The 135mm lens is considered to be a short telephoto lens. This is the first accessory lens added by many new owners of a systems camera. There are several good reasons. This is one of the most versatile lenses - good for distant subjects and excellent for close-ups, sporting events, landscapes and portraits. You can shoot from as close as ~5 feet or from long distance, under just about any average light conditions. The lens is compact and lightweight.

Features
Construction
Painstaking hand craftsmanship, the highest quality raw materials and the most advanced technological know-how are combined in the manufacture of each lens.
In the beginning, lens design required logarithmic tables, slide rules- and great patience. It often took three competent designers several years of steady work to complete the computation of a single 4-element lens.Fine optics alone cannot make a superior lens; the mechanical components are equally important.
All mechanical components are precision machined to microscopic tolerances. Specially lubricated, wear-resistant metals assure consistently accurate apertures year after year. Screw mounts are the most precise method of holding a lens firmly in place.

Infra-Red Index
When taking infra-red photographs, the focal point shifts slightly, and therefore, the lens must be extended accordingly. The difference varies depending on the lens, and it is indicated by the small "R" index or short orange line. In infra-red photography, use this infra-red index. First, focus your lens on your subject. Determine the lens-to-subject distance from the distance scale. Then match your "R" mark by turning the distance scale accordingly. Like the photo to the left, if your subject is in focus at infinity, turn the distance ring and move infinity mark to the "R" index. Also, remember to use an R2 (red) or O2 (orange) filter and special infra-red film in this special photography.
