Angenieux are still a leading company making lenses for the motion picture industry as well as specialist industrial and military lenses. Alpa never made their own lenses but used lenses from some of the best manufacturers of the day including Angenieux and Kern (who were also well respected in the cine field). I have seen some pictures taken with a couple of Angenieux lenses of the 1970s on an Alpa and from memory and in my opinion they were every bit as good as could be achieved with the best Leitz, Zeiss, Nikon or Olympus lenses of the time. Again, from memory they were erring more towards the Leitz softer contrast rather than the harder contrast of the Japanese lenses. I can't remember which lenses these were precisely by I was impressed at the time (1980s) so I would recommend you try the lenses out.
