According "The frugal photographer" page, it is safest to assume a film should be used within one year of being removed from a freezer. I have used expired RSXII slide film; I bought it already expired from my regular provider but they assured me the film was refrigerated all the time, I also kept the rolls refrigerated - not in the freezer- and used them about four years after the expiry date, I did not perceive differences regarding results between the same films used before the expiry date and after the expiry date, anyway I don't use expired film if I'm not sure it was kept refrigerated or frozen from the expiry date or before it, the Plus X was an exception. > My 2nd question concerns the quality of the 5.6/500 mm lens for the SL66.

The SL 66 page says HFT is less important with lenses from 80mm to 1000mm because they have a few elements in comparison with wide angle lenses, HFT is very useful for the WA lenses with several elements, the original dual layer Zeiss coating already protected very well the lenses against flare, but HFT is an improvemet anyway, you could need it in some rare situation with the 5,6/500mm. A multicoated UV filter does not convert a non HFT lens into a HFT lens, this filter does not compensate this fact, after the light crossed the filter it still needs to cross the lens and the lens is not multicoated.
