Canon EF 85mm f/1.8 USM

פירוט תכונות

• 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.

• Compressed perspective in portraiture

  The short telephoto focal length of the lens slightly compresses perspective, reducing the size of prominent facial features for a flattering result.

• 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.

• Super Spectra coating

  Super Spectra coatings ensure accurate colour balance and enhance contrast. They also reduce flare and ghosting – a common problem caused by light bouncing off a camera's sensor.

• Integration with E-TTL II flash metering

  The lens passes distance information back to a compatible EOS camera's E-TTL II flash system to ensure optimal flash metering."
