S8109 M48 copper ring suitable for Canon mouth, 10.8mm thickness, copper ring with velvet and matte finish

S8109

screw thread:M48*0.75

thickness:10.8mm

The processing technology of aluminum involves sandblasting and oxidation, which leads to an increase in tolerance during acid etching and oxidation, which is originally a high-precision machining process. Moreover, aluminum is relatively soft and prone to wear, which also leads to large interface tolerances and looseness over time of use.

The new product, Canon interface part, is made of all copper material and nickel plated. Solved the problem of large tolerances in aluminum materials after long-term use or oxidation. Affects the focal plane and optical axis. The M48 port processed with aluminum material at the back reduces weight, lowers costs, and is sufficient for use. Total thickness 10.8mm. Standard intercept.
