Tamron's G2 professional standard zoom — rivals Canon/Nikon OEM 24-70mm f/2.8 with VC stabilisation included.
The Tamron SP 24-70mm f/2.8 Di VC USD G2 (model A032) was released in 2017 as the second-generation version of the A007, with improved VC (Vibration Compensation), updated optical formula, and eBAND coating. At 905g it is heavier than the original A007 (825g) — reflecting the redesigned optical and mechanical formula — and provides improved wide-open performance and faster VC operation. The 'G2' designation indicates the second-generation design. Available in Canon EF and Nikon F versions.
The optical design uses 17 elements in 12 groups. Nine circular aperture blades produce smooth bokeh. The 82mm filter thread is the professional f/2.8 standard zoom size. At 905g the Canon EF version is heavier than most competing 24-70mm f/2.8 designs. Minimum focus distance of 0.38m. The second-generation VC provides approximately 5 stops of compensation. USD motor provides fast, quiet AF with full-time manual override. Moisture-resistant construction is built in. Constant f/2.8 aperture throughout.
The G2's practical improvements over the original A007 are the enhanced VC system (approximately 5 stops vs the original's 3 stops) and the eBAND coating for reduced flare at wide apertures. For photographers who want a VC-equipped Canon or Nikon F-mount 24-70mm f/2.8 zoom, the G2 provides substantially better stabilisation than the A007 at a modest premium. The brand-native alternatives (Canon EF 24-70mm f/2.8L II USM, Nikon AF-S 24-70mm f/2.8G) lack optical stabilisation at the same price tier.
On the used market the Tamron A032 G2 is available at mid-range professional zoom prices. Condition checks: VC engagement and stability performance, USD AF response, zoom ring smoothness, and 82mm front element for marks. Confirm the mount version — Canon EF and Nikon F are both available. Compatible with full-frame and APS-C bodies in the specified mount.
