What does the M-12 mount require for focusing?

The M-12 mount requires manual adjustment for focusing. This type of mount is designed to provide flexibility in terms of focus control, allowing users to manually adjust the focus as needed for their specific application. Manual adjustment is essential because it gives operators the ability to achieve precise control over the focus point, which is critical in situations where different distances or object details are involved.

This focusing method is particularly relevant in applications such as surveillance, machine vision, or any situations requiring fine-tuning to ensure image clarity. Unlike automatic focusing systems, which rely on electronic signals or features to determine focus, the M-12 mount emphasizes user input and discretion for achieving optimal focus settings.

While interchangeability of lenses and fixed distances can play roles in certain scenarios, they do not fundamentally dictate the way focusing is achieved with the M-12 mount. Additionally, a specific outer thread diameter pertains to the physical compatibility of the lens with the mount rather than focusing itself. Thus, manual adjustment captures the essential operation required for optimal usage of an M-12 mount.
