"So I went back to Canon and Nikon’s recent published numbers and the CIPA shipment numbers for 2014 so far and plugged them into a spreadsheet with Sony’s claims and an assumption about Sony’s DSLR sales (which they didn’t disclose). What I came up with was a range of values that went like this:
Canon — 38 to 40%
Nikon — 33 to 35%
Sony — 12 to 14%
...But, overall, it looks to me that we’re still locked into the same basic pattern for unit volume in interchangeable lens cameras that we’ve had since the early 90’s: Canon leading, Nikon following, and Sony (originally Minolta) trailing. At the moment, there’s nothing appearing from any of the three that seems to be going to alter that any time soon."
