The connection focal length 55 mm from the 18-55mm lens compared to the 55-300mm is not consistent. The image sections agree to some do not match - only which of the two lenses is now "too much" or "too little" picture Section provides ...? Is also Wurscht - otherwise, the zoom lens is fine, the simultaneous images are compared to the 18er, I think, a very small tick color stronger, more luminous. What is missing is a strong supplement to light intensity, but because you frequently rumeiert with 800 or even 1200 ISO. But my K200D comes so amazingly well clear - so far anyway. A pro sees maybe different, but for me it is ok. Well, the physics can not übertrixen halt and the technical solution of a 500mm long tube with a manhole cover large front door can not and will not drag each and pay. From this viewpoint, from me it 4.5 stars for the Zoomschätzchen. Ah yes, the blue-violet seams in stark contrast edges dominates my age-old 300-Zoom quite great! The Pentax 55-300mm not! Less color in this case is more ... Pentax 55-300mm / 4.0 to 5.8 ED Lens for Pentax
