The image sensors of digital SLR cameras continue to offer higher and higher resolution, and photographers are looking for high-performance lenses that leverage these sensors’ full power. In the case of zoom lenses as well, which are a dependable go-to in a wide variety of photographic conditions, photographers want convenience combined with exceptional optical performance. The new SIGMA 24-105mm F4 DG OS HSM zoom lens more than fulfills these requirements, offering exceptionally stable high resolution from wide-angle to medium telephoto photography.
While featuring a large-aperture 82mm filter size, this lens minimizes optical aberrations and avoids reduced peripheral brightness, an issue that tends to affect lenses with similar specifications. Each lens is checked with SIGMA’s proprietary A1 MTF (modulation transfer function) measuring system to ensure it offers exceptional quality for the high-megapixel era. Try this new high-performance zoom for yourself, and experience SIGMA’s uncompromising pursuit of high resolution.

Vignetting
The x-axis represents image height (distance from center of image in mm), and the y-axis represents the relative illumination at the edge of the image (with illumination at the center of the image defined as 100%). When relative illumination is low, the corners of the image appear dark, resulting in vignetting.
Distortion
Rounded diaphragm
When photographing with point light sources such as electric lights or reflections on a body of water in the background, the rounded 9-blade diaphragm helps produce an attractive bokeh effect—even at large-aperture settings.
