What do you mean by 'converted'? Those companies somehow modify the emulsion of a film that's already coated??
IMHO this issue is typical for R80S, R400S, SP200 in the 120 format. In 135 format it is rare. The R400S, the SP200 and the Infrared 400 are converted from the same masterrolls, produced by AGFA as Aviphot 200. The R400S and the SP200 (and R80S) are converted by an east european company and Infrared 400 by a brtish company. I never had the black dots on IR 400, but I had them on the other films. The 135 format of R80S, R400S and SP200 is of a much better quality. But the 135 IR400 is of a superior quality.

im not so sure. Ive shot hundreds of rolls of the 200/400 and 80 rolls both in 35mm and 120 and never had any of these issues. hopefully its a one off event and going forward its not an issue. funny, maco refunded and replaced every other person so far who had the issue but told me sorry, your out of luck. sucks to be first to report a problem. -(
So would I understand correctly that SP200, R400S and IR400 are in fact the same emulsion? If so, I wouldn't mind paying a bit extra for IR400 if I can avoid these issues.I shot some hundreds of SP200, R400S and abot 100 of R80S in 135 too without "real" issues. But in 120 format I did have a lot of trubles (maco refunded and recommended IR400 to avoid the issues). For the IR400 is more expensive than the other films I buy 5 rolls of R400S every 6 month an do some test. The results show the IR400 is of a superior quality. I still hope the quality of R400S, SP200 unsd R80 in 120 format will increase.

I've had the same spots on Superpan 200 in 120 format. It was not stored differently from my other films which have never been like this. My storage is cool and dry. Wrote to macodirect. No answer. I'm byuing no more of this film.
Contamination.shouldnt be difficult finding out.I had this issue a few weeks ago with brand new Rollie retro 80S film. this is the new batch in the cardboard boxes, not the older plastic cigar style holders (which I really like). I sent this scan off to someone who knows the rollei films very well and asked his opinion. He replied "this does not look good, it looks like a backing paper issues" I trust his opinion and sent off an email to maco. I got the typical response fomr them, that it is my process that is at fault and im wrong. I even developed three different rolls of film at the same time with the RR80s, two of acros and now one tmax 100 and none of them had issues. also then did 3 more rolls, three different developers all with brand new one shot fixer and the entire process with distilled water. same issues. I had bought a bulk roll of RR80s in 35mm at the same time i bought the 120 rolls. So I rolled up a few rolls of the 35mm and had no issues at all with them. I wanted to keep this quiet until I knew it was something that i did or didn't do as I didn't want to point a findger at someone who did nothing. After getting blown off by maco I posted the shot in the flickr RR80s group and within a week got 4 others who had the exact same issue. anyway here is what I posted on flickr......
not sure whats going on here. the grey sky has black dots all over. it is on every frame of the three rolls I shot. used the same camera for many other rolls and none had the issues. I then developed the last roll along with a roll of acros to see if its the developer but the acros was great and RR80 had the dots all over clear grey sections, like skies. and YES it is on the negatives as I used a high power loop to view and they are there, along with using a macro lens to to take a digital shot and zoomed in a lot. this is on the brand new batch i bough about a month ago, exp date 9/18. i have more rolls along with bulk rolls and im afraid the use them. sent an email to maco, but based on their past behavior, I really dont expect them to answer.
And here was Maco's reply to my email

Hello John,
Thanks for your inquiry.
I have discussed it with our specialist in the lab and from our point of view we are thinking that it is not a converting issue.
We can see these kinds of micro-grains, white on the negative, especially in the more middle homogeneous shades of grey.
It seems that there happened a creation of air bubbles or air pockets which were not shaked of the emulsion after filling the tank.
We have the "problem" that PET films with some developers provokes a kind of sparkling effect (similar to a fizzy tablet). A pre-washing could help as well as a strict pitching of the tank on the table (perfect before every tilting).
We have neither changed the film emulsion nor the converter. Ilford is converting for us the Retro 80S 35mm, not site 120. The only changing were the backing paper from a black one to a white/green one.
And now we are using triplex foil and a carton instead of our plastic rollfilm container. We are still selling this batch."
So if Im not the only one with this issue, and there is only one company left, if I remember reading correctly that makes the backing paper, and Kodak has an issue are we in trouble? I was particularly interested in the quote that we changed the backing paper, in a similar way to kodak changing theirs. dont want to cause concern but Im feeling like there is a reason to worry. I re scanned the neg, same issue. Used 3 different loops, same issue. printed the photo with 3 different enlargers, same issue.
Anyway thoughts?

I still have aviphot Pan 200 and 200S but 70mm. I also have a PEO, very thin 0. 06mm.very old. at least 20 years. Directly from Mortsel fabrication. if you could send me some of the involved paper i could cut down to 61.5m and testing/developping. but i will only reactivate my lab in 2019. i will get a pinhole-cam with 70mm back which has 120-option. Mamiya RB67/70 vaccum-back converted by vermeer(cameras). i could then expose the very same batch in the same cam with and without paper. i could also expose 61.5mm film with no paper or with 120 or 220lenght or whatever lenght in Roundshot. there will be a solution to mount longroll 61.5mm film in 70mm Kodak cartridges as a start. Linof may follow. not for all 70mm backs.IMHO this issue is typical for R80S, R400S, SP200 in the 120 format. In 135 format it is rare. The R400S, the SP200 and the Infrared 400 are converted from the same masterrolls, produced by AGFA as Aviphot 200.

Superpan 200, is this moisture damage or an emulsion problem?
