Sharp, fast and silent focusing

Pros:-Internal focusing-Sharp edge-to-edge-About as ultra-wide as you'll get without ultra

Quiet, fast auto-focusing

Very fast auto focus.

This lens produces amazing tack-sharp images, has great image stabilization, and fast focus

What I found:*Easy and smooth zoom, and manual focus.

There are much better options such as the 10-22, or the great ef-s 17-50mm

Clear, crisp and sharp as s tack
