It would have been useful if they could show how DSLR unit and revenue sales have progressed since the introduction of mirrorless. They're using the "interchangeable lens" shares for headlines and it is inevitable they will eat into the existing share if they define it that way. Moving from counting from DSLRs only, to DSLRs + something else, the DSLR share can only go down by that calculation. The question is are they being bought instead of DSLRs, in addition to DSLRs, or instead of something else?
And are they really comparing the Pentax Q to a SLR?...
