The lens is capable to deliver a very high resolution which surely originates in the rather conservative zoom ratio. However, at the wide-end it suffers from very pronounced residual aberrations so you may run into situations where you cannot exploit the potential of the lens. If you´re primarily shooting landscapes with rather long focus distance settings this will not be much of an issue but for at closer settings you should either choose a small aperture (f/11) or do at least a depth-of-field preview check. Other than that the lens performed according to its class. The zoom range isn´t all that attractive on APS-C DSLRs but it may be worth a look for 1.3x or FF DSLRs (not tested in this scope). ]]> Sun, 07 Mar 2010 13:47:47 +0100
