nice little lens from Pentax with very small and compact size.
4 June 2013
Summary: Nice small and compact lens for landscape shooting. I use this lens to shoot outdoor landscape and it came out really nice when I make the photo into HDR. 10mm shot was awesome to bring the whole view in. Must have for those into landscape photography or night photography like start trail.
Summary: Lens quality is on par with Pentax DA (non L) kit lenses. The only difference is it's heavier (probably because of the huge front element and metal built-in lens hood), and it focus' internally. I had never used a fisheye/ultrawide angle lens before this one, so I don't know what to look for comparatively regarding image quality. My eye thinks the IQ is great. There is some purple fringing towards the edges of the image, but I hear this is normal with fisheyes.
