CDS Cell resistance and Substitution list

Resistance measured with naked cell held against Light Box set to k-factor 1.3

Also note that the values are average where several cells have been measured and a 50% difference can usually be adjusted provided the difference is linear in relation to the original cell.

Matching notes:
Even though there is a great difference I have successfully used a cell from an Olympus OM.10 in an Olympus XA.2.
You can also use Gelatine ND filters to increase a cell resistance: ND 0.3 = 50%, ND 0.6 = 100%

USER NOTE:
Please report any additional cell resistances you have measured in the same manner so they can be added to the table.
