Development began in 1989, about three years before the release. The development team was tasked with a clear mission; creating a convenient “high-magnification” zoom lens , a wide 28mm to 200mm telephoto in a small compact body that everyone can easily carry around, the All-In-One Zoom Lens.

While similar zoom lens existed, they were bulky, heavy and the image quality was not at expectations, it was not an easy lens to use. The team set a goal for the lens size of cigarette box, making a model using a cylindrical paper model at such size. The start of the ambitious development project.

The development of a "convenient All-in-one zoom" proved to be extremely challenging. With each prototype, resolution tests were repeated over and over. After many trials and errors, leveraging the expertise gained from designing and manufacturing high-power zoom lenses for video cameras and the successful mass production of hybrid aspherical lenses, a breakthrough was finally accomplished.

Model 71D was infused with TAMRON's unique technologies. The optimal arrangement of hybrid aspherical lenses effectively corrected aberrations, while the new function like the Triple Cam Zoom mechanism and use of lightweight engineering plastics were adopted. With additional enhancements to production precision, the lens was finally completed.

Model 71D received enthusiastic support in the European and American markets, later becoming a major hit in Japan as well. However, the development team was not satisfied. The lens had a limitation of a minimum object distance of 2.1m throughout the zoom range, which was acceptable for a 200mm telephoto lens but inadequate for a wide-angle zoom including 28mm. This led to a new challenge for further evolution.

The significant difference with Model 71D was the minimum object distance. While Model 71D had a distance of 2.1m, Model 171D reduced it to 0.52m(20.47in) when using at a focal length of 135mm. The maximum magnification ratio on the film also improved from 1:9.5 to 1:4.8, enhancing the usability of the All-in-one zoom lens.

This was made possible by reevaluating the focus mechanism : switching from the front-focus design of Model 71D, where the large front lens extended forward as the shooting distance decreased, to an internal-focus design in Model 171D, where a small lens inside the barrel moved for focusing without changing the length of the barrel , allowing for closer focusing without compromising image quality. Despite the variation in minimum shooting distance depending on the focal length, the development team was not yet satisfied with this model.

In 2000, Model 371D was introduced, satisfying the development team with its close-up shooting capabilities. With a minimum object distance of 0.49m(19.29in), slightly shorter than before, the lens allowed for shooting at this distance throughout the zoom range, achieving a maximum magnification ratio of 1:4 at 200mm, approaching macro lens specifications.

Although Tamron's All-in-one zoom initially featured only the 28-200mm lens, the demand for longer focal lengths led to the introduction of Model 185D in 1999, extending the telephoto end to 300mm (zoom ratio of 10.7x). While slightly larger than models like 171D, it was well-received by users seeking longer telephoto capabilities. TAMRON continued offering the 28-200mm and 28-300mm lenses until the introduction of digital-specific lenses in 2005.

In 2001, Model A03 achieved unprecedented compactness and lightweight design. The filter size was reduced from 72mm in Model 171D to 62mm. This was made possible by TAMRON's XR (Extra Refractive index) technology, which utilized high-refractive-index glass in the front lens group, correcting aberrations with the rear lens group. This innovative optical design shortened the optical length by placing high-refractive-index lenses in the front group, enabling significant reduction in barrel size for Model A03. This model marked a significant step forward in size, aligning with the ideal of an All-in-one zoom lens that can be taken anywhere and used for any purpose. The external design of the barrel also saw significant changes, leading to the design trend seen in current models. The XR technology was also applied to the 28-300mm series, resulting in the release of Model A06 in 2002.

Around the same time, SLR cameras were undergoing a historic transformation.

Around the year 2000, digital SLR cameras became more affordable, leading to rapid adoption due to their compatibility with computers and printers, as well as cost savings from eliminating film and development costs. However, digital imaging posed challenges such as increased emphasis on lens aberrations, flare, and ghosting compared to film. Internal reflections causing flare became a particular issue, and traditional coatings were often insufficient. Telecentricity (optical systems where light and the optical axis are considered parallel) also became more important.

To address these issues, TAMRON introduced lenses optimized for digital characteristics with specialized optical designs and coatings under the "Di (Digitally integrated) series". In 2004, a full-frame lens Model A061 was released based on the All-in-one zoom Model A06 (for film cameras), but as it is a full-frame lens, when the lens was used on an APS-C camera, the 28mm wide-angle end became equivalent to 42mm*, skewing towards telephoto.

As a result, TAMRON developed All-in-one zoom lenses dedicated to APS-C sensors, unveiling the zoom Model A14 in 2005 with a focal length of 18-200mm, equivalent to 27-300mm* in full-frame terms. This marked the debut of the "Di II series" tailored for APS-C sensors.

In 2006, the 28-200mm Model A03 was also revamped into the digital-compatible Model A031 (Di series).

