Pixco Adjustable Focusing Helicoid Macro Tube for M42 Mount Lens
Description:
This all-metal adjustable helicoid macro tube is designed for M42 screw-mount lenses. Featuring a built-in precision focusing barrel,. This design not only enables precise manual focusing for specialty lenses lacking a focus ring (such as cine, industrial, or enlarger lenses) but also functions as a macro extension tube. It is a versatile tool for achieving fine focus and magnification control from close-up to working distance.
Key Features & Characteristics:
1. A single rotation allows for fine focus adjustment or magnification change, ideal for professional lenses without a focus ring.
2.Dual Application: As an adjustable focus adapter, it solves the focusing challenge for specialty lenses (e.g., cine lenses, enlarger lenses, industrial lenses). As a macro extension tube, it significantly reduces the minimum focusing distance for high-magnification macro photography.
3.Aluminum Precision Construction: Crafted from precision-machined aluminum with an anodized finish, offering a balance of lightweight strength, ensuring smooth focusing action, precise positioning, and a stable, wobble-free connection.
4.Fully Manual & Mechanical Operation: This is a purely mechanical unit with no electronic contacts. All automatic functions (auto aperture, autofocus) are disabled. Aperture and focus must be controlled manually.
5.Standard M42 Mount Compatibility: Compatible with standard M42×1 screw-mount (1mm pitch) lenses. Suitable for a wide array of manual, cine, industrial, and enlarger lenses utilizing the M42 mount.
Important Usage Notes:
1.Core Functionality: This tube alters the optical flange distance via physical extension to enable manual focusing and macro capabilities. All exposure parameters must be set manually.
2.Operation: Focus (or magnification change) is achieved by rotating the helicoid barrel of this tube. Aperture must be controlled manually via the lens's own aperture ring or preset method.
Compatibility Information:
1.Mount Specification: Standard M42×1 screw mount (1mm pitch).
2.Typical Equipment: Various lenses utilizing the M42 screw mount. This is a lens-to-lens component and does not specify camera body models.
