TAMRON G2 Trinity: 16-30mm, 28-75mm and 70-180mm F2.8

What Is the TAMRON G2 Trinity?

The TAMRON G2 Trinity is a three-lens F2.8 zoom system consisting of:

• 16-30mm F/2.8 Di III VXD G2 (A064) — ultra wide-angle zoom
• 28-75mm F/2.8 Di III VXD G2 (A063) — standard zoom
• 70-180mm F/2.8 Di III VC VXD G2 (A065) — telephoto zoom

Together, the lenses cover focal lengths from 16mm to 180mm while maintaining a constant F2.8 maximum aperture throughout each zoom range.

This combination gives photographers access to ultra wide-angle, standard and telephoto perspectives without having to compromise on aperture speed.

The G2 Trinity Covers 16mm to 180mm

The strength of the TAMRON F2.8 G2 Trinity is the broad range covered by the three lenses.

The 16-30mm F2.8 G2 provides ultra wide-angle coverage for landscapes, architecture, interiors, astrophotography and creative compositions.

The 28-75mm F2.8 G2 covers the standard zoom range and is suited to everyday photography, portraits, events and travel.

The 70-180mm F2.8 G2 provides telephoto reach for portraits, sports, events and other subjects that benefit from greater subject isolation.

Together, these three lenses create a continuous system from 16mm through 180mm.

16-30mm F2.8 G2: The Ultra Wide-Angle Zoom

The final addition to the Trinity is the 16-30mm F/2.8 Di III VXD G2 (Model A064).

Designed as the successor to the 17-28mm F/2.8 Di III RXD (A046), the second-generation lens expands the wide end from 17mm to 16mm while extending the telephoto end to 30mm.

The lens maintains a compact and lightweight design while introducing updated optics, improved autofocus and enhanced operability.

The 16mm focal length provides a wider field of view for expansive landscapes, architecture, interiors and creative perspectives.

28-75mm F2.8 G2: The Standard Zoom

The 28-75mm F/2.8 Di III VXD G2 (Model A063) serves as the standard zoom in the G2 Trinity.

Its 28-75mm range covers many of the focal lengths commonly used for everyday photography.

At 28mm, photographers can capture wider scenes, while 50mm and 75mm provide more natural perspectives for portraits and everyday subjects.

The constant F2.8 aperture makes the lens versatile in changing lighting conditions and provides greater control over depth of field.

The A063 uses TAMRON’s VXD autofocus system and is designed to provide high-speed, high-precision focusing for both photography and video.

70-180mm F2.8 G2: The Telephoto Zoom

Completing the telephoto portion of the system is the 70-180mm F/2.8 Di III VC VXD G2 (Model A065).

The lens combines a constant F2.8 aperture with a compact telephoto design and VXD autofocus.

The second-generation model also incorporates VC (Vibration Compensation), providing additional support when shooting handheld at longer focal lengths.

The 70-180mm range is particularly useful for portraits, sports, events and outdoor photography where additional reach and subject separation are important.

One Constant F2.8 Aperture System

One of the biggest advantages of the TAMRON G2 Trinity lenses is the constant F2.8 aperture.

Each lens maintains F2.8 throughout its respective zoom range:

• 16-30mm — F2.8
• 28-75mm — F2.8
• 70-180mm — F2.8

This consistency makes the three-lens system particularly useful for photographers who frequently switch lenses during a shoot.

Exposure settings can remain more consistent when moving between lenses, while the F2.8 aperture provides flexibility for low-light shooting and shallow depth-of-field effects.

Designed as a Complete Lens System

The G2 Trinity was designed not simply as three individual lenses, but as a coordinated system.

The lenses share a consistent approach to:

• Fast F2.8 apertures
• Compact mirrorless designs
• High-speed autofocus
• Moisture-resistant construction
• Fluorine coating
• TAMRON Lens Utility compatibility
• A unified 67mm filter size

The common 67mm filter size is especially convenient for photographers using the complete system because filters can be shared between the three lenses.

From Ultra Wide-Angle to Telephoto

The 16-180mm coverage allows the G2 Trinity to handle a broad variety of photographic situations.

