Quick answer

For most vintage cameras, 620 film is the correct format, but 120 film can be adapted with a spool swap or re-spooling. Choose 620 film for a direct fit, or adapt 120 film for wider availability and lower cost.

Spool design difference

620 and 120 film use the same 6 cm wide emulsion, but the spool is different. 620 spools have a smaller diameter and narrower flanges than 120 spools, allowing them to fit into compact cameras like Brownies. 120 spools are thicker and may not fit in the same camera chambers without modification.

Availability and processing

620 film is less common than 120 film, but specialty brands like Film Photography Project still produce it. Processing is identical for both: standard C-41 for color negative, or black-and-white chemistry. If you adapt 120 film, you can use any lab that processes medium format.

Trade-offs at a glance

  • Use 620 film if: Your vintage camera has a 620-specific spool chamber that cannot accommodate a 120 spool. Buying 620 roll film ensures a direct fit with no modification.
  • Use 120 film if: You are willing to either re-spool the 120 film onto a 620 spool or trim the flanges of the 120 spool to fit. This gives you access to a much wider range of emulsions and often lower prices. Re-spooling requires a darkroom or changing bag; trimming flanges is permanent and may damage the camera if not done carefully.
  • Adaptation method: The most reliable method is to buy a 620 spool and re-spool 120 film onto it in complete darkness. Alternatively, some photographers file down the 120 spool flanges to reduce its diameter, but this risks debris inside the camera. Always test with a sacrificial roll before trusting important shots.
