Mini reviewPrime lenses aren't as flexible as zooms, but offer faster maximum apertures and should bring better image quality.

Mini reviewOffering a 22.5mm effective focal length on a Pentax D-SLR body, the 15mm f/4 gives a wide angle of view.
Pentax already has a 100mm macro option in its range - the Pentax smc D FA 100mm f/2.8 Macro - but this newer version has the advantage of weather resistance.
The Pentax 12-24mm has a big price tag but is compact and lightweight. The big zoom ring facilitates smooth zooming with an even progression from start to finish. The focus ring is equally smooth but has a longer travel than most ultra-wide competitors
The smallest and lightest in the group, the Pentax 18-55mm looks more like a standard 50mm prime lens than a zoom. The filter size is refreshingly small at 52mm, although the lens is reasonably fast at f/3.5-5.6
