Sigma 28- vs Sony SEL90M28G FE

Price Comparison

The Sigma 28-70mm F2.8 DG DN for Sony E is about 17% cheaper than the Sony SEL90M28G FE 90mm f/2.8-22 Macro G OSS, with a current price of $859.95 compared to $1,048.00. This price difference may attract budget-conscious photographers looking for quality without breaking the bank. While the Sigma lens offers a versatile zoom range suitable for various shooting scenarios, the Sony lens is positioned as a premium macro option, justifying its higher price point with specialized features for close-up photography.

Optical Performance

Both lenses are designed to deliver exceptional optical performance, but they cater to different needs. The Sigma 28-70mm features a large f/2.8 aperture across its zoom range and is known for its outstanding image quality, comparable to higher-end Art line lenses. In contrast, the Sony SEL90M28G excels in macro photography with a 90mm focal length and a bright f/2.8 maximum aperture, providing a maximum magnification ratio of 1.0x. Photographers focusing on detailed close-up shots may find the optical advantages of the Sony lens particularly appealing.

Build Quality and Design

When it comes to build quality, the Sony SEL90M28G boasts a dust and moisture-resistant design, making it suitable for challenging shooting environments. Its advanced spherical elements and Super ED glass contribute to corner-to-corner sharpness while minimizing flare and ghosting. The Sigma 28-70mm, on the other hand, is lightweight and compact, emphasizing portability without compromising on quality. While the Sigma lens is designed for everyday use, the Sony lens is crafted for professionals needing durability and reliability in diverse conditions.

Focusing Mechanisms

Focusing capabilities differ significantly between these two lenses. The Sigma 28-70mm features internal focusing, allowing for quick and precise adjustments without changing the lens length. Additionally, it includes a Focus Mode Switch for instant transitions between auto and manual focus. Conversely, the Sony SEL90M28G incorporates Optical Steady Shot image stabilization, which is crucial for handheld macro shooting. Its sliding focus ring enables quick manual/auto focus selection, enhancing versatility in various shooting situations.

Special Features

Unique features set these lenses apart. The Sigma 28-70mm includes a Nano Porous Coating that enhances image quality by reducing flare and ghosting, making it ideal for bright environments. In comparison, the Sony SEL90M28G also utilizes Nano AR coating for effective reflection suppression, alongside a 9-blade circular aperture that contributes to its renowned bokeh quality. This bokeh effect is particularly significant for photographers aiming to create aesthetically pleasing backgrounds in portrait and macro photography.

Weight and Portability

The Sigma 28-70mm stands out for its lightweight and compact design, making it an excellent choice for photographers who prioritize portability. This aspect is particularly beneficial for travel or daily shooting situations where carrying heavier equipment can be cumbersome. The Sony SEL90M28G weighs in at 602 grams (21.3 oz), which is relatively heavier compared to Sigma, but this weight is often a trade-off for the advanced features and build quality it offers. For those who frequently change locations or shoot for extended periods, the Sigma may provide a more comfortable experience.

Compatibility

Compatibility is essential when choosing a lens, and both offerings are designed for Sony E-mount cameras. The Sigma 28-70mm is specifically tailored for Sony E, making it a versatile option for a wide range of photography styles. The Sony SEL90M28G, however, is optimized for the α7 series and other full-frame E-mount cameras, providing a perfect match for professionals using this system. This specialized focus may make the Sony lens more appealing for users heavily invested in the Sony ecosystem, particularly those who shoot macro.

Which should you buy?

Ultimately, the decision between the Sigma 28-70mm F2.8 DG DN and the Sony SEL90M28G FE 90mm f/2.8-22 Macro G OSS boils down to your specific photography needs. If you are looking for a versatile and budget-friendly option for everyday photography, the Sigma lens, priced at $859.95, is a compelling choice. However, if your focus is on macro photography and you require advanced features like greater optical stabilization and superior bokeh, the Sony lens at $1,048.00 may justify its price. Consider your shooting style and whether you prioritize versatility or specialized features when making your selection.
