TAMRON 17-50mm F4 A068: World’s First Ultra-Wide to Standard Zoom
TAMRON announces the development of the 17-50mm F/4 Di III VXD (Model A068) for Sony E-mount full-frame mirrorless cameras. The innovative zoom lens covers an unusually broad range from 17mm ultra-wide-angle to 50mm standard, making it the world’s first zoom lens for full-frame mirrorless cameras to offer this particular focal-length range.
With a constant F4 aperture throughout the zoom range, the lens is designed for both still photography and video. Its combination of ultra-wide coverage, standard focal lengths, compact construction and high-speed autofocus makes the A068 a versatile option for photographers and content creators who want to cover multiple shooting situations with a single lens.
TAMRON announced the development of the lens on August 24, 2023, with the launch later scheduled for October 19, 2023.
The World’s First 17-50mm Full-Frame Zoom
The defining feature of the TAMRON 17-50mm F4 A068 is its unique focal-length range.
Most wide-angle zooms stop before reaching the standard focal-length range, while standard zooms typically do not extend as far into the ultra-wide range. The A068 bridges these two categories by covering 17mm through 50mm in a single lens.
At 17mm, the lens provides an ultra-wide perspective suited to landscapes, architecture, interiors and expansive scenes. At 50mm, the field of view approaches the natural perspective associated with standard photography, making it useful for everyday subjects and portraits.
This combination reduces the need to change lenses when moving between wide environmental compositions and more natural-looking standard focal lengths.
Constant F4 Aperture Across the Zoom Range
The A068 maintains a constant F4 maximum aperture from 17mm through 50mm.
A constant aperture means photographers and videographers can zoom without changing the maximum available aperture. This is particularly useful for video because exposure can remain consistent while changing focal length.
The F4 aperture also provides a balance between brightness, portability and lens size, helping the A068 remain compact while covering an unusually broad range.
One Lens for Wide-Angle and Standard Photography
The 17-50mm F4 full-frame zoom is designed as an everyday lens that can handle a wide range of subjects.
Landscapes
The 17mm ultra-wide end allows photographers to capture expansive landscapes and emphasize the scale of a scene.
Architecture and Interiors
The wide field of view is useful when photographing buildings, interiors and other subjects where space is limited.
Travel Photography
The 17-50mm range provides flexibility for travel photographers who may need both wide compositions and more natural standard perspectives without carrying multiple lenses.
Everyday Photography
At 35mm and 50mm, the lens can be used for snapshots, street photography and everyday subjects.
Portraits
The 50mm end provides a more natural perspective for environmental portraits and casual people photography.
Compact Design with Internal Zoom
Despite its unusual focal-length range, the A068 is designed to remain compact and easy to handle.
The lens measures approximately 114.4mm in length and weighs 460g. Its internal zoom mechanism keeps the physical length of the lens constant while zooming.
The fixed barrel length also helps maintain a consistent center of gravity as the focal length changes.
This is particularly beneficial for video creators using a gimbal or other camera support because the lens does not physically extend as it zooms.
High-Speed VXD Autofocus
The TAMRON 17-50mm F4 A068 uses TAMRON’s VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism.
VXD provides high-speed and high-precision autofocus while maintaining quiet operation. The system is designed to accurately track moving subjects and is suitable for both still photography and video.
The focus mechanism can make the lens useful for subjects such as children, pets and other unpredictable moving subjects.
Its quiet operation is also beneficial when recording video in environments where autofocus noise could become distracting.
Close-Focusing Capability from 17mm
The A068 also offers strong close-range performance for a wide-angle zoom.
At the 17mm end, the lens can focus as close as 0.19m, with a maximum magnification ratio of 1:4.6. At 50mm, the minimum object distance is 0.3m, with a maximum magnification ratio of 1:3.8.
This allows photographers to move close to subjects and create compositions with exaggerated perspective, environmental context and foreground emphasis.
The close-focusing capability is particularly useful for travel, food, lifestyle and creative photography.
High Optical Performance Across the Zoom Range
The lens uses an optical construction of 15 elements in 13 groups.
Its optical design incorporates three LD (Low Dispersion), one GM (Glass Molded Aspherical) and two hybrid aspherical lens elements to help control aberrations and maintain image quality across the zoom range.
TAMRON also uses its BBAR-G2 coating to help suppress ghosting and flare, supporting clear and high-contrast images when shooting in challenging lighting conditions.
The result is a compact lens designed to provide consistent image quality from the ultra-wide 17mm end through the standard 50mm range.
A Versatile Lens for Video Creators
The TAMRON 17-50mm F4 Sony E lens is designed with video shooting in mind.
The combination of a constant F4 aperture, internal zoom mechanism and quiet VXD autofocus makes the lens suitable for a variety of video applications.
Because the lens does not change physical length during zooming, its balance remains more consistent when mounted on a gimbal or video rig.
The 17mm starting point is also useful for establishing shots and confined spaces, while 50mm provides a tighter perspective for subjects and details.
TAMRON Lens Utility Compatibility
The A068 is compatible with TAMRON Lens Utility, TAMRON’s software application for customizing supported lens functions.
The software can be used with compatible smartphones or computers to expand the possibilities of lens operation for still photography and video production.
This adds further flexibility for creators who want to configure supported lens functions according to their shooting workflow.
Designed for Outdoor Photography
The A068 features Moisture-Resistant Construction and Fluorine Coating for additional convenience when shooting outdoors.
The Fluorine Coating helps make the front and rear lens surfaces more resistant to water and oil, while also making them easier to clean.
Combined with its compact 460g design, the lens is well suited to travel, hiking, camping and other outdoor activities.
67mm Filter Size
The lens uses a 67mm filter diameter, a common size across TAMRON’s lineup of compact mirrorless lenses.
Photographers who use multiple TAMRON lenses with 67mm filters can share compatible filters and accessories between lenses.
This can reduce the number of filters and lens accessories that need to be carried when traveling.

A Unique Alternative to Traditional Standard Zooms
The TAMRON 17-50mm F4 A068 takes a different approach to the conventional full-frame zoom.
Rather than starting around 24mm or 28mm, the lens begins at 17mm, providing a significantly wider perspective before extending to 50mm. This allows photographers to move from expansive ultra-wide compositions to a natural standard perspective without changing lenses.
Its constant F4 aperture, internal zoom design, VXD autofocus, close-focusing capability and compact 460g body further increase its versatility.
The World’s First 17-50mm Full-Frame Zoom
The TAMRON 17-50mm F4 A068 introduced a unique combination of focal lengths to the full-frame mirrorless market.
By covering 17mm ultra-wide through 50mm standard, the lens gives photographers a broader range of creative possibilities in a single compact package. Its constant F4 aperture and internal zoom design also make it particularly well suited to hybrid photography and video.
For Sony E-mount full-frame photographers looking for a compact lens that can cover landscapes, travel, everyday photography and video without frequent lens changes, the A068 offers a distinctive all-in-one solution.
