Yes the Z6 with the ES-2 Adapter on a 60mm Micro G lens. The film was Kodak Pan-X so I'm a bit surprised at the grain. I know I developed it myself so that may have contributed to it.
I believe I was using good amateur quality lenses (50 1.8D, 35 1.8D(?), and the old 85 1.8) but compared to modern optics and digital processing, the images simply weren't as sharp or detailed, and the slides certainly had a definite color signature. I can tell as soon as the image comes up on the screen which ones were shot with the 85 which is clearly the sharpest lens I used.
If you had showed me back in '74 the quality, consistency and color accuracy of the travel images I get now, it would have seemed truly magical. I hate to sound like an old curmudgeon (which I am) but I simply don't get the internet angst when the 100 corner pixels aren't pin sharp or the wailing when the camera focuses on the fourth and not the fifth eyelash from the left.
