Testing Repaired YASHICA DSB 50mm f1.9

[pentaxpete]

The Yashica DSB 50mm f1.9 on my FR-1 developed a 'stop-down' fault -- it was usuable only at full aperture so I sent it to a 'Contax Expert' as he said he could do 'Yashica lenses with same mount' It cost £35 -- he had completely to disassemble lens and clean oil off aperture blades then get them back together again. So i loaded some 'slow ORWO NP20 film I had been sent and rated it at 40 ASA and processed in liquid 'Promicrol 1+14' as I had done a test.

Well, you shouldn't feel yourself in need for sharpness!

Thanks for comment -- of course, as with all 'Digital Scans from negatives; I applied some 'Unsharp Mask' but only to bring it to the same level I saw of negatives under a x6 magnifier.
