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.
the difference is negligible at best. But the big difference is AF speed

Summary: This is the classif focal length. Olympus seems to have their stuff together with the release of their fast prime lenses. Having moved from the Panasonic 20mm f/1.7 lens to this, I have to say I was very impressed. While my impression is that the Panny is a hair sharper, the difference is negligible at best. But the big difference is AF speed, at least on an Olympus camera body. This one focuses fast, whereas AF speed is the Panny's one weakness.
Excerpt: This not only squeezes the most light out of a shot for me, it really lightens the load! I had been carrying my 12-40mm PRO around on my EM-1 as my most utilitarian lens, which it is, but now I feel like I can take the camera out as a fast, lightweight street shooter and have a little more fun. And who doesn't need at least one f1.8 prime?
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh
Summary: Excellent general purpose lens. Between the in-body image stabilization in my OM-D and the f/1.8 aperture here, I'm doing low light nearly as well as my Canon 6D and the typical f/4 zoom. But way more portably -- you don't feel like leaving your m43 system home at times you would leave the DSLR. One example, shot with this lens, attached.
