Optical Performance
When it comes to optical performance, the Sony lens features three aspheric elements that deliver corner-to-corner sharpness, making it ideal for capturing high-resolution images. The f/2.5 maximum aperture allows for low-light shooting and creates a shallow depth of field, enhancing the aesthetic quality of your photos. On the other hand, the VILTROX lens provides an impressive f/1.7 aperture, which, combined with its 84.9° wide angle of view, excels in landscape and VLOG photography. While both lenses offer excellent optical clarity, the Sony lens may appeal more to those prioritizing sharpness and depth of field.
