Sigma 24- vs Sony SEL2470GM E-Mount Camera Lens: FE 24-

Price Comparison

The Sigma 24-70mm F2.8 DGDN II for Sony E is priced at $1,319.00, making it about 27% cheaper than the Sony SEL2470GM, which retails for $1,798.00. This substantial price difference can be significant for photographers on a budget or those looking to invest in multiple lenses. The Sigma offers competitive features for a lower price, making it an attractive option for many users. However, the slightly higher investment in the Sony lens may be justified by its advanced optical technologies and build quality.

Optical Performance

When it comes to optical performance, the Sony SEL2470GM stands out with its advanced design that includes ED and Super ED glass elements. These features help to deliver breathtaking texture and detail while minimizing chromatic aberration. The Sigma 24-70mm F2.8 DGDN II is designed for high sharpness throughout the entire image, making it a strong contender in terms of image quality. However, the unique XA (extreme aspherical) element found in the Sony lens maximizes resolution across the zoom range, which may appeal to professional photographers seeking the best possible image fidelity.

Build Quality and Design

The Sony SEL2470GM is built with a dust and moisture-resistant design, making it suitable for challenging shooting conditions. It also features an AF/MF switch and a focus hold button for enhanced usability. The Sigma lens, while well-made, does not explicitly mention similar weather sealing features. This difference in build quality may influence photographers who often work in outdoor settings or unpredictable environments. The solid construction of the Sony lens may provide peace of mind for users who value durability.

Autofocus Capabilities

Autofocus performance is another critical aspect for many photographers. The Sony SEL2470GM utilizes a Direct Drive Super Sonic wave Motor (DDSSM) for fast and quiet focusing, which is particularly beneficial for video shooting. The Sigma 24-70mm F2.8 DGDN II also provides reliable autofocus but does not specify the same level of sophistication in its focusing system. For those who prioritize quick and silent autofocus, especially in dynamic or low-light situations, the Sony lens could be the better choice.

Versatility in Use

Both lenses offer versatility, suitable for a range of photography styles including portrait, travel, and event photography. The Sigma 24-70mm F2.8 DGDN II is designed to provide high sharpness, making it a great all-rounder. The Sony SEL2470GM, however, emphasizes its capability for capturing natural, lifelike imagery thanks to its advanced glass elements and coatings. This lens is particularly well-suited for those who demand the highest optical performance for a variety of shooting scenarios, from casual to professional.

Image Quality and Bokeh

The image quality produced by both lenses is commendable, but the Sony SEL2470GM is noted for its nine-blade circular aperture, which creates a pleasing bokeh effect. This characteristic can be particularly valuable for portrait photographers looking to achieve beautiful background blur. The Sigma lens does not detail its aperture design as thoroughly, leading to questions about its bokeh capabilities. For photographers focused on achieving stunning backgrounds and separation between subject and environment, the Sony lens may prove to be the superior option.

Compatibility and Accessories

The Sony SEL2470GM is specifically designed for E-mount cameras and comes with several accessories, including a lens hood and protective caps, enhancing its usability right out of the box. The Sigma 24-70mm F2.8 DGDN II is also compatible with Sony E-mount cameras, but it does not mention additional accessories included in its package. For those who appreciate having all necessary accessories readily available, the Sony lens may provide added convenience.

Which should you buy?

Choosing between the Sigma 24-70mm F2.8 DGDN II for Sony E and the Sony SEL2470GM ultimately depends on your specific needs and budget. The Sigma lens is about 27% cheaper and offers high sharpness, making it an excellent choice for budget-conscious photographers. In contrast, the Sony lens justifies its higher price with superior optical technologies, advanced autofocus capabilities, and robust build quality. If you prioritize optical performance and durability, the Sony SEL2470GM may be worth the investment. However, if you seek an exceptional lens at a lower price without sacrificing too much in performance, the Sigma 24-70mm F2.8 DGDN II is a solid choice.
