The oldest konica 750 I have expired in 1990 and has a bit of base fog but prints just fine. I sold about 300 rolls, gave some away a couple years ago, and have only heard good things regarding the results. 9 minutes in pmk, using a jobo speed 4. I print with a dichroic head. My August print special is an 11x14 from Zion National Park. Should be live on my website in a day or two if you wanna see the results.
