Walimex 650-1300/8-16 DSLR Pentax K

A classic with very good imaging performance. This lens telephoto zoom lens is quite handy and lightweight despite its length of about 460 mm. The thoughtful design without a built-in iris diaphragm allows for excellent, color-accurate, and sharp images through the use of 8 lenses in 5 groups. The relative aperture of 1:8.0 provides a bright viewfinder image when used outdoors, even in wildlife photography or detail photography in landscapes. The lens does not have a selectable aperture: the maximum possible opening is always available, and the lens is corrected for this, delivering its highest performance without being diminished by light diffraction at the aperture blades. The initial aperture associated with the respective zoom range is engraved on the mount for reference. User advantage: The mounted 360° rotatable tripod socket allows for balanced attachment to a tripod and switching between portrait and landscape orientation. Approximately 5 m close focus at 1300 mm setting allows nature photographers to choose exciting subjects. The lens works in automatic exposure or manual mode with most cameras. For more details, refer to your camera's manual. T2 connection, usage tip: The T2 adapter is screwed onto the lens, then the lens is locked onto the camera. The side screws on the T2 adapter allow for "uprighting" the lens after loosening - aligning the index for infinity or the depth of field marks upwards. Retightening the screws secures the lens and adapter reliably. Save time in post-processing. Many lens errors such as distortion, edge softness, or vignetting occur in the outer areas of the image. Using a lens designed for full-frame on a camera with an APS-C sensor means these areas are not utilized. Thus, you achieve maximum quality. Additional post-processing time for correcting lens errors is therefore eliminated.
