but I would like you to understand

Thank you

In this issue, we will look at the lens mount base design of a manual focus film SLR camera released in 1987 by CONTAX.

CONTAX 167MT (Reference product)

The lens mount on this body is a Y/C mount.
The mount base is designed to descend diagonally from the same line as the eye-level finder to the outer diameter of the lens mount, and then diagonally back again in the direction of the extension of the initial starting point, with the underside also using many gentle curves.

The lens mount base consists almost entirely of the eye-level finder. It has a release button used to remove the lens and a depth-of-field preview button.

The lens mount is secured with four screws. A coupling lever for programming is also included.

In this issue, we introduced lens mount bases for Contax manual focus SLR cameras released in 1987.

In the 1980s, many of the lens mount bases for SLR cameras were similar to those of the 1970s, using large curves and ovals.

This 167MT is a lens mount base with an excellent Porsche Design design.


I will continue to write columns on the lens mount base design of film SLR cameras and other areas of interest, so please look forward to them!
