Walimex 500/8.0 DSLR Pentax K

A classic with excellent imaging performance. This lens telephoto lens is quite handy and lightweight despite its length of approximately 300 mm. The design, which uses only 5 lenses in 4 groups, allows for outstanding, color-accurate, and sharp images without disturbing field curvature. The relative aperture of 1:8.0 enables outdoor use, whether for wildlife photography or detail shots in landscapes. The preset aperture feature allows you to set your desired aperture in advance; it can then be adjusted from the maximum opening to the preset value with a quick twist of the finger. The advantage: maximum viewfinder brightness when focusing, and lightning-fast selection of the preset aperture for photography and filming. The attached 360° rotating tripod mount allows for balanced attachment to a tripod and switching between portrait and landscape orientation. The lens works in most cameras in either shutter priority or manual mode. For more details, refer to your camera's manual. T2 connection, usage tip: The T2 adapter is screwed onto the lens, and then the lens is locked in place. The side screws on the T2 adapter allow for "uprighting" the lens after loosening them—aligning the index for infinity or the depth of field marks upwards. Retightening the screws securely holds the lens 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. Using a lens designed for full-frame cameras on an APS-C sensor camera means these areas are not utilized, thus achieving maximum quality. Additional post-processing time for correcting lens errors is therefore eliminated.
