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).
Excerpt: I'm using this lens on a BlackMagic Pocket Cinema Camera. It's giving me the shallow depth of field that I was looking for in a wide angle lens, but is limited in it's uses. I got what I paid for.
