a close look at Sony's XD CAM EX1
solid-state camera
courtesy B&H Photo Video
This review is based on a
three-day test shoot conducted at CCNY (City
College New York), where I teach in the
Media & Communication Arts department's Film
and Video Program. Thomas Cznarty, a
graduate cinematography major and an
experienced camera operator, assisted me.
Kymberli McKenna, an actor, kindly acted as
our model. The interior portion of the shoot
was done in a studio under tungsten
lighting, and in some various interior
locations in available lighting. We also
took the camera outside and shot on
Amsterdam Ave at 138th street in New York
City during the afternoon and the "magic"
hour. We then transferred the media into
Apple's Final Cut Pro and got a first
impression of the work flow.

I was initially drawn to
the
Sony PMW-EX1 early last fall after
reading about the specs, a native 3 1/2"
1920x1080 CMOS, 24P, non-shoulder mount,
solid-state camera. I like the versatility
of a handy-cam, so I never really considered
a 2/3" shoulder mount. I need a camera that
doesn't draw attention to itself, that is
rugged, and that can be handheld easily.
This is mainly because of my work with UNTV
(United Nations TV). We travel to remote
countries where conditions are often
difficult and the weather is uncooperative.
I need to be able to carry my own gear
(video and audio) and remain as
"transparent" in situations as possible. But
I need to bring home visually compelling
material. You could say that I like to have
my cake and eat it, too. Don't we all? Well,
the EX1 might be as close as you get to do
that, at least for the time being.
THE BODY
I'll start from the body
of the camera, as it appears when you open
the shipping box. The first thing one
notices is the weight, 6 pounds, 2 ounces
with lens hood, the standard PB-U30 battery,
and one SxS card. It is almost twice the
weight of the Panasonic DVX 100, and about a
pound heavier than the Sony Z1U. I don't see
this as a problem personally, as it allows
for steadier handheld shots. I find the DVX
100 and even the Z1U too light for that
particular function. Gravity needs to anchor
a camera so that handheld shots are
naturally steady. If the camera is too
light, the shots end up jittery and convey a
threat of motion sickness-a feeling we all
know well. If you replace the standard
battery with the optional PB-U60-which you
will want to do because it allows for 4
hours of use instead of the 2 hours of the
standard battery-you add another few ounces,
but that extra weight, concentrated on the
back end where the battery fits horizontally
balances the camera nicely, as it tends to
be nose-heavy.
THE LENS
Sony has separated (at
least for this camera) from Carl Zeiss and
has teamed with Fujinon-known for its
remarkable professional broadcast lenses in
SD and HD for 2/3" camcorders. It is a
non-interchangeable lens, just like the Z1,
the DVX 100, and HVX 200, but what a lens it
is. It is heavy, and does put some strain on
the wrist while handholding the camera, but
it is well worth the price for the quality
it delivers. It's a 14x zoom lens, which has
a 5.8-81.2mm range, and a luminous F 1.9
aperture. At its widest (5.8mm) it's
equivalent to a 31.4mm on a 35 reflex
camera, and slightly wider than the HVX 200
and DVX 100. At full telephoto mode (81.2mm)
it does compress the perspective very
nicely, and you get a real taste of the
shallow depth of field, enhanced by the 1/2"
CMOS sensors. I don't foresee a great need
for a wide-angle or a telephoto adapter-at
least not for everyday, common use (Sony
offers a .8X wide conversion lens). Unlike
the other handy-cam camcorders currently on
the market, the lens on the EX1 has a proper
f-stop-marked aperture ring, just like a pro
lens. The zoom lever has clear millimeter
markings, 5.8 to 81.2, and a removable
screw-in lever.
The focus barrel is what
really differentiates this lens from its
direct competitors. Anyone who has worked
with any of the previously mentioned
camcorders knows that serious focusing
cannot be accomplished with
servomotor-designed autofocus lenses, even
when they are set on manual. On those lenses
the barrel is unmarked and spins forever,
and when pulling focus, the barrel itself
feels like it spins more than it rotates,
because it offers no resistance. The EX1
does have the servomotor system, which
allows for the AF mode and push-button AF on
MF mode. But by physically gripping the ring
and pulling it towards the body of the
camcorder (about 1/2"), the lens is
transformed into a Full Manual focus lens.
