Practise 35mm camera
Posted 03 February 2004 - 04:41 AM
I am putting together a practise camera to use on my GLIDECAM GOLD rig. I come from a TV background and have used many video cameras on the rig, digi beta, SX etc and the arm holds it no worries. I have also used a SR2 and SR3 with plenty of adjustment left on the arm. I would like to simulate the weight of a 35mm camera to test the gear. I want to make 2 plywood sides in the shape of a Arri 435 then stick a small handicam in the middle. What I am chasing is the actual size and weight of the camera. I would like a weight that includes a lense, loaded mag, video spilt and any other bits that would be standard in a steadicam setup.
Any notes or details would be great,

I used to own Jacques Jouffret's wooden Moviecam Compact mockup. I found that a practice cage never totally can mimic a Camera for practice. (Duuuu!!!)
On my PRO Lite I was never able to get the rig in Dynamic Balance, using my practice cage. The moment I put a 435 or a LW2 on it, it was in perfect balance... comming to think about...it could have been me...
I know of operators that have an arrey of mock ups for practice...
The best would be to go to a rental house and get the measurements of the Camera of choice as well as the weight with loaded mag, lens, Mattbox, etc..., or an ARRI book would do the trick as well... at least for the data. Call ARRI and ask them for their support, most of the time they are very helpful to up and coming Proffesionels...

Sadly, I just spent the last ten minutes ttrying to dig up any pics on the web, but I came up with zilch. Oh well... I can just imagine one of those beasts on top of my Ultimate!

Macca here from Melbourne, also grew up in Maroocchydore. Unfortunately its all true. You need the real thing to see how your rig will react or to do an arm stress test there is dive weights. You should contact Cameraquip in Brisbane. They have all the gear there and will not mind if you you want to go play with gear on their premises. If you think of upgrading to a larger rig then here is one for sale in the classifieds. I know the owner, great bloke.
All the best

- Body 435ES with 100% video top
- ARRI Steadimag with 400 feet Kodak stock
- 2 Camera Plates
- NO Lens nor Mattebox
- 14.5 lbs
Add about another 4.5 lbs for a Cook S4 and an LMB-5. Don't forget the FF motors and cable which should get you into a ~20+ lbs set up.

as everyone mentioned it´s hard to imitate an overall-35mm-wooden-box because of the big differences in measurements and weight.i myself just use long,unhandy steelplates that i can srew together ,to train for different weights.i also bring my rig out of balance purposely sometimes,to imitate cameras with coaxial mags.(as the 535 !) once you´ve done a 35mm camera you will realize that (as funny as it sounds) most of them are actually easier to handle than a betacam (if it´s not an iron-pig like a BL4 or a 535....outsch!)
cheers and good work-out

Ha... so it comes full circle...
I was actually looking for 435 parts when google directed me to this post.
Originally I was looking for a practice weight/ demonstration weight. As it turned out, getting a mock up or weight plate made was almost as expensive as getting the real thing. Ended up with my very own Arriflex 435 ES... I would have never imagined. A guy was selling, I put in a ridiculously low bid and he said yes!
Funny how life works...

A weight cage, rather than plates screwed together, will get the c.g. of the "practice camera/weight cage combo" as far away vertically as the c.g. of a "real" camera. If the cage is relatively thin side to side and long - like some camera/lens/mag combos, it will have some pan inertia similar to a "real camera."
If the weight cage is not long enough or inert enough to mimic a specific camera & lens combination, one can extend the batteries and monitor on the sled to increase the pan inertia and get the same effect, and/or mimic the pan inertia of any camera/lens/mag/sled combination.
The advantage of using a cage and practice camera is the ability to record and play back easily, and have a very,very wide zoom range with which to test your skills, and the ability to change the weights to mimic any camera you might encounter.
In terms of behavior and operating "feel," a mass is a mass is a mass and nothing more.
On the other hand, with a new camera I always had concerns about the exact shape of the camera, how to attach it, cabling, outputs, and the like. That's what prep days are for. The "operating feel" can always be adjusted and/or accommodated for, and better yet, adjusted for the specific shot. - that's what practice is all about.
