Tamron's first constant f/2.8 standard zoom with VC stabilisation for full-frame DSLRs.
The Tamron SP 24-70mm f/2.8 Di VC USD (model A007) was released in 2012 as Tamron's professional constant f/2.8 standard zoom for full-frame Canon EF and Nikon F bodies. VC (Vibration Compensation) is built in — the first third-party 24-70mm f/2.8 zoom with optical stabilisation, distinguishing it from the unstabalised Canon EF 24-70mm f/2.8L II USM and Nikon AF-S 24-70mm f/2.8G ED. USD (Ultrasonic Silent Drive) provides fast, quiet AF. The lens covers the professional standard zoom range on full-frame and APS-C bodies.
The optical design uses 17 elements in 12 groups. Nine rounded aperture blades produce smooth bokeh. The 82mm filter thread is the standard for professional third-party f/2.8 zooms. At 825g the lens is moderate for a constant f/2.8 standard zoom with IS. Minimum focus distance of 0.38m. VC provides optical stabilisation for handheld stills and video. USD motor provides fast, quiet AF. Constant f/2.8 aperture throughout the 24-70mm range.
The built-in VC is the A007's defining practical advantage over the major-brand 24-70mm f/2.8 zooms at its release: optical stabilisation extends handheld usability for stills at slower shutter speeds and provides smoother video footage without an IS-equipped 24-70mm alternative from Canon or Nikon. The 24-70mm constant f/2.8 range covers the full professional standard focal length for events, portraits, and editorial. For Nikon F users the Tamron version provides an IS option not available from Nikon.
On the used market the Tamron SP 24-70mm f/2.8 Di VC USD A007 is available at affordable professional zoom prices. Condition checks: VC engagement, USD motor response, zoom ring smoothness, and 82mm front element for marks. The A025 (2017 successor) improved optical performance and the VC system. Confirm the mount version — Canon EF and Nikon F versions are available and not interchangeable. Compatible with full-frame and APS-C bodies in the specified mount.
