Best Q lens so far.Virtually no barrel distortion, which is an issue with other Q lenses. Sharp across the frame and a very wide zoom range.

This fills out my Q kit nicely - I love taking wide shots of landscapes or architecture and this lens fits the bill perfectly. It's slightly wider in diameter than the other lenses like the 02 or 06, but not by much. More importantly, this lens is very sharp and has great color.

Wonderful quality lens for Pentax Q, as are 02 and 06. Pentax Q is not a toy, it can shoot RAW and or JPG, is extremely light to carry around and images from all above lenses can be of competition standard. Ideal for Street Photography, Travel and Landscape.

It's a great, sharp, fast lens for Q system cameras. Exactly what I wanted. It is VERY wide angle ... just short of fish-eye, so be sure that's what you really want.

Best lens in the Q lineup........super nice for both video and photos- must have lens if you're a Q shooter! Brilliant colors and sharpness as well as nice small size with autofocus, near perfection!

I've only been playing with the lens for a little bit and I am very impressed with it's sharpness and general image quality! The lens can resolve very fine facial details like eyelashes and hair.

When this lens first came out, I balked at purchasing it due to the price. I eventually weakened and I'm glad I did. This is a great lens and a fantastic addition to the Q.

This lens works well even if it is optically a bit slow.The price is a wee bit high but it is the only ultrawide for the Q system.Images taken are sharp and clear with good detail and color.Focus is fast and accurate.Much better images than the 3.8mm CCTV lens I was playing with.
