star shooter: This sensor would be ideal for the Astronomical fraternity and hopefully inspire Canon, Nikon or even Sony, to bring out an Astro DSLR that has full corrected colour and sensitivity to equal or better the now defunct Canon 60Da.

"if you know what you're doing"

If you're dreaming about analogue signals rather than useful data.

" or clean 1080p Low-Light video capture
what others have YET to do with stills or video"

If you close your eyes and ignore the A7S, which no current Canon on the market can equal in low light for both S/N ratio in video or stills.

semorg: 1/3 inch sensor at 1.27 megapixels = 63.5 megapixel Full Frame sensor!

"every mfr is guilty of this."

That's why Toshiba, Sony and Nikon are not able to get a useful 14 stops (or more) of DR out of their sensors either after passing through the ADC's and the rest of the chain. Oh wait.

Even some APS-C cameras manage to output around 14 useful stop of DR.

Contrary to the DR numbers you quoted, which no one can ever extract from those cameras, due to their noisefloors, never mind banding further diminishing useful output.

peterwr: "The ability to render color in near darkness is useful in automotive cameras that must make do with light on moonless nights."

Since most cars (and drivers) use headlights to deal with moonless nights, I'm guessing we're talking about *military* automotive cameras here. That and/or autonomous vehicles. Interesting, nevertheless.

Headlights mostly point forward. Sooner or later, cameras such as these will become additions to or replace mirrors (in some cars they already are/do). And automatic obstacle detection (or even braking) systems can benefit from cameras covering a much larger angle than what the headlights cover too. "Eyes" all around the car.

TrojMacReady: Maybe worth mentioning here that Lollipop finally supports RAW shooting. Not sure if the Nexus 9 (and 6) camera apps natively support it, but 3rd party apps should soon allow it.

No, my comment was more towards Android 5.0 (Lollipop) devices in general.

..and the first 3rd party app with RAW support for Lollipop (in this case for the Nexus 5) is a fact:

Some hefty vertical banding in sunset shot #14, especially considering this was already downsampled a lot.

Richard Shih: Nexus 6 phone dimensions:

• 159.3 x 83 x 10.1 mm (6.27 x 3.27 x 0.40 in)

Kindle Fire HD 6 tablet dimensions:

• 169 x 103 x 10.7 mm (6.7 x 4.1 x 0.4 in)

~10 x ~20 x 0.6 mm difference. At least this is the first thought I had...

But 78% more green subpixels, to which the eye is most sensitive (see Bayer for example).

kevin_r: I'm just getting this definite impression that Amazon/Dpreview is at loggerheads with Sony.
They seem to be sending a message that Sony will be treated with scorn and contempt unless Sony ponies up some moolla somewhere.
Why do I say this?
Look at the treatment the Sony A77 mark II is getting even though it has been out on the market since August already.
Then, this specific article is clearly sending the message -
"Oh, sorry, we didn't see you there - your cubicle was so small and unnoticeable....!"

Great way to go, guys. Keep it up. Sony will soon cave in and spend some moolla as required.

Never enjoyed the CD and DVD, did you (which Sony and Philips introduced together too).

Marcelobtp: Sony should pusuit with A7 cameras the low megapixel low light performance and video performance in a box.
And sports Af if possible.
High megapixel count needs to be put in a very good tripod, and very good lenses to get the best of it. A7s is not a niche if priced right. I would switched to sony if A7s had better and faster Af, and the 4k video internal.
Next iteration please bring this, and make more faster primes.
The core of the system should be faster and small primes with aperture control.

Anything larger than f/1.8 loses increasing amounts of efficiency on digital sensors due to the combination with oblique light rays.
Cameras mostly compensate for that under the hood through extra gain, so you don't see that in your shutterspeeds, but you can notice it in the amount of noise. In practise this means f/1.2 lenses practically give you no extra usable light over f/1.4 lenses. In other words, there's little benefit, other than a shallower DOF. But on FF, you can get plenty of shallow DOF at f/1.8 to f/2 with mid to longer FL's and at real wide FL's, even f1.2 won't give you much to boast about in terms of limited DOF.

"F2.0 is still pretty slow for primes, yes."
Hollow general statement. Show me your >135mm lens faster than that. And yes, factoring in equivalent apertures (accounting for DOF and total light), those Fuji primes suddenly turned "slow" or "consumer oriented".

"They are not bringing you fast primes "

Because a 55mm f/1.8, 28mm f/2, 35mm f/1.4 and soon to be disclosed "large aperture prime" according to the roadmap (likely 24mm or 85mm) are slow?

@ vscd :
.."Memorysticks.. "
Funny people still mention this. Since we're on the subject of cameras, every ILC Sony has released since it took over Minolta's imaging business in 2005, has supported both Memorystick and SD card formats. The benefit of choice, rather than forcing it on to us. In some cheaper cameras that actually resulted in the luxury of having dual slots.

