Bummer

Melinda Jamieson "luvmyfrg", Amazon

  • Summary: I think it would be a decent lens, but does not work with the Nikon D7000. Wish someone had said something before buying. :(

Should have been smarter

Matthew Howe, Amazon
9 July 2008
  • Summary: A 20mm f1.8 prime for $400.00? What was I thinking? At f1.8 the lens is unacceptably soft. Better at 2.8, but still not great. It's not until f4 that the Sigma matched the sharpness of my Nikon 17-55 f2.8 zoom. A full stop slower!

User Review

HQ, objektiivi
23 December 2013
  • Excerpt: Koska piirto 2.8 laajemmilla aukoilla on alle dslr-käyttäjän vaatimustason ja 2.8 valovoimalla on saatavilla samaan hintaan zoomejakin, jotka 20mm lisäksi kattavat polttovälialueen 17-50mm, en voi suositella tätä objektiivia. Sopiva hinta olisi tälle ehkä 150-200.
  • Pros: Hyvä tukeva rakenne ja toiminta., Valovoima teoriassa.

Für Vollformat nicht gut genug

Blue-Focus "BF", Amazon
24 March 2011
  • Summary: Auch so eine uralte Objektiv-Rechnung, die längst eine Neu-Konstruktion verdient hätte. Die Lichtstärke ist zwar reizvoll, aber die Abbildungsleistungen und Bildfehler sind es nicht. Der Autofokus ist langsam, laut und rau. Sigma kann das heute zum Glück viel besser.
