Hi, how about those older 12mm rods? Are they not in use today at all?

never seen those in use with any camera. my Cameflex original battebox has them but never used them because I don't have 12mm base plate, have just adapted 15 and 19mm stuff to work

I just got base plate that has 12mm rods. I've cleaned it and it works great. Problem is my follow focus is in 15mm. Any ideas?

if the rod spacing is the same you can just have the nearest machine shop to make you some adapters similar to these ones but from 12 to 15mm:  http://www.ebay.com/...JAAAOxy0zhTM6tf   

 

even tape would probably work for spacing as a temporary solution but as said the rod spacing needs to be the same than in 15mm system

It's sort of tricky because those adaptors are designed to allow smaller rods to go into larger holes, whereas our correspondent needs something that would allow larger rods to be supported in a smaller hole.

 

On the upside, that may just mean a sort of plug adapter with a 12mm OD and a shoulder to accept 15mm rods.

or did you mean 15mm light weight rods instead of studio rods? then you should have a custom adapter to be made. but even then not very difficult job

So you need an adaptor with two 12mm holes 90mm apart and two 15mm holes 60mm apart.

 

I'm not sure what the situation is as regards rod to lens height. I don't believe it's standardised.

Thanks. I think I could do that myself. It's a shame they don't make any adapters tho. And to my surprise many people have no idea about 12mm rods at all, even those who work in the industry. Strange.

I don't know if I want to go to 15mm tho. Maybe besst bet would be to go to 19mm as they are in use more often. Correct me if I'm wrong, 19mm are 104mm apart, and 15mm studio are 100mm apart. Right?
