AF 200mm f/4 Macro Apo G (Lens aperture range: f/4 - f/32)
• The tables beginning at the bottom of this page shows values when
ISO 100 film is used without the wide-angle adapter or diffuser. For
other ISO film speeds, or if you use the wide-angle adapter or diffuser,
adjust the aperture settings according to the tables on page 32.
• The aperture ranges given in the tables are calculated values; the
actual lens will have its own usable aperture range.
Example: Using an AF 50mm f/2.8 Macro lens with a pair of twin flash
units with no arm, at a magnification ratio of 1:1. The range of accept-
able apertures is calculated to be from f/4 to f/90 (bold type in the
table). However, the actual range possible with this lens is f/4 to f/32.
• The following tables show data for certain lenses and magnification
ratios. For other lenses and magnification ratios, see pages 60 and
62.
