I just recently saw that. Might need a vacuum pressure plate, though!

Why??? It was grainy as hell at 3200. The real ISO is 1000. Even Micro 4/3 cameras are better at 3200, and they give you color and/or B&W.
Thirty years ago I did not realize that the true ISO for a normal rendition with this film was much lower than box speed. I exposed it at 3200 and the results were not terrible but it depended on the developer.
I recently tested Ilford Delta 3200 and it measured close to ISO 1000 in Acufine. I expect similar results from TMZ.
Both films would be satisfactory for medium format.

For 24x36, probably a much better lens than most of us can afford. Beyond a certain point, the lens is the limiting factor for resolution
The only solution is to move up medium or large format and then the resolution becomes less important than the film speed.

Oh but are the dates on the film still in date or have they been just stored in a freezer who knows where?

I posted a two-part article three years ago on the Online Darkroom:
Adox CMS 20 II - adventures in development and
Adox CMS 20 - adventures in development Part Two in which I showed how I was able to develop it to a normal contrast.
What I found was that it is difficult to nail down an ISO and development method for a film like CMS 20 II (Rollei Pan 25 is similar) because the high resolution can easily produce a very high contrast. I ended up having to resort to compensating development and a very high dilution of HC110.
It's possible but barely worth the effort.
