Review on Samyang SY12M-MFT-SIL 12mm F2.0 Ultra Wide Angle Lens for Olympus/Panasonic Micro 4/3 Cameras, Silver: A Perfect Lens for Stunning Landscape and Architectural Photography by David Fisher

I received a bad copy. It wasn't able to focus decently at every distance or setting. While my sample was good, I'm not sure how to get sharp focus on my OM-D E-M5. When focus looked normal, all frames were blurry. I tried it in astrophotography as every lens needs to be able to focus at infinity. nope Blobs instead of dots. Color rendition was good though, so I think someone who gets a working copy of this lens will be pretty happy with it. I'm not that lucky. Two stars for color rendering, cosmetics, and a decent hood and pocket.
