straylightrun: No USB 3.0 port? No fully articulated screen? No proper weather sealing? At this price point.... 😬

Of course Ethernet is the interface of choice for tethering.
It gives you so much more than the flimsy USB port
- proper distances
- highest speeds
- solid connector that locks in place, including weather-sealed ones
- proper networking capability, as opposed to only 1-to-1 connectivity
- proper connectivity and data transfer protocols, error correction, control, security features, etc
- Sony cameras run a sub-set of Linux, so Ethernet is in their DNA, it would be a crime of they didn't include one. At the same time USB has so many compatibility issues, especially with Linux.

Someone mentioned WiFi, but it can easily fail, if there are many people in one place, or in large buildings with many wifi devices.

So if reliability is of importance, as it should be with a pro camera, Ethernet is the best choice for thethering.

If you just want to transfer your images to a computer, just plug your SD card into it. All my laptops for the last 14 years!! have had SD card slots.

You can get 40G/s with copper, and it will still be 4-8 times faster and on much longer distances than USB 3.
USB, especially USB 3, is severely limited by distance and speeds deteriorate if the cable is more than a meter or two.
USB has some of the least reliable connectors existing in computer hardware, you can easily lose signal if it moves slightly to the side or can even unplug completely if you're moving with that camera.
That port is there for tethered use, otherwise you can just plug the SD in your laptop.

@Dr_Jon Really?
Do you really think that the USB that's designed to power devices and transfer data is faster than an interface that is solely designed to transfer data?
USB 3 - SuperSpeed is 5 Gbit/s AND you have a limit on the distance
Ethernet - goes up to 100 Gbit/s these days and distances are in the order of 100 meters/yards
Plus you get FTP features with the Ethernet

Who needs a USB port when you have an Ethernet port.

falconeyes: Most underrated fact is on sheet #4:
> memory for buffering immediately behind each pixel

If true, this is a true revolution which cannot be overrated!

It was expected by some but it wasn't clear if the technology is here already.

Sony says it is 20x faster than conventional readout. A conventional readout is approx. 1/10s, so this could be as fast as 1/200s. Unfortunately, it isn't that fast exactly (yet), because the official broschure contains a disclaimer for the electronic shutter: "may produce distortion in some sitiuations, consult support pages" (which don't exist yet). Also, it does still feature a mechanical shutter to be used with flash. Therefore, a good guess could be a figure around 1/100s.

Not a global electronic shutter yet, but coming a lot closer.

But the real revolution is this: a pixel buffer on sensor allows (in theory) for simulated ISO values far below ISO 100 (for exposure times Nx the shutter speed, here like 1/25s for 4x). And correspondingly large DR.

The readout certainly looks fast, as Sony claim minimal rolling shutter effect, looks like they call it "distortion":

Sdaniella: ok ... according to Sony A9 Brochure ...

Continuous Drive Speed (approx. max.)*6

AUTO/Electronic Shutter:*7*8*9
Continuous shooting:
Hi: max. 20 fps,
Mid: max. 10fps,
Lo: max. 5 fps

Mechanical Shutter:
Continuous shooting:
Hi: max. 5 fps,
Mid: max. 5fps,
Lo: max. 2.5 fps

*6 Varies according to shooting conditions or memory card used.

*7 When A-mount lens is used via mount adopter, the speed of continuous shooting varies depending on the attached lens.

*8 When the Focus Mode is set to AF-C (Continuous AF), the speed of continuous shooting varies depending on the attached lens. See Sony support page for compatibility details.

*9 During uncompressed RAW shooting, 12 images are shot per second at maximum

12 fps max ... for the uncompressed RAW purists ... (24mp x 12fps = 288mp/s) ... electronic shutter ...

5 fps max ... for the mechanical shutter purists ... (24mp x 5fps = 120mp/s)

If memory serves me well, it was a once-in-a-lifetime event, but not more than twice in every three consecutive generations, when certain planets align, artefacts may appear in a lossy compressed RAW image. People here made a lot of noise and Sony made a special uncompressed RAW option, which they still ended up not liking in the end.

It was something like
- when shooting a contrasting scene, like neon signs on a night sky
- you underexpose by several stops
- shoot a lossly compressed RAW
- then push it up by 5 ev
and artefacts may appear, but not always.
Only when certain pixels hit a contrasty area. (Compression packs them 7, or maybe it was 14, at a time). Something like that.

Which meant that 99.9% of people were fine in 99.9% of situations, which leaves 0.001 * 0.001 = 0.000001 or 0.0001 % chance for this to happen, which is 1 in 1 million images.

wildbild: Canon and Nikon pro cameras have never been about the camera itself as about reliability and professional service. It takes years to build this and no pro photographer will switch to sony over some 20 fps spec record.

Someone was saying A mount lenses are supposed to work with this body and Sony's own A to E adapter at 10fps.

rjx: 20 fps? geez. Quality vs quantity. Timing is everything imo. 20 fps is ridiculous. Hell, even 10 fps. If you're experienced in what you're shooting, you should have good timing. Even with spray n pray it doesn't mean you'll get the frame that mattered. But with good timing, all you need to do is fire off a shot or two and getting the shot at the exact moment you needed.

