No other film is sharper, no other film is more
finegrained, no other film resolves more lines per mm
(up to 800 l /mm).
If used in pictorial photography the film achieves 20
ASA of usable speed in ADOTECH developer. If used for
high contrast purposes the usable speed increases to 80
ASA. If developed in non dedicated low contrast
developers (HC 110, cafenol etc) it can be exposed at
6-12 ASA. The film achieves grain free enlargements of
up to 2,5 meters diagonally. This equals mathematical
about 500 Megapixels. 12 Megapixel, which is today's
standard in high end digital cameras equals 2,4% of 500
Megapixel. This just as a little comparison on the
The special monodisperse ultra high resolution emulsion
of the film makes it possible.

ADOTECH developer brings perfect halftones and
increases the speed to 20 ASA and creates images no one
would possibly believe to have been made with a 35mm
ADOX CMS 20 has an orthopanchromatic sensitization
which differentiates perfectly between colors. The CMS
„sees it all“. No green filter is necessary
in portrait photography.
The film´s base is totally transparent making it
theoretically possible to reverse it and use it as an
ultrahighresolution slide film with extreme projecting
In order to do so you need to combine a reversal
process with adotech as a first developer.
Once you shot this film you never want to use anything
with less capabilities unless you have too.
Think you can´t shoot at 20 ASA?
Let us explain this to you:
If you want high resolution pictures you need to open
your lens aperture to one stop below maximum opening.
Otherwise the lens defraction will lower your lens'
resolution down to half of what this film can capture.
Best lenses are F1,4 high speed high quality lenses
like Nikkors, Summiluxes, Zeiss, Rokkors or Canon
This puts you effectively to between F2 and F4.
Any normal winter day 2 hours after sunrise and up to
two hours before sunset will give you something like a
125th or a 250th of a second at F 3,5.
Therefore the film can be used under almost any
condition where it makes sense to use it because there
is actually something to see.
More speed would force you to stop down too much on a
sunny day, letting slip what your lens can actually
In bad light conditions the film makes no sense because
you barely see something so you might as well use a
lower resolving film to capture this.
Basically, you can shoot everyday with this film unless
the sun is gone or behind heavy clouds or you want to
shoot indors without a flash.
All CMS images in the catalogue and on the ADOX webiste
(www.adox.de) are shot free hand at F2,8 with a 35mm or
a 50mm lens.
If developed in ADOTECH you can expose CMS 20 to 20 ASA
and get images with perfect halftones.
In low contrast situations and with prolonged
developing times the achievable speed increases to up
to 32 ASA.
Other than common microfilm developers ADOTECH is very
resistant against streaking or producing turbulence-
clouds next to the film holes. Still you have to use
some general caution in agitating the filmtank.
