This photographic optic is a manual focus lens produced by Nikon, characterized by its 135mm focal length, a maximum aperture of f/2.8, and adherence to the AI (Aperture Indexing) standard. It is designed for use with Nikon SLR cameras that support the AI system, allowing for proper metering with compatible bodies. As a telephoto prime lens, it offers a relatively narrow field of view and facilitates subject isolation due to its shallow depth of field at wider apertures.

Its significance lies in its combination of affordability, sharpness, and fast aperture for the time of its production. It provided photographers with a useful tool for portraiture, sports, and general telephoto work, offering a balance between image quality and cost. Its AI designation is also noteworthy, as it indicates compatibility with the metering systems of many Nikon film cameras from the late 1970s onwards, ensuring proper exposure control. The 135mm focal length is particularly favored for its flattering compression effect in portrait photography.

This refers to a specific lens manufactured by Nikon. It is a telephoto prime lens with a focal length of 135mm and a maximum aperture of f/2.8. The “AIS” designation indicates that it is a member of Nikon’s Advanced Integrated System line of lenses, featuring improved metering compatibility with certain Nikon camera bodies.

Such a lens offers several advantages, including a pleasing background blur (bokeh) due to its wide aperture. This characteristic is desirable for portrait photography and isolating subjects from their surroundings. Its manual focus operation promotes deliberate and precise focusing. Furthermore, its robust construction and optical design have made it a popular choice among photographers for decades, often offering a balance of image quality and affordability in the used market. Its enduring legacy is a testament to its optical performance and build quality.

Adapting older Nikon lenses, specifically those with the AI (Aperture Indexing) mount, for use on Canon EOS cameras, which utilize the EF lens mount, requires an adapter. This adaptation allows photographers to use classic Nikon glass on more modern Canon camera bodies. However, it’s crucial to note that while the adapter physically connects the lens to the camera, it generally does not provide electronic communication.

The primary benefit of this adaptation lies in the potential cost savings and access to unique optical characteristics. Older Nikon lenses, often prized for their build quality and rendering, can be obtained at relatively lower prices compared to newer Canon lenses. Moreover, this allows photographers to experience different aesthetics and lens characteristics, potentially broadening their creative options. Historically, this practice gained traction as photographers sought to leverage their existing Nikon lens collections when transitioning to Canon’s EOS system.

These terms refer to two distinct generations of lens designs for Nikon F-mount cameras. “AI,” standing for Automatic Indexing, was introduced in 1977, representing a mechanical system that couples the lens aperture to the camera’s light meter. An example of a lens featuring this design is a 50mm f/1.4 lens marked with an aperture ring that incorporates a ridge for the meter coupling lever on the camera body.

The “AIS” designation, introduced in 1981, represents an improvement upon the earlier technology. While maintaining the functionality of its predecessor, it offered enhancements in the coupling mechanism and improved metering accuracy, particularly with newer camera bodies. Lenses of this type often feature a stepped aperture ring, facilitating more precise aperture settings and providing better communication with the camera’s metering system. The arrival of this lens mount system allowed for full-aperture metering on compatible cameras, resulting in faster and more convenient operation.
