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.
Sony 11-18mm f/4.5-5.6 DT ( SAL-1118 ) - Review / Test Report
11 March 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.
