Cons: What I don’t like: - APS-C only lens. - Extreme edges are un-sharp with visible distortion on my lens, but I’ll admit I like the effect in some images. - The manual focus ring is “grainy” in feel with a considerable amount of friction when turning. - It’s a lot larger than Pentax’s newer DA 15mm F4 Limited lens. - Lens flare without the hood isn’t difficult to produce. - The 6 flat aperture blades can produce quite visible hexagon shaped bokeh bright spots at times. - Not specifically designed to be WR (weather resistant), so it could use an engineering refresh from Pentax.
Pros: What I like: - Seriously excellent at limiting chromatic aberration! - Seriously excellent sharpness, especially at MTF! - Quick-shift focusing ability without having the focus ring turn when AF is happening. - 14mm on APS-C is a nice focal length - Close focus ability - Use as a Rectilinear wide angle landscape lens is top notch. - A nice large f2.8 aperture that produces sharp images on my K-7 from f2.8 onward, however with visible vignetting comparing f2.8 to say f5.6 that I have noticed with limited testing so far. - Produces “star burst” style light sources. - Solid all metal barrel construction. - The bokeh in general is pleasing to my eyes around 80% of the time.
Summary: 14mm is a standard “ultra wide” angle lens for APS-C cameras. What sets this lens apart from many is that it has a reasonably large aperture of f2.8 which is generally a stop or two faster than many other wide angle lenses of a similar focal length. That larger aperture shows in the physical dimensions and weight of the lens, yet it’s far from unmanageable and I think matches quite well with K10D, K20D, K-7(5) camera bodies, especially when they have a grip attached.
