A classic with very good imaging performance. This lens telephoto zoom lens is quite handy and lightweight despite its length of approximately 460 mm. The thoughtful design without a built-in aperture 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, making it suitable for wildlife photography or detailed landscape shots. The lens does not have a selectable aperture: the maximum possible opening is always available, and the lens is corrected accordingly. It delivers its highest performance without being diminished by diffraction at the aperture blades. The initial aperture corresponding to the zoom range is engraved on the mount for reference.

A benefit for the user: The attached 360° rotatable tripod mount allows for balanced attachment to a tripod and easy switching between portrait and landscape orientation. With approximately 5 m minimum focusing distance at 1300 mm, nature photographers can select exciting subjects. The lens operates in aperture priority or manual mode on most cameras. For more details, please refer to your camera's manual.

T2 connection, usage tip: The T2 adapter is screwed onto the lens, and then the lens is connected to 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 markers upwards. Tightening the screws again securely fastens the lens and adapter.

Save time in post-processing. Many lens errors such as distortion, edge softness, or vignetting occur at 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. This way, you achieve maximum quality, eliminating the need for additional post-processing time to correct lens errors.
