When I was working in the photo industry in the late 90s and early 00s, Nikon was king. Canon was already a close second or even considered the leading brand, depending on which photographer one spoke with. Both companies offered a robust selection of lenses, advanced camera bodies, and excellent autofocus systems. And then there were the outlier brands, like Minolta, Olympus, and Pentax, all who made some wonderful cameras, but were not nearly as popular as tools for professionals. Minolta was, perhaps, one of the most adventurous camera makers.
