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 for wildlife photography or detail shots in landscapes. The optics do not have a selectable aperture: the maximum possible opening is always available, and the optics are corrected for this, delivering their highest performance without being diminished by light diffraction at the aperture blades. The initial aperture corresponding to the respective zoom range is engraved on the mount for reference. User advantage: The attached 360° rotatable tripod mount allows for balanced attachment to a tripod and switching between portrait and landscape orientation. Approximately 5 m close focus at 1300 mm allows nature photographers to select exciting subjects. The lens works in shutter priority or manual mode on most cameras. More details can be found in 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 markings upwards. Retightening the screws securely holds the optics and adapter in place. Save time in post-processing. Many lens errors such as distortion, edge softness, or vignetting occur in the outer areas of the image. When using a lens designed for full-frame on a camera with an APS-C sensor, these areas are not utilized. Thus, you achieve maximum quality. Additional post-processing time for correcting lens errors is therefore eliminated.
