Pentax SMC-FA* 80-200mm f/2.8 [IF] ED - Review / Lab Test Report
31 October 2008
Conclusion: The Pentax FA* 80-200mm f/2.8 [IF] ED is a very good large aperture tele zoom lens. The resolution figures are generally excellent in the center whereas you need to stop down somewhat to reach the maximum quality at the borders (80mm and 135mm). Both distortions and CAs are negligible in field conditions. The vignetting could be a little better at 200mm @ f/2.8 but it's well controlled otherwise. Typical for a professional grade lens the build quality is excellent.
