The lens was later made available in the regular black finish from December 1997 for 35mm EOS users who are interested in buying one for their cameras. The optical quality of this lens is superb due to the use of a glass-molded aspherical element that enable the zoom lens to obtain high quality images. Aside from being able to render high quality images, the aspherical element also helped suppresses barrel distortion and high contrast is maintained at all focal lengths. By having multiple lens groups move during zooming, the lens could be made compact and lightweight. It has 15 elements in 12 groups in its lens construction with the fourth element being of the aspherical type and the lens itself uses a 67mm filter. The front of the lens barrel is of the non-rotating type during focusing so the use of a Circular Polarizer (PL-C) or Neutral Density (ND) filters are made easier. For those who are not familiar with using 24mm focal lengths, it may take sometime getting used to seeing your pictures made with such optics. With the EF 24-85mm zoom lens, the ability of zooming the focal lengths from its 24mm wide-angle end all the way to its 85mm short telephoto will, nevertheless, take your breath away. These series of five pictures of a section in Kuala Lumpur show the angle-of-views of how wide the 24mm lens can include in to how close it can zoomed in at the telephoto end. Section of KL being photographed from focal lengths from 24mm, 35mm, 50mm, 70mm and 85mm. << Back to Main . 1 . 2 . 3 . 4 . 5 . 6 . 7 .
