Adox CMS 20 II 36-Exposure 35mm Black & White 135 Film

Adox CMS 20 II is an ultra-high-resolution black-and-white film, engineered with a special emulsion that achieves unparalleled sharpness and fine grain. When paired with the dedicated ADOTECH developer, CMS 20 II reaches a nominal speed of ISO 20 for pictorial photography, producing incredibly high contrast and detailed images. The film’s extraordinary resolving power, up to 800 lines per mm, allows for enormous enlargements without any loss of resolution, making it ideal for technical photography, landscapes, and any setting where fine detail is paramount. With its orthopanchromatic sensitisation, CMS 20 II doesn’t require green filtration in portraits, and its clear base makes it suitable for creating ultra-high-resolution slides.

Hazel ★★★★★

If you need extreme detail for large prints, this 35mm film delivers on its promise—the emulsion captures texture I’ve never seen with other rolls. Just be ready with a sturdy tripod for anything below bright sunlight, as the ISO 20 speed demands good light.

Samuel V. ★★★★★

I was blown away by how sharp this film renders fine details, almost like looking at a digital file. Even with dense foliage in my landscape shots, every leaf edge stayed crisp. Definitely worth the extra care needed in development.

Victoria ★★★★★

The level of detail in the shadows on this film is incredible, even under a magnifying loupe. I shot a still life with tiny text and it resolved individual letters perfectly. Definitely the sharpest 35mm film I’ve used.
