Image Quality Breakdown
1. Sharpness Across the Frame
One of the most important factors in evaluating a lens is its sharpness. The Sigma 28mm F1.4 ART is impressively sharp from the center to the corners of the frame, even when shot wide open at F1.4. Here’s a closer look at the sharpness performance:
Center Sharpness: Even at its maximum aperture, the lens delivers excellent sharpness in the center of the image, maintaining high levels of detail and contrast. Whether you're photographing architecture or portraits, the center of your frame will appear crisp and detailed.
Edge and Corner Sharpness: When stopped down to F2.8 or F4, the edge and corner sharpness improve significantly. At these apertures, the lens performs exceptionally well, with minimal optical distortion, making it suitable for landscape and architecture photography where detail at the edges is crucial.
2. Bokeh: Beautifully Smooth Background Blur
A fast aperture like F1.4 offers the potential for gorgeous background blur, or bokeh, and the Sigma 28mm F1.4 ART delivers. The lens produces smooth, creamy bokeh thanks to its rounded 9-blade aperture design. This feature is particularly valuable for portrait photographers and anyone looking to create separation between their subject and a distracting background.
