USD 75...

From what I understand of the, cheaper than dirt Yongnou lenses the optics
are all plastic. However, if that works for you $75 is a bargain.

They talk about 'coating technology' so some of the elements are
presumably glass. They also give the MTF curves.

It should be glass since they usually base their lenses on some legacy
design, if I've understod things correctly and to then use another
material in the optics than the original would be fatal. Diverting from
the original glass composition could be an explanation why knockoffs
rarely measure up to the originals.
