objektivfäste

Objektivfäste, often referred to as a lens mount, is the standardized interface that connects a lens to a camera body. It is a critical component that ensures both mechanical and electrical connection, allowing for the transmission of light and data between the lens and the camera sensor.

There are various types of lens mounts, each with its own specifications and compatibility. Some are proprietary to specific camera manufacturers, while others are designed to be more universal. The design of a lens mount dictates the physical dimensions, including the diameter of the mount and the flange focal distance, which is the distance from the lens mount to the image sensor.

Key aspects of an objektvfäste include its bayonet or screw-in mechanism for attaching the lens, the electrical contacts that facilitate communication for autofocus, aperture control, and image stabilization, and the sealing to prevent dust and moisture ingress. Different mounts offer varying levels of compatibility with older or newer lenses, sometimes requiring adapters. The evolution of digital photography has led to the development of numerous lens mounts, each aiming to balance performance, size, and interoperability.
