Hands-On Review of the Tamron SP 24-70mm f/2.8 Di VC USD Lens for Canon Cameras
The Tamron SP 24-70mm f/2.8 Di VC USD lens for Canon EF mount is a well-performing wide angle to short telephoto zoom lens with a fast maximum aperture. This lens’ focal length of 24-70mm on a full-frame sensor is suitable for most general shooting situations, and with the built-in VC vibration compensation system, it is ideal for low-light shooting.
Also integrated into the design of this lens is the Ultrasonic Silent Drive (USD) autofocus motor, which provides quick, near silent auto focusing that is perfect when shooting video. In terms of optical quality, the SP demarcation means this is part of the Super Performance line of Tamron lenses and features three low dispersion (LD) lenses and two extra refractive index (XR) lenses for sharp images across the entire zoom range. The iris construction is made up of 9 diaphragm blades, resulting in a rounded aperture for producing impressive bokeh effects. While this lens is specifically designed for Canon cameras, it is also available in Nikon and Sony mounts.
