Performance Comparison

In terms of performance, the SIGMA 18-50mm F2.8 is tailored for versatility and ease of use, while the Sony SEL90M28G excels in macro photography. The SIGMA lens features a minimum focusing distance of 12.1cm, which allows for impressive close-up shots with a maximum magnification of 1:2.8. Conversely, the Sony lens offers a minimum focus distance of 0.92 ft (approximately 28 cm) and a maximum magnification of 1.0x, making it a better option for photographers who focus on detailed macro subjects. The SIGMA lens is ideal for general photography, while the Sony lens is specifically designed for specialized macro work.

Build Quality and Design

The build quality of both lenses reflects their intended use and brand reputation. The SIGMA lens is lightweight and compact, making it easy to carry for long durations. Its rubber-sealed mount enhances its durability, allowing it to withstand challenging shooting environments. On the other hand, the Sony lens is constructed to be dust and moisture resistant, which is crucial for outdoor macro photography. While the SIGMA is more portable, the Sony's robust build quality is advantageous for users who require a lens that can handle the elements.

Optical Quality

When it comes to optical quality, the Sony SEL90M28G stands out with its advanced optics. It includes Nano AR coating to suppress reflections, alongside Super ED glass that minimizes flare and ghosting. This contributes to superior sharpness and contrast, particularly at wide apertures. The SIGMA lens, while designed for high performance, does not have the same level of specialized optical enhancements seen in the Sony lens. For photographers who prioritize image quality, especially in macro settings, the Sony lens may offer a clearer advantage.

Usability and Features

Usability is a significant factor when choosing between these two lenses. The SIGMA 18-50mm is designed for ease of handling, with a zoom range that accommodates various scenarios, from landscapes to portraits. Its lightweight nature makes it suitable for everyday shooting. In contrast, the Sony lens features a sliding focus ring that allows for instant manual and autofocus selection, which is beneficial for macro photography where precision is key. Additionally, the Optical Steady Shot image stabilization of the Sony lens enhances handheld shooting capabilities, making it easier to capture sharp images without a tripod.

Price Comparison

The SIGMA 18-50mm is priced at $599.99, while the Sony SEL90M28G costs $1,048.00. This makes the SIGMA lens about 43% cheaper than the Sony option. For photographers on a budget or those who need a versatile everyday lens, the SIGMA is a more accessible choice. However, the price of the Sony lens reflects its specialized features and superior optical performance, which may justify the higher cost for professional photographers or enthusiasts focused on macro work.

Which should you buy?

Choosing between the SIGMA 18-50mm F2.8 DC DN and the Sony SEL90M28G FE 90mm f/2.8-22 depends significantly on your photographic needs. If you are looking for a lightweight and versatile zoom lens for general photography, the SIGMA offers excellent performance at a lower price point. However, if macro photography is your primary focus and you require top-notch optical quality and features like image stabilization, the Sony lens, despite its higher cost, may be the better investment. Consider your shooting style and budget before making a decision to ensure the best fit for your photography arsenal.
