The lens also comes with a new multilayer coating that offers a great color performance and at the same time reduces ghosting or flare created by reflections. By design, the Sigma 100-300 will also maintain a minimal light fall-off and ensure that the peripheral brightness is of superior quality. You should expect high optical performance, which is displayed all through the zoon range.
With the Sigma 100-300, you will not worry about aberrations because the two SLD glass elements in the front and rear of the lens enable optical corrections to offer superior quality all through the zoom range. The lens is also available with an inner focusing system, which is responsible for eliminating the rotation of the front element of the lens.
Users of the Sigma 100-300 will benefit from the smooth movement of the zoom and focus rings because they come with the right resistance levels. The rings are made of rubber and this makes it better to handle and easy to turn. The focusing ring will end in soft stops on the different spectrum of focus. Sigma 100-300 also comes with 150 degrees of turning fidelity, making it easier for the users to focus the lens manually. The filters attached to it will not rotate as the lens focuses.
The Sigma 100-300 is designed with a control switch that allows the users to easily enable or disable auto focus. There is a windowed distance scale that indicates the distance in meters and feet, but there is no depth of field or infrared markers on the lens. Thanks to the HSM, the auto focus process is not only quiet but also fast. It will take the users a short time to get to infinity from close-focus. The speed is also seen in point to point focusing, and the users can override the autofocus by rotating the focus rings.
When it comes to storage, the individuals will enjoy an easy process. The lens hood with a petal shape will reverse easily onto the front of the lens. The hood also comes with a ribbed texture that helps in the reduction of light that strikes on the Sigma 100-300 lens' front element.
