Lens Test: Sony 11-18mm f/4.5-5.6 DT AF
27 June 2009
Excerpt: The widest lens available for Sony's Alpha 100 DSLR, this digital-only (DT) zoom, the 11-18mm f/4.5-5.6 AF ($580, street), isn't recommended for use on older Konica Minolta Maxxum film cameras. But Alpha users may love its 16.5-27mm equivalent focal length, even if that is a narrow range by today's standards.
Sony 11-18mm f/4.5-5.6 DT ( SAL-1118 ) - Review / Test Report
31 October 2008
Conclusion: Similar to its Tamron sister lens the Sony 11-18mm f/4.5-5.6 DT does not convince. At 11mm the critical corner performance is absent and the hefty amount of CAs and pronounced distortions don't make things any better here. The situation is better at 14mm and 18mm but then you don't really want to invest into an ultra-wide zoom lens just to enjoy the performance at the "long" end of the zoom range.
Summary: A capable wide-angle zoom lens for Sony's Alpha DSLR-A100 camera.Sony's DT 11-18mm super wide zoom lens represents a minor evolution of the 11-18mm lens released by Konica Minolta in mid-2005 for the Dynax 5D and 7D cameras. Its DT design is ideally suited for the APS-sized CCD imager of these now defunct models - and also for the Sony Alpha A100 camera.
