More at B&H Photo The 24-70 f/2.8 and the 70-200 f/2.8 provide wedding photographers and event photographers with the two staple lenses. I expect these lenses to be sharp and extremely well built.   Along with the 85mm f/1.4 and the additional lens offerings like the Batis series Sony now has the lenses and the bodies to really start attracting professionals in numbers that should scare the pants of Canon and Nikon.  I am not saying this is all a perfect system - see my discussion of why I don't love shooting with the Sony a7RII at weddings but this does make the entire system much more appealing. I'd love to hear your thoughts and don't complain about the price- they are comparable to the Canon and Nikon offerings.More about the newly announced A6300.
