curve to prevent blown-out highlights and
overexposure, an ISO 100-102,400 range
of sensitivity, in-camera ND filter, and
support of the ACES proxy.
Canon has also announced the
second generation to its lowest-cost fullframe DSLR model, the EOS 6D Mark II, as
well as an update to the popular consumer
family of interchangeable-lens APS-Csensor Rebel cameras, the EOS Rebel SL2.
Priced as gateway models to the world of
interchangeable lenses, both cameras are
capable of a maximum video resolution of
full HD at 60p with MPEG-4 AVC H.264
compression.
The original EOS 6D offered a maximum resolution of 1920x1080 at up to 30
fps; the EOS 6D Mark II doubles that rate to
60 fps and offers an internal HDR-capture
mode. Internal time-lapse is also available in
up to 4K on the 6D Mark II and HD on the
Rebel SL2. Both models have an articulating
3.0" Vari-angle Touch Screen, as well as the
Dual Pixel CMOS AF autofocus tracking
system. There are several boosts to the EOS
6D Mark II's stills capabilities, including a
maximum 6.5 fps burst rate, up from 4.5
fps; 45 all-cross-type autofocus points over
the previous offering of 11; and a native
ISO range of 100-40,000, up slightly from
100-25,600, with expandable ISO available
up to 102,400.

Arri Extends Matte-Box Range
Fitting standard 4"x5.65" and
4"x4" filter sizes, the Arri LMB 4x5 matte
box builds on Arri's line of lightweight
matte boxes to offer a highly configurable
filtration and flare-suppression system.

Available in a variety of 15mm and
19mm or clampdown kits, the LMB 4x5
is available in a number of configurations, beginning with the Basic Module
and culminating in the LMB Pro Set.
The LMB Pro Set comes with every
available item in the LMB 4x5 matte-box
system except for 15mm and 19mm
studio rod adapters. The LMB 4x5
screw-in 15mm LWS Console attaches
Arri's 15mm lightweight LWS 15mm
rods, and the bundle also has a top-orbottom-mountable LMB 3 ⁄ 8 " accessory
adapter for ultrasonic distance measurement devices. There are three extendable
carbon-fiber flags, one for the top or
bottom, and two for the sides.
A rubber-donut-style tilt-and-flex
adapter will affix to front lens diameters of
62-143mm, while the tilt module also has a
+/-10-degree arc with horizontal adjustments to align and compensate for
unwanted reflections, flare suppressions, or
filter effects. The tilt module is swing-away
for fast lens swaps and filter changes. The
LMB 4x5 Basic Module can also be
converted for 15mm or 19mm rod support
with a 143mm top-or-bottom clamp
adapter, or to clip-on mode through available clipping adapters.
Adding the LMB 4x5 Extra Rotatable
Filter Stage - a third filter stage with integrated tray catcher and 360 degrees of
travel - to the LMB 4x5 Basic Module
allows time-saving quick-mount filter rotations and removal or lens swaps. The basic
LMB 4x5 Extra Non-Rotatable filter stage is
compatible with all current Arri R2 filter
rings, and can be used on its own with the
15mm LWS Console as the most lightweight setup possible. Both the LMB 4x5
Extra Rotatable filter stage and the LMB 4x5
Extra Non-Rotatable filter stage can be used
as standalone filter stages when used with
LMB 4x5 clamp adapters. The LMB 4x5
Basic Module can also be extended by
adding a clamp adapter.
Arri is offering the LMB 4x5 as an
attractive option for LMB-25 owners, with
upgrade pricing available through the
company. If the full LMB 4x5 Pro Set is
purchased, the kit also comes with two
LMB 4x5 Flag Holders and two sets of five
mattes - one anamorphic and one spherical - all of which is compatible with the
113
