Commentary
Full specifications of many (if not all, at the time) Iscorama lenses and adapters, and Kowa 2x 8z adapter. How official? Don't know- Widescreen Centre was a reseller, but they could've easily asked manufacturer for details. But uncommon.
Most interestingly, there is a Iscorama lens meant for darkroom enlarger printing shown called the Iscorama-Magnascope. It's 1.5x squeeze, fixed focus at 0.195m and paired with a Schneider Componon 50mm f2.8. I have never seen one of these before, and I have not managed to find any reference on archive.org.
There is also an announcement of an Iscorama copier lens "which allows ordinary slides to be copied on to the widescreen format for inclusion in your programme." Unknown what this is and have never seen anything related from ISCO.
The optical diagram for the Iscorama is only roughly accurate and the one for the Kowa inaccurate (have seen disassembly photos), so haven't drawn attention to them with higher quality scan. Dated/belittling depiction of woman common to photographic advertising on page 3. |
