Description

With a simple flick of a switch, the zoom range can be quickly increased to 280-560mm (f/5.6). This capability is extremely useful in applications where it is not possible to change lenses quickly, while also protecting delicate equipment such as a digital SLR camera’s image sensor in environments with dust and high humidity.

Extender 1.4X incorporates one fluorite and four UD lens elements, which provide excellent correction of chromatic aberration throughout the entire zoom range for professional quality images with high resolution, contrast and colour fidelity, while a 9-blade circular aperture helps deliver beautiful, soft backgrounds

It utilises inner focusing, ring USM, a high-speed CPU and optimised AF algorithms for fast and accurate autofocusing.

With Power Focus mode, focus shifts are quiet and smooth, which is essential for film making. Image stabilisation is effective up to four shutter speed steps, with three image stabilisation modes (standard, panning, and during exposure only) providing excellent results for a wide range of subjects.

Optimised lens placement and coatings deliver outstanding colour balance, while helping to minimise ghosting and flare.

The lens is highly resistant to dust and water, enabling shooting even in harsh conditions. A fluorine coating on front and rear lens surfaces repels dust particles and makes the lens easier to clean.
