Sigma AF 135-400mm f/4.5-5.6 APO Aspherical RF - Review / Test Report

photozone.de
5 April 2006
  • Conclusion: The Sigma AF 135-400mm f/4.5-5.6 APO Aspherical RF is not a perfect lens nor can you expect that a budget lens reaches high end quality levels. Nonetheless it is capable to provide very decent results especially in the 135-300mm range. At 400mm @ f/5.6 the quality is quite soft but from f/8 and up the quality is very respectable. The distortion characteristic is almost perfect and vignetting isn't really field relevant on an APS-C DSLR.
