Gotta say the new oly om-d was very nice to use, especially with a grip.
But I have 11 ef mount lenses, 3 eos bodies, 2 ex flashguns..
The a7 may well be great, but I'm sure canon will be along with something close or better, soon.
I can't afford to blow with the wind, or run multiple systems. Where I need something and I can't buy canon I buy something else (tokina f2.8 uwa is a requirement for vidro and a product unique to tokina in aps-c, my gopros are pretty much market leaders, canon don't make comparable, my sennheiser mics etc) but for my purposes the a7 isn't a game changer. The 7d was (first PAL switchable video dslr, first DSLR with full manual video exposure, the required 5d2 firmware came after I bought my 7d) the c100 / Ninja Atomos 2 combo may be. The Sachtler ace is (at pricepoint at least)
Long term 135 format DSLR users have never really engaged in aps-c or rebel bashing. Since the 5d2 but particularly the 6d came out there seems to be a lot of folks who are queing up to kick aps-c.
Maybe the price of the 6d is low enough to let the riff-raff into the 135 format dslr club.
A bit like social climbers or lottery millionaires, they might dress the part but reveal their lack of etiquette, lack of manners, lack of class the second they open their mouth "i don't know why everybody doesn't drive a mercedes" type of thing.
APS-C is dead.
Long live APS-C.
Enjoy the school sportsday.
