Price Comparison

The Sigma 16-300mm F3.5-6.7 DC OS is priced at $694.00, while the Tamron 28-200 F/2.8-5.6 is slightly more expensive at $699.00. This makes the Sigma lens about 0.86% cheaper than the Tamron lens. While the price difference is minimal, it may influence buyers looking for budget-friendly options. Considering that the Tamron has a higher average price over the last 90 days at $766.70, it shows that the current pricing for both lenses is competitive. Buyers might find the Sigma lens appealing if they prefer a lower upfront cost.

Design and Build Quality

Both the Sigma and Tamron lenses boast compact designs, but the Tamron’s lightweight construction may appeal to those prioritizing portability. The Tamron lens weighs 20.3 oz, which is relatively lightweight for a lens, and measures just 4.6 inches in length. This makes it easy to carry and handle during long shooting sessions. The Sigma lens does not specify its weight or dimensions, but it is known for its quality build in the Contemporary line. While both lenses are designed for durability, the Tamron’s moisture-resistant construction and fluorine coating enhance its outdoor usability.

Aperture and Low Light Performance

The Tamron lens offers a fast maximum aperture of F2.8 at the 28mm wide-angle end, which significantly improves its low-light performance compared to the Sigma lens. The Sigma features a variable aperture of F3.5-6.7, which means it may struggle more in dim conditions. This difference is crucial for photographers who plan to shoot in low-light environments, as the faster aperture of the Tamron allows for better light capture and shallower depth of field, providing more creative control over their images.

Zoom Range and Versatility

The Sigma lens has a versatile zoom range of 16-300mm, making it suitable for a wide variety of photography styles, from landscapes to wildlife. In contrast, the Tamron lens offers a zoom range of 28-200mm, which, while still versatile, is more limited on the wide-angle end. However, the Tamron's fast aperture throughout its range provides it with an edge in versatility for low-light shooting. Depending on the user's needs, the Sigma may be preferred for its broader zoom range, while the Tamron excels in low-light conditions and overall image quality.

Image Quality

Image quality is a significant factor when choosing a lens, and both brands are known for their optical performance. The Tamron lens is designed specifically for high-resolution digital cameras, featuring a special arrangement of lens elements that enhance image rendering throughout the zoom range. This attention to optical performance means that users can expect superior image quality from the Tamron. While the Sigma lens is also designed for quality, it does not specify any particular advancements in optical design, making the Tamron potentially the better choice for photographers focused on image quality.

Autofocus Performance

The Tamron lens features an RXD stepping motor unit, which is noted for its exceptionally quiet autofocus performance. This can be particularly beneficial for videographers or those shooting in quiet environments. The Sigma lens does not provide specific information about its autofocus system, making it difficult to directly compare their performance. If autofocus speed and noise levels are critical to your photography or videography, the Tamron may be the more reliable option based on its stated capabilities.

Close-Up Shooting Ability

For photographers interested in close-up work, the Tamron lens shines with its superior up-close shooting performance. It boasts a close focusing distance of 7.5 inches with a 1:3.1 magnification ratio at the wide end, and 31.5 inches with a 1:3.8 ratio at the telephoto end. In comparison, the Sigma lens does not provide specific details about close-up capabilities, which may limit its appeal for macro photography enthusiasts. The Tamron's focus on close-up shooting expands its versatility for creative photography.

Which should you buy?

Choosing between the Sigma 16-300mm F3.5-6.7 DC OS and the Tamron 28-200 F/2.8-5.6 ultimately depends on your specific needs as a photographer. If you prioritize a broader zoom range and a slightly lower price, the Sigma lens may be the better option. However, if you are looking for superior low-light performance, quieter autofocus, and exceptional image quality, the Tamron lens stands out as a strong contender. Consider your shooting style and requirements carefully to make the best decision for your photography needs.
