*1: The lens cannot be used with a filter, since focusing is interrupted by an
attached filter touching the front of the lens. Also, filter may be damaged or the
lens malfunction may result.
*2: Attach a filter to the front of the lens before attaching Macrolite Adapter (p.21) to
the front part of the filter. If attachment threads are not provided on the front rim
of the filter, the flash unit cannot be attached since Macrolite Adapter cannot be
attached. Note that if the flash unit is attached after a filter and Macrolite
Adapter are attached to the front of the lens, the periphery of the photo may
look darker.
*3: Attach the Lens Hood ES-27 to the front of the lens before attaching a 49 mm
filter.
A commercially-available filter can be
used during flash photography. A filter
can be attached, using the two
procedures described below. Filters may
not be used together with some macro
lenses.
