Which camera is better, Olympus or Nikon?

Olympus and Nikon are photographic equipment companies with a long history, both of which have produced classic film SLR cameras and excellent lenses in the film age. In the digital age, Olympus joined the M43 camp, and the sensor format is small (only 26% of Quan Huafu's), which limits the film quality. Nikon digital SLR has been transferred from APS-C(DX) format to Quan Huafu, and its Quan Huafu SLR D8 10 and D850 are unparalleled in image quality. Comparatively speaking, Nikon has more advantages.
