Tamron 17-70mm f/2.8 for Sony review

In December 2020, Tamron announced an exciting new lens: the 17-70mm f/2.8 for Sony.

The Tamron 17-70mm is small, lightweight, and designed for APS-C cameras – plus, it offers two excellent features often lacking on Tamron lenses.

But how does it function in the real world? And is it worth the $ 799 price tag?

Let’s find out in this hands-on Tamron 17-70mm for Sony review!

Tamron 17-70mm for Sony: overview

A 24-105mm lens offers one of the most popular focal length ranges available, thanks to its wide-to-telephoto reach. It’s a versatile pick used by casual and professional photographers alike.

And the 17-70mm is Tamron’s version of this lens because its focal length translates to 25.5-105mm on an APS-C body.

The Tamron 17-70mm is made for Sony APS-C (crop-sensor) cameras, so it’s ideal when combined with the popular Sony a6000 (or any of its recent variations). The lens can also be used on Sony full-frame cameras like the Sony a7S III – as long as the APS-C mode is selected.

Constant fast aperture

The 17-70mm f/2.8 for Sony is Tamron’s first fast-aperture zoom lens for APS-C cameras.

The lens maintains a constant f/2.8 aperture throughout the entire zoom range, while other APS-C Tamron zooms use variable apertures (i.e., apertures that shift as you zoom).

A constant aperture, especially a fast f/2.8 aperture, makes the 17-70mm great for shooting in low light. And at f/2.8, you can capture shots with creamy bokeh, like this one here:

Vibration compensation

The 17-70mm also comes with Tamron’s image stabilization (Tamron calls this VC, or Vibration Compensation) to reduce camera shake.

Note that VC is often missing on Tamron lenses, especially those with constant apertures, so it’s certainly a welcome bonus on the 17-70mm.

Lenses with VC make it easier to shoot handheld photos and videos, especially at slow shutter speeds. That’s how I was able to pull off this handheld long exposure:

(Speaking of video: the 17-70 is a great video lens, thanks to the flexible zoom range, constant aperture, and inclusion of VC!)

Build and handling

If you’ve tried any recent Tamron lenses, the 17-70mm will look and feel very similar.

The lens is made mostly of plastic, which helps keep the weight down (it comes in at 1.2 lb/525 g), though you also get rubber zoom and focus rings.

The lens physically extends and retracts when the zoom ring is twisted. With dimensions of 2.9 x 4.7 in (74.6 x 119.3 mm), the lens can feel a bit large and off-balance when attached to a smaller camera like the Sony a6000. It definitely feels more balanced when used with a Sony full-frame camera.

The Tamron 17-70mm f/2.8 for Sony is moisture resistant and also has a front element with a fluorine coating to protect it from smudging.

And speaking of the front element, the lens has a filter size of 67 mm, common among Tamron’s recent lenses.

Performance

I used the Tamron 17-70mm in outdoor hiking and indoor restaurant settings, and the autofocus worked well for photos and videos.

The lens has quiet focusing thanks to an RXD stepping motor. This works wonderfully with Sony mirrorless cameras, which still offer the best autofocus on the market.

It’s easy to switch to full manual focus simply by twisting the focus ring. Also, with a minimum focusing distance of 7.5 in (19 cm), the lens has decent macro capabilities (and close-up shots look great with that gorgeous f/2.8 bokeh).

Image quality

Constant-aperture lenses tend to produce sharp, crisp images. You pay for it, though, because constant-aperture lenses – especially zoom lenses – don’t come cheap.

But while the Tamron 17-70mm is priced well under $ 1000, image quality is tack sharp across the entire focal length range, even at f/2.8. If Tamron can make more lenses like this at similar price points, they’ll win over many photographers and videographers.

At times, the 17-70mm does produce chromatic aberration and excessive vignetting, especially when shooting scenes with high contrast. Luckily, these are problems that can easily be solved in most photo editing programs, including Lightroom or Photoshop.

Tamron 17-70mm alternatives

There are no true competitors to the Tamron 17-70mm f/2.8, at least not at its price point. When looking at similar lenses, the price goes up dramatically – or you sacrifice certain features.

Sony lens choices

The closest Sony competitor is the Sony E 16-55mm f/2.8 (24-82.5mm on APS-C cameras), which offers the constant f/2.8 aperture but is 15mm short on the telephoto side. The 16-55 also lacks image stabilization and will set you back $ 1,300.

The Sony E 18-105mm f/4 is a more affordable choice, coming in at around $ 600. This APS-C zoom lens offers a wider focal range than the Tamron plus image stabilization. However, the constant aperture is f/4, which is a lot slower than the Tamron’s f/2.8.

Who should buy the Tamron 17-70mm for Sony?

