Obiettivo Sigma 24-105mm f/4 DG OS HSM Art x Canon Lens 24-105

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.
