Excerpt: The lens gives a viewing angle of 1800 at 10mm and 1000 at 17mm and being a DA format lens this equates to a 15mm-25.5mm full-frame equivalent. The lens also offers extra-low dispersion glass elements to help reduce chromatic aberration, on top of which there's an SP (Super Protect) coating to make cleaning the lens's front element easier. The build itself is of good quality, featuring both metal and plastic parts, together giving it a refined feel and solid weight.
Pentax SMC DA 10-17mm f/3.5-4.5 ED[IF] Fisheye - Review / Test Report
31 October 2008
Conclusion: Fisheye lenses are never really perfect performers. However, these are special effect lenses where sheer quality is more a secondary aspect anyway. The Pentax SMC DA 10-17mm f/3.5-4.5 ED[IF] Fisheye is certainly sharp enough for its purpose and the high degree of barrel distortion is naturally a feature to enjoy and not a bug. However, the Pentax lens clearly has some downsides. The bokeh (out-of-focus blur) is very harsh - see e.g. the "horse" sample image above.
