Foma should be able to provide this information for their own products. You could look up the times for FP4 Plus and Plus-X films and average them as a starting point. Make a test before taking any important photographs.
Thanks.Good points you made.I will give Forma a buzz in the new year.You see the film is so cheap I thought I'd give it a punt!Ilford are closed until Monday so I will call both companies next week.

Generally Foma films take about 30% less developing time than Tri-X, FP4+, Plus-X, etc.
For instance, my developing time for Delta 100, and Tri-X film in HC-110 rotary development at 1+100 dilution from syrup is 11 minutes. For Foma 200 and 100 it's 8 minutes for the same density.
Hi all.I just got an Email from Foma.They say that 8-8.30 minutes @20c in DDX will give medium contrast negs.They were really helpful and I will be buying more Foma products when I return to the UK.

Thanks for the post. My first roll was over-developed, and many photos had a distinctive look to them that I didn't like and found many fomapan 100 photos online that with that same look. I suspect that because fomapan needs less time, it is commonly over-developed.
If you look in the data sheet, you can see the explanation. The photos show medium highlights being too bright, and the listed response curve for the longest development reflects that.
