Sigma's 500mm F4 lens designed for DSLR cameras was of course brighter by an aperture, but it was considerably larger and weighed almost two kilos more. With modern cameras, the aperture is well managed and at the same time the lens offers more effective stabilization and autofocus.
The long focal length allows you to photograph wildlife or even small birds from a distance and in detail. The subject is sharp and the backgrounds, if desired, at full aperture, bring the subject out nicely.
The small size has been achieved with special lenses, but there are no Diffractive optics or DO lenses used like Canon, for example, so the blurry areas behind the subjects are softened more beautifully and this is a good thing because most subjects are like this.
Thanks to its small size and weight, the lens works great for handheld shooting, meaning it tracks moving subjects well.
Handheld photography is also aided by an optical image stabilizer, which has a power of five aperture values. The stabilizer is Sigma's latest version containing OS2 software and has two modes, Mode 1 for normal photography and Mode 2 when following subjects such as athletes or vehicles by panning, i.e. following in a certain direction. Sigma's stabilizer can take into account the tracking regardless of which direction the movement is proceeding, i.e. also diagonally and also works in vertical photography.
Focusing is handled by the HLA High Response Linear Actuator focus motor. This means that the lens has Sigma's latest technology. This type of lens is often used to photograph fast-moving subjects, whether it's an athlete, a bird or an airplane, so speed is beneficial. The lens supports all of Sony's body autofocus features, i.e. Eye AF and newer features such as AF Assist work.
The Sigma 500mm F5.6 is conventional in terms of usability, meaning that stabilizer adjustments and focus limitation can be made directly with buttons. In addition, there are three programmable AF-L buttons on the front of the lens for activating the focus feature, for example. The lens has an aperture control ring, and like the Sony, this control ring also has an automatic setting and lock.
Weather protection is good, like Sigma's Sports series.
