Konica lenses are pretty great. They are every bit the equal of Canon or Nikon, just not as prolific. Their medium-format optics are much more well-known and liked (the Koni-Omega system).

I've got a stock of their Color Professional 160 film. It's not actively bad but is generally underwhelming compared to the latest film stocks.

Similarly, I'm a big big fan of Fuji lenses. Fuji did (does) a godawful job of marketing their wares in the Western markets, so they don't have the reputation of Schneider/Rodenstock, but the lenses themselves are great. Even today Fuji is really awful, half the time your first notice that they're discontinuing something is when everyone runs out and then two weeks later Fuji announces that there won't be any more.
