Canon 70-200mm f/4 L USM Lens Review

Updated Mar 31, 2006

Canon's 70-200mm f/4 L is a medium focal length telephto zoom lens. Due to the focal length and f/4 maximum aperture this lens requires a good amount of light for sharp handheld photos. Fortunately it's very sharp when used wide open at f/4.

Because depth of field is relatively narrow at 200mm and f/4 this lens does a good job of blurring backgrounds and makes a nice lens for portraits.

This lens performs very well with a 1.4x extender. I haven't tried it with a 2x extender but in general a 2x extender will noticebly degrade the image quality of a zoom lens.

I frequently use a 62mm Nikon 6T closeup lens with the 70-200 f/4 L for macro photographs. While not at quite the same level as a dedicated macro lens, this setup yields excelent quality images. A 67mm to 62mm step-down ring is used to attach the Nikon 6T to the lens. Despite the use of the step-down ring I've seen no vignetting in any photos taken with this combination.

If you need a 70-200mm lens and don't need f/2.8 or IS, get this lens.
