Designed for the Pentax K-Af Mount, this 10-17mm offers a zoom function on top of its fisheye capabilities.
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. The zoom ring and focus rings have different grips making it easy to distinguish between them while composing through the viewfinder, but they do feel a bit clunky at the extremes of their range where movement is less than smooth.
This lens doesn’t excel in the image quality stakes but at £399 it’s an affordable option that comes supplied with a built-in lens hood and a lens cap to fit over the top to protect the front element.
