Item Description
To achieve a 1:1 life-size macro reproduction ratio with the classic vintage Tamron Adaptall-2 SP 90mm f/2.5 manual focus macro lens (Models 52B / 52BB), you need an extension tube. By itself, the native lens only focuses down to a 1:2 (half life-size) magnification ratio.
Key Features
- Model Name: Tamron Extension Tube 18F (specifically designed for the 90mm f/2.5 SP).
- System Integration: It uses the native Tamron Adaptall-2 mount system. You insert the 18F tube directly behind the lens, and then attach your specific camera system’s Adaptall-2 mount adapter behind the tube.
- Physical Build: Features a premium all-metal black body construction.
- Optics: It contains no glass elements, meaning it increases magnification without degrading the superb optical quality of the lens.
- Aperture Linkage: It maintains the mechanical linkages required to control the aperture diaphragm properly through your Adaptall system.
