Optical Performance Comparison

The Tamron 17-70mm lens stands out with its exceptional optical performance, thanks to its advanced design featuring two Glass Molded Aspherical (GM) lens elements and one hybrid aspherical lens element. This configuration helps achieve sharp images with minimal distortion across the zoom range. On the other hand, the Tamron 28-200mm lens uses a special arrangement of lens elements to provide high-quality rendering throughout its extensive zoom range. Both lenses demonstrate impressive optical capabilities, but the 17-70mm lens may offer superior performance for those focused on sharpness and detail, especially at its maximum aperture of f/2.8.

Zoom Range and Versatility

The Tamron 17-70mm lens provides a focal length range of 17-70mm equivalent to 25.5-105mm in full-frame terms, making it highly versatile for a range of photography styles. It excels in everyday shooting, allowing users to capture everything from tight portraits to expansive landscapes. In contrast, the Tamron 28-200mm lens covers a much broader zoom range of 28-200mm, allowing for greater flexibility in capturing distant subjects and wide-angle scenes alike. This makes the 28-200mm lens an excellent choice for travel and outdoor photography, where the ability to quickly switch between wide-angle and telephoto shots can be beneficial.

Low-Light Performance

Both lenses feature impressive maximum apertures that enhance their low-light performance. The Tamron 17-70mm maintains a consistent f/2.8 aperture across its entire zoom range, providing excellent light-gathering capabilities, ideal for indoor shooting or low-light conditions. Conversely, the Tamron 28-200mm lens offers a maximum aperture of f/2.8 at 28mm, which gradually narrows to f/5.6 at 200mm. While it still performs well in lower light, the 17-70mm lens is likely to provide better results in challenging lighting situations due to its constant aperture.

Build Quality and Durability

Both lenses are constructed with a focus on durability and usability, featuring moisture-resistant designs and fluorine coatings that protect against dust and moisture. This makes them suitable for outdoor use in various weather conditions. The Tamron 17-70mm lens is designed specifically for APS-C cameras, while the Tamron 28-200mm lens caters to both full-frame and APS-C models. The lightweight design of the 28-200mm lens, at just 20.3 oz, enhances its portability, which is essential for photographers on the go.

Price Comparison

The Tamron 17-70mm lens is priced at $599.00, which is about 17% cheaper than the Tamron 28-200mm lens, priced at $699.00. This price difference may influence budget-conscious photographers who are looking for a high-quality lens without breaking the bank. However, the additional cost of the 28-200mm lens may be justified for those who value its extensive zoom range and versatility for various shooting scenarios.

Which should you buy?

Choosing between the Tamron 17-70mm f/2.8 Di III-A VC RXD Lens and the Tamron 28-200 F/2.8-5.6 Di III RXD ultimately depends on your specific needs as a photographer.
