An older Canon vast angle zoom, predecessor of the 16-35 (this one is a little smaller sized and lighter).
As you could view, it's had some wear and tear, and aside from a little dust and the filter ring being every so a little loosened, the glass is clean. This lens is totally functional and takes great images. L series lens, constructed like a storage tank.
It's sharp in the center at 2.8, stopped down it's strong around. AF, button, zoom and emphasis rings work as anticipated. Takes 77mm filters.
Possesses front and rear caps.
$600 OBO or profession (vintage glass, Sony FE), pick-up at yonge and eg.
