Hi All,
I was awaiting the arrival of an Isco Ultra 'Scope cinema lens and my thoughts for days had been on how to mount the beast, since it wouldn't fit standard holders in 8 or 16mm.
Chip Gelmini's wooden cradle was what seemed the most useful for the least money, but since I wanted to keep using my regular (smaller) folding table for the machines, I kept coming back to the idea of some sort of standing ring mount.
Having found nothing on-line (and god knows I looked at every kind of ring/washer/holder...) when the lens arrived, I suddenly realized that one of my microphone mounts had the right circular diameter to slip onto the middle of the barrel of the lens (about 3-1/4-inch diameter.)
This is the item, it's called a spider mount:
The company is Marshall; they sell cheap Chinese-made microphones and, conversely, the spider mounts are quite reasonable too.
Take the rubber bands off, and the center mount comes out.
The lockable ring tilts, and the base screws onto any mic stand of your choice (Atlas with cast-iron base here):
Since this is very much the "raw prototype" ![[Smile]](smile.gif) I put some Velcro around the lens to help firm it against the ring and to avoid scratching the heck out of the barrel.
The most amazing thing is that the little swivel lock holds the big lens just fine. Just make sure you place the ring towards the middle of the lens to minimize front heaviness.
The little hooks that hold the rubber bands on the ring can be gently bent out with a pair of pliers to act as little 'fingers' holding the lens in both directions.
Just for a rough idea, nothing really 'set', here it is in front of the 1200, and with another plank or so, the machine will be pretty well aligned:
With my Eiki, in terms of height, it's very close by itself:
If you are planning to go the Isco commercial 'Scope lens route,
the Marshall mount for the V57 or V67 mic is the one I used, and they are available at many music stores. Other budget brands abound too these days.
For other lenses, consider this an idea. You may be able to find a mount that will work for your lens too, as the 'spiders' come in different sizes.
I was very pleased with how snugly these items fit together, even before making any serious decisions about padding the barrel and such.
The ring and the little lock may look scary with so much glass riding on it, but mine felt comfortable from when I put the lens on, and I am not a risk-taker with such things. At most, the washer in the ring lock may need to be changed a bit more often. Equilibrium helps in the mounting.
Now I really need to buy a Super-8 'scope feature... ![[Roll Eyes]](rolleyes.gif)
Claus.
