So finally the Sony A9 has been announced. Twin card slots, better battery, blazing fast 20fps. Priced like a 1Dx/D5. Whats everyones thoughts on it? Also, a native 100-400mm solution announced for FE mount. THAT is of interest to me but the pricing is going nuts on the lenses. I imagine as this is a GMaster, then it is going to be pricey! Really want a 400mm solution. What do you guys think? Evolutionary or Revolutionary?
