The Olympus K-series is a very interesting phenomenon, for several reasons. It's a good microscope allright, albeit depending on it's birthday. The earlier versions are troublesome, the later ones okay.
It's also one of those you won't find in the "official" historical Olympus microscope line-up. It's not the only one in that regard: Olympus has made quite some (semi-) toy microscopes as well, and you won't find those in the official records either.
The K-series came at a around the time when every microscope manufacurer faced the same set of problems:
1. shifting away from focussig trough movement of the tube and implementing focussing trough movement of the stage instead
2. an intermediary step (historically) in which the coarse focussing moved the tube, the fine focussing the stage. And
3. "coaxial" coarse-fine focussing using planetary gears.
The inclinable stand, with the horse-shoe shaded foot was only a memory at that time, but the focussing controls were still shaped after that concept..
The K-series was Olympus' lab. Once the research project led to result, they went further on. Some customers paid for it. Thats how things went. And go.
Olympus wasn't worser than others: they all did that kind of things.
