Thank you, I did it b&w to honor my old times ( early 70's ) when I shoot with a Leica M2 and two primes: Summicron 50/2 and 90/2. Of course that's San Francisco...!

King of Song: This changes everything, at least for me. I knew this was going to happen. I was searching for a reason to buy the new Canon 5DSr, just because I'm already invested in the Canon system. But I already knew the Canon is obsolete, even before it is released. The mirrorless is just a better concept altogether. Sony has just done the seemingly impossible. That's break into to exclusive pro market, forever dominated by Nikon and Canon.

Does anybody want to buy a Canon 6D, with 35mm 1.4 Sigma Art, 50mm 2.5 macro, and 100 2.0 Canon lenses, all mint, for cheap? haha

PS> If Sony was really smart, they wouldn't sell this new sensor to Nikon...

On top of it all, it will fastly AF with Canon DSLR lenses plus a Metabones electronic adapter!

In reply to:

Lucas_: I've been shooting for three months with the A7 and close to two months with the A7II, now. The A7II adds almost everything that I wished the A7 had: better sized grip, more robust body, more assignable buttons, faster and, among other features, more accurate AF ( although I mostly use MF ) and the fabulous on-sensor stabilization. The "noise" DPR mentions is only on jpg and actually same ( even less in proper conditions ) as the A7 ( which didn't cause any disturbance on DPR at the time... ). I find it that DPR was in the least careless in having two apparently less experienced new comers reviewing the A7II, a most important camera for the current photography scenario, being another great benchmark launch from Sony. A real shame.

- Dan, I didn't say you were careless, I said DPR was for assigning such a tough job to a newcomer ( no ofense ). Anyway, I don't find the A7II to be bulky at all, it's actually robust! I bought it, already having an A7, because It has important improvements over the A7, without losing anything - the small increase in weight and thickness are way offset by the excellent grip and IBIS. I won't even comment about noise...!
- CaPi, IMHO DPR is the one imposing their opinion on us readers! I've been in photography for over 40 years, obviously having had a multitude of different photo equipment brands ( Leica, Zeiss, Nikon, Minolta, Canon, Olympus, Sony... ) but mostly Sony on the last 8 years. I don't know what you mean by "Fanboy", but I'm really happy with what I have now, since it fulfills all my wants and needs!

The A7Ii is such a wonderful and groundbreaking camera, that DPR had to dig out something like "high ISO noise" to not give it another gold to Sony...! Since I bought it my excellent A99 startedto see a lot of som shelf time. I believe DPR is also mistaken when saying that the sensor is the same as in the A7. This review seems to have been done in a hurry and under a lot of pressure from canikon, etc... Nevertheless, most everybody knows now that Sony sensors are by far the best out there. I feel positive now that the "new" 50MP Canons will get the gold...!

In reply to:

Pitchertaker: Trying to choose my first digital SLR to upgrade from my Canon Powershot 40 2MP point-and-shoot, which I love but have advanced enough to want something more powerful and full featured.

I'd like some advice if possible in choosing a make/model based on the types of photography I enjoy, and what you think would serve me best for such subject matter: nature, landscape/cityscape, portraits, street/candid, macro, winter, B&W, flora/fauna, architecture/perspective.

Been looking at the Sony A7, A7s, A7r, and the Alpha a-6000; Olympus OM-D E-M1 and Nikon D7100.

Grab an A6000 with the 16-50 and 18-135 f4 lenses and you'll be in heaven for some time and won't miss your p&s. After that, there'll be no limits for you!

In reply to:

kai liu: I did not see you mention this. and it is important. 1080p full frame mode is pretty useless at 50/60p. It produce too much moire and aliasing. However at aps-c mode at 50p/60p. This is much reduced and perfect usable. So if one need 50p/60p slow motion, he better give up full frame mode and stick with aps-c mode.

Not with the A7S! The full sensor readout and low pixel density are some of the great features that prevent those problems. The A7S is a landmark, having "raised the bar" quite higher than ever for video with this type of camera.

spatz: The real game changer would be a number of Sigma lenses released for E and EF. Until then, these fantastic cameras are still paper tigers.

Unfortunately the new Sigma "Art" lenses, although excellent performers, have been very bulky and heavy. Not really Sony Ax style.

Stephen787: It is amazing how sony put an ibis in such a small camera.
After living with electronic shutter from sony A7s, i will never again buy any camera without that feature.
Therefore A7II is not for me. The next version with electronic shutter, i will buy that one.
Is sony the same company that going bust? How do they do that!

Have faith. An A9 may be around within a year...!

In reply to:

chj: To Sony (and all camera manufacturers)

Put a damn touchscreen on your cameras. It is by far the best way to choose a focus point. Anyone that says otherwise has simply not used one and is exalting their "skill" in getting around their camera's limitations. Technology trumps skill. You can't get faster, more reliable autofocus than my GM1 (unless you have another Panasonic). Don't tell me about workarounds. The GM1 nails focus more often.

OK, manual focus can get tighter focus on a stationary subject that's willing to wait for you to set up. But with that kind of time, ANY camera can get tight focus.

So stop listening to photo geeks that equate touchscreens with bad phone photos. On a GOOD camera, a touchscreen is an immensely powerful tool that has more impact on photos than pixel peeping details.

Feedback from DPR photo geeks is 0.005% of the market. The other 99.095% are using touchscreen phones. The camera market is shrinking, because you are listening to the wrong market.

I mostly compose and focus through the EVF on my Sony cameras. Moving the focus point with Sony's joystick control is a breeze ). The LCD is only used for checking menus and changing parameters when not in a hurry. Touching the screen usually helps to make the screen greasy/dirty on my tablet and phone!

In reply to:

FrankS009: About a hundred grams (roughly 20%) heavier than the old model. The same weight as a Panasonic GH4, and more than an Olympus EM1. That frankly is heavier than I would like to lug around, not counting lenses.

F.

No comparison, the A7/A7II are Full Frame cameras!

Direct link | Posted on Nov 20, 2014 at 14:31 UTC

This is great news, kuddos to Sony (again)!
Now we A7 late adopters ( I just bought an A7 two weeks ago... ) will have to beg Sony to release a FW for the A7 at least with the A7II enhancements which are only software related! AFAIK both the sensor and Bionz processor are the same, so the 30% AF speed increase may well be one.

davephdv: I have a GX7

I use a Sony RX100 to supplement it, but am not totally satisfied with the Sony.

Should I buy a LX100?

Try an RX100III or an A6000!!

Lucas_: Quite interesting article. Anyway, I'd ask: why buy a GX7 if you could buy a Sony A6000...?

I can't find anywhere the statement from Sony saying they won't make any more APS-C lenses for E mount.
Please help.

Sony even made the new "E" mount for APS-C ( starting with the NEX camera line and now also shared for FF and FE lenses by the A7/7r/7s series ). The new Sony G and Zeiss lenses for that mount show excellent optics and are small and light.

Foroa: Well, I am using the 18-105 G f4 lens (27-157 eq) on my Sony A6000, and I feel that, at 430 gram, it is a nice compromise.

Agree! I have an 18-105 f$ for my A6000 and it's a real gem: light, fast to focus, great colors. Some say it has high distortions, but the camera easily compensates for it for jpgs. RAWs are also fixed in pp.
