Haoge Macro Focus Lens Mount Adapter with Focus Helicoid for M42 42mm Screw Mount Lens To M42 42mm Screw Mount Built-in Camera, 17mm-31mm

Manual Lens Adapter with Helicoid Macro Tube for M42 42mm Screw Mount Lens to M42 42mm Screw Mount Camera Body. The macro feature of this adapter provides a focus helicoid that extends the distance from the lens to the sensor, allowing you to focus closer than the lens itself would normally allow. This means you get macro performance without switching to a dedicated lens, and you retain all the normal benefits of the optics even when you're not using the macro capabilities. When fully extended, it allows for easier close-up/macro image capture, and of course, it allows for infinity focus when closed. This helicoid tube is 17mm (min) to 31mm (max) in length, providing a total of 14mm of travel for focusing your lens.
