What does ‘AM’ mean in Nikon lenses?
The ‘AM’ designation in Nikon lenses stands for ‘Aperture Memory’ or ‘Aperture Recall.’ It is a feature that allows the lens to store the aperture setting when the lens is not attached to a camera body or when the camera is turned off. This feature is particularly useful for photographers who frequently switch between different lenses or camera bodies, as it ensures that the aperture setting is retained and can be easily recalled when the lens is reattached or the camera is turned back on.
The ‘AM’ feature is commonly found in Nikon’s manual focus lenses, particularly those from the older AIS and AI-S series. However, it’s essential to note that not all Nikon lenses have this feature, and its availability may vary depending on the specific lens model and series. Understanding the ‘AM’ feature can help photographers make the most of their Nikon lenses and streamline their workflow.
How does the ‘AM’ feature work in Nikon lenses?
The ‘AM’ feature in Nikon lenses works by storing the aperture setting in a mechanical memory mechanism within the lens. When the lens is not attached to a camera body or when the camera is turned off, the aperture setting is retained in this memory mechanism. When the lens is reattached or the camera is turned back on, the stored aperture setting is recalled, and the lens returns to its previous aperture setting.
The ‘AM’ feature is typically activated by a small lever or button on the lens, which is used to set the aperture. Once the aperture is set, the ‘AM’ mechanism stores the setting, allowing the lens to recall it later. This feature is particularly useful for photographers who work in environments where they need to frequently switch between different lenses or camera bodies, as it saves time and ensures that the correct aperture setting is always used.
What are the benefits of the ‘AM’ feature in Nikon lenses?
The ‘AM’ feature in Nikon lenses offers several benefits to photographers. One of the primary advantages is that it saves time and streamlines the workflow. By storing the aperture setting, photographers can quickly switch between different lenses or camera bodies without having to worry about adjusting the aperture each time. This feature is particularly useful in fast-paced shooting environments, such as sports or wildlife photography.
Another benefit of the ‘AM’ feature is that it ensures consistency in aperture settings. By recalling the stored aperture setting, photographers can maintain a consistent look and feel in their images, even when switching between different lenses or camera bodies. This feature is particularly useful for photographers who work on projects that require a consistent aesthetic, such as commercial or portrait photography.