It now stops at infinity and at the macro
end. It has foot and meter readings, and
when you pull focus it becomes stiff enough
for you to feel what you are doing. No more
focus blowouts because of wind (it happened
to me one too many times with the DVX
100-and it's embarrassing and difficult to
explain when you are watching the footage
with your producer, or yet worst when you
get a call from the editor). The lens also
appears to have an adequate built-in optical
stabilizer.
As mentioned earlier,
this lens does add considerable weight to
the front of the camera. To compensate for
this potential problem, Sony has cleverly
designed an interesting solution to help
avoid excessive wrist strain.
ROTATING HANDGRIP
The handgrip rotates in
click-stops, and is easy to regulate on the
fly, appearing to be rugged and effective.
It can be rotated a full 100 degrees, which
allows you to maintain a natural wrist
position while handholding the camera at
different heights (from overhead to
knee-level). I have not seen this insightful
addition in other camcorders. The only
drawback is that the handgrip itself
protrudes excessively, throwing the camera
off-balance to the left, thus making it
virtually impossible to hold with a single
(right) hand. You will always need to
support the camera with your left hand under
the body.
EYECUP, VIEWFINDER, AND LCD SCREEN
A small detail that
puzzled me right away was the eyecup. I use
my left eye when operating with the
viewfinder. Unlike the eyecup on the V1U, I
was surprised that the eyecup can't be
removed and switched around to accommodate
"left-eye" operators like me. This is
because the eyepiece focusing knob is
covered by the eyecup when the eyecup is
flipped and positioned for the left eye. The
eyecup was just not designed to be flipped.
I guess I will have to purchase a special
'lefty' eyecup from Sony, hoping that they
manufacture it. Because of this, I shot the
tests relying solely on the flip-out LCD
monitor, which has a 640X480 resolution. It
is an all-new transmissive-reflexive hybrid
LCD (works backlit or by reflection in
bright sunlight). Its forward placement is
ideal both for handheld and tripod
operation, and the LCD is reliable for
focusing, especially when using the 2X
expanded focus function (which maintains a
1:1 pixel display). A well-positioned button
on the handgrip controls the expanded focus
function.
ON/OFF SWITCH, BUTTONS, AND CONTROLS
The On/Off switch for the EX1 has 3
positions: Camera-Off-Media. Seemingly
ill-conceived, the switch itself is very
small and recessed. It is also quite stiff
with a very short space between the 3
functions. It's easy to switch the camera
off mistakenly instead of setting it to
Media, and vice versa. This brings me to a
general note about the EX1: almost all of
the knobs, buttons, and the jog dial on the
body of the camera are too small. They are
difficult to feel at the tip of your
fingers. Because they are mostly used on the
fly, and a camera operator frequently needs
to change settings quickly without removing
the eye from the LCD or viewfinder, this is
an unfortunate drawback.
SxS MEMORY CARD
Inserting the SxS memory
card is easy and fast, and with its two
slots, the camera is theoretically able to
record continuously and endlessly (by
switching automatically and seamlessly from
slot A to slot B and vice versa).
Pressing REC coincides
with the moment you begin to appreciate one
of the advantages of memory cards versus
tape-recording systems. Solid-state
recording means that the moment you press
REC you begin to lay video (and audio) data.
There is no lag time required as the tape is
being shifted onto the heads. There are no
more linear parts to the process, the
digital dimension is embraced in full, and
it is quite an invigorating experience. For
me, it had begun to seem increasingly
anachronistic and contradictory to have to
insert a tape into a digital camcorder, a
system that felt antiquated, like a leftover
from a time that had long passed. With the
EX1 I will not miss cassettes, dirty heads,
tape dropouts, lag time when pressing REC
and STOP, and log and capture tedious and
time-consuming process to prepare the media
for post-production random access. The EX1
is an all non-linear, international and
universal camera: It records in all flavors
of HD. The scanning mode is switchable among
1920x1080, 1280x720, and 1440x1080
resolutions. Frame rates go from 60i, 30P,
50i, 25P, and native 24P. In addition, 60P
and 50P are available in 1280x720 mode.
