I have for sale several new high quality diopters, fitting ISCORAMA-36 lens (or anamorphic adaptor) for 72mm
filter thread allowing to break the 6ft / 2 meters barrier this lens has. Price is USD125 (EUR100 in Europe)
shipped as registered letter and paypaled.

Please contact me offline via postmaster@macrolenses.de

Cheers, Klaus

Test at closest and furthest position, all shot full open, vertical. Focus span is about 1.1 meters
using that close-up diopter, from about 0.90 meters to about 2 meters. Seems to be a
multicoated achromatic diopter since I cannot detect CA and there are two strong and two very
faint reflections visible, which indicates a cemented achromatic lens.

1) Closest focus, ca 0.9 meters (about 3ft) object to lens front (sharp focus at mark "30")

2) Furthest focus, ca 2 meters (about 6ft) object to lens front (sharp focus at end of books)

Only one left and that will be it most likely, since my supplier told me that the stock is depleted and the factory does not make them anymore.

I have recently found and purchased an Iscorama - 54 - It should arrive next week. I'm wondering if these diopters will fit, and if not, what size should I be looking for?
 
No they don't fit since they are 72mm diameter. The Isco-54 has a much larger diameter and I haven't seen achromatic diopters of that size. If I remeber correctly it also does not have front threads to mount filters, since it was mainly designed for home projection and not as a taking lens (although doable).

Correction: the I-54 seems to have 95mm front filter threads, so you could mount a diopter of size 95mm - just havent seen on in +0.5 in that size....
