The 35mm lens is considered to be an wide-angle lens.  Now often found as the "normal lens", it is a great lens for shooting in congested areas, for creating or enhancing the depth of a subject.  It is a compulsory component in a well equipped system.   With its capacity to work well it low-light situations, the scope of photographic opportunities expands!  Compared to a 50mm "normal" lens with a 46 degree angle of view, this lens opens up the scene captured from the same vantage point.  Straight lines do not appear curved as they would with a "fish-eye" lens. When making a photograph the scene will appear very normal but with greater depth.

Construction

Stunning Like-New Condition! 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.   Vivitar lenses are highly regarded as an affordable alternative to prime lenses and provide long life and reliable operation, not to mention great images!.

Has this lens been attached to a Camera?  Doesn't look like it...
Crystal Clear and Scratch-Free! 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. Perfectly matched threaded mountings on Super-Takumars make changing lenses quick and easy - even in the dark.

Infra-Red Index

Infra-Red Focus Mark 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 at 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.
