I picked it up Sunday, and got to try it out tonight at the VW 21st Century Beetle Launch Party featuring a performance by the Black Eyed Peas. (All photographs are ©2011 Megan Green, do not download or otherwise copy without my permission.)
I used it on my E-3 body;
800 ISO
Vivid Color
Noise Reduction On
Sharpened once in Photoshop
Highly caffeinated
Two gin and tonics
Barely ate all day
Hand held.
The last photograph is at a focal length of 200mm. I'm *really* happy with this lens. I picked it up used from Adorama.
