frequently asked on DV forums and customer help-lines.
Questions from prospective buyers:
Is the Merlin more stable then the old JR? Why? How?
The JR was made with glass-filled plastic. The Merlin is machined
out of aluminum, brass and stainless steel which are much
more rigid, so it ‘conserves’ less vibrational
input from the operators hands. Merlins are also more precisely
fitted and mechanically tight and therefore require less attention
to stay ‘in trim’.
Why is it more expensive than a JR with monitor?
Precision-machined metal parts cost more than molded plastic
parts.
Can I fly my (HVX/DVX/FX1/etc..) camera on the
Merlin? It’s just over 5lb -- will it still work?
The official weight limit is 5 lbs (2.27kg), but we have
learned, for example, that the Sony ‘Z’ HDV
series and the Panasonic HVX200 (both above the limit) can
balance beautifully on Merlin with medium batteries and
no wide-angle adaptors; so, depending on the shape of the
‘payload’ (accessories mounted high up, for
example, make it harder to balance) you may slightly exceed
that limit.
If my camera plus accessories are overweight, what
options do I have? Can I add more counter weights?
We don’t approve of adding washers between the lower
weights in order to ‘fly’ more weight. Lightness
and rigidity are opposing requirements -- Merlin was engineered
to optimize both at its official maximum payload. Adding
additional counterweights may begin to strain the structure
and cause detectable ‘whipping.’ Try custom-mounting
accessories such as wireless microphone receivers and even
fill-lights down below the gimbal to solve this problem.
Watch for aftermarket accessory platforms that will replace
one or more of the supplied stainless weights.
How long can I use the Merlin before I get tired?
Do I need to start working out so I can carry it?
How heavy is your camcorder? Your full ‘payload’
will be 1.3 times that weight, including counterweights,
plus 13 ounces (.37 kg) for the Merlin itself. So, for example,
the lightest half-pound camcorders will total less than
1.5 lbs (.68 kg)! The heaviest cameras will require the
entire set of weights and the total will approach 8 lbs
(3.6 kg), and require much more work to lug around. For
heavier cameras, we suggest, at least initially, that you
design shorter shots! A two minute moving sequence is longer
than most theatrical Steadicam shots. Simply using your
Merlin will strengthen the relevant arm muscles over time
and within weeks your endurance ‘in the rig’
will greatly increase. We doubt you’ll need to ‘work
out.’ Check the instructional video for tips on sharing
the load with both hands.
Why do I need the Merlin if my camera has EIS (Electronic
Image Stabilization)?
EIS is meant to counteract the small angular vibrations
that are occur when you hold an object somewhere other than
at it’s exact center-of-gravity (which of course is
buried inside your camcorder!). With EIS, as soon as you
begin to walk or attempt to move your camcorder with your
arms, the size of the unwanted angular moves becomes way
too large for EIS to counteract and spoils the smoothness
of your shots.
In two important ways, Merlin beats the drawers off of 'Steadishot'
and other electronic image stabilizing features. The first
way is that Steadicam in general, (and Merlin in particular)
provides superior stability against both small and large
angular influences by shifting that famous “C.G”
from inside the camera body and placing it at the center
of a ‘gimbal’ that isolates the entire structure
against angular shakes.
In addition, Merlin turns your camcorder into a poised,
balanced, angularly inert object that can be oriented –
panned and tilted – with gentle finger pressure, and
moved energetically through space without angular influence.
In other words, Steadicam is inherently a more elegant,
smooth and precise way to hold a camera than is handheld.
Your camera can be poised as still as if on a tripod. Or
your entire range-of movement -- your full arm reach, bending-to-the-floor
and lifting-overhead, your the full freedom to walk and
run -- will be accessible to your lens without the ‘handheld’
bumps and shakes.
Of course expert Merlin shooting takes practice, but you
will take pride in your growing skills and eventually deliver
work that can be indistinguishable from Hollywood dolly-and-jib
shots!
So should you leave EIS active when using Merlin?
If the Gezornenplatz screw can extend to reach your camera
body or lens housing, you will be able to turn off EIS and
save on battery drain. Otherwise, at full telephoto, EIS
may provide additional vibration damping, but be aware that
some versions introduce hesitations at the beginning of
panning and tilting moves if the circuitry decides it’s
the beginning of a bump.
