This lens combines the highest levels of optical performance and photographic expression with equally fine functionality and usability. It embodies the concept of the Sports line, which features outstanding action-capture performance. Fully customisable, it allows the photographer to create their own specification. It is an ideal choice for photographing sports events, animals and natural environments, airplanes, motorsports and even portraits. It greatly empowers photographic expression, allowing photographers to capture those crucial shots.
Sports line lenses deliver high action-capture performance
Sigma is organizing all its interchangeable lenses into three product lines; Contemporary, Art and Sports. While offering sophisticated optical performance and expressiveness, our Sports line lenses deliver high action-capture performance, enabling photographers to get exactly the shots they want. With their high-level optical performance and expressive power, these lenses can capture fast-moving subjects, even at distance. This high-performance line also offers a variety of functions to aid the photographer in challenging conditions and scenarios. The SIGMA 120-300mm F2.8 DG OS HSM is the first product from the “Sports” line. Besides sports photography, the lenses are also perfect for nature shots featuring birds, wild animals and other wildlife, and for capture of aircraft, trains, racing cars and more. Another major feature of our Sports line lenses is their wide range of customisation functions: using the software provided, all sorts of settings can be tailored to the personal preferences of the photographer.
Dust-proof and splash-proof construction
For professional purposes, we have achieved excellent durability by incorporating dust-proof and splash-proof parts for joint parts, such as mount attachment, manual ring, zoom-ring, switches for customization and external switch panels. It prevents dust and dirt from entering the lens. Also, the usage of the zoom ring and focus ring is well positioned for shooting situations.
High image quality close to fixed focal length lens
This lens incorporates 2 FLD (“F” Low Dispersion) glass elements, which have performance equal to fluorite, 1 SLD (Special Low Dispersion) glass element, and compensate for the colour aberration at the utmost. The design also compensates for sagittal coma flare and minimises the blurring of a point light source in peripheral areas. It offers very high image quality, close to fixed focal length lens.
Incorporation of focus limiter
Excellent usability is achieved by incorporating inner focusing and zooming that requires no change in the length of the lens for focus and zoom. It is possible to use with a rounded filter, such as a Circular Polarizer, as the front part of the lens is fixed. Due to the focus limiter offering adjustable range of auto focusing, this lens can provide fast focus setting. The USB dock enables users to change the range of the auto focusing at the discretion of users’ creativity.
Newly developed “USB DOCK” exclusively for new product lines
Based on these new lines, we have developed special software (SIGMA Optimization Pro) that can update the lens firmware and adjust parameters such as focus. In addition, the lenses from our Sports line have customisable AF speed, focus limiter and OS function. The “Custom Mode Switch” is the device for further customisation on the dedicated lenses.
Ease of use
Many parts of this lens have been designed for comfortable usage. For example, the design of the zoom ring is concerned with a texture when you hold it, the position of printed letters and the 4 control switches with integration-considered shape of the screws. Included accessories such as the removable lens hood and the newly designed tripod collar with strap ensure added ease of use
Flare and ghosting conscious design
In order to achieve high rendering on this flagship lens, flare and ghosting were thoroughly measured from an early stage to establish an optical design which is resistant to strong incident light such as backlight. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions.
Excellent in handheld photography for telephoto shooting
This lens incorporates the OS system which offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible, ensuring the excellent use in handheld photography for telephoto shooting. The OS system has two modes – OS mode 1 is suitable for general photography, and OS mode 2 is best for panning shots of subjects such as planes or racing cars. It is possible to adjust the OS using the optional USB DOCK.
