Additionally, it offers an instant manual/auto focus selection via a sliding focus ring, enhancing user control. Although the Sigma 10-18mm F2.8 does not mention stabilization features, its autofocus system is designed for quick and accurate focusing, particularly beneficial for capturing moving subjects in dynamic environments.

Weight and Portability

Weighing in at 602 g (21.3 oz), the Sony SEL90M28G is relatively heavy compared to traditional lenses but is still manageable for a macro lens. In contrast, the Sigma 10-18mm F2.8 is designed for portability, being the lightest ultra-wide-angle zoom lens for APS-C cameras. This makes it an excellent choice for travel photographers who prioritize weight without sacrificing performance. The weight difference might influence a photographer’s decision based on their shooting style and travel plans.