In 2007, marking 15 years since the release of Model 71D, TAMRON further increased the zoom ratio of Di II All-in-one zoom lenses with the introduction of Model A18, covering a focal length range of 18-250mm. The zoom ratio reached 13.9x, maintaining almost the same barrel size as the previous Model A14 while only slightly increasing weight by about 30g.

Additionally, an All-in-one zoom Model A20 featuring TAMRON's long-developed Vibration Compensation (VC) mechanism was released in the same year.

By this time, image stabilization had become common in standard and telephoto zoom lenses. Model A20, part of the full-frame Di series, offered a focal length of 28-300mm. Equipped with a 4-stop equivalent VC system, the lens provided significant stabilization benefits across the zoom range.

The groundbreaking stability of the VC system, achieved through TAMRON's unique three-coil system, captivated many users as an innovative in-lens stabilization mechanism.

VC was soon integrated into APS-C Di II All-in-one zoom lenses as well. Model B003 was introduced in 2008, featuring VC and extending the focal length to 18-270mm from Model A18. With a remarkable zoom ratio of 15x and the inclusion of image stabilization, photography became more comfortable.

TAMRON had been using DC motors for AF drive in its All-in-one zoom lenses. While cost-effective and responsive, the motors occasionally produced noticeable operational noise.

To address this, TAMRON embarked on developing a new actuator (motor) using piezoelectric elements (=piezos). This actuator, named "PZD (Piezo Drive)," utilized the characteristics of piezo elements to improve the AF drive's quietness and enable compact internal storage within the barrel. The actuator design also contributed to a smaller "VC" implementation, resulting in the release of the APS-C All-in-one zoom Model B008.

Model B008 adopted the stationary wave ultrasonic motor "PZD" and downsized "VC", achieving a compactness close to Model A18. Designed for entry-level digital SLRs, the lens provided a quiet and smooth AF drive, offering an ideal All-in-one zoom experience.

Continuing as the "Pioneer of All-in-one Zooms," TAMRON's pursuit of challenges led to the development of Model B011 in response to the expanding mirrorless camera market around 2010. This lens was designed for APS-C sensors, featuring a compact and lightweight design, high-quality image rendering, an 18-200mm focal length, and enhanced VC for capturing sharp, blur-free photos during everyday shooting and travel.

In April 2014, TAMRON introduced Model B016, enhancing the already high-quality Model B008 to achieve the ideal All-in-one zoom lens of 16-300mm. With a zoom ratio of approximately 18.8x, the lens offered a wide-angle end of 16mm (equivalent to 24mm in full-frame)* and an extended telephoto end up to 300mm (equivalent to 450mm in full-frame)*. Enhanced with a maximum magnification ratio of 1:2.9 for improved macro capabilities, the lens featured a minimum object distance of 0.39m(15.35in). The latest optical design incorporating new materials like UXR and hybrid aspherical lenses enabled size reduction and sharp image quality.

The external design of the barrel was revamped, featuring a premium feel with the use of tungsten silver in the branding. With a wide shooting range, high image quality, and performance, Model B016 was accepted as the "Super All-in-one zoom lens", setting a new standard for the category.

Shortly after, in June 2014, TAMRON released Model A010 for full-frame DSLRs and Model C001 for Micro Four Thirds mirrorless cameras. In August 2015, the successor to the best-selling lens, Model A14, was unveiled as Model B018, featuring VC for improved usability and lighter weight.

In July 2017, Model B028 was introduced, pioneering a new category of "Ultra telephoto All-in-one zoom." Covering a focal length range of 18-400mm (equivalent to 27-600mm in full-frame)* with a zoom ratio of approximately 22.2x, the lens featured a compact and lightweight design with a 3-step retractable barrel, quad cam zoom mechanism, for smooth operation. Equipped with TAMRON's unique HLD (High/Low torque-modulated Drive) motor, the lens achieved high-precision AF drive and power efficiency. Enhanced VC support for "ultra telephoto All-in-one" shooting provided a comfortable photography experience.

TAMRON 's All-in-one zoom lenses evolved to cater to the growing mirrorless camera market around 2020. Model A071, 28-200mm F2.8-5.6 introduced with an F2.8 aperture at the wide end, aimed to pursue fast aperture previously thought unattainable in All-in-one zooms, offering a versatile all-purpose lens. The following year, TAMRON launched 18-300mm, the Model B061, an APS-C mirrorless camera All-in-one zoom featuring the company's fastest and most precise AF, VXD (Voice-coil eXtreme-torque Drive). Extending to 300mm on the telephoto end, the lens catered to APS-C sensors, providing an All-in-one zoom experience with improved usability. In 2024, TAMRON expanded its All-in-one zoom lineup with Model A074, extending the telephoto end to 300mm for full-frame mirrorless cameras. The 28-300mm, with a zoom ratio of 10.7x across the focal range, superior image quality, and a compact size, the lens aimed to push the boundaries of All-in-one zoom lens capabilities.
