24 exposure rolls are all thats left.
I grabbed a few 100 footer's and when I went back to re up...it was gone :(
It's not uncommon with film to set up a line, run off several master rolls, break down the line, set it up for another film, then run off several master rolls, break down the line, continuing to run through a bunch of products, eventually looping back to the first one. It's completely possible to manufacture a modern B&W emulsion on the same line as colour emulsions, many are coated in several layers, just like colour. For Kodak the odd man out was Kodachrome, it needed special manufacturing, which took a long time to set up. The master rolls sit in the freezer until there is a call for product, they take them out, thaw them, package them, and ship the film out.
Technically therefore, most products, except the ones in the coating plant, and the ones being slit and packaged, are no longer being manufactured. Now I just looked on Kodak Canada website for Plus-X, normally when Kodak discontinues a product, they post a discontinued notice on the website, there is no discontinued notice for Plus-X.
Officially, only Plus-X in 120 was discontinued. 135 is still a current product. I have no idea if they are still intending to produce master rolls when the current one is gone.
As far as Kentmere films are concerned, Harman took over Kentmere's photographic side (they also manufactured packaging) and closed the Kentmere coating line. All Kentmere products are coated in the Harman/Ilford factory in Mobberley. Kentmere is therefore now a Harman brand (not a subsidiary company) & the new films seem to have been launched as an economy line and in 35mm only.
Side by side comparison of 35mm Ultrafine Extreme 100 I ordered a couple weeks ago shows identical in every way to Kentmere 100 (aka Ilford Pan 100 in some countries.) The only difference is the brand ID on one side, "Ultrafine Extreme ISO 100". Frame numbers etc. are Ilford. More importantly, the emulsion (check the nice relief image when viewed at an angle), density, grain, developing times are the same as Kentmere. It's an excellent film and very close to FP4+ but with a little more grain (in Rodinal). Lovely film. It has the flattest acetate base of any manufacturer, which makes me even more certain it is Ilford. Photo warehouse is clearly bulk loading this themselves as the frame numbers don't always start on 0 or 1 and often proceed to 42 with a space, then restart at 0 on the same roll. The rolls are 36 exp. length.
Anyone tried and perhaps have examples of the 400 version?
