Element Technica has just released a new optional part for the Atom rig.
href="http://www.technica3d.com
Also posted on my blog.... steadi3d.com
It allows you on a crane or jib to slide the rig further back and this reduces the amount of counterweight needed since it moves the CG closer to the mounting point.
Here is a side by side comparison of the "standard" sharkfin and the new"steadi/jib" sharkfin.
As you might see below what they did was remove a significant amount of material to allow this movement. Now admittedly there might be a slight reduction in stiffness but this is only intended for use on a steadicam or jib/crane. So this is less of a concern. The benefits here outweigh the cons.
You see them here bolted on the Atom rig. On one side I mounted the standard and on the other the new one. You can clearly see the difference in this picture.

Yea Nick I agree on the Rates having to be raised. Come on guys these rigs are stupid to destroy your body. They are heavy heavy rigs. We need to charge more for productions wanting us to fly these beasts! I've done a bit of 3D work and it is way more strenuous on your body and your gear.
Absolutely, hold onto your higher rates. I do.
Recently got a call and turned it down, producer said he had a local op. (canada) that would do it for less (way less) I told him good luck.
No thanks.

Thought it might be interesting to some of you guys....
I launched my new Blog/site today. I put up over 60 articles already! (many of them with picture galleries)
www.steadi3d.com
Going to chronicle some of the work I do, gear reviews, instructional information, video tutorials etc.....2D and 3D stuff.
I'll update it frequently....
Hope u guys like it....

I made a 3D steadicam post.....should find all answers there....
-
on location......
slap on the offroad tires and do some walk and talk 3D interviews in the dirt
taking a break and getting some shots on sticks....

New Atom/ Epic pics from another project shot this last week.....
during prep at HD camera rentals I tested primes on my steadicam......on my segway.....then rode over to show off a few blocks away at the ET offices
(see link click here )
With short primes
and low mode with longer angeniuex rouge zooms....

Not cool at all...bad form on thier part.
makes me glad I bought GPI.....I'm another extremly happy GPI PRO customer...
-
oh nevermind....it was the end of a long day.....I misunderstood.....
I bought a yeager cart jr. as well. I thought you had custom pieces to fit the yeager. Nevermind. I'm getting custom cases done at a&s to fit inside my new cart.
probably just end up fab'in up a vest hanger and riggin up a docking post.....
Nice deal you got there for someone......
-
your kidding....me....I just bought one today at filmtools....
do you have a picture?
wanna sell the vest hanger and the steadimast and side tray?
-
Yup that was your vest.....I bought your rig from Todd....execpt now I have new Pro arm and vest....still have you GPI name plaque with serial number!

This pictures are great!
Spaciba!

Moses pole?
A AC i use showed up with one for me at on a 3D shoot recently and it saved my ass...
I'm now a believer in it.
I love Heidi Klum...

as far as i know they are using cmotion Cvolution to control the focus/convergence....with that system you have have up to 4 handsets! talking to the same camin/controller box/mdr
More than likely they only had one controller!
...plus I'm partially to most of the time just setting convergence and not pulling it.....YMMV.

posted on another thread....wanted to add to this post.....
very cool single camera 3D solution....using a Phantom 65.
article and cool behind the scenes video...

How was IO and convergence adjusted?
Convergence is adjusted it seams by shifting the lenses.....best way to do it actually as you do not introduce any keystone distortion....
more info here

I have never felt a thing.....

Still available....email me!
Great vest.

these configurations usually have a fixed IO. Convergence can be made to be adjusted but complicates the system. You are much better off adjusting convergence in post or if your broadcasting with the Sony MPE200.
But since you have to slice and dice the frame before it goes anywhere kinda makes this system no usable for live broadcast since it has to go thru a post process. In fact these systems usually introduce alot of distortion that also has to be corrected before viewing.....so it's definatly more of a feature tool.
While it might seam like an elegant way to solve the problem these single lens/single camera solutions all have a multitude of issues and limitations.
Which is why after all the prototype systems i have used we always go back to using a beam splitter for real critical work.

dig your setup neal...

Cool!
I help create a prototype phantom65 single camera 3D system a few years ago (with abel help!)
Very cool that someone else picked up the idea!
Post more pictures and info in the 3D steadicam thread.

I took the arm to Robert Luna at the request of an interested party. After close examination and testing, Robert came back saying "the arm is in great shape" a recommends it as a good buy.
So there you have it, clean bill of health from the man himself!
Call him if you want to here his opinion first hand.
Meanwhile the arm is still for sale. I'm taking offers.
Throw me a number.

I now wanted to test the improvement on my steadicam.
First I wanted to show how we used to have to mount the rig on the sled. We had to add height to enable us to move the rig back. So we used to mount a dovetail to the steadicam dovetail, then mount a hybrid to the rig and slid the rig onto the dovetail. The hybrid also provided a place to mount the rods for either the balance compensator or a counterweight battery.
As you can see in the picture below, the total "stack height" necessary made it so that the distance from your gimbal to the CG of the rig increased. This makes the steadicam more "top heavy" thus making you have to extend your post and making for a long rig. This of course can present many problems to the operator. The batteries being so much closer to the ground can inhibit you moving over objects, going over stairs and makes operating on a segway much harder as the batteries are now banging into your tire.
You can see the stack height illustrated by the yellow line.......also note the position of the rig over the post illustrated by the red line.
Now with the NEW sharkfin, you can drastically reduce your stack height while maintain the same forward position over the post. Notice the dovetail is gone and the hybrid (I now run the rods of my steadicam dovetail.)
Notice we lost close to 2" in height and distance from the gimbal! This means a shorter post.
