That is from a survey from a site called ITMedia. It could be not representative, depending on who voted. For example, I've never heard of the site. What if they posted the poll, then went to all the Pentax-centric forums around the web, pointing to it, but not to Canon, Nikon, Sony, etc.? If this is not the case, wouldn't it be impossible for Pentax/Ricoh to not to also be best-
selling?
Let's get to that, then. When it was time to actually BUY, the winner was Olympus. (
Source) In fact, four of the top ten were Olympus, and that includes 1st and 2nd place. 1st and 10th place are the same camera, same kit, but just different colors! I wonder if it has something to do with Olympus' sale to JIP, and people wanting a piece of pre-JIP Olympus history...
It will be interesting to see how it shakes out for 2021.
