The sharpest 35mm film? ADOX CMS 20 II PRO & ADOTECH IV Review

In today’s episode, Jules, Greg and I test a film and developer combination that promotes itself as
“The sharpest, most fine grained and highest resolving image recording system in the world.”
This sounds very promising and Greg, Jules and I needed to give it a try. We are talking about the ADOX CMS 20 II PRO developed in the fitting ADOX ADOTECH IV developer.
While Greg already tested the film in the early days of the first Coronavirus lockdown in Germany, Jules and I recently took it out in the snow. Greg shot a Pentax LX with two high-end Pentax lenses while Jules and I settled on the Nikon F6 with an incredibly sharp Tamron 24-70mm f/2.8 SP lens. In order to get the most out of the 35mm negatives, Greg scanned the film with his Pentax K1 while Jules used his Heidelberg NexScan F4100.
Watch the video to see how this film and developer combination performed in our test.
ADOX CMS 20 II PRO & ADOTECH IV:

I've shot this stuff on 4x5 with my Fujinon lens. I almost couldn't believe what I saw when I inspected the negatives. It was almost as if the grain did not exist, it was extremely sharp, never ever seen something like it before. You could EASILY print this 30 meters wide and have room left.

[@SilntObsvr]

"Monodisperse" is a term usually applied to microfilms. Since the original CMS 20 came out in 2005 or 2006, it's been known that this is effectively a microfilm emulsion. It may be at its best with Adotech IV, but when I used the original CMS 20 I developed in a low contrast variant of Caffenol and, with a 1960s vintage Super Takumar, had more resolution than I could then scan even from an 8x10 wet print. Other similar products are available, however; Kodak Imagelink and Fuji FR and HR, as well as Agfa Copex Rapid (which is now available as such in 35 mm, 120, and 4x5). All have very similar sharpness and resolution, and can provide similar tonal range in similar development (SPUR, H&W Control, low contrast Caffenol variants, even Rodinal 1:100).

[@ianhand5006]

I want to try some in my Minox subminiature cameras. Adox HR-50 is excellent, so CMS 20 should be Stellar!

[@peterkin1010]

Closest I ever came to that was with Agfapan 25 shot with an Olympus OM1n 50Mpmm f1.8 c f5.6 orange filter mounted on a Slik 88 tripod. Cable release and mirror lockup processed in Rodinall Got as far as a grain free 8x10 on Ilford Grade 2 paper . Great fun...

This Pentaxian thanks you for not using the typical Nikon gear in this video. Pentax retains a niche position in both the analogue and digital communities ... which helps keep prices reasonable for those of us who know the superb quality of cameras such as the LX, the K-1, and the 645N ... and the legacy Takumar glass.

[@henningserger7150]

Another good video from you, solid work. I just want to add some additional information, as I am running an independent photography test lab, being active in scientific testing for about 30 years. And these highest-resolution films are one of my regular tools in lens tests, as they are offering the highest performance in detail rendition and highest possible resolution. Excellent tools for testing the best lenses. And ADOX CMS 20 II is surpassing all digital sensors in my lens tests by a huge margin. In former times I have used Kodak Technical Pan, but ADOX CMS 20 II is surpassing Technical Pan in resolution, sharpness and fineness of grain significantly. With ADOX CMS 20 II I have reached the physical resolution limit (diffraction limit) of lots of different lenses. As an example, for f5.6 and white light that is 240-260 linepairs per millimeter (lp/mm). And I’ve got that resolution even at a relatively low object contrast of only 1:4 (two stops). Carl Zeiss did similar tests with the first version of this film, but with a bit higher object contrast. For example they reached with their ZM Biogon 2.8/25 at f4 the diffraction limit of 400 lp/mm (test results published in their ‚Camera Lens News‘ No. 24). You would need a 35mm digital sensor of at least 553 Megapixel to get the same resolution under identical test conditions. Tim Parkin, publisher of the ‚On Landscape‘ photo magazin, has also published very detailed test results: www.onlandscape.co.uk/2014/12/36-megapixels-vs-6x7-velvia/ . I have also tested all imaging chains with this film, from the shot to the final, enlarged and presented image. With scanning you have the biggest loss in detail rendition. No current scanner is able to fully resolve the incredible amount of detail CMS 20 II is recording. Even all drumscanners deliver only resolution values significantly below the real resolution on the film. But the good news is: With classic optical enlarging with APO enlarging lenses you can get much higher resolution compared to the best drumscanners. And so you can exploit the outstanding resolving power of this film to a much higher extent with classic optical enlarging compared to scanning. The same is valid for projection: ADOX CMS 20 II can also be reversal processed in the Scala reversal process, so that you have a BW transparency (slide) as the final picture. I have done several projection tests with the best projection lenses, and was able to project the resolution patterns of 220-230 Lp/mm onto the projection screen. Even on a projected 35mm CMS 20 II transparency of more than 5 meters width I could see the finest details in the picture from just some centimeters distance. You can enlarge 35mm CMS 20 II pictures as big as you want. There is no limit. By the way, the light sensitivity (film speed) of this film is sufficient to use it hand-held outdoor in normal daylight lighting conditions. With EI of 12/12° I have used this film very often that way with aperture values in the f2.8 to f5.6 range and with shutter speeds of 1/60s to1/250s.