@rjx
You'll still be using your perfected timing skills, just instead of a single image, do a burst of 3-4 ones. It would still take only a fraction of a sec @20fps, to be exact 1/5 sec for four images.
Then you'll be able to select the best one, and be pretty sure you don't have something weird happening with any of your subjects in the image. May save you editing time as well.

Mister Joseph: Short of 4fps to be a 24MP camcorder. Maybe next year!

No, it IS a 24Mp 20fps camcorder.
The difference between 24 and 20 fps is not that great. It will even give a bit more "cinematic" look.

In reply to:

PhotoPR: How long is the rolling shutter effect? Meaning how long will it take to capture the reading of all the pixels in a single image?
For most cameras the electronic shutter reading will take about 1/15s even if your shutter speed is set as 1/25000

They claim negligible rolling shutter effect.

It's not only the 20fps, also 93% AF points sensor coverage, Eye-AF, they claim faster response that pro DSLRs, No-Blackout, three AF measurements per frame @ 20fps, silent shooting, can shoot without moving parts, 5 axis in-body stabilisation, and more

On article Sony SLT a99 II Review (1570 comments in total)
In reply to:

BRWAT: I don't agree with this review at all.

I use a D5, D4 and D810 professional daily. I have more time behind the D5 than probably anyone I know. I personally own a A99II and I've been comparing it to my D5 for three months now (massive upgrade from the A850).

The A99II is so close to the D5's performance it's scary. Had it been equipped with XQD and USB C the performance delta would be negligible.

Let's be honest, DPR have always been very subjective with their rewards and % marks. Several years ago, they regularly used to punish Sony cameras for the brand name alone.

For example they completely failed to spot the revolution started by the RX100 series.
The original RX100 was given 78% and Silver, even though it had ZERO competition and created a completely new category itself ?!?
RX100 II was given 79% and Silver again, and they needed
RX100 III to give it 82% and Gold.

In reply to:

rbach44: Playing the devil’s advocate here, but I’m trying to get an answer too: Whats the point of the SLT concept?

Its like mirrorless without the size/adaptability advantage (The two big advantages of mirrorless to me). It seems weird to have a camera with the bulk of an SLR but without an optical viewfinder.

Are there people that prefer EVFs to OVFs? I was never comfortable with them. I went mirrorless twice and ended up going back to SLRs each time. Even good EVFs feel like I’m looking at a computer screen with my scene on it.

Also, is the supposed advantage in AF functionality that great? My D600 has more than useful AF, my old D700 was a beast, and the pro Canikons are unbelievably good in this area. Remembers the 9 point AF that pros would use for sports back in the day? Are these new complex systems THAT necessary?

It seems like a solution looking for a problem to me, but I may be missing something. People seem to really like them. Perhaps I’m officially an old SLR fogey.

I don't think SLT cameras should be compared to mirror-less, they are much closer to DSLRs and have a mirror at the end of the day.
They are actually very close to a DSLR that has only Live View mode and the Finder is electronic so it can work in that mode.
Their idea was to reduce moving parts - fixing the mirror - to allow AF to track at all times, without blackout, increase FPS, reduce parts that can break at the expense of 20% of light. It still has the PDAF module that works off a mirror.
The only thing they had in common with mirror-less was the EVF but this was not considered benefit initially, only a workaround making them possible.
On-sensor PDAF was only added in this A99 II model.

ms18: Great news

Well, the 1.8/8.5 is good news for people that can not afford $1200/$1700 Zeiss & GM 85mm options.
The 2.8/100 STF is good news for people looking for a specialised bokeh, low transmission lens, to use with lights, in studio most likely, who wouldn't have a problem with the price anyway.

Mike99999: Sub-$999 A7 with FE 28/2 - 50/1.8 - 85/1.8.

Should be enough to obliterate crop-mirrorless competitors I would say.

@badi
Check your fats, man, the A7 does have Phase-detect AF.
This was one of the main differences between the original A7 and A7R at release. The higher-res A7R didn't have PD-AF, the A7 has.
It's mentioned literally in the first paragraph:

I wonder if Sony have a FF version of this sensor with 1.6-3.2 million ISO

Especially with A7 III on the horizon ...

@Fujica
"China with its 1.4 billion inhabitants and it does have a large nuclear arsenal that is probably larger then what Russia has"

You don't know what you are talking about.
China has about 300 nuclear warheads, the US about 7000, Russia 7,300.

And during it's peak Russia had above 40,000 warheads, the US above 30,000.
Both countries agreed to bring them down to about 7000 and decommissioned the rest, but never promised to destroy them and are keeping them stored.

So China does not stand a chance against either of these.

@tr573
Obviously I had military power in mind, every normal person associates power with strength and understands military power, when talking about a country. The definition of powerful is "having great power or strength".
Especially, as I had in the brackets right after that "nuclear power" as well.
What did you think I am talking about, nuclear power plants, bakeries, tanning beds maybe?

If I meant economic power, I would have said "world's second economy".
