The Sony lens is engineered for super-telephoto shooting, while the Tamron offers versatility for a range of shooting scenarios. Understanding the core differences will help you make an informed choice.

If you're looking for a telephoto lens for wildlife or sports photography, the Sony might justify its price tag with its extended focal length. However, for general photography and everyday use, the Tamron's price could represent better value.
Focal Length and Versatility
A standout feature of the Sony FE 400-800mm is its impressive focal length range of 400 to 800mm, making it ideal for capturing distant subjects with clarity and detail. In contrast, the Tamron 28-75mm focuses on a more versatile range suitable for various photography styles, including portraiture and landscapes. This gives the Tamron an edge for photographers who need a reliable all-rounder lens for everyday situations.
Autofocus Performance
Both lenses offer advanced autofocus capabilities, but they cater to different needs. The Sony FE 400-800mm boasts fast and precise autofocus that can capture fast-moving subjects, making it suitable for wildlife and sports photography. The Tamron 28-75mm features a VXD linear motor, which provides fast, quiet, and high-precision autofocus, ideal for both stills and video. The choice here depends on whether you prioritize quick focus on distant subjects or versatility in various photography environments.
Weight and Portability
Weight and size are crucial factors for photographers on the go. The Tamron 28-75mm weighs just 19.4 ounces and measures 4.7 inches long, making it easy to carry and handle for extended shooting sessions. Conversely, while the Sony FE 400-800mm provides exceptional reach, it is inherently bulkier and heavier, which could become cumbersome during long shoots. If portability is a top priority, the Tamron is a more practical choice.
Build Quality and Durability
In terms of build quality, both lenses are designed with durability in mind. The Tamron 28-75mm features moisture-resistant construction, making it suitable for outdoor use despite unpredictable weather conditions. The Sony FE 400-800mm, while not explicitly detailed in its moisture resistance, is built for professional use and includes high-performance teleconverters that extend its capabilities. Depending on your shooting environment, this could influence your choice.
Specialized Features
The Sony FE 400-800mm includes features like internal zoom for stable handling and compatibility with high-performance teleconverters, which enhance its utility for serious wildlife and sports photographers. The Tamron 28-75mm excels in close-up photography with a minimum object distance of 7.1 inches, offering creative possibilities for portrait and product photography. If specialized features are essential to your photography style, consider what each lens uniquely offers.
Which should you buy?
Ultimately, the choice between the Sony FE 400-800mm f/6.3-8 G OSS and the Tamron 28-75mm F/2.8 Di III VXD G2 boils down to your specific photographic needs and budget. If you require a super-telephoto lens for distant subjects and are willing to invest significantly, the Sony lens is an excellent option. However, for everyday versatility and a more approachable price point, the Tamron lens stands out as a smart choice for casual and professional photographers alike.
