Both offer a useful wide-angle to short-telephoto range, fast constant aperture, and stellar image quality for the price. But which one is the better choice for your needs?
Read on as we compare these two leading mid-range zooms to help determine if the Tamron’s extra reach and value or the Sigma’s wider view and tank-like build make it the best fit for your style of shooting. By the end of this guide, you’ll know which of these highly-capable lenses deserves a place in your camera bag.
Introducing the Tamron 28-75mm F/2.8 Di III RXD and Sigma 24-70mm F/2.8 DG DN Art
When it comes to high-quality zoom lenses for Sony full-frame mirrorless cameras, two of the top contenders are the Tamron 28-75mm F/2.8 Di III RXD and the Sigma 24-70mm F/2.8 DG DN Art, Both offer fast f/2.8 constant apertures, weather sealing, and high performance optics. But which one is right for you?
The Tamron 28-75mm is the more compact and lightweight of the two. Weighing just 19.4 ounces, this lens won’t weigh down your Sony a7 III or a9. It’s also more affordable, typically running a few hundred dollars less than the Sigma. The Tamron’s focal range starts at 28mm, which may be wide enough for some shooters. However, if you need to go wider, the Sigma’s 24mm reach could make a big difference.
In terms of image quality, both lenses produce stunning results with sharp details, nice Bokeh, and minimal distortion. The Sigma does have a slight edge, with higher sharpness and contrast. It also has a more durable build, though at 31.5 ounces, it is notably heavier.
For low light and action shots, the fast autofocus and F/2.8 aperture on either lens will serve you well. The Tamron focuses a bit quicker, making it better for moving subjects. But the Sigma’s superior optics may result in slightly better Bokeh and subject isolation.
In the end, you can’t go wrong with either of these lenses. If you want the lightest, most affordable option, the Tamron 28-75mm is hard to beat. But if the highest image quality and most solid build are top priorities, the Sigma 24-70mm Art is worth the splurge. The choice comes down to your needs, preferences and budget.
