Is there any difference between a 75mm 3.5 OPTON TESSAR on a ROLLEIFLEX vs IKOFLEX?

This author suggests that many of the early West German lenses marked "Zeiss Opton" were of poor mechanical quality.

The author refers to CONTAX lenses. The current subject is IKOFLEX lenses which do not have focusing rings. All of my research suggests that lenses such as 75mm 3.5 OPTON TESSAR are of excellent build and optical quality.

The author was complaining about Zeiss Opton products and, in particular, their poor mechanical build quality. All lenses have both optical and mechanical components even if they don't have a focusing ring.

Further research has revealed that OPTON are better build quality due to JENA having been made from aluminum rather than plated brass. I rest my case.
