much light so you can see naturally, almost clear in overcast/snow, and in sun the iridium effect comes into play and causes the mirror effect to work, and work great in the sun. They look sweet and are probably my favorite lens.
