28-75mm F2.8 Di III RXD
Model A036
Express your vision in intimate detail
An f/2.8 high-speed zoom made for full-frame mirrorless
Bring your subjects to life with higher resolution and softer defocusing
Packing cutting-edge technology into a compact body, Tamron has created a high-speed zoom lens specifically designed for mirrorless cameras: the 28–75mm F/2.8 Di III RXD (Model A036). A great addition to the Sony E-mount, the A036 strikes a beautiful balance between vibrant image quality, superb bokeh, compact size and lighter weight.
Specialised glass elements throughout control various aberrations and produce stable resolution across the entire zoom range. All the lens surface is treated with Tamron’s proprietary BBAR (Broad-Band Anti-Reflection) Coating, which dramatically reduces ghosting and flaring while preserving crisp image quality. The A036 also incorporates an all-new high-speed precision AF drive system with an RXD (Rapid eXtra-silent stepping Drive) motor unit that is remarkably quiet.
In addition to portraits, nature shots and street photography, the 0.19m Minimum Object Distance (MOD) lets you enjoy new forms of photographic expression with close-up shooting at the wide-angle end. With Moisture-Resistant Construction and Fluorine Coating, this lens offers exceptional mobility and outdoor functionality. It is the only zoom you need to portray the world in all its full-frame beauty.
Focal length: 29mm | Exposure: F/2.8 | Shutter: 1/80sec | ISO: 100
Outstanding image quality meets delicate bokeh
The A036 zoom delivers a dazzling balance of clear yet soft rendering, stunning bokeh and exceptional resolution for in-focus areas. It also captures the finer details across the entire focus plane with performance that supports the latest high-resolution cameras—all while expressing the characteristic smoothness of a fast aperture lens.
Stunning bokeh spreads gently from the plane of focus to highlight your subject. By stopping down the aperture, you can alter how images are rendered. The lens also incorporates a nine-bladed aperture that produces beautifully round defocused light points. And Tamron’s distinctive image characteristics, which produce more than just a different degree of blur with F-stop changes, add even more impact. The A036 zoom is designed to maximise the potential of full-frame mirrorless cameras. Because it is designed to be your most frequently used high-speed zoom, we made it compact. Now you can enjoy advanced optical performance in a compact size with lightweight convenience. Weighing just 550g (19.4 oz) with a length of 117.8mm (4.6 in), the A036 lets you take advantage of the mobility offered by mirrorless cameras for everything from everyday snaps and commemorative photos to specialised photography.
Get an MOD of 0.19m at a wide-angle setting
The Model A036 breaks all the rules regarding MOD. No longer must the MOD of a zoom lens be fixed throughout the focal range. The A036 reaches a MOD of 0.19m (7.5 in) at the 28mm wide-angle end achieving a maximum magnification ratio of 1:2.9. A working distance of just 5.7cm (2.24 in) from the front element allows you to shoot close-up with a sense of perspective unique to wide angles. At the 75mm telephoto end, the 0.39m (15.3 in) MOD provides an image magnification of 1:4, allowing close-up shooting with a pleasantly blurred background similar to a macro lens.

Superb AF keeps it sharp and quiet
The AF drive on the A036 includes an RXD (Rapid eXtra-silent stepping Drive) motor unit to help you stay focused on the action. RXD uses an actuator to precisely control the rotational angle of the motor, allowing it to directly drive the focusing lens without passing through a reduction gear. A sensor that accurately detects the position of the lens enables high-speed and precise AF, which is ideal when shooting continually moving subjects or video. With a focusing system that is both smooth and quiet, the A036 lets you shoot a video without worrying about picking up ambient drive sounds.
Designed to be your go-to lens
The A036 zoom features our new “Human Touch” design, a mixture of form and function embodied by the “Luminous Gold” brand ring above the lens mount. It tells you that no detail has been overlooked in creating a design and feel that’s easy to work with—everything you look for in a photography partner. And everything you expect from Tamron.
Built with Mirrorless in Mind
Tamron’s new 28-75mm zoom is compatible with many of the advanced features that are specific to mirrorless cameras. This includes:
- Fast Hybrid AF
- Eye AF
- Direct Manual Focus (DMF)
- In-camera lens correction (shading, chromatic aberration, distortion)
- Camera-based lens unit firmware updates
* Features vary by camera. Please consult your camera’s instruction manual for details.
*As of March 2018
Additional features
For greater protection when shooting outdoors, leak-resistant seals throughout the lens barrel help protect your equipment.
The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints.

The application of BBAR (Broad-Band Anti-Reflection) Coating for suppressing reflections on lens element surfaces minimises unwanted flare and ghosting to deliver sharp, crisp, high-contrast images.