[@LaViejaConsolada]

I was wandering why my terribly processed CMS photos apparently shows more (much more) resolution than it appears in this video. And is because I enlarged it, of course. This film is absurd: it almost reach the resolution of my 4x5 negatives (not the tonality, sadly, but that would be impossible).

Decades ago, as there was nothing else than film to take photos, I have always tried to avoid any grain and wished to get the finest and sharpes results possible in my small lab. Today, when I take sometimes images on film, beside my digital photography, I try to keep some grain on film, to have the difference and distance to the clean and clear digital world of images. What I don't like is to make digital pictures and finally spend them some grain in PS.

Your channel is fabulous! I shoot mostly Tri-X because I like the grain however I was so inspired by this episode I just bought the film and the developer.

I would be interested in trying it out in my Mamiya in medium format at some point.

[@Garacha222]

It sure would have been nice to see a comparison of ADOX against a slow film processed in a standard developer ... such as ILFORD PAN F+ in xtol, or other slow film & developer combination. I was intrigued by the clear film base concept some time ago, and I picked up 100ft roll of 35mm Rollei RPX 100 because of this. I will be testing it in xtol of varying dilutions (and possibly varying agitation schemes), and also plan to test in PMK staining developer.

Just had a look at Adox's site today and noticed this film. Read their description and went on looking for their Super 8 film, because I just thought what was said there was just the standard "this is the best film ever" kind of spiel... Seeing your test was online, I had a look and was truly impressed. Kind of like medium format results from a 35mm camera. Will get a roll or two to try... with some Adotech developer...

I think you should really upload in 4K, even if you don’t shoot in 4K. KZbin has a pretty good zoom in feature now for its apps and this makes it possible to really go in on details with videos like this.

Great work as ever gents. Adox CMS 20 is one of several in the Adox line I just wish would come out in 120! I seldom shoot 35mm except for fun family stuff, and a film like this is too good to mess around with. Can you imagine how it would look in 120 if it looks this good in 35mm?!

[@camerafusion]

Love the informative videos. Keep them coming 👍

[@chacker]

Thanks for sharing this video! Also, your scans are very high in details and this is the first time I saw the grain of this film stock occur. Personally I do scan 135 film with the Reflecta RPS 10M which can resolve something around 4500dpi. At this resolution, the real grain of the CMS20 II seems to hide somewhere within the pixels... From my own experience this exceptional film stock does offer more challenges than it's very low speed and inherent quite contrasty attributes... 1- The almost non existent grain does expose every(!) focussing / motion blur mistake. Which are plenty when shot handheld, like I did the last time using it (see my last video). 2- It curls like a spring. Even when pressed flat for a week. After a lot of time in my negatives archive folders it likes to stay what I'd consider "flat". 3- Dust. I can't believe how much dust this thin trip of polyester can accumulate. It seems to just love the very tiny one what makes spotting a scan a time consuming task. Luckily, when printed in the darkroom the dust is not that much of a problem. Don't know why that is...

