*Recommendations are based only on the features necessary to perform the application successfully and do not take into account the relative image quality of different lenses
High foreground to background compression of Static/Slow-moving subjects
High focal lengths reduce the perceived distance between foreground and background or they can be used for better magnification of subjects that are not possible to get closer to. When operating telephoto lenses at 300mm or above focal lengths without image stabilisation or camera support, it is necessary to use shutter speeds over 1/250 sec, making those lenses only suitable for daylight exposures.Technologies
OS (Optical Stabilizer) Function
The OS (Optical Stabilizer) function uses two sensors inside the lens to detect both vertical and horizontal movement of the camera. This function works by moving an optical image stabilizing lens group, to effectively compensate for camera shake. To handle all types of shooting conditions, the system has two optical stabilizer modes. Mode 1 determines camera shake in vertical and horizontal panning and compensates for image blurring. It is therefore effective for taking general photography or for shooting landscapes and other static subjects. Mode 2 detects vertical camera shake and compensates for blurring. It is effective for panning the camera to photograph moving subjects such as motor sports.
HSM (Hyper-Sonic Motor)
HSM stands for ""Hyper Sonic Motor"". The HSM motor is driven by ultrasonic waves and it makes auto focusing, precise, silent and high-speed. Sigma's HSM version lenses are available only for AF Sigma, Canon and Nikon AF cameras.
DC (DC Lens)
These are special lenses designed so that the image circle matches the smaller size of the image sensor of most digital SLR cameras. Their specialized design gives these lenses the ideal properties for digital cameras, the compact and lightweight construction is an added bonus! including compact and lightweight construction.
