The following discussion will delve into the specific mechanical and operational distinctions between these two lens mount systems, examining their impact on camera compatibility and user workflow. The focus will be on understanding how these design choices affect practical photography.
1. Aperture Coupling Mechanism
The aperture coupling mechanism represents a pivotal element differentiating the earlier and later Nikon lens mount designs. In essence, this mechanism physically connects the lens’s aperture ring to the camera body, allowing the camera to “know” what aperture is set on the lens. The original design employed a simple prong on the lens that engaged with a corresponding lever on the camera body. As the aperture ring was adjusted, the lever moved, signaling the aperture setting. This system facilitated stop-down metering, where the photographer would manually close the aperture to the desired setting before taking the shot. The later mount improved upon this system, enabling more precise and automated aperture control. A notable example is the elimination of having to manually index the lens when mounted to the camera.
The refinement of the aperture coupling mechanism led to significant improvements in metering accuracy and operational efficiency. The later mount incorporated a stepped aperture ring with a “metering ridge”. This ridge communicated the minimum aperture of the lens to the camera, enabling features like programmed auto and shutter-priority auto exposure modes. In practical terms, this meant that photographers could now rely on the camera to automatically select the appropriate aperture for a given scene, vastly simplifying the shooting process. Without this refinement, achieving accurate exposure in these automated modes would be significantly more challenging, requiring manual adjustment and increasing the potential for errors.
The advancements in the aperture coupling mechanism, especially the integration of the metering ridge, represent a fundamental shift in the design philosophy. These design changes improved usability and expanded the capabilities of Nikon cameras. Understanding the specifics of this mechanism is crucial for photographers seeking to leverage the full potential of both older and newer lenses on a variety of camera bodies. The compatibility implications, driven by these mechanical differences, directly impact lens selection and shooting workflow, influencing the final outcome of the photographic process.
2. Metering Accuracy Improvements
Metering accuracy improvements represent a key evolutionary step in Nikon’s lens mount design, directly correlated with the transition from one mount system to the other. The refinements made in the later design specifically addressed limitations inherent in the earlier system, leading to more reliable and consistent exposure readings across a range of shooting conditions.
-
Introduction of Automatic Maximum Aperture Indexing
The newer system introduced automatic indexing of the lens’s maximum aperture. This eliminates the need for manual lens indexing when mounting a lens onto compatible camera bodies. The camera can automatically recognize the lens’s maximum aperture. This is essential for accurate exposure calculations in aperture-priority and program modes.
