10 glass elements in 7 groups (includes two elements with three aspheric
surfaces)

At the cost of achromatic aberrations, which you don't know, are corrected
by a pre-stressed plastic lens.

Even the finest lens systems fall victim to AA. They are a defining quality
factor for refractors and binoculars, but not much of an issue for consumer
level digital cameras.
You've clearly shown everyone what an idiot you are.

Congrats!
