  • *****
  • Stunning wide angle with minimal distortion

  • February 09, 2010
  • By:

I waited 9 months for this lens to roll off the assembly line for Pentax in Canada, and it was well worth the wait. Crisp, sharp images with minimal CA's vingetting, fast focus and accurate color transmission. This lens is ideal for landscape shooting and dramatic forced perspective images, and the ability to fasten screw on filters is superior to internal filters. With this much of a wide angle, lens flare can be an issue because of the convex front element, this is a common theme with super wide angle lenses. I have used this lens with success at the following events: -Weddings -Trade shows -fashion shoots -studio sessions -photowalks -landscape and cityscape excursions, including night shots -community events Reasonably priced, and able to deliver stunning perspectives, a must have lens for any serious hobbyist or pro-am shooter. Also available for Nikon and Canon
