Sigma 19 mm f/2.8 EX DN
11. Summary
- compact and quite solid build,
- very good image quality in the frame centre,
- decent image quality on the edge of the Micro 4/3 sensor,
- well-corrected chromatic aberration,
- slight distortion,
- moderate vignetting on the Micro 4/3 sensor,
- silent, quick and accurate autofocus,
- good price/quality ratio,
- three-year guarantee with a possibility to extend to by additional two years.
Cons:
- significant vignetting on the APS-C sensor,
- noticeable coma,
- spherical aberration not corrected properly,
- work against bright light could have been better.
The Sigma 19 mm f/2.8 EX DN is neither an outstanding nor an excellent lens. It is optically a bit worse than its 30 mm brother. Its performance on the edge of the frame doesn’t bowl you over; it would be more justifiable if we dealt with a “pancake” lens, not a full-scale and quite slow “prime. If you add to it noticeable vignetting and coma the situation seems to be quite bleak…

On the other hand you get a wide-angle EX series lens at a quite affordable price which can provide sharp images across the aperture range and for most of the frame. What’s more, this lens is optically better and cheaper than such instruments as the Olympus 2.8/17 or the Sony 2.8/16 - from such a perspective it would be difficult to complain. Especially that the Sigma can find its own market niche e.g. among the owners of Sony mirrorless cameras who, so far, can’t complain about the excess of lenses. It’s enough to say I had a lot of problems with getting a specimen of this lens for the tests because the first batch sold like those proverbial hot cakes.