What is the difference between the Merlin and other
hand-held stabilizers?
Of course I’m biased, but the Merlin is by far the
lightest, and I think the most elegant and functional of
the lot. It has the best (patented) gimbal, the most precise
and accessible trim controls, and is by far the most stable.
Rotational inertia increases by the square of the distance
between the masses, and the Merlin has the greatest separation
between its counterweights. It also is the only hand-held
stabilizer that can be placed in perfect dynamic balance,
and the only one with our (patented) caliper hinge, that
always folds into the perfect storage position, regardless
of the adjusted size of the ‘arc.’ Oh, and did
I mention that the camera removes instantly and can be docked
on the supplied tripod-adaptor-plate.
Any chance for " Merlin Pro" to deal with
heavier cameres like the 24ps - the CanonXL2's and
XLHD?
Merlin was carefully engineered to be as light as possible
and still be stiff strong enough for 5+ lb cameras. Anything
much heavier would put the present gimbal and several other
components at risk. We are considering a slick,
ultralight arm/vest for Merlin and a all-metal ball bearing
gimbal which might edge up the limit to permit 6 lb cameras
but both of the Canons are heavier than that, even stripped
down, so they wouldn't qualify.
Questions from owners:
Why does the camera want to pan by itself when I walk around
and I'm only holding the handle?
The Merlin gimbal has ball bearings in the “pan”
axis and since it is an inert object, it tries to keep pointing
in the same direction, regardless of your moves. To control
the camera’s angle (as opposed to its position in
space), grasp the ‘guide ring’ with two fingers
and thumb, but very lightly, unless you need to alter the
angle of pan or tilt, and then use only the minimum force
required. (Remember that any move you start will require
equal force to stop, since the Merlin behaves like an object
floating in zero-gravity.
When I start moving, the camera tilts down and
when I stop it tilts up. How do I prevent this? (Is it related
to my horizon going off when I go around a corner?)
Good question. First understand that if the Merlin is neutrally
balanced at the gimbal what you describe would not happen.
However we have found that neutral balance has other hazards
-- it is way too touchy. If a mosquito landed on your lens,
it would tilt straight down! In practice, we employ an invaluable
compromise. We balance for slight bottom heaviness, which
allows Merlin to be trimmed to hang level (or at any angle
you choose). The downside is a slight tendency to be a pendulum
when you start, stop or go around a corner. You will learn
to counter this tendency with an equally slight, opposite
pressure from your fingers. If this tendency seems extreme,
your Merlin is too bottom-heavy. See the manual to check
‘drop-time’ and adjust it to be at least a full
second.
I can’t get it to balance with my camera,
where can I find good settings for my camera?
A settings table can be found at www.merlincookbook.com
If your camera isn’t listed, click on the link to
the ‘Magic Formula’ This provides a spreadsheet
that will calculate all your settings if you simply enter
two numbers: your camera’s exact weight and the vertical
c.g. distance.
What is the “vertical CG” referred
to in the Setting table?
See the instructions that accompany the ‘Magic Formula’
spreadsheet link. Even if your camera does not yet appear
among the published ‘Settings’ table, if you
know its final shooting weight (with tape, etc.) and its
‘vertical CG distance’ you can easily obtain
your complete settings. The ‘vertical CG distance’
can be found by experimentally balancing a flat side of
your camcorder (or the lens cover or the battery) on your
finger and marking that point with a grease pencil. Then
measure the distance from that mark down to the base of
your camcorder. What you have determined is the location,
within your camcorder, of that famous CG point, and additionally
how high up from the camera mounting surface that is. If
you enter those two numbers – weight and vert. CG
– in the marked boxes
How can I mount a wireless microphone receiver
to my camera (or the Merlin)
See Jim Farrell's ingenious aftermarket accessory shelf
at: www.jimfarrell.com/merlin
How do I zoom/focus/adjust camera settings while
flying? How do I start and stop recording?
