Terkwoiz: So the mark iii is the best value for stills shooting right? Since it has the viewfinder and the following 2 models don't really change enough (stills-wise) to warrant an upgrade. Thoughts?

If you do not shoot video and moving target, why not get the Ricoh GR ?
It have a Sony APSC sensor and a super sharp prime lens.

gn28: Nikon needs to turn the Nikon DL24-85 into a Nikon DL24-100 m2... add the tilt and swivel touch screen of the Nikon DL24-500, a bigger battery (600 shots) and, ideally a 64GB fast internal storage (ssd cost around 20$) in addition to the SD card to support backup on the SD card which they can sell at 950$ and they'll wipe the floor with the RX100. I still own the RX100m2 but there's been little to no meaningful improvements since so I'm open to changing vendors rather than waiting for the RX100 IX which will probably cost 1800$.

PS: my apologies to the video blogers that can now record 4k instead of 1080p, which is nice. but other than for post processing option of changing angles, almost nobody out there will see the difference on their phones, tables, PCs or TVs.

@gn28, Please show me your Nikon DL-series camera, if you can buy it from anywhere on this earth.

Quote from Nikon News:
"The premium compact cameras, Nikon DL18-50 f/1.8-2.8, DL24-85 f/1.8-2.8, and DL24-500 f/2.8-5.6, will be delayed due to the serious issues with the integrated circuit for image processing built into the three new premium compact cameras"

When Nikon is still fixing the circuit bugs in their DL-series camera. Sony has come out a new RX100M5 already.
When the Nikon DL-series available in market, you may see the RX10mk4 already.
Poor Nikon. RIP
No surprise why they called their Action camera "Key Mission".

On article Elevating X-Trans? Fujifilm X-T2 Review (2178 comments in total)

For anyone require reliable AF in all lighting condition, dedicated PDAF is still so much better,such as D500. However, I admit that EVF is better than OVF in most situation. If a camera with the combination of dedicated PDAF and EVF will be perfect. :-P
Edit:
Oh wait, is the A99mk2 have both dedicated PDAF & EVF ?

Morvegil: Most sony users have moved to Mirrorless. Dead tech here.

The -4EV AF sensitivity are from the dedicated PDAF not those tiny OSPDAF on the sensor.
A7Rii share the same sensor, but it only have -2EV at F2.0.
3 stops behind A99mk2 (-4EV at F2.8)

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.

In reply to:

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

In reply to:

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

In reply to:

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.

In reply to:

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.