Nice demonstration. I am reminded of past years shooting Kodak Tech Pan. Same slow speed,wide latitude, resolution, and special developer. To obtain the benefits, you must shoot with the care and limitations of a large format camera, making your photography slow and laborious. If your goal is an exhibit print, all of that may be worth it. If you are copying the negative with a jury-rigged digital SLR to post on media or make an inkjet print, it's a total waste of time and money.

I am using ADOX CMS 20 I / II since the introduction more than a decade ago. It is excellent for landscape, architecture, still-life (studio work), cars, lost places. But I have also used it for jewelry shots (prof. advertizing) and fashion jobs. And also made quite a lot of portraits with it, too. With portraits you have to be a bit more careful with the selection of people you are portraying, but if done right, the results are outstanding and have their own special character.

I used to mix up a long forgotten ‘soup’ , probably a version of Metol A+B. The fun was that, with a very sharp lens and the right subject , you could pass a photo shot this way of being taken on 4x5.

Totally agree. I still have loads of TP and shoot 35mm and 120 film. Using my Mamiya 1000s 6x4.5, the results are extraordinary. I sometimes shoot on a Rolleiflex but the flexibility of interchangeable lenses on the Mamiya more than compensates for the slightly better performance of the Rollei.

Thank you for the video. I have been using this film for a year now (besides others, of course). The resolution is incredible - but the downside of 12 ISO, 20 on the wild side, is very limiting for me. And then, I could not really answer my question: why don’t just use my digital ‘full frame’ camera, if high resolution is the Holy Grail?.. On film, compared to CMS 20 or more generally ‘weird films’, I prefer to use Ferrania p30: also very special, but underlines the qualities of film and is at least 80 ISO ;-) Nevertheless, I encourage everybody to try CMS 20 - it’s quite unique!

P30 is it. If they sold it in an affordable format (100ft or 400ft etc) it might be my one and only.

[@NoosaHeads]

I use Kodak Technical Pan film. (I still have a fridge full of it). To my mind, it's nicer than Adox CMS because the tones are more graded. CMS is too contrasty. (But slightly finer grain than TP). Photographers Formulary make a developer called TD3 and it gives outstanding results and 50asa with T.P. CMS can only be rated at 15-20asa, if you want the contrast to be manageable. I did take a portrait, using CMS and a Canon 85mm F1.8 EF lens. I scanned the negative on my Noritsu HS1800 and a friend printed it to 4ft. x 3ft. At close/normal viewing distances, grain was not visible. (But the picture was a little "harsh"). Technical Pan film would have made a more natural job of the portrait.

Hi, very useful and well articulated video, thanks! I have a question on "exposure-development" issues. I am an old photo-man (analog of course) and for my art research, I used to use all those low speed ultra-sharp films of the '60 of previous century, i.e. Agfapan 25, rebranded as APX 25, then disappeared... So I was using this film from its first appearence, when developer was a simple "Adotech" then I, II, III and now IV. The problem is that instructions say to expose for @20 iso in full light and @12 in shadows or cloudy etc. This is perplexing to me, since we were saying that the best for full range of tones is to overexpose and underdevelop, so rate at 12 and develop for less time... Then developing instructions are saying that "initial temperature at 23 C°", since it will get colder during development... But in tempered areas of the planet, from 23° it can get HOTTER....! In any developer, times are given for 20 C° , to be mantained. Results: it is very difficult to replicate same development/exposure combination. Do you have any suggestion? Thank you

Hi, wonderful review of this film. Could you give us some details of Greg’s setup for copying. After reviewing your previous video on scanning, my budget really doesn’t allow to purchase a single use item but copying using a digital camera with a macro lens seems the right direction. I’m interested in the bellows, extension tubes and holder setup since they can certainly be used for macro work. Thank you!

