Sony SEL2470GM E-Mount Camera Lens: FE 24- vs Tamron 17-

Price Comparison

The Sony SEL2470GM is priced at $1,798.00, making it significantly more expensive than the Tamron 17-70mm, which retails for $599.00. This places the Tamron lens about 67% cheaper than the Sony option. The price difference reflects the Sony lens's status as a premium model designed for full-frame cameras, while the Tamron lens caters to users of APS-C mirrorless cameras. This substantial price gap may influence a buyer's decision, particularly those who are budget-conscious or new to photography.

Optical Performance

In terms of optical performance, the Sony SEL2470GM offers superior capabilities with advanced glass elements, including two aspherical elements and an extreme aspherical (XA) element that maximize resolution and minimize aberration. The lens is crafted for breathtaking texture and detail, especially in portrait and event photography. On the other hand, the Tamron 17-70mm features 16 elements in 12 groups, including two GM elements, ensuring outstanding optical quality. While both lenses provide excellent image quality, the Sony lens may edge out in terms of professional-grade performance due to its specialized features.

Focal Length and Versatility

The Sony SEL2470GM boasts a focal length of 24-70mm, which is ideal for various shooting scenarios, from portraits to landscapes. This range is equivalent to 36-105mm on APS-C cameras, making it versatile for full-frame users. Conversely, the Tamron 17-70mm offers a wider focal range of 17-70mm, translating to a full-frame equivalent of 25.5-105mm. This wider angle at the lower end gives the Tamron an advantage for capturing more expansive scenes, making it particularly useful for landscape and architecture photography.

Aperture and Bokeh

When it comes to aperture, the Sony lens features a constant maximum aperture of f/2.8, which provides excellent low-light performance and allows for beautiful bokeh thanks to its 9-blade circular aperture. This aspect makes it an excellent choice for portrait photography where depth of field is crucial. The Tamron lens also maintains a constant f/2.8 aperture throughout its zoom range, which is beneficial for shooting in varying light conditions. However, it has a slightly different design with its optical elements and stabilization features, which may affect the final bokeh quality compared to the Sony lens.

Build Quality and Design

The Sony SEL2470GM is designed with a focus on durability, featuring a dust and moisture-resistant construction, making it suitable for challenging shooting environments. This lens is also equipped with a Direct Drive Super Sonic wave Motor (DDSSM), ensuring fast and quiet autofocus performance. The Tamron 17-70mm also boasts moisture-resistant construction and includes a fluorine coating to repel water and dirt, enhancing its usability in various conditions. While both lenses are designed for durability, the Sony lens’s higher-end build materials and technology may offer an edge in harsher conditions.

Focus and Stabilization

The Sony SEL2470GM incorporates a Direct Drive Super Sonic wave Motor for smooth and quiet autofocus, which is essential for both still photography and video shooting. However, it does not have built-in image stabilization. In contrast, the Tamron 17-70mm lens features Vibration Compensation (VC), which is optimized for use with Sony APS-C cameras, leveraging AI for improved stabilization during video recording. This feature can be particularly beneficial for videographers or photographers who often shoot handheld, making the Tamron lens a more versatile option for those who prioritize stabilization.

Compatibility and Use Cases

The Sony SEL2470GM is specifically designed for full-frame cameras, making it a perfect match for professional photographers working with higher-end systems. Its advanced features cater to those seeking the best optical performance for various photography styles. On the other hand, the Tamron 17-70mm is designed for Sony APS-C mirrorless cameras, making it an ideal everyday lens for hobbyists and enthusiasts. Its versatility and performance in multiple shooting situations make it a compelling choice for those who may not require the premium features of the Sony lens, especially at its significantly lower price point.

Which should you buy?

In conclusion, the choice between the Sony SEL2470GM and the Tamron 17-70mm depends largely on your specific needs and budget. If you're a professional photographer seeking top-tier optical performance and image quality, and you work with full-frame cameras, the Sony lens may be worth the investment despite its higher price tag. However, if you're looking for a versatile, high-speed zoom lens for everyday use on an APS-C camera, the Tamron offers substantial value at a much lower price, making it an excellent option for both amateurs and semi-professionals. Ultimately, your decision should be guided by your photography style, the type of camera you use, and how much you are willing to invest in a lens.
