Sigma offers the Sigma 30 in different mounts to accommodate various camera brands, including Sony E-mount, Canon EF-M mount, and Micro Four Thirds.

Image Quality and Performance
One of the most significant advantages of the Sigma 30 is its exceptional image quality. The lens delivers sharp and detailed images, even at its widest aperture. Colors are rendered accurately, and contrast is excellent. The bright aperture allows for beautiful bokeh (background blur), making it ideal for isolating subjects in portraits.
Sharpness
The Sigma 30 exhibits impressive sharpness across the frame, even at f/1.4 or f/2.8. Stopping down to f/5.6 or f/8 further enhances sharpness, making it suitable for landscapes and architectural photography.
Bokeh
The circular aperture diaphragm of the Sigma 30 produces pleasing and creamy bokeh, especially when shooting at wide apertures. This is a crucial factor for portrait photographers who want to create a soft and dreamy background.
Distortion and Aberrations
The Sigma 30 effectively minimizes distortion and aberrations. Any minor distortion is easily correctable in post-processing software. Chromatic aberration (color fringing) is also well-controlled, ensuring clean and accurate images.
Low-Light Performance
The bright aperture of the Sigma 30 makes it an excellent choice for shooting in low-light conditions. It allows you to capture well-exposed images without having to crank up the ISO, resulting in cleaner and less noisy photos. This is particularly useful for indoor photography, events, and astrophotography.
Autofocus Performance
The Sigma 30 is equipped with a fast and accurate autofocus motor. It quickly locks onto subjects, even in challenging lighting conditions. The autofocus is also quiet, making it suitable for video recording. Some users have found performance varies slightly depending on the camera body it’s paired with.
