Sony 70-400mm f/4-5.6 SSM G (SAL-70400G) - Review / Test Report
30 May 2009
Conclusion: The Sony 70-400mm f/4-5.6 SSM G is an impressive piece of engineering. The resolution figures are very good across the zoom range. Lateral CAs, vignetting and distortions are generally very well controlled and not field relevant. The only real optical weakness of the lens is the quality of the bokeh (out-of-focus blur) at the long end of the zoom range.
