I had never heard of it until freestyle had this really cheep "legacy Pro 400" which I bought a small supply of, and at first was not too impressed, until I played with it some and started to get some good shots. Stocked up on a whole bunch of it, and started to check bout what it was. Discovered it WAS Neopan 400 and started to buy some of that, but it was twice the price of Legacy Pro.
When Freestyle ran out of legacy pro, I started to order ten rolls at a time of Neopan 400 every time I got something from the mail order places, hoping to see the first three digits of the emulsion number increment. It did'ent.
I have run out of all but a few bulk loaded carts of Legacy pro, and have perhaps 60 of the Neopan 400 in my freezer.
Presumably by the time freestyle was allowed to buy it as a private label fujifilm had decided that it was not going to continue. The Neo400 I bought subsequently to freestyle running out of LP was all from the one batch with a slightly higher emulsion number than the LP400.
