This item is a Canon EF 50mm f/1.8 II lens in very good condition.  Lens glass is clean and clear.  The autofocus works properly.  It fits EF and EF-S cameras.  It comes with a rear lens cap and a UV filter. The two seashell demo snapshots were taken with this lens using the  on camera flash.

Ken Rockwell review.

"This little lens is Canon's biggest secret.

The Canon 50mm f/1.8 II has fantastically good optics, better than Canon's "L" series wide lenses like the 16-35mm f/2.8 L II.

In fact, this $125 plastic lens gives sharper results than the 50mm f/1.4 USM I've used, especially in no light. The f/1.4 is soft at f/1.4, and worse, I rarely get in-focus results with it, while this f/1.8 lens is sharp at f/1.8, and always delivers perfect in-focus results!

The 50mm f/1.8 II weighs less, costs less, and autofocuses more accurately than the 50mm f/1.4 USM."
