Canon releases its ultra-wide EF 14mm f/2.8L II USM lens. With the shortest focal length in Canon’s renowned professional L-series range, the lens boasts a 114° angle of view; exceeded only by Canon’s EF 15mm f/2.8 Fisheye. The Canon lens incorporates aspherical and UD elements to achieve the very highest standards of image fidelity. With the latest Ultrasonic Motor for fast and accurate auto focus and the addition of dust and moisture sealing, it replaces the enormously popular EF14mm f/2.8L USM. The Canon EF 14mm f/2.8L II USM includes an integrated petal hood and redesigned lens cap. In keeping with Canon’s Kyosei philosophy of living in harmony with the environment, the lens features only lead-free glass.

Canon EF 14mm lens - f/2.8L II USM
The L-series is Canon’s flagship professional lens range, designed and built to meet the needs of the most demanding professional photographers. The optics of the Canon EF 14mm f/2.8L II USM and other L-series lenses represent the pinnacle of optical performance, enabling focal length/speed/quality combinations not readily attainable using traditional optical technologies.

Canon EF 14mm f/2.8L II USM features
• Extreme resolving power
• Superb contrast and sharpness across the frame
• Aspheric and UD lens elements
• Large f/2.8 aperture for low-light shooting
• Latest Ring-type Ultrasonic Motor (USM)
• Fast and near silent auto focus with excellent holding torque
• Full-time manual focus override via a large rubber ring
• Super Spectra coatings and optimised lens element shaping
• Large circular aperture diaphragm
• Lens hood and pouch included in the box
• L-series construction

Canon ultra-wide EF Lens
The lens’ ultra-wide 114° angle of view can be used by photographers to dramatic effect. Effective for photographing buildings and other large subjects where the photographer cannot get enough distance to include everything in the frame, the EF 14mm f/2.8L II USM is also ideal for small interiors. The lens’ closest focusing distance of just 20cm allows photographers to get remarkably close to subjects for creative wide-angle shots.

Canon EF 14mm f/2.8L II USM - Aspherical and UD elements
The Canon f/2.8L II USM lens incorporates two aspherical lens elements to ensure high corner-to-corner sharpness throughout the focus range and at wide apertures. Pristine image quality is further assured through the incorporation of an Ultra-low Dispersion (UD) element, used to suppress chromatic aberration and associated colour fringing.

Canon Super Spectra Lens coatings
In addition to optimised lens shaping to reduce reflections and the use of anti-reflective material inside the lens barrel, the EF 14mm f/2.8L II USM employs Canon’s patented Super Spectra lens element coatings. These suppress flare and ghosting – more prone to occur with digital cameras due to reflection off the image sensor. By increasing light absorption, coatings reduce reflections off lens element surfaces to deliver crisp, undistorted images with natural colour balance.

IFA NEWS 2017 REPORT - The IFA International Consumer Electronics Show took place every two years, but since 2006 the IFA show became once again an annual event under Berlin’s famous Funkturm landmark. In the early days, back in 1924 the IFA began in Berlin as the “Great German Radio Exhibition”. In the meantime, the International Consumer Electronics Show has not only become the world's biggest trade show for consumer electronics but also presents the world's largest number of product premieres in consumer electronics and home appliances. At IFA 2009 more than 3 billion Euros worth of orders were generated. IFA 2010 could even surpass this number! The total number of exhibitors at last year’s IFA show was 1164 from 46 countries. The total number of trade visitors was 134194 from 105 countries, quite amazing numbers. The IFA 2010 show news will come to you live from the show floor, so stay tuned!
