Like I said, advertising.
With olympus I knew what all 4 of their models were
With Nikon I know what D like cameras to go for and I know about their z mount lineup
With snoy I know what all their models do
But with fuji Idk what model is good. I know a bit about their medium format because I enjoy medium format cameras (although I dont own one).
Similarly not many people i see know much about fuji cameras. None of my friends are gearheads but some own cameras, and theyre all canon or sony.
