Excerpt: I will never understand why everybody wants 1.8 prime lenses for micro four thirds. 2.8 is more than enough, period. I Use it with Olympus M-10Very well built lens,it has a hood MR OLYMPUS MAN" do you hear this???? how can a company that make such great cameras be so mean!!!! for God sake just for your company's image put the hood and disguise it with the price!!! all your lenses come without hood SHAME ON YOU.
Pros: Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh, Rugged, Strong Construction
Excerpt: Despite it's clunking sound when the camera is not on this lens produces very crisp images and extremely nice colors. In combination with a Sony a600 this is a must have lens for beginners as for pro photographers.
Pros: Consistent Output, Fast / accurate auto-focus, Lightweight
Summary: This is my first step into prime lenses and I'm impressed. Very sharp image quality. Great bokeh. Not as wide as I thought, but that's just from my inexperience with prime lenses. Great image quality and bang for your buck for sure! The rattling that you hear goes away once you turn on your camera, I wouldn't even worry about that for a second. I really like the ridged focus ring too.
Excerpt: The only thing that really surprised me about this lens is how small the front element lens; otherwise it's a basic accessory for most any lens toolkit; a fast prime. Bokeh is good and focus speed is fast, and ar 30mm it's the equivalent of 60mm on a full frame camera. All I really wish it could do more of is be faster, a f/1.8 or 1.4 version would be killer.
Summary: You can get some very sharp photos with this lens, even wide open. Its small size and light weight make it an excellent prime lens for my Sony Nex cameras, and its 2.8 maximum aperture, though not super-fast, is plenty fast enough for most situations. A faster aperture would mean a bigger, bulkier lens, and I'm happy with this tradeoff.
