Sigma 19mm & 30mm f/2.8 EX DN Lenses Hands-On

13 February 2012
  • Excerpt: A couple of upcoming lenses that I’m looking forward to trying out are the Sigma 19mm and 30mm f/2.8 models for NEX and Micro Four Thirds cameras.  I’m particularly looking forward to getting a production model of the 30mm f/2.8 lens in the NEX mount since it works out to a 45mm-equivalent (60mm-equivalent for Micro Four Thirds models).

[REVIEW—SIGMA 19mm f2.8 EX DN lens]

11 April 2013
  • Excerpt: This lens is available in either a micro four thirds mount for Olympus and Panasonic cameras or an E mount for the Sony NEX range. On MTF cameras the film equivalent focal length is 38mm and on the Sonys, with the larger sensor, it is 28.5. There is no internal image stabilisation so it is best suited to Olympus cameras with their in-body IS. Construction quality is good and the auto-focus linear motor is very fast, accurate and quiet.

19 mm f/2.8 EX DN

15 May 2012
  • Excerpt: In January 2012 the Sigma company presented two new lenses designed for mirrorless cameras - the Sigma 19 mm f/2.8 EX DN and the Sigma 30 mm f/2.8 EX DN. To tell you the truth that launch took me by surprise. In the case of the Micro 4/3 system a small sensor allows to construct physically small and fast lenses so quite significant dimensions of the Sigma with the aperture of f/2.8 don’t fit here at all.
  • Cons: significant vignetting on the APS-C sensor,, noticeable coma,, spherical aberration not corrected properly,, work against bright light could have been better.

Sigma 19 mm EX DN

14 June 2012
  • Summary: The Sigma 19 mm EX DN is a lens that is comfortable in the hand, solidly finished and that focuses quickly and quietly. This lens has remarkably little trouble with ghosting, even if you do not use the supplied lens hood. For a micro-43 lens, the Sigma 19 mm EX DN is not very compact, but this is precisely an advantage for those who wish to focus manually.
  • Pros: High resolution in the center, Solidly built and beautifully finished, Free pouch and lens hood, low priced
  • Cons: No built-in image stabilization, Reasonable performance in terms of distortion and chromatic aberration, Resolution in the corners is less than in the center

Expert Review

9 May 2012
  • Summary: Z drugiej jednak strony za niewygórowaną cenę dostajemy szerokokątny obiektyw z serii EX, który daje nam ostry obraz w prawie całym zakresie przysłon i w znacznej większości kadru. Co więcej, obiektyw który stanowi lepszą optycznie i jednocześnie tańszą alternatywę dla takich instrumentów jak Olympus 2.8/17 oraz Sony 2.8/16. Patrząc na to z tej perspektywy trudno narzekać.
  • Pros: zwarta i dość solidna obudowa,, bardzo dobra jakość obrazu w centrum kadru,, przyzwoita jakość obrazu na brzegu matrycy Mikro 4/3,, dobrze korygowana aberracja chromatyczna,, niewielka dystorsja,, winietowanie umiarkowane na matrycy Mikro 4/3,, cichy, szybki i celny autofokus,, dobry stosunek jakości do ceny,, gwarancja wynosząca trzy lata z możliwością przedłużenia o dodatkowe dwa.
  • Cons: spore winietowanie na matrycy APS-C,, zauważalna koma,, niezbyt dobrze korygowana aberracja sferyczna,, praca pod ostre światło mogłaby być lepsza.
