First of all, the Tasma film originates from Russia, and is described as a b&w motion picture film. The Russian site says that the factory dates from 1933, so Tasma has a long history. The film is on a PET base, not acetate, and consequently is extremely tough and will not tear like an acetate-based film. It's also thinner than typical 35mm films, much like the Svema stocks that I have used, but seems not as flimsy as the Svema. The Tasma NK-2 film is fresh stuff, according to the FPP site, and has a sort of cult-status.
The Tasma NK-2 rolls are in 24-exposure cassettes from the FPP, and are DX-coded. I would prefer 36-exposure rolls, but then again, with these limited-availability films, the shorter rolls are a good idea, especially for testing. The film loaded easily onto the take-up spool in the Nikon F3HP and the Yashica FX-7 cameras that I used. I set the ISO on the cameras to the box speed of 100.
I checked the Massive Development Chart, and the information on the Tasma NK-2 seemed rather odd, so I consulted the FPP pages on Flickr, and found two developers that I use: D-76 and XTOL. Leslie Lazenby's recommendation was XTOL stock at 7.25 minutes. Another photographer (Tom Napier) recommended D-76 straight for 7 minutes. I find the MDC listing a bit odd, as I have only seen examples with people shooting it at box speed.
Other developers and times that I have found (all at 20°C):
HC-110 B for 10 min
D76 Stock for 10 min
Diafine - 4 min each in A & B
I developed in D-76 for 10 minutes, and did a water stop, followed by 7 minutes in fixer. I washed in water and used Permawash to remove any fixer followed by a good rinse. Both rolls came out beautifully. The film dries perfectly flat, and scans beautifully on my Espon V700.

Yashica FX-7 Super with 50mm f/2 lens.
Overall, the Tasma NK-2 is a very easy film to work with, especially now that I have a developer or two that I can use to get satisfactory results. The tonality is certainly acceptable, and it is fine-grained. I can see no reason why anyone would not want to try some. The fact that it scans so well should be a key point in using it. I think a bulk roll of it from the FPP store is next on my list.
