More than just the focal length.

Atypical optical structures not normally present in most camera lenses are required for realism.

Exact nature of these optical structures is highly variable. In my case, the required optics can no longer be purchased. https://www.zennioptical.com/p/rimless-flexible-memory-titanium/2164?skuId=216411 appears to be structurally similar to what is required to achieve maximum realism.
