The Canon EF 16-35mm f/4L IS USM Lens is a highly-rated ultra wide-angle zoom lens with excellent sharpness, with the benefit of image stabilization (which the much more expensive f2.8 lens doesn't have). This lens also has internal zoom, so the lens barrel does not extend. Other specs include 3 aspheric & 2 UD lens elements, 9-blade aperture for good bokeh, ring USM for fast autofocus and full-time manual focus. Filter size is 77mm and weight is 615g/21.7 oz. Lens was purchased used from Kerrisdale Cameras in September 2024 (it was $900 + taxes) and is in great condition. I think the photos show that. Includes the original lens hood, caps, soft lens pouch and the box. I am in North Vancouver (Lower Lonsdale) but work downtown near the Art Gallery and could meet near there on weekdays (daytime) if that is more convenient.
