Tamron has officially announced its 17-70mm f/2.8 DI III-A VC RXD APS-C zoom lens for interchangeable-mount mirrorless cameras in both Nikon Z and Canon RF systems. The announcement emphasizes availability through B&H, with retail availability stated for July 2, 2026, alongside additional product information from the retailer. The lens targets APS-C sensor models such as Canon’s EOS R7 and EOS R10. Because it is designed for APS-C crop sensors, the lens provides a field of view that corresponds to a 27–112mm equivalent range on a 35mm system. The published information also notes that the lens includes Tamron’s VC (Vibration Compensation) and RXD focusing drive technology, positioning it as a general-purpose zoom with a constant f/2.8 aperture across the focal range. Coverage from both sources aligns on the lens model name, the dual-mount support (Canon RF/RF-S and Nikon Z), the APS-C positioning, and the stated July 2 release date and retailer listing.
