I have one roll of the 'original' 120 CMS20 left in the fridge. And I can confidently say to Adox if it's your bank manager that's the problem show them the price of Adotech IV and explain how much of it a photographer needs to process one roll.
Well, as someone who is using CMS 20 and current CMS 20 II for years, you are missing the decisive point:
CMS 20 II is microfilm-based and simply needs a special developer to offer its full potential in pictorial fine art photography. Adotech IV is that developer that leads this outstanding film to its optimal performance.
Of course such a high-tech developer is more expensive than a standard mass volume simple BW developer recipe. Because
- many, many years of expensive R&D were needed for that product
- it is a niche product, produced in much, much lower volumes than the standard BW developers.
Therefore comparing the price of Adotech to normal developers is unfair.
But there is an even more important aspect: The value you get!
I have tested this film really intensively in my photographic test lab. And I even reached the diffraction limit (!!) at f5.6 with this film. No other film and no other sensor can do that!!
With CMS 20 II in 35mm I have surpassed Fomapan 100 in
4x5" (!!).
With CMS 20 II in 120 you surpass every other standard BW film in 4x5" in detail rendition. You get large format quality with rollfilm.
And on that fact your financial considerations have to be focussed:
CMS 20 II 120, developed in Adotech IV, is much cheaper per shot than 4x5" normal BW film.
Therefore in the end CMS 20 II / Adotech has an excellent price-performance ratio and can even safe you money. With it in 120 you get large format quality, but at significantly lower price and all the advantages medium format film cameras are offering compared to LF.
