Detailed Features
A practical and portability telephoto lens
The EF 85mm f/1.8 USM produces images that are sharp and clear at all apertures. A virtually circular aperture diaphragm gives out-of-focus regions a softer, more even feel, and lets in-focus subjects stand out against a blurred background. The lens features a non-rotating front element during focusing, enabling specialist filters (such as polarisers and graduates) to be used.
Large f/1.8 aperture
A large maximum aperture of f/1.8 lets photographers shoot hand-held in difficult, low-light conditions, as well as restrict depth-of-field for creative effects.
Ultrasonic focusing
A ring-type ultrasonic motor drives autofocus extremely quickly, and in near silence. Excellent holding torque ensures the point of focus is reached accurately, without overshooting. Furthermore, full-time manual override is available, making it possible to adjust focus without leaving AF mode.