For now, various stand-alone zoom/focus/pause controls are
available on the market. Panasonic made (and discontinued)
a particularly small and light version which, if you can
find one on e-bay, can be velcro’d to the Merlin handle.
If you master one-handed operation, you can also control
these functions with the other hand by means of the infrared
remotes supplied with many camcorders. Watch this FAQ and
the Steadicam.com Merlin pages for notice of future LANC-type
controllers compatible with Merlin
I have a wired zoom/focus controller, but when
I use it with the Merlin it throws off the balance. What
can I do?
It is important that the path of the wire, either curly-cord
or straight, be arranged to minimally influence balance.
We suggest that the cord should pass up along the side of
the camera just above the Merlin gimbal (flex-tie it to
the camera’s side handle, for example), so it has
the shortest possible ‘lever-arm’ to influence
pan/tilt. Of course the thinner and more flexible the wire,
the more satisfactory the results.
Is it possible to set the Merlin to hang at some
other angle than level - to trim tilt for a specific shot?
(Aha! You must be an American -- you didn’t look at
the DVD or read the manual!) Yes. The blue roller on the
side of the stage adjusts the nominal hanging angle of the
Merlin. Pushing up on the roller causes an up-tilt. Pulling
down causes a down-tilt. Experiment. And by the way, the
blue roller under the stage controls the side-to-side angle,
AKA ‘roll.’ (If you don’t know what the
stage is, you may actually have to read the instructions!)
I’d like to shoot looking up or down at something,
is there a way I can set the camera to be tilted way up
or down?
The Merlin can be trimmed to tilt radically up or down (push
up the blue fore/aft trim roller to balance tilted up),
but we would only recommend it if your entire shot was to
be at that angle – otherwise you would have to ‘fight’
that trim the rest of the time. If a single shot has both
high and/or low angles and at times needs to be level, try
reducing bottom-heaviness so the Merlin is more neutrally
balanced (see the video or manual – counter-clock
the ‘Z’ ring 3 or 4 turns so the ‘drop
time’ is up to 3 seconds) – and it will require
almost no effort for your fingers to hold those extreme
tilts. (Keep in mind that more neutral trim will make subsequent
normal operating a bit more touchy and harder to keep level,
so remember to return to slight bottom-heaviness for subsequent
shots)
I got it all balanced, then I put in the tape and
opened up the LCD, but now it’s all wrong. Why?
I mean no disrespect whatsoever, but ‘Duh’!
You changed the distribution of mass! You moved weights
sideways! C’mon! I know people aren’t used to
balancing things in the 21st century, but, as we say in
Philly, ‘Yo!’
Why won’t my Panasonic DVC-30 want to hang
upside down? I used the Cookbook settings!
I take back the above abusive remark. This was my error.
I provided our web designer the wrong setting for the lower
weights. I apologize to all DVC-30 owners. It has been corrected!
Why doesn't Merlin have a monitor? My operating
is limited if I can only use the cameras monitor.
Using the camcorder’s monitor is indeed somewhat limiting
and requires contortions to view-find at certain angles.
We will eventually offer a slick, lightweight monitor to
screw on in place of the front weight.
Do I have to use two hands? (Or: I can’t
operate one-handed!)
Two-handed operation is generally easier to control and
is thus more precise. One-handed operating requires more
practice. Watch the DVD closely to see the exact hand position.
Keep the gimbal handle a bit sideways so that the part of
your first finger between the first and second joint lightly
contacts the front tongue part of the gimbal, and your thumb
lightly contacts the rear surface of the gimbal. Open and
close your finger & thumb for intermittent contact with
the gimbal if the angle of the shot needs changing. When
you start a pan, make your whole hand turn a bit, so your
fingers are never strained or contorted. If your grip is
uncomfortable then it is incorrect. Closely watch the sections
of the DVD that describe one-handed operating.
Can I mount the Merlin or my camera to a tripod
quickly, or do I need to buy a quick release plate?
Every Merlin comes with a tripod adaptor plate. The dovetail
mounting plate, plus camera, instantly unlocks from the
Merlin and locks onto the tripod adaptor plate. Note the
Merlin ‘stage mark’ beforehand so you can remount
your camera back in the balanced position with a minimum
of re-trimming
What's a dovetail?