These formats can be output in HD or SD,
making them compatible with NTSC and PAL
regions. The EX1 has 2 slots for 2 cards,
currently available in 8GB and 16GB, with a
32GB card announced for 2008. On a single
16GB card you can record 50 minutes of full
HQ (35mb/s) HD footage. These recording
times mean that you won't have to drag a
computer and hard drive to the field to
start archiving and backing up as you shoot.
IMAGE QUALITY
We shot our tests mostly
at 1080/24P, at the HQ setting of 35mb/s. We
chose a shutter speed of 1/48. Both Thomas
and I come from a film background, and I
guess we wanted to see how the camera
performed using a film-like setting. Thomas
took a light reading with his Spectra Cine
Pro IV-A: The EX1 sensitivity translates to
a film equivalent of ISO 500.
While I was setting the
camera, Thomas prepared a basic 3 light
set-up (Key, Fill, and Backlight) I am very
impressed by the softness of the image on
Kymberli's face; something I was not
expecting from a Sony camcorder,
traditionally known for sharpness and
contrast. The colors have a wonderful punch
without being overly saturated.
These images are not
color-corrected, and were obtained with the
EX1's standard picture setting. The only
adjustment made was an offset of 200 K
(warmer) on the white balance. The EX1 has 6
pre-set Picture Profiles, which enable you
to store to memory 6 different picture
settings. With an HD field monitor, I could
see getting into elaborate selections of the
many available settings: hue, saturation,
phase, specific frame area of color phase,
detail level, frequency, white/black
limiter, skin tone details, gamma curve,
knee point, etc.
We tried the EX Slow
Shutter, an advanced mode of the SLS (Slow
Shutter Speed). We wrapped the ever-patient
Kymberli in X-mas lights, and I zoomed in
while shooting at a 16-frame accumulation.
An even more dramatic streaking light effect
could be obtained by setting it to 32- or
64-frame (maximum) accumulation. In the next
image, also at 16-frame accumulation, I
panned and tilted circularly, with the
camera on Thomas's 501 Manfrotto/Bogen
tripod.
Under-cranking (sped-up)
and over-cranking (slow-mo) capability is
another feature that makes this camera
arguably the most flexible on the market (in
its category). The frame rate depends on the
shooting format. At 720 shooting modes,
because of the lower bandwidth requirements,
the camera will shoot at up to 60 fps.
We tried it, shooting 60P
at 720, with me following Kymberli going up
a staircase and walking down a hallway.
Played back at regular speed, it does create
an impressive film-like slow-mo, quite
different from the result you get by
shooting at 30P (or 24P) and subsequently
selecting a 50% speed setting in FCP.
MACRO
 |
To make use of the macro
capabilities of the Fujinon lens,
one needs to set it to MF (not Full
Manual Focus) by gripping the ring
and pulling it away from the body of
the camcorder. One can then either
pull focus manually, use the PUSH AF
button, or set it on AF. The macro
will not work in Full Manual Focus
mode. |
In macro mode, one can
appreciate the contrast between the softness
of the background and the impressive detail
of the area in focus. Here the HD reads
almost too much information — highlighting
blemishes, minuscule blackheads, and other
skin and makeup imperfections.
We wanted to see how the
camera fared in highlights. We exposed for
Kymberli's face and we let the parts in
direct sunlight blow out. Except in the full
blown-out sections of the image, there is
still considerable information in areas that
are 5 stops overexposed. I was looking out
for purple or green fringing on the vertical
line of the dark door against the
overexposed background, but I was happy to
see that there was virtually none. I have
shot in similar conditions with the Z1 and
must report that fringing had been an issue.
EX1 (left) V1 (right)
We did a comparative test
in low light between the EX1 and the V1 (I
would have preferred to do this same test
with the Sony Z1, the JVC GY-HD200CHU or the
Panasonic XVX 200, but those cameras were
not available that day).
Both the EX1 and the V1
had the iris wide open, the EX1 at F 1.9,
the V1 at F 1.6, shutter speed on both at
1/48, both with gain at 0 DB. There is close
to a 2-stop sensitivity difference between
the 2 cameras, and the EX1 reads remarkably
well in the underexposed areas. One can also
notice that the angle of view of the V1 is
not as wide as the EX1's.
