Canon EF 28mm f/1.8 USM Lens, USA

With the large maximum aperture, excellent background blur is possible even with a fast shutter speed. The aspherical lens element makes the lens compact and corrects spherical aberrations. The image is sharp even at the edges. Lead-free glass is used. Fast and wide The lens' large maximum aperture of f/1.8 ensures photographers can use fast shutter speeds in a variety of different lighting conditions, and blur backgrounds by controlling depth of field. An aspherical lens element corrects distortion and ensures the image is sharp across the frame. When fitted to EOS cameras with APS-C sized sensors, the EF 28mm f/1.8 USM offers a field of view equivalent to a 45mm lens on a full-frame camera, making this an ideal fast-aperture standard lens. 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 color 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 EF 28mm f/1.8 USM passes distance information back to a compatible EOS camera's E-TTL II flash system to ensure optimal flash metering.
