CANON EF 85mm f1.8 USM Lens
The EF 85mm f1.8 USM Lens from Canon is a highly practical medium telephoto prime lens ideal for a range of applications including portraiture. Its fast f/1.8 maximum aperture is effective in low light and ideal for shallow depth of field focus control. An ultrasonic autofocus motor (USM) provides fast, smooth and quiet AF action and because the front lens group does not rotate during focusing, polarizing and special filter effects can be used effectively.
- Fast Maximum Aperture
- A bright f/1.8 maximum aperture makes this lens a good choice for low-light photography and provides shallow depth of field control, ideal for portraiture with pleasing background blur.
- Ultrasonic Autofocus Motor
- With an ultrasonic motor (USM), the autofocus action on this lens is fast, smooth and quiet.
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.
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.
