Sigma 28- vs Tamron 70-

Price Comparison

The Sigma 28-70mm F2.8 DG DN for Sony E is priced at $859.95, while the Tamron 70-180mm F/2.8 Di III VC VXD G2 for Sony E-Mount is priced at $999.00. This makes the Sigma lens about 14% cheaper than the Tamron lens. While both lenses are positioned as high-quality options for Sony E-mount cameras, the price difference could influence budget-conscious photographers. The Sigma lens offers a more accessible entry point for those looking to balance quality with cost.

Focal Length and Versatility

The Sigma 28-70mm lens provides a versatile focal range suitable for a variety of shooting conditions, including portraits, landscapes, and street photography. In contrast, the Tamron 70-180mm lens offers a longer focal length, making it ideal for telephoto applications, such as wildlife or sports photography. The broader zoom range of the Tamron lens allows for more creative compositions and greater subject isolation, thanks to its ability to reach up to 180mm. This makes it a more specialized choice for photographers who require that extra reach.

Build Quality and Design

Both the Sigma and Tamron lenses exhibit superb build quality, but their designs cater to different needs. The Sigma 28-70mm features a lightweight and compact body, making it more suited for daily use and portability. In contrast, the Tamron 70-180mm is designed with moisture-resistant construction and a fluorine coating, enhancing its durability in challenging environments. While the Sigma is easy to carry for long periods, the Tamron's robust design appeals to photographers working in variable weather conditions.

Autofocus and Performance

The Sigma lens incorporates a focus mode switch, allowing for quick adjustments between autofocus and manual focus. However, the Tamron lens boasts the VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism, which offers high-speed and high-precision autofocus with improved subject tracking. This can be particularly beneficial for capturing fast-moving subjects in both still photography and video. The advanced autofocus system of the Tamron lens may provide an edge for action photographers needing reliable performance.

Image Stabilization

The Tamron 70-180mm comes equipped with TAMRON's proprietary VC (Vibration Compensation) image stabilization, a feature that can significantly reduce camera shake during handheld shooting, especially at longer focal lengths. The Sigma 28-70mm does not explicitly mention image stabilization in its features, which might put it at a disadvantage for low-light shooting or when using slower shutter speeds. The presence of stabilization in the Tamron lens makes it a more appealing choice for photographers who frequently work in challenging lighting conditions.

Specialty Features

The Sigma lens features a nano porous coating that enhances optical performance, helping to reduce flare and ghosting, while also improving contrast in backlit situations. On the other hand, the Tamron lens offers a unique minimum object distance (MOD) of 0.3m (11.8 inches) at 70mm, allowing for close-up photography. This could be particularly advantageous for photographers who wish to explore macro-style shots without switching lenses. Each lens brings distinct features that cater to different photographic styles and needs.

User Experience and Customization

The Tamron 70-180mm lens supports the dedicated TAMRON Lens Utility and TAMRON Lens Utility Mobile apps, allowing users to customize functions based on their shooting preferences. This level of customization is not mentioned for the Sigma lens, which may limit personalization for certain photographers. The ability to adapt and fine-tune settings can enhance the shooting experience, making the Tamron lens particularly attractive for tech-savvy users looking for a tailored approach to their photography.

Which should you buy?

Ultimately, the choice between the Sigma 28-70mm F2.8 DG DN and the Tamron 70-180mm F/2.8 Di III VC VXD G2 depends on your specific photography needs. If you're looking for a more budget-friendly, versatile lens for everyday shooting, the Sigma offers excellent performance at a lower price point. However, if you require a longer focal length, advanced autofocus capabilities, and image stabilization for dynamic shooting situations, the Tamron lens justifies its higher price. Consider your shooting style and requirements to make the best choice for your photographic journey.
