Good build quality (metal, but not weather

Good build quality (focus ring is tight and not flimsy)

It is a very well built lens and works great

The lens feels well built and it's got some nice weight to it.

Sturdy build

Solid build and feels expensive

Excellent build and quality.

The image quality is fantastic, it's well built (and not too large/heavy) and that front element always gets some appreciation if you show it around!

The mechanics of the entire lens really gives the impression of quality just as much as the more expensive L lenses but in a plastic body of course.
