Example
• Using a Compact Prime CP.2 35mm/T2.1 lens with an EF mount, scaled in feet and
a test chart at a test distance of 4 ft, an actual distance of 4 ft 1’ is measured. Due
to the table on page 14, a silver shim 0.013 mm must therefore be added to the total
thickness of the shims.
Note
• Any combination of shims is possible to achieve the required thickness and
therefore the desired flange focal distance.
• Always use the closest possible combination of shims.

Tables for adjusting the flange focal distance
of Compact Prime CP.2 lenses
All Compact Prime CP.2 lenses cover the full-frame image format (24 x 36 mm),
ANSI Super 35 and Normal 35 image format, except the CP.2 18mm/T3.6. This lens
covers the ANSI Super 35 and Normal 35 image format.
Key
• Minus sign: Shims must be removed
• Plus sign: Shims must be added