We went outside during
two afternoons on clear winter days. We shot
at sunset and "magic" hour.
Here Kymberli is on
Amsterdam and 138th St., facing south, at
magic hour. We are not using any reflector
or bounce card, yet she seemed to literally
glow in the falling light. I was very
impressed by the softness of the contrast on
her face and the wonderful shallow depth of
field.
We shot in HQ, 1920x1080
native 24P, and played back the footage via
the component output on a 22" HD display.
The image quality is superb, and the way the
color was pulled out even after the sun had
set and the light became flat was
outstanding. The primary colors, especially
the greens, the yellows, and the reds become
electric and give a richness to the image
that is quite sensational, and I could
already sense that on the flip-out monitor
while I was recording.

In the above
shot, one can appreciate the quality
of the lens for its sharpness, and
shallow depth of field. |
 |
|
In this wide
shot, with the light way past magic
hour, the details still read in the
underexposed areas, and the colors
have a sparkly punch. |
LOW LIGHT:
At 9DB gain, the
noise/grain becomes noticeable but still
very acceptable. We did not shoot at 12 or
18DB gain, but from looking at the LCD, it
appeared that noise was becoming a factor at
those settings. The EX1 has native 1/2" HD
1920x1080 CMOS chips: All these tiny pixels
create the sharpness of the image but they
absorb less light than a standard definition
720x576 CCD. So Panasonic's in-camera
pixel-shifting technology (which "forces"
1280x720 HD resolution from CCD's that don't
physically have all those pixels) will allow
for greater sensitivity in low light (of
approx. 1 stop) at the cost of a slightly
lower resolution. It's a trade-off, and
choosing between these two cameras depends
upon the conditions in which one uses the
camera most often.
ONTO FINAL CUT PRO:
Minimum requirements are:
Mac OS v.10.4.11, QuickTime Pro v.7.3, FCP
v.6.0.2, and
Sony XDCAM Transfer Tool (PDZK-P1 XDCAM
Transfer V 2.1) which you can download for
free.
The procedure to import
the media onto Final Cut Pro was
straightforward. There is more than one way
to do it. I ejected the SxS card from the
camera and slid it into the Express 34 side
slot of my 2.4 GHz Intel Core 2 Duo MacBook
Pro. I then opened a project in FCP with the
settings XDCAM EX 1080 24P 35 VBR (that's
the way most of the shots were recorded),
then I went to the File menu and selected
Import > Sony XDCAM. At that point, the Sony
Clip Browser appears and one can highlight
each or all clips and choose Import on the
lower right side of the Clip Browser window.
Before transferring the clips I made sure to
assign the desired destination for the
actual video clips to be stored, because
Sony's browser default location is the
Documents Folder of the start up drive. The
media transferred very quickly — 4 minutes
for 40 minutes! (It would have been
approximately three times slower had I
connected the camera via USB).
For some reason, some of
the transferred clips showed up twice in the
FCP browser. I found out that other users
have experienced the same problem. To solve
it, I deleted the clip names from the FCP
browser, then opened the folder in the hard
drive, copied the names of the clips and
pasted them back onto FCP's browser. That
took care of the glitch and there was no
need to re-transfer any clips. Hopefully,
this issue will be addressed and solved in
Sony's Transfer Tool software update.
CONCLUSION:
With the
EX1, Sony has created a handy-cam that
is in a league of its own. It has set a new
standard for solid state, low-cost,
fully-professional cameras. In size and
appearance the EX1 looks like a Z1 or an
HVH200, but it delivers far superior image
quality. For car aficionados, it would be
the equivalent of the engine of a
12-cylinder GT Ferrari in the body a Lexus.
I am a happy EX1 owner and will gladly start
dealing with the archiving issues of
solid-state recording (which would merit a
whole separate article) and leave behind —
forever — videotape, which has been the
anachronistic glitch of the digital
workflow. My only reservations have to do
with body design, more appropriate buttons
and controls, and some menu shortcomings
(which I have not gotten into in this
article for lack of space).
