If total market share is important to you that's fine. I don't see how that's any more relevant to meeting my equipment needs than knowing which mega-corp sells the most cheeseburgers or shampoo. But, if going along with the crowd makes you feel warm and fuzzy then that's what you should do.Tell me again about when Sony passed Canon in terms of total ILC sales and ILC market share. I seem to have missed that announcement.
Canon's market share is inflated by sales of consumer camera's that don't really interest me. Canon can put t7's in crackerjack boxes and McDonald's Happy Meals for all I care. I judge camera's on their technical merits and ability to meet my needs, not their popularity.
edit: The relevant point I was trying to make is that everything Canon has done in the last five years has been in response to pressure from Sony's Alpha's. Despite being the market leader in sales, when it comes to tech they are following, not leading.
Does anybody believe Canon would have released the R bodies and RF lenses were it not for Sony's Alpha series hogging all the positive press for the last five years.
