Review: Sigma AF 17-50mm f/2.8 HSM DC EX OS

Skrevet af Noel Christensen i Objektiver, Review

Photozone.de har anmeldt Sigma AF 17-50mm f/2.8 HSM DC EX OS, et objektiv der på rekordtid er blevet et meget populært “upgrade” objektiv, takket være f2.8, billedstabilisering og en række positive anmeldelser.

Photozone.de skriver bl.a.:
Over the recent years Sigma struggled to take off in the fast standard zoom arena for APS-C DSLRs. This segment has been dominated by the Tamron AF 17-50mm f/2.8 (VC) with its highly attractive price/performance ratio and the all mighty but expensive Canon EF-S 17-55mm f/2.8 USM IS owning the quality crown. However, it may make sense to rethink this order of things now – Sigma just released their all new AF 17-50mm f/2.8 HSM DC EX OS. That alone may not be all THAT exciting – we’ve seen many fast standard zoom lenses by Sigma come and go – but this one is a bit more special. Recently Sigma announced a couple of lenses featuring their brand new FLD glass and the new 17-50mm f/2.8 OS is among them. FLD glass has an optical characteristic similar to fluorite glass. Such glass elements can be used to compensate optical aberrations (defects) more efficiently than conventional “special” elements such as Sigma’s more commonly used SLD glass. We were already very impressed by the performance of the Sigma AF 8-16mm f/4.5-5.6 HSM DC which does also benefit from FLD elements so there’s some well founded hope that the AF 17-50mm f/2.8 HSM DC OS stands out-of-the-ordinary as well.
