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.

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.

Surprise that they didn't add OSPDAF & image stabilization in GRII.
Anyway, I love my GR very much, not planning to upgrade any time soon.

In reply to:

Daniel4: I sold mine because it caught dust on the sensor twice, even though I carried it carefully in a plastic bag. If the GR II were dust sealed, I'd buy it again.

Ricoh GR does not have a front glass in front of the lens,
therefore when lens move, it suck in dust.
The problem can be solve easily, by adding a 32mm filter/protector in front of the lens.
You can easily find one for GR in ebay.
Mine put in jean pocket all the time never have problem. :-P

Roy LaFaver: Considering the IBIS and BSI in this camera, I don't see how we can even think about a list of cons. This will an amazing camera. The a7ii is plenty for me, but it is nice to see something like this beauty.

Con:
Poor battery life.
Tiny grip
Poor balance for heavy lens
Overheat during 4k video
No native F2.8 zoom lens
No dual card slots

Link | Posted on Jun 12, 2015 at 10:00 UTC

Put it in A99 body, a-mount
higher burst rate 8fps / 10fps,
larger buffer, dual card slot,
Able to put 3 large batteries at once with vertical grip.
No overheat during 4k video
Then Sony you will take my money. :-)

captura: Much too big, and I don't need full-frame. When will Sony finally give us a NEX-7 upgrade camera?

The camera is too small, battery life is poor, only got single card slot, not support UHS-II
When will Sony finally give us a A99 upgrade camera?

In reply to:

Rooru S: DPR Team. Any comparisons between the AF performance of the A77M2 and the A6000 both with their respective 70-200 G lenses??

I guess the AF performance will be similar if there is enough light.
But when the light level drop, A6000 will start hunting,
while A77ii can still keep focus.

ESUELDO: I am using canon 70d with canon 300 mm f4 with tc for BF, I have sony a600 with 70-200 g and I liked both settings, I am wondering if I would buy the sony a77ii for wildlife, in that case with lens do you recommend , cost is important

I recommend Sony 70-400G2 or Tamron 150-600 for BOF
I had the 70-400G1 which is a great lens, now I am using Tamron 150-600.
The 70-400G2 will be AF faster & tracking better than G1

In reply to:

TxDad25: We've been using the SLT A57 since early 2013. We use it primarily to take photos of my son's basketball games. While we're generally happy, it does have some minor issues. That said, I'm pretty heavily invested into a-type lenses.

I'm ready (I think) to move to something more current. I'm curious if it makes sense to upgrade to something like the A77II, or to divest myself of the a mounts and move on to mirrorless. If I should upgrade in the DSLR space, is the A77II a significant enough improvement on the A57 to justify the cost? I've also considered jumping to Nikon, though I'm not sure if I'd gain anything there.

All thoughts or opinions are appreciated.

Lots of us were upgraded from A77mk1 to A77mk2.
And I can honestly tell you that it is a significant improvement compare to A77mk1 & it definitely worth the upgrade.
So, if you are upgrade from A57, I am sure you will be happier than us.

@DPreview,
On Page 7.Operation & Controls -> Auto ISO
The MFNR you described is not correct.
In A77ii it does not just combining 3 frames of images.
The Mutli-Frame Noise reduction in A77ii have two setting,
With setting MFNR (High) it combine 12 frames of images.
while setting MFNR (Low) it combine 4 frames of images.

In old A77 Mk1, there was only one setting in MFNR,
which combine 6 frames of images.

You can check the "sequence length" value in EXIF data of the image

With the help of the faster processor Bionzx in A77ii, the MFNR processing time has been shorten a lots as well.
