"I've had this lens for a while now and it is indeed everything you've heard about it: - Sharp: excellent a the wide end, very good at telephoto. Good enough so that I'm not constantly fumbling for my prime when I want *sharp* photos - Rugged: Beautiful metal finish shouts ""Quality"" and...

This lens is so versatile I feel like it's a must have lens for any micro 4/3 shooter even if you're not a pro (I'm certainly not). The focal range is fantastic, that extra 5mm on the long end versus a traditional 12-35 makes it a viable portrait lens in a pinch.
