Sony has introduced the A6600 today. The specs indicate that the A6600 is an excellent camera but, it doesn't bring enough to the table for me, to switch from my combination of A6400 and A6500 for tandem use.
IMO, the specs of the A6600 are what SHOULD HAVE BEEN INCLUDED IN THE A6400 FOR STILL PHOTOGRAPHY but, were lacking: IBIS and larger battery capacity. No 20 FPS, no 1/8000 second shutter and no mind blowing improvements in AF and of course, no global shutter but, that last was reaching for clouds...
It just goes to show you how much I expect from Sony when you see me looking down my nose at a set of really excellent specifications just because they have not brought what I wanted to the table for still shooting...
Yes, I would prefer the A6600 over either my A6500 or A6400 but, no, there is not enough advantage in the A6600 to convince me to switch. The change of battery is a great idea but, the A6600 doesn't offer me enough extra options to start using a camera set with two different batteries. I learned my lesson along that line in 2004 when I was shooting with a Canon 10D and a 350D. I ended up down at the bottom of Carlsbad Caverns New Mexico with a dead 10D battery and only 350D batteries with me. The choice was shoot with a single body or return to the surface and go down another day because it would have been too late to return to the bottom that day. Mia Culpa, of course but, that was the last time that I used a set of cameras with two different batteries.
I am somewhat excited over the new Sony APSC lens, e 16-55 f/2.8 G, however, sadly it doesn't appear to include OSS. Sure most of the Sony bodies now include IBIS but, OSS would be a great improvement to that lens. Sony has needed a really good APSC zoom lens in that focal range and f/stop forever now. If the IQ is decent (which we cannot count on from a non G-master Sony zoom) this will be a great addition to the Sony lineup of APSC lenses. Pretty hefty price tag but, we have come to expect that from Sony...
Will I buy one - I seriously doubt it because of the steep price tag. If I want top-notch IQ from my Sony AOSC cameras, I will stick with some very good prime lenses...
