Now I'm really confused.

I needed another camera for certain shooting situations since my E-M1 really does not do great continuous Autofocus (though it's pretty darn godo in other ways). So I was thinking of the upcoming A77ii. But now I see the A6000 has virtually the same specs. Same APS-C, almost same frame rate, and (maybe?) same continuous autofocus capability.

So what's the deal here? The A77ii is almost double the cost of the A6000.

Can someone please explain? What's the dif?

  • Bigger body, more materials.
  • Better build quality with weather sealing.
  • IBIS.
  • Higher resolution EVF.
  • Better LCD screen (RGBW vs RGB).
  • LCD screen has more articulating points.
  • Dedicated PDAF sensor allows continuous AF even while the shutter is in action.
  • Higher frame rate.
  • More buttons, dials, and inputs.
  • Faster max shutter speed (1/8000s vs 1/4000s).
  • Greater flash sync speed (1/250s vs 1/160s).
  • More powerful built-in flash.
  • Probably a longer shutter life (150,000 vs speculated 100,000).

There are probably a few other things I am missing, but this is a quick run down.

Thank you.

What does this mean: "Dedicated PDAF sensor allows continuous AF even while the shutter is in action"?

Hi Corrpy - what it means is that the PDAF sensor in the A77II is separate to the imaging sensor - it works from the light refelected by the SLT mirror whereas the A6000 is using the iamging sensor itself.
So when the shutter (not shutter button) is used the A6000 has to have a break (like a traditional camera would but for different reasons.
As the A77II is using a different sensor the shutter has no effect on it.

Thank you. That's certainly a detailed response. But in practice, what does it mean to someone who wants to shoot continuous at high speed of moving objects? Waht is the final difference based on what the a6000 is and what the a77ii is spcced to be?
