Yes, and quite deliberate. If a case can be made for a professional APS-C DSLR and the professional user needs more than 10FPS, then a case can be made for a professional APSC MILC. My 7D tops out at 8FPS because that has proven fast enough for my needs.As you see it, the ‘professional APS-C mirrorless market’ has little or nothing to do with the presence or absence of a mirror. Seriously, that’s a textbook oxymoron.
Those arguments also apply to FF professional cameras. Are you planning on keeping your 1Dx forever?A mirror means an OVF, no lag for tracking a subject, no constant drain on the battery to look through the VF. Perhaps you should ask ask all those photographers who make money with their 7d2 and if they think a mirrorless camera would meet their needs as well as their DSLR.
Pot, meet kettle.Do you think puerile name-calling like that adds value to the forum? All it really does is demonstrate your immaturity.
