Excerpt: Great, small, high quality lens. Focus is super fast and quiet. Images are of high quality. I prefer prime lenses and this one is a super performer in a very small form factor. my copy takes a bit of force to mount it in the bayonet - not sure if all versions of this lens have the same issue, but it take much more force than with my Oly 17mm f1.8. It's hard to be critical of this lens, but weather sealing on these Oly primes would be a nice feature.
Pros: Consistent Output, Fast / accurate auto-focus, High Quality Image, Lightweight, Versatile focal length
Excerpt: Loving the weight and size of this lens. Bokeh great, shots crisp. Not found anything that don't like so far...... Bought the Vello LH-40B Dedicated Lens Hood (Silver) to go with it - but this is not worth the money - very difficult to fit - in fact have not got it to work yet!
Excerpt: It's worth 4.5 stars. All I can say is sharp. The resolving power on an E-M5 is shocking, even at pixel peeping. 5 for sharpness.<br /><br />Focus is fast, should say very fast. Very good in low light, not near darkness.<br /><br />This lens is good for more than portraits, I like the focal length on an M43 body. Better at isolating some subjects.<br /><br />My gripe with most Olympus Lenses is minimum focus distance.
Excerpt: This is a nice lens. It's sharp and fast focusing. The only thing that bothers me about it is the plain plastic build. But the price was good and the pictures are great so it's still a keeper.
Excerpt: This is a pretty great lens for the price point. Sure the product itself is made of plastic, and feel slightly cheap in the hand. But when it's on the camera (my GH3) the reduced weight is a good selling point. I kinda forget it's there. I don't think it's quite as sharp as I had anticipated wide open, but still does quite well. Autofocus is quick and very very quiet. Doesn't focus quite as fast as my 25mm panasonic/leica but is plenty fast to capture those moments.
Summary: Absolutely love this lens... At 90mm (35mm eq) it's the perfect portrait lens and it's light. I usually keep it in my pocket so I don't have to carry a bag. If you shoot micro 4/3rds I definitely recommend this lens.
