The Sigma 24-105mm F4 DG HSM Art lens is a premium lens designed for full frame cameras and will also work with APS-C sensors with an effective increase in focal length. The 24-105mm F4 is a highly versatile focal range and staple everyday lens. With the increasing resolution power of new sensors, it is designed to bring out the true potential of evolving camera technology. Sigma’s 24-105mm f4 includes proprietary Sigma technology including our Hyper Sonic Motor (HSM) which ensures fast, quiet and accurate autofocusing. A 9 blade rounded diaphragm creates beautiful background blur, while FLD and SLD glass elements compensate for various aberrations, distortion and curvature. The use of Thermally Composite Material (TSC) reduces size and weight and as part of the new Global Vision design, it is compatible with the Sigma USB dock for further customization and the new Mount Conversion Service. 

Art Lens

Engineered for those who see photography as an expression of self, Sigma’s Art line offers sophisticated optical performance and abundant expressive power to deliver faithfully on your artistic vision.

ASP – Aspherical

The aspherical lens complex allows freedom of design, improved performance, a reduced number of component lenses and a compact size.

DG - DG for Digital

Sigma's DG lenses are specifically designed to deliver the ultimate level of performance on full frame digital SLRs. Sigma DGs also maximize the abilities of 35mm SLR cameras and APS-C size DSLRs. Thanks to a complete and comprehensive approach to the correction of chromatic aberrations, you will experience incredible image clarity and smoothness. Specific attention was paid to helping eliminate color fringing often caused by lateral chromatic aberration, a problem that is magnified at high resolution in digital photography. DG lenses provide exceptionally high contrast along with subtle gradations in tone and color. Super Multi-Layer Coating, along with Sigma's optimized optical design work to reduce reflections between the image sensor and the lens surfaces. The large image circles of DG lenses mean there will always be enough peripheral illumination to avoid vignetting.

OS - Optical Stabilizer

This function utilizes a built-in mechanism that compensates for camera shake. It dramatically expands photographic possibilities by alleviating cameras movement when shooting by hand held camera.

HSM - Quiet and Fast Autofocusing

HSM lenses employ a motor powered by ultrasonic waves that produce a quiet, yet high-speed AutoFocus. You can enjoy high performance with low noise in a variety of shooting situations.

IF – Inner Focus

To ensure stability in focusing, this lens moves the inner lens group without changing the lens’ physical length.

Excellent Handling

Positioning the zoom ring at the front of the lens helps make possible a slim barrel design. In addition, the wide, thick zoom ring contributes to the lens’s high usability. Thanks to SIGMA's inner focus technologies, adjusting the focus and zoom rings does not change the length of the lens, resulting in excellent handling. Since the front of the lens does not move, the lens can be used with a circular polarizing filter.

USB Dock Compatibility

The Sigma 24-105mm F4 DG HSM Art lens is compatible with a Sigma USB Dock - Use SIGMA Optimization Pro, a special software that updates the lens firmware and adjusts parameters, such as focus and full-time MF.
