Design and Build Quality

The Sigma 30mm lens boasts a compact design, making it portable and easy to carry for everyday use. Its construction includes nine rounded diaphragm blades, which contribute to pleasing bokeh and improved optical performance. The lens hood and both front and rear caps are included, enhancing its usability and protection.

Conversely, the Sony SEL90M28G lens features a robust build that is dust and moisture resistant, making it suitable for challenging shooting conditions. Weighing 602 grams (21.3 oz), it is heavier than the Sigma but is designed for more intensive use, particularly in macro photography. The advanced optics and coatings in the Sony lens, such as Nano AR coating, help suppress reflections and enhance image clarity.

Optical Performance

The Sigma 30mm F1.4 lens is engineered to provide sharp, high-quality images with a wide aperture that excels in low-light environments. This lens is particularly noted for its ability to produce a shallow depth of field, ideal for portraiture and creative photography. The stepping motor ensures fast and accurate autofocus, beneficial for both stills and video work.

In comparison, the Sony SEL90M28G lens delivers outstanding optical performance with corner-to-corner sharpness, thanks to its advanced spherical elements and Super ED glass. The lens's maximum aperture of F2.8, while narrower than the Sigma's, still provides excellent low-light capability and allows for beautiful background blur. It is particularly tailored for macro photography, offering a maximum magnification ratio of 1.0x, which makes it perfect for capturing intricate details.

Autofocus System

The autofocus system in the Sigma 30mm lens is designed with a stepping motor that provides quick and precise focus adjustments, making it suitable for video and fast-paced photography. This feature is essential for photographers who need reliable performance in dynamic environments.

The Sony SEL90M28G lens features Direct Drive SSM (DDSSM), which allows for quiet and precise focusing. This is particularly advantageous for wildlife and macro photographers who require stealth and accuracy. The lens also includes an instant manual/auto focus selection via a sliding focus ring, adding to its versatility for different shooting situations.

Price Comparison

At $419.00, the Sigma 30mm F1.4 lens is about 60% cheaper than the Sony SEL90M28G, which is priced at $1,048.00. This significant price difference makes the Sigma an appealing option for hobbyists and those on a tighter budget. The affordability of the Sigma lens does not mean a compromise on quality; it still offers impressive features that cater to a wide range of photography needs.

On the other hand, the Sony lens, while more expensive, justifies its price with advanced features, superior optical performance, and a build quality that meets the demands of professional photographers. Thus, the choice between these two lenses will largely depend on the user's budget and specific photography requirements.

Compatibility

The Sigma 30mm F1.4 lens is specifically designed for SONY E-mount APS-C mirrorless cameras, ensuring compatibility with a wide range of devices within this category. It is particularly suited for users of models like the Sony Alpha series who want to enhance their photography without investing heavily.

In contrast, the Sony SEL90M28G lens is optimized for full-frame E-mount cameras, making it ideal for professional photographers who use Sony’s α7 series and other full-frame models. This makes the Sony lens a better fit for those needing a high-performance macro lens for detailed work in portrait or product photography.
