GOST to ISO conversion chart
Posted on April, 19 at 8:32 am
Many people purchase older Soviet cameras and wonder how to set the film speed. Older Soviet cameras measured film sensitivity settings in GOST units instead of the newer ASA/ISO or older DIN speeds. The settings aren’t far off, this is a table to map GOST to ISO/ASA:
| GOST | ASA | DIN |
|---|---|---|
| 11 | 12 | 12 |
| 22 | 25 | 15 |
| 28 | 32 | 16 |
| 56 | 64 | 19 |
| 90 | 100 | 21 |
| 110 | 125 | 22 |
| 140 | 180 | 23 |
| 180 | 200 | 24 |
| 360 | 400 | 27 |
| 560 | 650 | 29 |
| 720 | 800 | 30 |
| 900 | 1000 | 31 |
| 1125 | 1250 | 32 |
| 2880 | 3200 | 36 |
