Unique Lens Operation
Supplied Wide-angle Fujinon 14x Zoom Lens
Both camcorders are equipped with a high-quality, high-
definition Fujinon 14x zoom lens specifically designed to
offer optimum picture performance and unprecedented
functionality.
The lens offers a wide viewing angle of 5.8 mm (equivalent
to 31.4 mm on a 35-mm lens), and many convenient
features for diverse shooting situations.
Unique Focus Ring Mechanism -
Professional Manual Focus and Auto Focus
The lens adopts a unique focus ring mechanism, which
offers two types of manual focus, plus auto focus
operation. The lens is equipped with two independent
focus wheel mechanisms, which can be switched by
sliding the focus ring forward and back.
When the focus ring is in the forward position, the lens works
as an auto focus lens. Either Manual or Auto Focus mode
can be selected using the AF/MF switch on the lens. When
the focus ring is set to the back position, the lens has an
absolute focus position.
In addition to the focus ring, the lens is equipped with
independent rings for zoom and iris adjustment; all have
physical stops and absolute markings, permitting precise
adjustments. The location, rotational range, and feel are
identical to other manual high-end HD lenses. This gives
users a high level of familiarity and operational comfort.

AF Assist
The AF (Auto Focus) Assist function of the PMW-EX1R and
PMW-EX3 enables operators to manually change focus
positions using the focus ring in AF mode. This means that
AF reference focus positions can be shifted manually to a
new position.

MF Assist
The MF (Manual Focus) Assist function of the PMW-EX1R
and PMW-EX3 helps to precisely focus on the target
subject when shooting in MF mode. When MF Assist is
enabled, auto focus is momentarily activated when the
user stops adjusting the focus ring. The camera then finely
focuses on the subject that is closest to the focal point of
the lens at that time.
One-push Auto Iris
(PMW-EX1R Only)
A One-push Auto Iris button has been
added to the lens of the PMW-EX1R,
allowing the user to go into Auto Iris
mode only when this button is pushed.
Interchangeable Lens System (PMW-EX3 Only)
The PMW-EX3 camcorder incorporates a 1/2-inch-type
EX-mount interchangeable lens system that allows the
lens to be as compact and lightweight as possible while
maintaining high optical performance. This mount system
supports a variety of 1/2-inch-type HD lenses available
from major manufacturers with the PMW-EX3 camcorder
via the supplied lens adaptor, expanding the spectrum of
creative expression.*
A 2/3-inch-type lens** can also be used with the
PMW-EX3 camcorder via the mount system; this requires
a 2/3-inch-type lens adaptor*** equipped with a 12-pin
lens connector. This illustrates the range of lens choice,
including cinema-style lenses, to suit every specific
shooting requirement.
*The 1/2-inch-type lens adaptor supplied with the PMW-EX3 camcorder
is equipped with a hot-shoe lens mount connector only. Automatic lens
iris control is achieved only if the lens has hot-shoe connectors. Some
lens functions are not supported by the PMW-EX3. For more details,
please contact each lens manufacturer.
**In this configuration, the resulting focal length will be 1.37 times the
actual focal length of the lens.
***When using 2/3-inch-type lenses with the PMW-EX3 camcorder, a
Fujinon ACM-21 or Canon LCV-41E lens mount adaptor is required.
