I recently imported a carton of 400 rolls of Shantou Era B&W film from China. I have been told repeatedly by members of various online photo communities that it is better-regarded in China than Lucky, which reportedly lacks an anti-halation layer.
I have sold the film and won't be repeating, so I am not offering to sell any at this time. However, if you're going to be purchasing film in China, I would recommend Shantou Era over Lucky based on my own experiences as well as word-of-mouth reports I've gotten.
It cost me quite a bit to ship the film here to the US, so I had to sell it for quite a bit more than it sells for in China. I am told it sells very inexpensively if you are in China.
Here are some of the results I obtained using the stuff myself:
In Diafine:
Dead Link Removed
In HC-110:
Dead Link Removed
In Rodinal:
Dead Link Removed
In D-76:
Dead Link Removed
Compared to Arista.EDU Ultra
Dead Link Removed
Please note that many of the images online were early and experimental - after most of them, I ended up scaling back my dev times substantially, particularly with Rodinal. I now process Shantou Era in Rodinal 1:50 for 12 minutes @ 70 degrees F.
I processed the negs, scanned the results with a Konica-Minolta ScanDual IV on the highest resolution with Vuescan (linux) and resized using GwenView (linux). I did not adjust levels, crop, or retouch the scans in any way, so the dust and scratches are the fault of my processing, pretty much. What you see is what I saw, to the nearest extent possible.
Hope you find it helpful.
