ADOX is currently selling five different kinds of slow speed 35mm films.

CHS 25 which is the true ADOX (KB 14) emulsion from the 1950ies.
This film is coated on a triacetate base and shows the unique charakteristics of a 1950ies film.
If you are in doubt about this, Jerevan, try a roll and you will see that the greyscales and spectral response are completely different from a modern film.
The film is neither cheap nor easy to handle yet very succesfull on the market due to its unique look.
There is no special developer necesary for this product.

CHS 50. Another true ADOX formulation (ADOX KB 17) from the 50ies.
Very much like CHS 25 in spectral response yet much easier to handle because it has a wider latitude.

CMS 20. Our highest resolution product. This film resolves up to 800 l/mm and makes grain free enlargements from a 35mm negative up to 1 Meter x 1,5 Meters possible. It needs to be developed in a special developer (ADOTECH).

ORT 25. A very new film emulsion developed in 2003. Better mechanical properties (surface hardening) than the historic CHS series and coated onto a clear PET base for reversal processing. Very high resolution of up to 300 l / mm and a very modern anti-halation layer between the emulsion and the base.
This film can be reversal processed. For regular development (negative) it needs a soft working developer or at least a developer with good equalizing capacity.
This filmīs individual components are produced in three different factories to make this possible. It was quite a logistical challenge to bring it to the market.

NEW PAN 25. Very much like ORT 25 but with a panchromatic emulsion. It has the same clear base and AHU (antihalo under the emulsion) and also needs to be made step by step in three different locations until we can sell it.
This film can be reversal processed (unlike the clasic CHS series).
For regular development (negative) it does not need a special developer.

None of these currently offered films is based on APX technology.

I hope this answers all questions regarding the properties of our slow speed films and explains why we have so many different ones.

Best regards,
