CAN ICES-3 (B) / NMB-3 (B)
zWhen using a lens that is heavier than the camera, be sure to hold the lens.
zWhen detaching the adapter, be sure to attach the front and rear cap to
protect the contacts. Make sure the adapter and cap mount indices are
aligned when attaching the caps.
zContacts that are scratched, soiled, or have fingerprints on them may result
in faulty connections or corrosion, which may lead to malfunctions. If the
contacts get soiled, clean them with a soft cloth.
zSince a lens’ minimum focusing distance is lengthened when this adapter is
attached, maximum magnification and field of view might change.
zThe rear mount on the adapter has been fitted with a rubber ring to improve
dust-resistance and water-resistance performance. This rubber ring may
cause friction marks to appear around the camera’s lens mount, although
this will have no effect on usage.
zRubber rings can be replaced at Canon Service Center (chargeable).
