Price Comparison
The Sigma 17-40mm F1.8 DC is priced at $919.00, while the Tamron 150-500mm F/5-6.7 is available for $1,199.00, making the Sigma about 17% cheaper than the Tamron. This significant price difference may influence budget-conscious photographers looking for a high-quality lens. The Sigma's lower price point does not compromise its functionality, offering a bright constant aperture that is ideal for various photography styles, including low-light scenarios and creative depth effects.
Optical Performance
When it comes to optical performance, both lenses excel in their respective ranges, but they serve different photographic needs. The Sigma 17-40mm features Art-series optics designed to deliver sharp detail and professional image quality, making it a strong candidate for portraits and travel photography. In contrast, the Tamron 150-500mm boasts remarkable image quality with high resolving power edge-to-edge, making it suitable for wildlife and sports photography where distance is a factor. This difference in focal range highlights how each lens is tailored for specific photography styles.
Build Quality
The Tamron 150-500mm is designed with a compact structure, measuring only 8.4 inches when retracted and 11.3 inches when extended. It also features moisture-resistant construction and a fluorine coating, enhancing its durability in various shooting conditions. The Sigma 17-40mm, while not specified for extreme conditions, is part of Sigma's Art lineup, which typically indicates a high standard of build quality. However, the Tamron's protective features may give it an edge for outdoor photographers who need a rugged lens.
Versatility
In terms of versatility, the Sigma 17-40mm is a bright, constant aperture zoom lens that is well-suited for a variety of shooting situations, from portraits to travel and video. Its wide-angle capabilities make it ideal for capturing expansive landscapes and group shots. On the other hand, the Tamron 150-500mm shines in super-telephoto situations, allowing for spontaneous shooting opportunities that were once limited to tripods. Its long zoom range enables photographers to capture distant subjects with ease, making it the better choice for wildlife or sports photography.
Autofocus and Stabilization
The Tamron 150-500mm features VXD (Voice-coil eXtreme-torque Drive) autofocus technology, which is precise and high-speed, ensuring that photographers can capture fast-moving subjects without missing a beat. Additionally, it includes Tamron's VC (Vibration Compensation) image stabilization mechanism, which is crucial for maintaining sharp images at longer focal lengths. While the Sigma 17-40mm does not specify advanced autofocus technology, its bright aperture allows for faster focusing in low light, making it effective for various shooting conditions, albeit not at the super-telephoto range.
Target User
The Sigma 17-40mm is ideal for photographers who prefer a versatile lens for everyday use, particularly those focusing on portraiture and videography. Its bright aperture and superior optical quality make it a great choice for creative expression. In contrast, the Tamron 150-500mm targets wildlife and sports photographers who need to capture subjects from a distance without compromising on image quality. The choice between the two largely depends on the specific photographic needs and styles of the user.
Image Quality
Both lenses offer exceptional image quality, but they cater to different photographic environments. The Sigma 17-40mm F1.8 is known for its sharpness and clarity across a variety of settings, making it suitable for both portrait and landscape photography. The Tamron 150-500mm, with its BBAR-G2 coating, delivers stunning clarity and contrast, particularly advantageous for telephoto shots. Hence, while both lenses excel in terms of image quality, they do so in different contexts, emphasizing the importance of selecting a lens that aligns with your intended use.
Which should you buy?
Ultimately, the choice between the Sigma 17-40mm F1.8 DC and the Tamron 150-500mm F/5-6.7 hinges on your specific photography needs. If you’re looking for a budget-friendly, versatile lens for general photography, the Sigma is an excellent choice at $919.00. However, if super-telephoto capability and advanced autofocus features are what you seek, the Tamron at $1,199.00 may be worth the investment. Consider your shooting style, budget, and the type of photography you plan to pursue when making your decision.
