Excerpt: So much better then the kit lens. Very well made and sharp. Lens comes with a lens shade and a padded case. I will be buying the the other 2 in this series foe sure. Fits real tight on my m10. Do a google search to see the unique way to fix this problem, it really works!
Summary: I paired this Sigma 19mm and the 30mm with the Panasonic 45-150 for a well-rounded set of focal lengths with similar quality (metal/brass mounts, polished metal finishes on top, and modest apertures).
Summary: This is a cheap and great lens, working just as well or better than my other lenses, which cost me $450 and $600. Its relatively wide aperture makes it great for low-light shooting, and the field of view is wide enough to capture everything I want to.
