Verdict

The Pentax Q system is not about DSLR-like image quality but about pushing the miniaturization to the limits. The Pentax-02 Standard Zoom 5-15mm f/2.8-4.5 clearly supports this design approach. Within the limits of its (sensor-)system it is also capable of delivering very good results at that's throughout the zoom range. The sweet spot is around f/4. Diffraction is already limiting the quality beyond so don't get fooled by the mainstream aperture settings that you may be used to from your DSLR. Both vignetting as well as lateral CAs are very well controlled. However, a very heavy amount of barrel distortion at 5mm can be an issue in certain situations.

The build quality is very good thanks to a tightly assembled lens body made of pastic and metal part based on a metal mount. At just 96g it feels somewhat more substantial than the Standard Prime 8.5mm f/1.9 but it's still a dwarf compared to bigger format lenses. The AF is both fast as well as virtually silent. It's also a joy to handle this lens on the Q. We used the combo on a trip to Nepal. Its image quality certainly does not match bigger format systems. However, it was a nice, albeit expensive, set for those occasions where a big setup is simply not appropriate. You may argue that something like a Fuji X10 may also do the job in this case - even with a better image quality. However, the X-10 lacks exchangeable lenses, making it less flexible.
