Excerpt: The 19mm on a micro four thirds is about 38mm field of view in 35mm terms. Similar to the 35 lens I used on my Leica back in the film days. A great lens for most purposes. This lens focuses close, real close. Works fine and takes great images. The smooth focus ring is strange but since I don't use it much it is a non issue. Overall it is a nice handy unit.
One of the best lenses for the money glad I bought it

Summary: I have this for my Sony NEX to replace the kit lens and it is great. Color and contrast, C/A and vignetting control are superb compared to the kit lens. The only thing is that it is a pretty long lens. Plus although it resolves much more detail than the kit 16-50mm lens it's only 5-15% sharper. Maybe I got a soft copy because this lens should be even sharper for a prime but it's not as bad as the kit lens.
Excerpt: I wanted a prime at a good general-purpose focal length. It was between this and the panasonic 20mm f1.7, but the latter cost much more. I saw the Sigma used here at Adorama and got it. Very pleased with the service and product. The lens arrived a couple days early and is in excellent condition. Not sure the image quality is that much better than my kit zoom, at 19mm, but maybe a little.
Good little lens but beware Warehouse discounted products.

Summary: I got one of these through Amazon warehouse. The one I received was missing both front and rear caps, Even though boxed correctly. The front element was covered in dust and fingerprints! I returned that one and got a "new" lens that is working just fine thank you. This is more a warning for anyone getting something through Amazon warehouse. They clearly don't do a very good job inspecting the items they take in.
Summary: It took me a little while to get used to the chattering sound it makes when the camera is turned off but as long as I know that's normal and not a defect I can live with it. I haven't had a chance to take too many photos with it but the few I have taken look great. I took a beautiful sunset photo with it yesterday which made me decide to keep it.
Excerpt: It is very light weight and the photos it takes are very sharp. Great indoors when takin family and friends at a gathering. The finish (silver) looks fantastic and seem very durable. So far no cons.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Strong Construction
Summary: Aside from the rattling sound when this is attached to the camera and off (normal according to the various sources I have read), this lens focuses fast, is sharp and has very good color rendition. I took away 1 star because the focusing barrel is smooth. A little texture for added grip would be good.
Summary: It is a great lens for M4/3. Definitely worth the money. It is larger than I expected considering the size of the Panasonic 14mm. I don't give it 5 stars simply because I have mounted some of my old manual focus Nikon and Minolta lenses on the camera with adapter and they all out preform this lens as well as every other Micro 4/3 lens I've put on the camera. Those old lenses are pretty impressive.
