Description

For your attention:

The black paint finish on the lens is intentionally designed to replicate the retro 1950’s painting technique, achieving a nostalgic style. Over time and with usage, it is expected that the black paint will naturally wear off, revealing the copper material underneath, creating a unique aged look.
The paint flaking off is part of the intended design and contributes to the vintage aesthetic of the lens.
