EOS
DCS 3 Lenses: Lenses behave differently with the EOS
DCS 3
from a conventional EOS 35mm SLR. Although actual aperture values
and focal lengths remain the same, the effective image area with the
EOS
DCS 3 is only 16.4 mm x 20.5 mm compared to the conven-
tional 35 mm format of 24 mm x 36 mm.
Since the EOS
DCS 3 image is smaller than a conventional 35 mm
frame, it must be enlarged by approximately 50% to achieve the same
output size (in terms of image height) on screen or on hard copy.
Under this condition, the “effective” focal length of any lens used with
the EOS
DCS 3 is approximately 1.5 times greater than when used
with a conventional EOS 35 mm SLR. Use the following chart as a
quick reference for effective focal lengths of EF lenses when used with
the EOS
DCS 3.
NOTE: The EOS
DCS 3 is compatible with all Canon EF lenses (no restrictions).
This EF lens . . .
. . . performs approximately like this lens.
