About copy-to-copy variation - thxbb12 - 12-12-2021

Hello everyone,

I found Roger Cicala's remark about copy-to-copy variation quite interesting while reading this article on lensrentals.com:

"Micro 4/3 lenses, in general, have a lot of sample variation. Why this is I can’t say. What I can say is it’s not the fabled “they need to up their QA check” that people imagine happens. Micro 4/3 lenses, as a rule, don’t have any compensating adjustable elements, so what you get at the end of the assembly line is what you get unless something is broken inside."

We often hear that XYZ manufacturer has to up their game in term of quality control. However, it appears that might not be the issue at hand.