Another example: Sony currently has only 2 battery sizes in its ILC's and the larger one sold and used now, can still be used in cameras dating back almost 10 years. Neither Canon, nor Nikon has that kind of battery policy.

"here's just no reasoning with you people."

Not if you think there's only been two upgrades from the A77 to A77II.

- New imaging sensor (up to 0.5 EV cleaner in midtones, to 1 EV in shadows)
- New AF sensor with > 4x more AF points, more than double the coverage and increased sensitivity
- 3 times faster Bionz X Imaging processor
- Deeper buffer (2x deeper in RAW, 4x deeper in jpeg)
- Wifi added (also for wireless control)
- NFC added
- New EVF with up to 3 times more DR and resolving power
- New calibration options for EVF
- Stabilized EVF view
- New AF tracking options and algorithms
- Updated/added (double layered) weather sealing
- Addition of Quick Navi Pro
- Larger flash compensation range
- New "standard" hot shoe plus extra connector (for mic, XLR module etc)
- Audio monitoring and more control
- Zebra stripes for exposure monitoring
- New LCD (white dots for better brightness)
- Uncompressed HDMI out for video
- Extra custom memory presets and much more customization options

In reply to:

rabbitzilla: They are shouting like they have "released" the lenses. But many in Photokina were mock-ups.

Sony use a very different way of marketing. When Nikon & Canon announce something, they are ready to sell it and most of the products have been in field-testing for weeks.

It may be and industrial standard of new product introduction in future. - -"

BTW, obviously, A7 body is becoming too small for FF high performance lenses. I believe Sony will enlarge the body eventually.

The 1DX, 1DC and basically many of the (super) tele lenses disagree with you.

55mm f/1.8 sounds close enough. Zeiss also releases a native 35mm f/2 and 50mm f/2.

"it barely qualified as a refresh"
It's easily as much of a refresh as the 7Dmkii.

ManuelVilardeMacedo: I liked this interview. Mr. Ishizuka is thoroughly honest, realistic and straightforward. He acknowledges that photographers tend to build systems around their lens collection, so he reckons Sony need to offer more lenses if they expect to counter Canikon duopoly. That's a breath of fresh air; given the way consumers are specs-led, it would be easy for Sony to concentrate on offering cameras with over-the-top specs, but they don't. Sony seem serious about the photography business. Some decades ago it was different, with pseudo-innovations that were obsolete in a few weeks' time and loads of useless gadgetry. Now Sony are more down-to-earth. That's very welcome.

Or to complain about detractors in other (Nikon, Canon) forums, only to try real hard to do the same in a thread about Sony.

FUD squared.

They didn't abandon the NEX system, they renamed it.
They didn't introduce a new mount, they added full frame sensors (and lenses) to an existing mount.
Still the A and E mount.
And a lens roadmap for the latter.

Marty4650: Sony is pretty much the "Anti-Canikon" because they innovate constantly while the big two sit on their laurels and take very few risks. There is nothing bold or innovative about tweaking out another digital Rebel model every ten months, or making minor improvements to last year's Nikon DSLRs.

Because of this, Sony is all over the map, supporting various systems and lens mounts. It can be pretty expensive for them, and it can make it harder for them to be profitable. But they are the only company that has the potential to replace one (or even both) of the big two in the future.

@ Menneisyys:
I paid about €130-€160 for both my 50 and 35mm f/1.8 lenses (each), new. Does that qualify as "super cheap"?

On Canon EOS 7D Mark II First Impressions Review preview (1866 comments in total)
In reply to:

Karl Gnter Wnsch: Kudos to Canon, just like the 7D with it's ground breaking AF system (5 years ago it was and it still performs better than most of what came afterwards) they again put in a class leading AF system into their flagship APS-C - yet this time class leading means ALL DSLR... They didn't leave one stone unturned in it, f/8 focusing, -3EV focusing, 65 all cross type AF points, tracking assist with metering sensor (like their main sports pro camera 1Dx), extreme large frame coverage, spot AF, incredible grouping abilities...
Pair that with a evolution of one of the best APS-C sensors (the 70D) and the buffer sized to match the available frame speed and you have the complete package that will be hard to beat by any of it's competition...

If you had actually read before your usual ranting from frustration, then you would have already realized that this was based on theory, taking noise from other stages out of the equation. Not because of practical use, but to prove that the sillicon before A/D conversion is not more efficiënt either.

And extra DR at low ISO is not a burden, for as long as the DR in most contrasty scenes still exceeds what the sensors can capture. Your Canon camera jpegs already have a larger DR compressed to a smaller DR for displaying purposes. Starting with an even larger DR isn't a downside, it adds choice. Especially now that OLED displays (>12 EV display possible) are within reach.

Your F1 reference is another clueless one. The Tyrrells were shortly competitive, but their special (small) front tyres were starting to lag in development compared to the regular ones. The ones with extra wheels at the rear never saw real action due to quick regulation changes regarding driven wheels.
