Sometimes this can mean in low light or even at night. Professional photographers are often forced to shoot in less than ideal lighting conditions. Accordingly, the L-series lenses feature liberal use of rubber sealing at interface areas, such as the lens-to-camera junction, external switches, and around zoom and focus rings to prevent water getting in and destroying the lens’ electronics. This means a rugged build quality that will endure the knocks of everyday use, and weather sealing to protect against every type of adverse conditions. A lens destined for professional use must be able to withstand the rigours of a professional photographer’s working life.
Optical performance is only half the story. If it does not have this red ring, it is not part of the L-series lens range.

Canon uses three technologies in its L-series lenses to produce the sharpest, clearest pictures: fluorite elements, aspherical elements and UD optical glass elements. The Canon EF 100mm f/2.8L Macro IS USM was one of the most respected lenses in its DSLR line, offering top image quality, impressive image stabilization, and no-fuss autofocus, all at a very. L-series lenses meet the requirements, and needs of professionals. They enable quick and silent auto focus of Canon Lenses.
Being ring-shaped, they are ideally suited to the shape of the lens barrel, their focusing speed is very controlled and they are stable across a wide range of temperatures, from -30°c to 60°c. Ring-type motors are highly efficient and feature a low power consumption to extend the camera battery life. The EF100mm f2.8L Macro IS USM features a single UD lens to provide the highest image quality possible.

A faster /2.8 upgrade designed for the EF mount came in 1990, a version with the ultrasonic motor (USM) was released in 2000, and image stabilization was added in 2009 with the EF 100mm f/2.8L. UD lens elements are used to correct for colour aberration and produce a high contrast image with good sharpness and definition. A 100mm macro lens that captures images at 1x without accessories has been available to Canon users since 1979, beginning with the Macro FD 100mm f/4.
