take a look at the pictures please.

This lens support is made for a PL-mount adaptor – so, yes it is solid.
 
But, if you plan to use this special adapter (vocas PL-mount support)
you have to cut 2mm from the VanDiemen ISCO's rear element !!!!!!
 
The Vocas inner diameter is 2mm smaller than the VD ISCO …
 
Again, please take a look at the pictures.
 
bye.

You get a more robust lens but you loose a bit of flexibility – because of it`s design (as mentioned before).
It becomes a real "fat lady" after the mod. And with the close focus mod done you'll need a FF with a faster gear ratio (2:1 like the Arri Cine FF). And this FF isn't a lightweight at all!!
 
 
When I got my ISCO back from VD, I decided to mod the mod.
 
A friend of mine – "SFX Lange" based in Hamburg – did the following:
 
- we made it noticeable lighter (the mount is the heavy part of it)
- we've added a solid lens support (Vocas) 
- we attached a torque motor on the lens support (redrock micro remote)
 
The ISCO is held by the lens support and is just "pushed" in front of the lens (not screwed!)
Now I can change the taking lens within seconds, without a recalibration of the ISCO is necessary.
 
Have fun!