[@ianthomas465]

Hello Dan. My setup was a Pentax K1 full frame DSLR. From the 80ˋs I still have an original Pentax bellows with slide copy adapter (I used it for drawing b&w-negatives from my Kodachromes). The lens that I use is a SMC -TAKUMAR 50mm f 4 macro-lens. Pentax recommends to shut the aperture to f 5,6 and that works quite well. Cheers, Greg

[@MD-en3zm]

I love the results, but want to find a cheaper developer for it. I’m looking at TD-3 which was designed to tame contrast in technical/document films like tech pan. Have you found any developers that have worked decently well and were more affordable? Also considering POTA, but the Troop and Anchell book recommends TD-3 over POTA (supposedly Troop actually developed the formulation and it’s based on glycin). I’ve ordered some TD-3 (it’s not expensive - one pack makes makes 40 liters or 5 gallons for 30 dollars). If it works, it could make this beautiful film affordable enough to shoot often.

[@Walkercolt1]

The old Kodak Technical Pan could resolve over 350 lines per mm when processed in several Kodak high resolution developers. I can't help but notice ADOX doesn't even CLAIM a resolution figure, so is it AS SHARP as Kodak Technical Pan (still available as a Special Order item)? Kodak 35mm Kodalith Type 3 is capable of >335 lines per mm when processed in Kodalith Fine Line Developer and both are common as dirt. Since ADOX CMS 20 II Pro and ADOTECH IV STILL (22/03/29) aren't available to me in the US, personal tests aren't possible. The film alone is available to me, but not the requisite developer. I have made THOUSANDS of 48"x 60" "poster prints" from both Kodak Pantomic-X and Agfapan 25 B&W films when I worked for a commercial photo-lab-both grainless.

Thanks for your comment. Good point. We eventually scanned the one with one stop of additional light just because it was easier to scan it. The normal exposure would have been fine as well.

[@LentusFlentus]

It is an amazing film. Comes at a fairly low price. I definitely recommend shooting it. Portrait results are very interesting as well. :)

One can shoot this film with gorgeous results by rating it at ISO 60 to 80 by developing the film in the H&W developer, a formula that you can get on the web!

[@jasonzy425]

The sharpness and grain remind me a lot of tmax100 for some reason, the sharpness of which looks comparable to my eyes,

[@henningserger7150]

I have tested both films side-by-side under absolutely identical conditions in my test lab: Resolution values of CMS 20 II are almost double of T-Max 100. CMS 20 II is much much sharper, and also much much finer grained. You really see it immediately with optical prints. Here you are of course facing are the digital limitations (resolution loss because of scanning, extremely low resolution of computer monitors). It is impossible to demonstrate the real outstanding performance of this film in total online. You have to see it live and directly!

[@juancarlosguzman2827]

That is really a fine grain almost look like digital image

[@seymourjackson9777]

Wow

What fixer and stop bath did you use with the adox developer? Did you rinse in between steps?

[@JenniferM13]

Wish I could find this film in 120.

[@taraz3d]

How does it compare to TP2415@25 ISO + technidol ? I still have my FM2...

[@henningserger7150]

I have used Technical Pan in the past, and I am using ADOX CMS 20 (first version) and now CMS 20 II regularly. ADOX CMS 20 II offers much higher resolution, better sharpness and significantly finer grain than Kodak Technical Pan. But Kodak TP had a higher sensitivity (higher speed). Another difference is spectral sensitivity: Kodak TP was super-panchromatic (higher sensitivity for red), and ADOX CMS 20 II is ortho-panchromatic (lower sensitivity for red, red is rendered darker in the final picture).

Please make a review of the nikon f6!

[@sandor7594]

Check out: Antonioni movie: Blow up! Nikon camera with Kodak BW film .. For me a ORWO NP15 film with Carl Zeiss Jena Tessar 28./50 lens gave the best results so far. It would be a shame to underestimate the GDR technique because it also competed with the best Japanese technique in this field. But for civilians, the best lens is the Pentax Super Takumar, and Ilford FP4 Plus film

Does anyone has samples photos of ADOTECH IV and Spur Ultra R 800 Film combination?

