Pentax SMC-FA 20-35mm f/4 AL - Review / Lab Test

31 October 2008
  • Conclusion: The Pentax SMC-FA 20-35mm f/4 AL is a very good lens but it doesn't really offer much over its successor - the SMC DA 16-45mm f/4 ED AL. Similar to its cousin it has one primary problem: lateral CAs (color shadows at harsh contrast transitions) at 20mm. Other than that the lens is capable to produce a very good resolution and comparatively low distortions and vignetting. The build quality is about average for a consumer grade zoom.
