Latest Review Posted | HD Pentax-D FA 15-30mm F2.8 ED SDM WR After owning K-5 IIs, and shooting DA 15, DA 21, DA 12-24, Rok 8mm and a number of legacy primes I have found that in comparison the D-FA 15-30 on Full Frame Sensor yields excellent image quality. I have put it to use for occassional Astro Landscapes, and event photography. Although I regularly carry it in my bag, it does not get as much use as say the Ltd primes did simply because of its enormous size. The use of filters makes it even LARGER.

I particularly have appreciated the benefit of the f2.8 aperture, making full use of it during some night sky photos. The following image did not use Astrotracer function https://farm5.staticflickr.com/4424/36055933644_889c0e01b5_c.jpgMilkyway Cascade into a derelict church. by Matt, on Flickr
