Kodak Vision 3 film change?

[Jay Stewart]

So I'm hearing indirect rumblings that Kodak has recently changed their Vision 3 stocks - the 5219/7219 & 5207/7207 - and have consequently skipped over a number of emulsion numbers (for example the last batch of 5219 was somewhere in the 116-120 area and have now gone to the 200's while retaining the 5219 label), and they are instructing people not to mix in the 19's instance the 100's with the new 200+ emulsion. I'm curious if anyone can confirm this, and if so, what exactly have they done? Some people I've talked to have said it's no big deal.

 

Thanks
