at first

I’m sorry

Because we can’t speak english

I am using DeepL translate, so it may be a strange sentence,

but I would like you to understand

Thank you

In this issue, we present a lens mount base design for PETRI Camera’s 1970 manual-focus film SLR camera.

PETRI V6-Ⅱ(Reference product)

The lens mount on this body is a PETRI mount.
The mount base is independent of the eye-level finder. The design of the base is straight down, with a slight radius shape and then further down. The design is a bit complicated.

The lens mount base consists of black-colored plastic.

The lens mount is held in place with three screws. The mount itself is a unique lens mount that extends out from the base. The design of the lower part is influenced by the design of the tripod mount on the camera body.

In this issue, we introduced the lens mount base for PETRI Camera’s 1970 release manual focus SLR camera.

PETRI Camera’s V6-II has a unique world view, which we introduced in a previous column, and the lens mount base is also uniquely designed.

I believe that the lens mount and tripod mount are prioritized in the lens mount base.


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!

Thank you again for reading this column.