Considering the price and features of this lens, the Tamron 17-70mm is suitable for both professional photographers and videomakers alike, especially for those on a budget.

The lens’s features are typically found on glass that costs twice as much, including the constant f/2.8 aperture and the Vibration Compensation. It also offers remarkably sharp image quality considering its cost.

And given the relatively accessible price, the Tamron 17-70mm is also appropriate for beginner or amateur photographers and videomakers looking to increase their skills.

Using a constant f/2.8 aperture is a treat, and this lens will help budding photographers take better images in low light with nice, creamy bokeh.

So grab the Tamron 17-70mm f/2.8 for Sony right here!

The 17-70mm F2.8 Di III-A VC RXD will be available in mid-January for $ 799.

Press release

Tamron Announces World’s First[1] 17-70mm F2.8 Wide Range 4.1x Standard Zoom Lens with VC For APS-C Mirrorless Cameras

17-70mm F/2.8 Di III-A[2] VC RXD (Model B070)

December 2, 2020, Commack, NY – Tamron announces the launch of the 17-70mm F/2.8 Di III-A VC RXD (Model B070), a high-speed standard zoom lens for Sony E-mount APS-C mirrorless cameras on January 14, 2021 at approximately $ 799. Due to the current global health crisis, the release date or product supply schedule could change.

The new 17-70mm F2.8 is Tamron’s first high-speed zoom lens for mirrorless cameras with APS-C size sensors. It features a maximum aperture of F2.8 across the entire 4.1x zoom ratio covering a focal length of 17-70mm (a full-frame equivalent of 25.5-105mm) ideal for everyday use, and superb optical performance. It is a small, lightweight lens that is also equipped with Tamron’s VC (Vibration Compensation) mechanism to minimize camera shake. This VC mechanism leverages AI technology when shooting video.

The lens features Moisture-Resistant Construction, Fluorine Coating and a Ø67mm filter size – the same as the Tamron series of lenses for full-frame mirrorless cameras. Compatible with many of the features that Sony builds into its cameras, including Fast Hybrid AF and Eye AF, the lens is the ideal everyday zoom for a multitude of situations. It is a highly practical lens that enables photographers to attain high image quality while enjoying the benefits of the large F2.8 aperture.

PRODUCT HIGHLIGHTS

World’s first high-speed standard zoom lens for APS-C cameras with the focal length range of 17-70mm 4.1x zoom ratio

The Model B070 has a focal length range of 17-70mm, equivalent to 25.5-105mm on full-frame cameras. It is the first F2.8 high-speed zoom lens in the world for APS-C mirrorless cameras to achieve a 4.1x zoom ratio.

Outstanding optical performance

The optical construction of the new 17-70mm F2.8 features 16 elements in 12 groups. Two GM (Glass Molded Aspherical) lens elements and one hybrid aspherical lens element are precisely arranged to maintain high-resolution performance from edge to edge.

Upgraded VC effective in combination with Sony APS-C mirrorless cameras, leveraging AI for video shooting

The 17-70mm F2.8 features Tamron’s proprietary VC mechanism. Additional sophisticated algorithms optimized for this model and a dedicated, independently operating MPU all combine to superbly compensate for vibration. This feature is available when the lens is used with cameras with or without in-body image stabilization. When shooting video, by leveraging AI technology, image stabilization performance improves compared to conventional models.

Close focusing?MOD is just 7.5” at the wide-angle end

The 17-70mm F2.8 zoom focuses close, down to 7.5” MOD (Minimum Object Distance). This is far superior to the performance achieved by conventional high-speed zoom lenses for APS-C cameras. In addition, the 15.4” MOD at the 70mm telephoto end ensures good close-range shooting performance allowing photographers to enjoy compelling close-up shots.

A highly portable compact design

The 17-70mm F2.8 zoom measures a scant 4.7” in length and 74.6mm in maximum diameter and weighs only 18.5 oz. The lens also maintains the same small Ø67mm filter size of each lens in the Tamron mirrorless lens line-up. This is remarkable for a lens with built-in VC image stabilization. When used with Sony’s APS-C mirrorless cameras, this zoom is nicely balanced and provides a comfortable user experience.

Just posted: Our review of the Sigma 17-70mm f/2.8-4 DC Macro OS HSM | C. This lens occupies its own little niche in the market, as an upgrade to the typical 18-55mm zoom that offers both usefully extended zoom range and a faster maximum aperture. It also includes Sigma’s ‘Hypersonic Motor’ for silent focusing, and built-in Optical Stabilisation. In the latest of our lens reviews prepared in partnership with DxOMark, we see whether it should be top of the short-list for SLR owners looking to progress beyond their kit lens.
