A telephoto zoom, the focal length moderately to my standard Kitzoom connects (Pentax SMC DA 18-55mm F3.5-5.6 AL WR Lens (52mm filter thread)) and represents a journey with this friendly combination - without breaking the budget. The offered image quality pleasantly surprised me: resolution and contrast even at full aperture quite useful in one or two steps dimming the subjective impression of sharpness puts to again and is really blameless. (Strictly speaking, the appearance seems more tuned for crisp contrast than the finest resolution, but the images appear to the edge sharp, and that's what counts in the end.) Particularly encouraging: At least I do not have the typical for many telephoto zoom Focus-sagging for must determine Endbrennweite, which means that the 300mm are actually usable! Reflex inclination in backlight? - ME underperformed (probably thanks to effective remuneration and not overly complex design). Distortion and vignetting would certainly lower with good fixed focal lengths, but at this zoom range and compactness of this there is also as little to complain about, especially since both are corrected in Lightroom quickly. A similar situation exists with the chromatic aberration from (chromatic aberration), which are quite well corrected for a zoom of its kind and hardly noticeable in practice. Even the quality at close range is impressive, very nice for cropping details; for the light intensity and only six diaphragm blades decent bokeh; the lens focuses from 1.4 meters, so that the long end of a magnification ratio of 1 at least: 3.6 is achieved. The criticized by some testers oh-so-slow rods autofocus working on my K-7, provided reasonably good lighting conditions, and astonishingly accurate when the lens does not have to drive all the distance range, and sufficiently fast.

The amended convinced bayonet metal, plastic tube, but meticulously crafted (not shaking). Unlike many competitors, the lens straight guide shall be called, the front lens does not rotate when focusing with (important when, for example is happy to work with polarizing filters); a practical sun visor is included. Why a star deduction? Almost picky: early opening could be larger (more reserves in low light conditions and fast action), splash protection as in the long-WR Kitzoom (Pentax SMC DA 50-200mm / F4-5.6 AL WR Telephoto zoom lens) would be nice. This low-cost, ultra-compact alternative However, it has the longer Endbrennweite and, after all, what is to be read in reputable testing, also in terms of image quality well ahead. Price relation is the extent 55-300er absolutely fine - Recommended!
