Spectra Pro/Image Pro/Minolta Pro Performance Differences
Several features to improve exposure accuracy and picture sharpness have been incor-
porated in the Spectra Pro/Image Pro/Minolta Pro design. These include the following:
• Improved lens
Spectra Pro/Image Pro/Minolta Pro cameras have color corrected, coated, f/10,
125mm triplet glass lenses.
• Intentional ambient overexposure to brighten scene
For light levels greater than 624 cd/ft2, a limited exposure kickup occurs to produce
a bright picture (truer whites, better facial exposure) without sacrificing detail.
• Double measurement of ambient brightness
Camera electronics remeasure the scene brightness when the second stage of the
shutter button is closed. This ensures that the latest data is used in the exposure
calculation, preventing errors caused by previewing one scene then shooting another
without releasing the S1 button.
• Intermediate fill flash mode
This additional strobe exposure program mode allows mixing a 50% flash contribution
with a 50% ambient contribution for light levels between 8 and 24 cd/ft2. This
brightens the backgrounds of low-light pictures and increases the shadow fill at
higher levels.
• Bias focus
When available depth of field permits, the Spectra Pro intentionally focuses one or
two zones behind the subject, improving overall scene sharpness.
