M42 Macro Extension Tube

Description:
These extension rings allow to make great macro pictures without spending much money. The extensions rings enlarge the distance between the lens and the camera sensor/film. The farther away from the image plane the lens is, the closer the focus and the greater the magnification are.

The set consists of three rings (7mm, 14mm & 28mm), that can be used separately or in any combination. With an additional M42 lens mount adapter the extension rings can also be used with Canon, Nikon, Olympus and other cameras.

Technical Details:
Material: aluminum
Overall length: 49mm

Info:
Focus and aperture have to adjusted manually on the lens. The suitable shutter speed can be selected on the camera.
