Quality glass

Google the lens make & model along with the word 'review'. Such as OptiPoor 5-1000mm F/1.2 Review.

I googled this. Guess what was the only result...

Yep. It directed me to this thread.

I mean you can tell a "good quality lens" simply by taking some pictures with it and seeing if everything comes sharp. And you can hold it and play with it and see if it feels smooth.

You can tell a good lens without ever using it, by looking at the lenses modular transfer function chart and reading technical reviews.
Camera Lens Quality: MTF, Resolution & Contrast

In short, price. But better equipment doesn't equal better photography. It just equals a better tool. The quality of the photography still depends on who's using the tool.

+1 ^^

A bare bones answer is a lens with a constant aperture of 2.8 or wider (with the exception of the large primes which may begin at 4.0).

A classic design.

I don't know if I would call it classic. based on the specs, I think there's some artificial distortion on that top number.

I did say a classic design.