Landscapes

The 16-30mm lens provides the expansive perspective needed to capture large landscapes and dramatic foregrounds.

Architecture and Interiors

The ultra wide-angle range is useful for photographing buildings and interiors where working space is limited.

Travel Photography

The 28-75mm lens provides a flexible standard range for everyday travel photography, while the 16-30mm and 70-180mm lenses extend the system for specialized subjects.

Portraits

The 28-75mm and 70-180mm lenses provide useful focal lengths for portraits, with the F2.8 aperture helping create subject separation.

Sports and Events

The 70-180mm F2.8 G2 provides telephoto reach while maintaining a fast aperture and VXD autofocus.

Video and Content Creation

The three lenses are also designed with video creators in mind, offering fast autofocus and compatibility with TAMRON Lens Utility for supported customization features.

Compact and Lightweight G2 Designs

A key characteristic of the TAMRON G2 Trinity is the effort to balance performance with portability.

The lenses are designed for full-frame mirrorless cameras while maintaining compact dimensions that make them practical for travel and everyday use.

The 16-30mm F2.8 G2, for example, continues the compact philosophy of its 17-28mm predecessor while expanding the focal-length range and updating the optical and autofocus systems.

This makes the system attractive to photographers who want professional-level F2.8 performance without carrying oversized zoom lenses.

High-Performance Autofocus

The G2 Trinity also benefits from TAMRON’s autofocus technologies.

The 16-30mm F2.8 G2 and 28-75mm F2.8 G2 use VXD linear motor focus mechanisms, while the 70-180mm F2.8 G2 also uses VXD together with VC stabilization.

VXD is designed to provide fast and precise autofocus while maintaining quiet operation, making it suitable for both still photography and video.

TAMRON Lens Utility Compatibility

The G2 lenses are compatible with TAMRON Lens Utility, allowing photographers and videographers to customize supported lens functions.

The software can be used to configure practical functions for different shooting workflows, providing additional control when using the lenses for photography or video production.

This compatibility helps make the G2 Trinity useful not only for still photographers but also for hybrid shooters and content creators.

A Unified 67mm Filter System

All three lenses use a 67mm filter size, creating a convenient accessory system for photographers who own the complete Trinity.

Instead of carrying different filter sizes for each lens, users can share compatible 67mm filters between the lenses.

This is particularly useful for travel photographers who want to keep their camera bag as compact as possible.

The TAMRON G2 Trinity for Full-Frame Mirrorless Cameras

The three lenses are designed for full-frame mirrorless camera systems.

The 16-30mm F2.8 G2 and 28-75mm F2.8 G2 are available for Sony E-mount and Nikon Z mount systems, while the 70-180mm F2.8 G2 is available in Sony E-mount and, subsequently, Nikon Z mount. Availability varies by mount and release date.

With the introduction of the A064, TAMRON completed its fast F2.8 G2 lens lineup for full-frame mirrorless photographers.

TAMRON G2 Trinity Specifications

Together, the three lenses provide 16-180mm coverage at a constant F2.8 maximum aperture across the system.

What Is “Daisangen”?

TAMRON uses the term “Daisangen” to describe its three-lens F2.8 zoom combination.

The term originates from mahjong, where Daisangen refers to a winning hand made by collecting three sets of dragon tiles. In photography, the term has been adopted in Japan to describe a set of three zoom lenses consisting of wide-angle, standard and telephoto lenses, each with a constant F2.8 aperture.

The TAMRON G2 Trinity follows this concept with its 16-30mm, 28-75mm and 70-180mm F2.8 zooms.

Why Choose the TAMRON G2 Trinity?

The biggest advantage of the system is flexibility.

Instead of relying on one lens for every situation, photographers can choose the appropriate focal-length range while maintaining a consistent F2.8 aperture.

The system offers:

• 16mm ultra wide-angle coverage
• 28-75mm standard zoom coverage
• 70-180mm telephoto coverage
• Constant F2.8 aperture
• VXD autofocus
• Compact mirrorless-friendly designs
• 67mm shared filter size
• TAMRON Lens Utility compatibility

This combination makes the G2 Trinity suitable for photographers who want a complete full-frame zoom system for everything from expansive landscapes to compressed telephoto compositions.
