Problem with a lot of these Rollei films is that they are basically rebranded aerial films. And, now that Rollei is out of business their availabilty is only temporary anyway.

Efke would be the only alternative, and it appears to be prohibitively-priced. 80.50 is the equivalent, currently of about $110U.S., which is right in line with the price of the Portra 70mm films available. EUR 83 seems in line, but 166 is CRAZY! That'd come out to the equivalent of EUR 8.30 per 220 length.

I guess that respooling aerial films is a viable option, but I want films that have natural panchromatic sensitivites not extended-reds designed for foliage photography from 20,000 feet!
