Henning Serger and I did some tests with Lomography CN100 and Kodak ProImage 100 and we came to the conclusion that they were both the same.
I’ve shot and scanned several rolls of Kodak Pro Image 100 and the “Made in USA” 135 Lomo CN100 over the past couple of years. To my admittedly untrained eye, the two films look like they’re from the same ‘family’, but not identical. Lomo CN100 seems to have a bit more grain, and just has an older, less refined look to it. Pro Image appears to have better skin tones and contrast. It has a richness and depth to it that Lomo CN100 lacks.
That being said, I agree with what others have said in that it makes no business sense for Kodak to make a special run for Lomo when they can supply the Pro Image 100 they’re already manufacturing. So I guess only Kodak and Lomo know the truth, and they’re not going to say.
