Sigma AF 180mm f/3.5 EX HSM APO macro - Review / Test Report
30 October 2008
Conclusion: The Sigma AF 180mm f/3.5 EX HSM APO macro is a very capable macro lens with very high resolution figures, marginal vignetting and non-existing distortions. Unfortunately CAs are a on the high side which is unusual for a tele fix-focal lens - this is a correctable issue though (via PS ACR, RawShooter, etc.). The build quality is very high and thanks to HSM the AF operates pretty fast and virtually silent.
