Yes, I think I read the same thing on the eSIF - I doubt I have any Series VI
filters I could use.

I don't really need any extra extention, just wondering about those threaded
holes !
By the way, which cine lenses are good for this ?
I have used a 30/2.8 Rokkor enlaging lens reversed which works pretty well and
because of the way it's constructed with an exposed rear element on a narrow
shaft (would normally project into the enlarger bellows) it allows some light
to get to the subject.
