- Three aspherical elements
- Moisture-resistant construction and protective coatings
Designed to maximize the potential of full-frame mirrorless cameras, the Tamron 28-75mm f/2.8 Di III RXD lens delivers high-speed performance in a compact, lightweight frame. The revolutionary RXD motor unit, paired with five optical elements in the body of the lens, delivers fast, clear imagery to your camera with virtually no sound. A moisture-resistant construction and additional coatings on the front and rear elements help ensure your lens stays safe while delivering consistent performance.
Keep it quiet
The Rapid eXtra-silent stepping Drive (RXD) in the Tamron 28-75mm f/2.8 Di III RXD controls the rotational angle of the motor using a precision actuator, directly driving the focusing lens without passing through a reduction gear, making this lens exceptionally quiet and fast — ideal for video or fast-action stills.
Small size, high performance
Weighing only 550g (19.4 oz) with a length of 117.8mm (4.6 in), the Tamron 28-75mm f/2.8 Di III RXD packs a lot of power. One Extra-Low Dispersion (XLD) element and one Low Dispersion (LD) help minimize chromatic aberrations and color fringing, improving color accuracy. Three aspherical elements work together to reduce distortion, improving overall image clarity. The 7.5” Minimum Object Distance (MOD) provides flawless close-up shooting at the wide-angle end.
Protect your shot
Lens surfaces are treated with Tamron’s proprietary Broad-Band Anti-Reflection (BBAR) coating, helping to preserve a crisp image quality while reducing ghosting and flaring. Special moisture-resistant construction as well as fluorine coating further improve the performance of the Tamron 28-75mm f/2.8 Di III RXD, making it convenient to take out into the field as well as use in the studio.
