Adox CMS 20 II Pro 35mm - ISO 12

Our Price: £5.00 GBP



One of the sharpest black-and-white 35mm films in existence, the fine grain and low light sensitivity means that prints can typically be enlarged to over 2.5m diagonally without loss of resolution or detail! ISO 12 (up to 20 depending on development process) means you will need lots of light or a steady hand/tripod - but you will be well rewarded with a super-premium look

Colour: B&W
Type: Negative
ISO: 12
Exposures: 36
Pack size: 1

Adox is one of the oldest photographic brands in the world, established in Germany in 1860 by Dr. Carl Schleussner - who worked on early wet-collodion plates and X-ray plates. The company started marketing their own cameras in the early 20th Century, and introduced a line of B&W films in 1952 that became renowned for their sharpness of resolution. A difficult end to the last century saw the brand change hands multiple times - and now Adox films are produced by Fotoimpex across manufacturing plants in Germany and Switzerland. Their products remain very high quality with a focus on emulsions that resolve incredible levels of detail and contrast.

Incredible detail and sharpness!

Such a unique and extraordinary looking film stock, with incredible detail, sharpness and dynamic range. With such a low iso film it makes you slow down the process even more, and really concentrate on the composition - also luckily the sun was out at this Glastonbury in 2019. Definitely one of my favourite b&w film stocks to shoot, and highly recommend trying one of the incredible ADOX films, especially if you get chance to at a sunny summer festival. :'(

Truly amazing film

I perhaps did not get the best out of the film (Not the best camera or developer). However what I did get was some fantastic supper fine grain photos and contrast like no other! I developed it in Xtol Stock for 6.30.

Perfect for: Architecture, Studio work

You'd be amazed how sharp your camera's lens actually is. As per manufacturer's recommendation I developed in Adotech IV to get the best sharpness. So home developing is probably best unless your photo lab keeps that stuff in stock. It was hard getting the film into the Paterson plastic spool. It's harder to handle than normal film for some reason. Be careful. Given the speed, you'd probably use this film for tripod shots of static scenes and objects, but I got good handheld results on a sunny day, too. Scans of the negative look almost like they have had some work done to it already. Objects are very defined. Pictures won't need much editing. Great film, unlike all others.

Very good if you use it right

This is an extremely fine grain and extremely slow film. You want this film if you intend to print large, the amount of detail is unparallel to any other film I've seen enlarged. However, the physics of everything imposes constraints upon you. The speed of the film (I shot it as ISO 16, but going ISO 3-6 is not uncommon) means it is hard to not use a tripod. If you are using this film, you are looking for good details. Since you are looking for details, your lens should have good optical properties. Adox says CMS 20 can take 800 lines per mm; Nikkor 50/1.4G will give you 60ish, so if you are looking for details, you'd better use good lens, you won't see good details with a Holga. Also, process it in its own developer, this would allow you to use ISO 20.

If you get the right equipment and spend time using right chemistry, you are going to get amazing results that are impossible with other films. If you don't, well, it's a slow contrasty film.
