Tamron has announced a new firmware update for its 25-200mm f/2.8-5.6 Di III VXD G2 (Model A075) lens released last year that does something very unusual, it significantly improves close-focusing performance at the wide end of the lens. The new firmware, version 3.00, improves maximum magnification across the 25-70mm focal length range to reach 1:2 magnification, or half-macro, performance. So while lens firmware updates can change a lot about how a lens performs, significant changes to close-focusing capabilities are highly unusual. The new firmware update is available now through the Tamron Lens Utility app for Windows and macOS. The Tamron 25-200mm f/2.8-5.6 Di III VXD G2 (Model A075) lens is available for Sony E-mount cameras now for $899.
