Pentax SMC DA 10-17mm f/3.5-4.5 ED[IF] Fisheye – Review / Test Report by photozone.com

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. A real problem of the lens are lateral chromatic aberrations (color shadows) and, more so, purple fringing (color blooming). Lateral CAs can be reduced but this is barely possible with PF. Normally I’d say that the degree of PF is a show-stopper but a fisheye isn’t a normal lens anyway. Compared to similar products such as the Nikkor AF 10.5mm f/2.8 DX or Olympus Digital Zuiko 8mm f/3.5 the price of the Pentax lens is very attractive at around 550€/US$. However, if you’re split between a fisheye and a corrected ultra-wide lens you should probably still prefer the latter – fisheye lenses are really specialty items. That all said, it is lots of fun to go out there and play with the Pentax SMC DA 10-17mm f/3.5-4.5 ED[IF] Fisheye
