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 Jeremy Carpenter

Several pictures included. The first was on f5,6, the second on f4 and the third I don't remember. I really like this lens. I bought it thinking I'd see all the hype and just return it if it doesn't live up to expectations, but I have to say I really love this product. It's a fairly heavy lens and feels like it's of decent quality. The optics are not bad, except for glare. I think they may have missed some of the premium coatings that would be on glass on more expensive lenses. It doesn't matter to me as I like to mix exposure and hold my finger to block out the sun in the foreground and then underexpose for my sky shot so lots of flare isn't a problem anyway (see first photo). This lens works well for street photography, although it's a bit chunky compared to other MFT lenses. With a manual focus lens and such a wide field of view, you can just focus to infinity, set the aperture, and shoot from the hip. Auto focus is not really necessary. I like the lens, I will not return.
