Three-week test, Conclusion: whining at a high level - actually 4.5 points (### update 12/15/2014 ###)

I have the A77II now since about three weeks in use and would therefore like to talk about my experiences.
Besides the Sony "kit" lens 16-50 I have tested the camera with a Tamron 70-200 2.8 and a Sony 18-250.
As a comparison, the cameras a6000 served with the "better" Sony 18-55 lens and the Tamron 18-200 (and also a RX100M2).

Of course I have no laboratory tests are conducted, but reports only from my experiences. However, I have not the same after two days written a review, but treated myself to three weeks extensive test time and certainly shot> 1000 images.
I now want to write no further large text, I collected my impressions so far as facts - I hope this helps.

For questions (and comments) will be happy report via comment!

First the negatives:

- No more GPS
- No apps installed such as in the A6000
- Do not load the batteries in the camera via microUSB (even in relation to the A6000 / RX100M2)
- 12fps mode only via the mode dial, the remaining series options but then again via menu
- Noise due to the SLT technique slightly higher than APS-C standard
- In low light, therefore, not particularly strong, the roars A6000 at ISO 1600 as the A77II at ISO 800 - but still good (who wants LowLight accesses VF)
- The drive is not accurate to use or bit fiddly / getting used to
- No 4K video (would actually be possible to see RX100M3 vs. Panasonic Lumix FZ1000)
- Mode dial has a twist - first press button, then turn. With such a camera rather unnecessary (in the RX100 that would be much more useful!)
- Does not seem to benefit from fast memory card - the memory bus is probably slow, but the buffer itself is quite large

Now for the positives:

- The OLED viewfinder - really a killer feature that I do not want to miss. As can keep no optical viewfinder!
- The AF is really very quickly and accurately, the AF tracking adjustable in 5 steps, and seems to work really
- Excellent detail reproduction (of course only with ordinary lenses)
- Feel (great for larger hands!)
- Very valent, splash-proof housing
- Many configurable buttons and front and Reardrehrad
- Fold-out, rotatable display with excellent image quality
- WiFi for the transmission of images and (limited) control with smartphone
- LCD at the top (illuminated) - fast all the important information at a glance and Oldschool Feeling ;-)
- Very high burst rate
- Excellent "kit" lens
- Electronic level (2 axles)
- SLT as "real" Live View on LCD panel and viewfinder (incl. Stabilization)

Other info:

- The AF Assist Lamp: Yes, it's gone. But it can be replaced by the flash - and then works in my opinion better than, say, the red auxiliary light of RX100M2. However, under certain circumstances a bit disturbing ("Strobe")
- The "old" batteries fit as well as the battery grip and other accessories (remote control etc.) continue
- 1/8000 shutter with specified (high) 150,000 cycles
- It is now not only fits Sony Multi interface as the A77 but also a ISO flash
- Even supposedly "slow" lenses focus surprisingly fast at the A77II

So I hope I have not forgotten anything. I think with this camera each can be happy, which is not necessarily dependent on Low Light Photography. Who's that, then gets probably the A99II panacea :-)
I myself am excited and look forward to the next events in order to test the camera even more practical can (vacation and a wedding).
Actually, I'd love to give 4.5 points since 4 too little and 5 are actually too much. Because, of course, still resonates the big "new toy" -fun and yet there are some items on the negative list, I forgive good 4 stars. It does remain possible to increase for the A77 III ;-)

Update 07/10/2014
#############

Inspired by the question in a forum on the speed of A77II at various memory cards, I tested a couple of cards. This information I have therefore added here as well:

I compared and stopped how long it takes until the red "writing lamp" goes after the buffer is full (ie, the "burst" stops) three cards at 12fps "burst" mode. The whole thing in RAW mode, ie approximately 25 MB per image.

SanDisk Extreme 64GB SDXC: about 17 seconds // 27-28 RAWs in 12fps burst
SanDisk Ultra 32GB SDHC: 45 seconds // 25-26 RAWs in 12fps burst
Transcend 64GB 300x SDXC: about 15 seconds // 27-28 RAWs in 12fps burst
SanDisk 2GB SD: approx 180 seconds // 25 RAWs in 12fps burst

Fast SDXC cards so bring respect. The writing time quite an advantage. Because the buffer is also written apparently during the burst on the card you also creates another 2 more images in series.
Side note: From the data it can be deduced that the camera probably has about 600MB buffer memory.

Furthermore, I have benched the big cards are still on the PC as a comparative value (via USB 3.0). The readings I have purely informative added, since they probably have no influence on this test:

SanDisk Extreme SDXC 64GB: 44MB / sec read, 43MB / sec write
SanDisk Ultra 32GB - 44MB / sec read, 14,5mb / sec write
Transcend 64GB - 85MB / sec read, 62MB / sec write

What stands out: the Transcend is writing much faster than the SanDisk Extreme, but brings to the A77II little advantage. Therefore think the memory of the A77 is around 40-45mb / sec and can therefore no longer of benefit to higher speeds.

Update 12/11/2014
####################

There is now the firmware update v2.00 directly from Sony for download, unfortunately my link was removed here apparently.

Advantages and improvements according to Sony:

- Improved AF speed
- Allows movies with 50p / 25p (PAL mode) and 60p / 30p / 24p (NTSC mode) format XAVC S, supports high bit rates

The update, there were a few days previously on the Chinese side of Sony. XAVC-S works well only when a SDXC card is inserted. However, the image quality due to the higher bit rate should be better visible (analog RX100M2 vs. M3).
The AF is especially in LowLight better and supposedly also 4D AF offer (enhanced motion tracking.

Update 12/15/2014
##################

So firmware installed, went smoothly. The focus is sitting in normal lighting conditions felt faster, XAVC-S works (with SDXC card).
What has Sony not listed was the Einschalttzeit: which is also shortened. Lever around and literally right before the display is on. While then it takes me briefly to the OnScreen display appears depending on display modes but can be a photo shoot you anyway already.
According to the first test, the focus has also become measurable significantly faster, as well as the time between two images!

Kudos to Sony for such a facelift!
