Tamron, the renowned maker of high-quality lenses, has come up with the world’s first high-speed standard zoom lens for APS-C cameras, called the Tamron 17-70mm f/2.8 Di III-A VC RXD Lens for Sony E APS-C Mirrorless Cameras. This lens is a game-changer for photographers who shoot on APS-C cameras as it has a focal length range from 17-70mm, giving you a 4.1x zoom ratio. In this review, we will delve into the features, pros, and cons of this lens, which has become increasingly popular among photographers.


The Tamron 17-70mm f/2.8 Di III-A VC RXD Lens is designed to cater specifically to Sony E APS-C mirrorless cameras, with a 4.1x zoom ratio. Compared to other lenses available in the market, this lens has a wide-angle focal length of 17mm, making it ideal for landscape photography.

The lens has been made using high-quality materials, which not only make it sturdy but also adds to the durability of the lens. The lens features 16 elements in 12 groups, which makes it unmatched when it comes to optical performance.

One of the unique features of the Tamron 17-70mm f/2.8 Di III-A VC RXD Lens is the two GM (Glass Molded Aspherical) lens -elements and one hybrid aspherical lens element that it features, which helps deliver unsurpassed image quality. Additional features such as the upgraded VC have made shooting videos with this lens a breeze, thanks to the AI (Artificial Intelligence) system, which has improved its effectiveness.

With a reduced minimum object distance (MOD) of just 7.5 inches at 17mm and 15.4 inches at 70mm, the Tamron 17-70mm f/2.8 Di III-A VC RXD Lens allows you to get up close to your subject, making it easily possible to isolate a subject from the background.


The first thing that stands out with the Tamron 17-70mm f/2.8 Di III-A VC RXD Lens is its focal length range, which is perfect for landscape photography, portrait photography, and street photography. With a maximum aperture of f/2.8, this lens allows for excellent bokeh, which can be used to draw attention selectively to your subject.

Thanks to the advanced vibration compensation (VC) technology, this lens offers an impressive enlargement ratio of 4.1x, making it significantly more superior to other lens options available on the market. With this feature, you can maintain image stabilization while capturing high-quality photos and videos.

Its moisture-resistant construction and fluorine coating further offer robust protection to the lens, making it ideal for capturing photos in different weather conditions. The lens is specifically designed to cater to Sony E APS-C mirrorless cameras, which makes it a perfect fit for those who own these camera models.


Although the Tamron 17-70mm f/2.8 Di III-A VC RXD is an excellent lens, it is also a bit heavy, weighing in at 525 grams. This can be an issue for photographers who need to be out and about for long hours shooting.

Another concern is that the lens is relatively expensive when compared to other lenses available on the market. The high price might turn out to be a deal-breaker for aspiring photographers who are still trying to establish themselves in the field.

Moreover, the lens was developed for Sony E APS-C mirrorless cameras, so it may not be suitable for use on other camera brands such as Canon or Nikon. That being said, the lens works flawlessly on Sony cameras, giving users optimal performance.


The Tamron 17-70mm f/2.8 Di III-A VC RXD Lens is an excellent product that embodies the high-quality standards that Tamron has set for itself. With excellent optics and advanced features, the lens offers a compelling value proposition to photographers looking for something unique.

While the Tamron 17-70mm f/2.8 Di III-A VC RXD Lens might be a bit heavy and pricier than other lenses out there, it more than compensates for its weight with its remarkable optical quality and weather-resistant construction. Overall, this lens is a reliable, high-performing tool that every serious photographer should consider to add to their arsenal. If you are someone who wants to capture stunning photos and videos, then the Tamron 17-70mm f/2.8 Di III-A VC RXD Lens is an excellent investment.
