This manual focus wide angle lens for APS-C format cameras, offers a fast angle of view equivalent to a 15mm lens, with a relatively fast maximum aperture of f/2.8 for a budget launch price of around £429.

I like this lens a lot as an artistic tool. It is great for interior shots. Good for wide landscape, and adds a creative compositional view of close work. It is manual focus but the pentax lets you know when you have hit your mark. I usually use a tripod with this lens.

Although it's manual focus, if your using it as a landscape lens take the time to get exact focus because this lens is extremely sharp.. Not recommended for full frame cameras because of bad vignetting. Love it on the 7D2 though

This is a great ultra wide angle lens, feels very solid and pictures turn out very crisp. I currently use it on my d7100 and it works great!
