My best looking negatives are the ones made on Agfa 25 and Tech pan. A few years ago I had done some comparisons between techpan and Ilford 100 just by changing film backs of the same scene, there's just no comparison. The SWC can record an incredible amount of detail and outresolves the Delta film. How does Ilford Pan-F compare to Efke 25 (in terms of tonality grain and sharpness ) ?
