I don't see any indication that there is any c41 film > 800 ISO that is still being manufactured anywhere. As I said in my initial post, Fuji Press 1600 was the last 1600 speed C41 film being made, and that was discontinued years ago.
Porta is very expensive film. I think I'm going to buy a lot of Supra Xtra 800 and see if I can get it a stop or more. That stuff sells for ~$3-4 a roll.
Thanks for that, I'll try a roll or two and compare to Portra 800. I don't expect it to be quite as good but if it's close at an extra stop of speed it could be handy. I don't shoot enough of it to be too concerned about the price.
Portra 800 is very good, and I can get it in 120 which is even better.
If it's listed on Fuji's website as a product, it's very likely still being manufactured. I went to Fuji's .au site to look for indications that they were still selling 1600 speed film there, to no avail (in fact Fuji doesn't list *any* 35mm film on their .au website at all). However, I did email their PR department so we'll see what comes of it...
