lhkjacky: It seem Sony A99mk2 just fixed all the cons in 5dmk4.

42.4MP BSI FF sensor, 12 fps, 5-Axis IBIS,
399+79 point Hybrid AF, AF sensitivity up to -4EV, Eye AF
4K MPEG 4 AVC/H.264, Slog2/Slog3, Gamma assist,
Full Tilt and Swivel Articulating LCD,
EVF, Peaking, Zebra pattern, Clean 4k HDMI output,
Slow~Quick Motion, 120P in Full HD.
Highlight-Weighted Metering,
Spot-metering link to focus area,
Shutter Life Expectancy 300,000 cycles
WIFI, NFC, Bluetooth

According to Dpreview the 5dmk4 cons are:
● iTR subject tracking lacks precision & reliability
● iTR optimized for erratic subjects can lead to mis-focus
● No way to link spot metering to chosen AF point
● 4K video limited to Motion JPEG
● 4K/30p video requires CF card
● 4K video comes with a crop factor
● No Log gamma,
● No focus peaking,
● No zebras for video
● Fixed screen limits usefulness
● HDMI-out limited to 1080 video

69camaroSS: This thing is going to be awesome for video! full-frame 4K. Think of the DOF options that won't be accessible on anything else besides the E mounts. And you'll actually have a big enough battery to use it. If the AF system is on point, Sony has a winner. This could be the new Mk2 for filmmakers.

A7Rii use a tiny battery which is designed for the tiny nex camera.
On the other hands, A99mk2 use a standard DSLR battery, which has been used in all A-mount DSLR/SLT.
The capacity is almost double over those tiny battery.

Nukunukoo: Dual Phase Focus (one from the translucent mirror and one on the sensor) is an extremely effective way of getting really fast focusing speeds. Along with a combination of contrast fine tuning, I'm surprised it didn't go like -5EV.

A99mk2 is -4EV at F2.8
which is 1 stop better than 5dmk4
and 3 stop better than A7Rii

EXX: Great specs! But why no pop-up flash? A pop-up flash can be very handy as a last resort or as wireless controller.

What is next, an A88 budget version, with a 24 MP sensor similar to the A7II sensor?

To be honest, I have never use the pop-up flash in my A77 & A77mk2
If I need flash, I always use external flash which allow to bounce or add a large diffuser.

A99mk2 focus point sensitivity at low light is 3 Stops improved over A7Rii
A99mk2: EV-4 at F2.8
A7Rii: EV-2 at F2.0
A7Sii: EV-4 at F2.0
Canon 5D mk4: EV-3 at F2.8

iae aa eia: I've seen some nice line of cameras ending with great final products and leaving people like "Aaaah..." and "What? Nooo!" This one seems more like that is the case. I so no point for a SLT camera anymore. Sony has gone too far with mirrorless already. This may be part of the investment plan of the A system, which do not include only leaving owners of the A system accessories orphan when they ended camera developments, but also owners of Zeiss lenses. Maybe, there's nothing to do, but the fact is that I've seen nice lines end bossy like that.

If you shoot sport or action, mirrorless AF is not good enough, especially using long telephoto lens or under less than optimal lighting.
Sony engineer has keep saying that OSPDAF in mirrorless camera has it own limitation because they are so small. For long telephoto lens, dedicated PDAF is prefer, that is the reason why they promise to keep developing A-mount camera.
SLT is unique product, it combine the advantage of both EVF & dedicated PDAF.

PanchoVilla: Is the Alpha line up even still relevant? Sony is all over the place throwing whatever sticks on the wall! Nice camera if it was 2008!

My A77mk2 has over 600k shutter count already and still working perfectly.
No sign of any wear off yet.
Hope my A99mk2 or A77mk3 will arrive before it dead.

JoeDesperado: Dear DPR staff, could you please elaborate on the AF performance (and its limitations) when using A-mount lenses on the A6300 via the LA-EA3 adapter? I had to find out the hard way that the praised AF tracking options like "Lock on: expandable spot" and even the "zone AF" mode can't be selected when using this combination, which is a major letdown and is nowhere clearly stated by Sony or any review I read so far.
Here's a link to my findings: http://www.dpreview.com/forums/thread/3976376

As usually, no reviewers care about A-mount.
Sony don't care about A-mount either.
Everyone just want to know how the Canon lens works on E-mount.

At the product launch, Sony said they put the universal AF feature of A7Rii into A6300, so no surprise they both work similarly, and have the same limit.

May be Sony will provide a firmware update later.
But I guess they will apply it to A7Rii first. It is their $3200 flagship camera. How can a $998 camera get better feature than the flagship.

Len_Gee: Does the MKII finally fixed the dust in lens issue that plagued the original GR?

Just get a 32mm filter/protector from ebay, it prevent dust from entering from the front of the lens.

I always put my GR mk1 in the dusty jean pocket, used over a year no dust in the lens.

Personally, I prefer using DLSR/ SLT, rather than the poor battery life, small e-mount camera.

The AF of my A77ii is still lots better than the A6000,
Interesting that Sony also admit that A6000's AF is only good enough for a holiday camera.

And A7Rii's AF is also not as fast as A6000, it is not surprise because Sony use hybrid AF, they use CDAF as the final state of the AF, APSC with small aperture zoom have wider DOF which help CDAF focus faster.
(Same reason Nikon 1 can CDAF faster becoz smaller sensor have wider DOF)

For large aperture zoom or long focal length telephoto lens, OSPDAF have difficulty to find focus at completely out-of-focus situation.
So DSLR / SLT is still better for sport shooter or demanding AF situation.

IMO, Sony should keep developing a-mount body with the unique SLT design.
It should have larger body, longer battery life, and ultimate AF ability.

"if we just did the same thing as Canon and Nikon we’d lose".
This was the statement that they told us, when they stopped making OVF camera.
SLT is a unique camera, it is something that Cankon does not have.
SLT combine the advantage of DSLR's level AF + EVF.

Everyone talking about A7Rii, because it have a new 42mp sensor, world first BIS Full Frame sensor, 4k video in FF, 5-axis IBIS, etc.

If they put this new sensor & technology in A99ii first, everyone will talk about it as well.

lhkjacky: IMO, Sony SLT design is the best,
It combine the advantage of both world,
DSLR's level AF at low light + the advantage of EVF.
It remove vibration from the mirror flip completely, at the same time it remain excellent AF tracking ability of DSLR.

I understand that some people may like a tiny camera like RX100.

But personally, the ergonomic grip & longer battery life is a plus not minus.
90% of sport shooter use 1Dx & D4s, unless Sony can make a mirrorless 300 F2.8, 500mm F4 small,
I don't think camera body size a problem for me.
But it is just my personal preference.
