Excerpt: I have been using the 25mm f/1.8 along with the 45mm f/1.8, 12-40mm II R, 40-150mm f/4-5.6, and 9-18mm F/4-5.6 and this is probably my favorite of the group. It's focal length is great for shooting all kinds of situations. The lens body feels solid, the focus ring is smooth, and the images produced with this lens on an E-M10 are the best of the group mentioned above. It is also the only lens of the group that is made in Japan. The others were made in China and Vietnam.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh, Strong Construction
Excerpt: I am a big fan of the Olympus MFT primes. This is my fourth one and I'm as pleased with it as I am with any so far. It is as sharp as I could hope for and renders colors beautifully. At this price, I got mine during a promotion, it can not be beat by any other MFT lens. The focal length lends itself well to distant landscapes an portraits. Olympus put a sturdy plastic case around this one, I'd rather metal. but they made up for it somewhat by supplying a lens hood.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh, Rugged, Strong Construction
Summary: Really a good lens overall, pleasing bokeh and sharpness. The only thing that bugs me at times is some vignetting that doesn't improve much when stopped down. I've used it a ton over the past several months and can highly recommend it.
Summary: This lens goes perfectly with my Olympus OM-D M-1 for portrait or impromptu photographs. The 1.8 aperture allows indoor pictures to be taken with lower light levels. The focus is very sharp. I highly recommend this lens.