[@jw48335]

Great timing! I was just digging into this in an effort to determine the limits of 35mm print sizes. You may find this interesting - google "More Ultra High-Resolution MTF Experiments Roger Cicala". That will give you the lens list that can truly produce the best results with ADOX. For example, the highest resolution "normal" lens is the 40mm Sigma Art, which achieves over 200lp/mm, and the highest resolution portrait lens is the Sigma 105mm Art, just barely making it to 240lp/mm. If ADOX really goes to 600 or 800lp/mm, these lenses are the best currently to push that. I am wondering what an ADOX negative shot with one of these lenses and scanned with a Sony A7r4 pixel shift 240mpx image would look like. If you google "2007-04-vitale-filmgrain_resolution", that will get you to an excellent research paper covering the resolution of many still available films such as Portra 160 and Tri-X, what they can resolve, what they typically resolve with good glass, and the impact of grain on resolution. Great video and thanks!

Regarding your last reference (2007): The math is good but the measuring is deficient. Very common in small scale/newbie/amateur science. It’s been proven imperically over and over that films real attainable resolutions is higher than the numbers cited. Just do a casual Google. As usual in these kinds of tests they commit the mistake of thinking the scanner tells the truth or that you can somehow glean the truth even through a bad scan. Low res/bad scans are exceptionally deceptive. They “somehow” have a way of bewitching the people doing them into thinking they are “good enough”.

[@jw48335]

@@Frisenette While I don't disagree, the document does provide relevant information on several films regarding what the manufacturer states as the resolution the film is capable of. My conclusion was that the limiting factor will be the lens. I'd rather carry a Pentax 645N if I need the larger print sizes than carry around a 40mm Sigma Art.

[@Frisenette]

@@jw48335 the data sheet can be very misleading partly because it’s too honest (in a way digital manufacturers has long since given up on (have you ever seen the MTF chart for a sensor for instance?) and partly because it takes experience and knowledge to read. For instance negative film was never meant as an end medium, but merely as a data transfer medium to another substrate. As such micro contrast and ultimate resolution is made for that.

[@henningserger7150]

I am running an independent photography test lab. And over the last 30 years I have tested almost all films on the market, and the current digital sensors. By far the highest resolution I have ever got in my numerous tests is with ADOX CMS 20 I / II. With that film I have reached the diffraction limit (physical resolution limit) of my best lenses, e.g. for f5.6 that is 240-260 Lp/mm. Impossible with digital. Carl Zeiss has used this film for their resolution tests as well.They have got at f4 the diffraction limit of their test lens of 400 Lp/mm.

[@jw48335]

@@henningserger7150 Interesting. I recognized your name from the reading I'd been doing :) Thanks for sharing!

[@northof-62]

I wish we had an film camera with a sensor that replaced the pentaprism. Then we could pre-evaluate the exposure on a rear screen before comitting the image to film. We could then do tricks like filling the image with light until we were happy with the result, a feature Olympus has in some of their digital cameras. I would call such a camera DSF - Digital Sensor Film camera.

[@karellen00]

What you want has even been done by sony, but with digital cameras. Early sensors didn't have live view capability, so they designed a pentaprism, really a pentamirror, where one of the five mirrors could open revealing a second smaller sensor that captured what was impressed on the focusing screen and transmitted it to the screen as a live view stream. It has been used with digital cameras only, but it could work with film too, and you would still be able to use a traditional viewfinder too!

[@northof-62]

@@karellen00 Yes I remember the Sony. I would just put a sensor above the mirror and not complicate things too much. EVFs today are pretty good. Even the one I have attached to my now old Panasonic GX-1 is size-wise on par with any full frame DSLR or SLR. But you could of course just take a digital shot electronically before you slammed up the mirror and exposed the film.

[@robifleming]

Wow! It does look like it’s coming out of a monochrom Leica camera.

Thank you. 👌 Kodak Technical Pan, but significantly better. ☆☆☆☆☆
