The purpose of such innovation is to expand the possibilities of photographers with free thought, without being limited by common sense. The history of Canon L-series makes for fascinating reading. It's true that the scientific understanding of optics is now well established, but it would be a mistake to imagine that all the lens designs possible have now been thought of and made.
On the contrary, the pace of change is accelerating as glass makers develop new and ever more exotic materials, and new design and production processes are developed that continue to transform lens manufacturing processes. These are exciting times for lens designers and photographers alike. Fluorite has some terrific properties for lenses, notably the complete removal of residual chromatic aberration and the ability to shorten the total lens length.
However, natural fluorite contains too many impurities to be used for lens manufacturing, as large crystals can't be obtained. Ultra wide-angle lenses require complex designs and sophisticated manufacturing techniques. Fast prime lenses are not a modern invention! In , this lens offered the world's widest aperture for a 35mm single lens reflex camera. A floating lens construction was used to ensure image quality even at short focus distances, and the USM UltraSonic Motor autofocus motor offered high-speed, silent autofocus with full-time manual override.
This was the first 10x zoom lens for an interchangeable lens SLR and proved a powerful and versatile lens for sports photography, where speed and manoeuvrability are paramount. Designed with a six-group configuration, this lens used the fifth group for zooming, and achieved both a high zoom ratio and a compact design. Two UD Ultra-low Dispersion lenses provided good correction of chromatic aberration, high resolution and high contrast, and it came with an easily adjusted tripod foot.
Handheld telephoto photography is always a risky business for sports and wildlife photographers because of the potential for camera shake, but when Canon introduced its IS Image Stabilisation system for the first time on a professional lens, it offered effective shake compensation of two stops. This made handheld photography possible in situations where a tripod might otherwise have been needed, and offered photographers much more mobility.
Chromatic aberration was suppressed with two UD lenses and the lens was developed for high resolution and contrast. Lens coatings are not the most glamorous-sounding lens technology, but they are one of the most important, playing a vital part in the suppression of ghosting, flare and contrast loss. The SWC coating adopted for this lens has a structure finer than the wavelength of visible light, which was the first time this had ever been done. This minimised flare and ghosting caused by large angles of incidence, which could not be prevented with regular coatings.
The SWC system was earmarked as one of Canon's key technologies for future development. Macro photography poses special problems for image stabilisation systems because it introduces a second type of potential camera movement parallel to the camera position. Dust, rain, sand, and the like are far less likely to get into the mechanisms or between the glass elements and mess things up.
L-series lenses have better autofocus and focus control than non-L lenses. Their autofocus tends to be faster and more accurate.
They also have full-time manual focus even in autofocus modes you can twist the focus ring to adjust and focus distance scales on the lens, which a lot of non-L lenses lack. This means you can easily share filters—such as neutral density filters or polarizers—between all your lenses. Your skill as a photographer matters far more than the lens you are using. L-series lenses are expensive.
You can get some great glass for a lot less than that. L-series lenses are designed for working photographers who view new gear as an investment in their business. Image Credit: William on Unsplash.

The build quality combined with wide minimum apertures usually result in Canon L lenses being heavy. The image quality of the Canon L lenses is generally as good as it gets. All are excellent. Full Frame camera body owners will especially find L series lenses to be on average significantly sharper toward the edges of the frame compared to lesser lenses.
In general, Canon L series lenses focus fast. The wide maximum apertures smallest number and fast, quiet USM motors Ultrasonic Motors enhance focusing speed. Many in the Canon L lens series are white in color. According to Canon, this reduces heat gain when a lens is used in bright, direct sunlight. White reflects more light than black - thus, less heat gain.
