Revolution in image quality

Digital SLR camera pixel counts, print output sizes, large monitors and more are growing and evolving. As cameras improve and means of playback become more diverse, people expect more and more resolving power in lenses every day. The aim of designing new-generation L-series lenses has been to improve resolving power and contrast dramatically. That's why these lenses are now ready to satisfy coming generations of photographers who won't compromise on image quality.

Image quality of large-aperture lenses with aperture fully open

The quality of images shot with fully open aperture is considered to be the purest expression of a lens's optical performance. The new generation of L-series lenses puts superior resolution and contrast performance on display in images taken at all aperture settings. To produce outstanding background blur in photos, the lenses give you flexibility to shoot even with fully open aperture, without troubling yourself to set ISO sensitivity and shutter speed.

Suppression of chromatic aberration

Axial and magnification types of chromatic aberration are minimized by the use of special optical elements such as fluorite, as well as UD (Ultra-low Dispersion) and Super UD optical elements. As a result, color fringing is minimized while high resolution and high contrast are realized.

Image quality improved in peripheral areas

Special optical elements, such as UD and Super UD optical elements, plus the latest optical design enable the lens to suppress various types of aberrations that tend to occur in peripheral areas of images. Field curvature and astigmatism are minimized while high-quality images are vivid and clear throughout all areas of pictures. Moreover, this optical technology made it possible to develop the EF16-35mm f/4L IS USM and EF11-24mm f/4L USM ultra-wide-angle lenses.

Reduction of ghosting and flare

Placement of lenses and application of coating are optimized taking into account the reflective characteristics of the image sensors in a digital SLR camera, which bounces some of the light that reaches the sensor. Moreover, Canon's new-generation special coating technologies, such as SWC and ASC, are employed for effective control of ghosting and flare, and prevent reflection between lenses when there is a strong light source or when light enters at a large angle of incidence.
