Aperture ring for Takahashi Epsilon 130

This aperture ring can be used to replace (or added) to the original Takahas

This aperture can be installed instead of (or in addition to) the original Takahashi retaining clips (actually: safety tabs) on the Epsilon130.
The perfectly circular aperture means that there are no more diffraction effects from the retaining clips.
Installation is uncomplicated, the hole patterns match the original screw positions exactly and the original screws can be used.
The original rubber plates for buffering are also retained.
Installation instructions will be coming soon!

Of course, you can have the diaphragm installed by us when you purchase the Epsilon130; we charge an opticians hour of 120.- € for the installation.
The adjustment will be checked, but remains basically unaffected.