On full-sized Steadicams the dovetails are the thick camera
mounting plates with beveled edges. On your Merlin it’s
the blue & black sheet-aluminum sandwich with the 15
camera-mounting holes and the locking lever.
What is the “Gezornenplatz screw”? (Garrett,
where the heck did this name come from?)
I thought I made up the word, but remembered that it was
the punchline of a Bob Newhart sketch. An “infinite
number of monkeys with typewriters” would eventually,
randomly write Shakespeare’s works, but also lots
of dreck like: “To be, or not to be, that is the Gezornenplatz.”
In Merlin terms, the flimsy mounting structures on many
camcorders may cause visible vibration: Counterclock the
supplied plastic bolt upward until it kisses the underside
of your lens housing, and you’ll be able to work at
much longer focal lengths (now that is the Gezornenplatz!”)
The gezornenplatz screw doesn't seem to contact
properly on my Sony HDR-FX1. Any tips? Have
you heard this from other fx1 owners?
The head of the 'gezornenplatz' screw is narrow. We used
it because it's lightweight and won't mar camera surfaces.
You can slide the dovetail plate forward or rearward before
you lock it down which may help this issue. Then adjust
the fore/aft trim roller to get back in balance. The consequence
for dynamic balance will probably be slight.
If that doesn't do the trick, You can replace the supplied
'gezornenplatz' with any so-c1/4-20 screw or bolt (quarter
inch diateter, 20 threads per inch). So, if the gezornenplatz
is too short, or too narrow at the top, you can acquire
a longer screw or wider version at any hardware store. We
suggest you put some tape on the top so it won't scratch
your camera.
I Just bought a "Steadistand" but can't
figure out what it has to do with the Merlin. It did not
come with any manual or pictures, so I was just wondering
if you could clue me in on the proper use of the Steadistand?
The Steadistand is not the little plastic item that used
to come with the Steadicam JR. It's larger and heavier,
with a base plate and jointed arms and a u-shaped yoke.
Adjust the arms and lock the joints with the supplied allen
wrench so the yoke is poised horizontally above the baseplate.
Now you can set the Merlin gimbal within the yoke (with
the handle dangling) and it will be safely 'docked'.
If you are working within a location and can keep the Steadistand
nearby on a table, it provides a safe place to quickly set
down Merlin and camera between setups, shots or even indivitual
takes if your camera is heavy. An additional benefit is
that your 'trim' settings will be exactly preserved.
Are there instructions on the proper use of the Steadistand
and docking bracket? I have both items and can't figure
out how to put it all together and safely have my Merlin
and camera docked.
The Docking Bracket clamps onto a light stand (the kind
with a 5/8th inch stud on top). the Merlin handle is lowered
gently onto the upright pin, and is 'docked' safely so
you can walk away.
The Steadistand is a bit more complicated. Loosen the joints
and arrange them in an arc so the 'yoke' part is horizontal
and roughly over the stand base... then lock the joints
tightly. The merlin gimbal can be set down within the arms
of the yoke, and docks with the handle dangling. The former
is for floor use. The latter sits on a tabletop.
The mounting screw loosens when placing the the camera
- mounted on the Merlin - on my knees while sitting in
a driving car (on bumpy road). What should I do?
Did you put two parallel strips of cloth 'gaffers' tape
on the base of your camera riunning fore and aft at either
side of the mounting hole? We designed the mounting screw
to have the maximum threads to grip the camera. If,
on some cameras, the screw is nearly 'bottomed out' you
will need these tape strips. They will compress slightly
when the screw is tightened and keep it under pressure,
as well as making the mounting a bit more firm. (If you
already have such tapes, as per the manual and DVD, add
another thickness).
The Velcro patch on the Grip loses stickeness to the matching
Velcro under the bubble level after short time of use.
If the velcro has worn out already I would be surprised.
However, if you can find thin black self-adhesive velcro
strips -- In the US, for example, at 'radio shack' -- stick
a short male and female strip together (adhesive to adhesive)
and then use the female side to contact the stage. This
will have the effect of making the velcro protrude further
and the 'male' side will give you additional contact with
the 'female' velcro on the handle.
