Marketing meterials from Canon: http://www.usa.canon.com/eflenses/technology/lseries.html

"Canon "L" series lenses are generally agreed to be the best out there. They are expensive however. Some 3rd party lenses are also quite good for half the money. Get the Canon if you have the bucks, but if value is important, look at Sigma and Tokina's high-end lines." Quoted from http://pic.templetons.com/brad/photo/dslrlens.html

The "L" may stands for luxurious (in terms of price) too. : )

在 1987 年，Canon 的 EOS 系列取代了舊有的 FD 系列之後，Canon 可算是踏進新的紀元。大量的新科技運用在 EF 鏡頭系列上，如驕傲之作 USM (Ultrasonic Motor) 內置鏡身馬達、 EMD (Electromagnetic Diaphragm) 電子光圈葉、首創的 IS (Image Stabilizer) 防振動器、 L 鏡系列所採用的高質素 UD (Ultra-Low Dispersion) 低色散鏡片、 ASP (Aspherical) 非球面鏡片、珍貴的 CaF2 (Calcium Fluoride) 塋石鏡片等等。


以下為新近大部份的 EF鏡頭 和 L系列鏡頭 的規格及資料，內容大部份參閱於 EF Lens Work II。
