Excerpt: On Pentax D-SLRs, this DA 10-17mm lens has a comparable 35mm focal length of 15-25mm. But, unlike the other ultra-wide zooms on test, this is a true fisheye lens with uncorrected optics that can deliver a 180Âº field-of-view at 10mm. This also means that the image is heavily distorted, bending both horizontal and vertical lines, but the circular image that the lens captures fully covers the sensor.
