Zoom objektiv Sigma 24-105mm f/4.0 DG OS HSM ART pro Canon

SIGMA 24-105mm f/4.0 DG OS HSM ART

The Super Multi-Layer Coating of the Sigma 24-105mm reduces flare and ghosting to ensure sharp, high contrast images even in backlit conditions, while its Hyper Sonic Motor ensures silent and smooth focusing alongside full-time manual override for precise adjustments. This lens features a minimum focusing distance of 45 cm and is compatible with Sigma's USB dock, allowing photographers to update the firmware and change focus parameters using Sigma's own Optimisation Pro software.

Superior image quality
Standard lenses with a high zoom ratio tend to show astigmatic aberration, field curvature, distortions, and colour aberration. In order to compensate for these, various types of high-performance lenses, such as FLD, SLD, and glass-molded aspheric lenses (including double-sided aspheric lenses), have been included in the optical system. In addition, it suppresses chromatic aberration very effectively at the telephoto-end and achieves superior image quality throughout the zoom range. This lens overcomes low peripheral brightness that is common for those lenses with similar specifications. Also, the wide filter size of 82 mm contributes to its superior optical performance.

Convenient handling
The lens's wide zoom ring ensures convenient handling. Putting the zoom ring in front allows the lens barrel to be more compact. The inner focusing system eliminates front lens rotation, enhancing the lens's stability and allowing use of Circular Polarizing filters.

Designed to minimize flare and ghosting
Flare and ghosting were thoroughly measured and monitored from an early stage in the lenses development to establish an optical design which is resistant to strong incidental light such as backlighting. The Super Multi-Layer Coating reduces that flare and ghosting and provides sharp, high-contrast images even in backlit conditions.

Minimum focusing distance of 45cm
With a minimum focusing distance of 45 cm and a maximum magnification ratio of 1:4.6, this lens is excellent for close-up photography.

Hyper Sonic Motor
The HSM (Hyper Sonic Motor) ensures silent, high-speed AF function. Through its optimizing AF algorithm, smoother AF is achieved. It also has full-time manual focusing capability which allows focus adjustment by simply rotating the focus ring.

Incorporating Rounded diaphragm
The 9-blade rounded diaphragm creates an attractive round bokeh at large-aperture settings.
