Prognathous: Questions from a current A77 owner:
- Is it possible to select JPEG-only features (such as Panorama or HDR) when the camera is set to RAW+JPEG? If not, how easy is it to temporarily switch to JPEG-only? In the old A77 it can take up to 8 rear dial clicks + more fiddling using other controls and is extremely annoying- Is there a way to limit AF to use and display only cross-type points?- Is CDAF available?- What's the fastest framerate with live view (that is, without slideshow effect)? In the old A77 it's only 3 fps.- Is the EVF less prone to washout when daylight is reflected off the photographer forehead?- Does the camera use signal amplification beyond ISO 1000? The A77 only does a digital push.- Is the video still cropped if stabilization is turned off?- When using magnified mode of a specific part (in liveview, not postview) does switching to MF (e.g. to correct imperfect focus) switch the camera out of magnified mode?
more in the next post...
Almost all cameras using Sony Exmor sensors digitally amplify beyond ISO 1000-1600 (including Nikon and Pentax cameras). That isn't necessarily a bad thing, or for that matter something that will impact usage in any way.
Thorgrem: Looks like a nice camera and a real upgrade for older and lower Sony SLT/dSLR models. But no new lenses are announced?
The FE lenses work fine on APS-C too. A 70-200 F4 lens made just for APS-C would have been similarl in size and weight. In fact, I see A6000 users happily use them already.
A small error in the specs list.You list: ISO 100 - 16,000 (25,600 with multi-image combination)Sony lists: ISO 100 - 25,600 (51,200 with multi-image combination), ISO 50 as an expanded setting.http://www.sony.net/Products/di/en-gb/products/g2sw/specifications.html?contentsTop=1
btwango: Isn't "fixed-mirror DSLR" an oxymoron?
Why? The reflex part implies reflection, not movement.
RichRMA: These things are probably so tightly integrated, they just crush the ones that come back. There goes Samsung's profit margin.
The camera module is indeed relatively easy to replace.
DFPanno: If Sony intends for this camera is to be considered a true successor to the RX100 it must continue to fit in a man's trouser pocket.
(And by trousers I mean slacks; not wide-boy cargos and the like)
Any improvement that precludes that context pushes it into an entirely different class of camera completely IMO.
Once I need a bag (I don't do the camera on my belt thing thank you very much) there is a lot of competition out there.
Having any phone and a camera in the same pants pocket sounds like a bad idea to me. That being said, the RX100 II fits my regular fit 32/32 jeans pockets fine.
falconeyes: This will become the camera with best image quality ever made up to today!
(in terms of DxOMark, it should score around 105 Overall Score and 50MP, even though the jump from 35mm is small (0.79 crop)).
I hope that Ricoh releases the marketing money needed to make this a bold statement for Pentax being overall leader in IQ. The brand needs a bit of hype to make a come back, esp. in the US.
"so chances are high Pentax deploys their famous magic to lead the score by a point or two again. Ask Nikon and Sony"
Possible, altough if their last example (K-3) is any prediction, the opposite could be true too.
sam james: I am a professional video person and what I am noticing is at ISO 3200 the compression artefacts seem quite visible, comparable to the older 5D Mk2. The 5D Mk3 was about 1 stop faster so this kind of noise would only be visible at about ISO6400. Then what we see in this video is that once the brightness is lifted at around 25,000 ISO the noise issues are less obvious because noise is always more visible on darker areas. I definitely agree that this seems to be shot to underexpose at ISO1600 to amplify the difference at 400,000 ISO. My guess would be that we could actually see quite a lot at the Sony's 1600ISO with not too much noise and the ISO above about 12800 would not really be necessary.Anyway, it looks good, not dissing this camera! Though my Canon c100 has less noise than this at all of the ISO levels up to 52,000 though so I'm not totally amazed!
I'm shocked you see compression artifacts in shadows from a youtube video.
Wake up call: Youtube compresses too, especially in shadows.
mastrolittorio: a question to those who are more experienced than me. I never do video. but that function that increases DR in the video, also works for the photo?
No, it will likely (see the A7 and A7R and other Sony cameras) have DRO for jpegs which does something similar, HDR multi frame exposures and of course RAW to apply a similar compression (curve) of the DR yourself in your converter of choice.
aruk5: Wanted to add one more thing. I hate Sony's strategy of releasing a new camera system with many useful features deliberately missing and then within a few months or a year they release a 'superior' version of the camera system with the very useful features which should have been added in the original release. Remember when they came out with the Nex-3 and Nex-5 which didnt have full manual control in video but soon they released the 5n, nex-6, nex-7 with full manual control. Those who bought the oriignal nex-3/5 were left with an inferior product and hardly any resale value. The same could be said about the slt series. Also in slt series they didnt provide any sensor based contrast or phase detect af and if u removed the slt mirror [to improve image quality] you couldnt use the af! Reg a7 series! the 1st ones didnt give uncompressed video output and then they come out with the a7s which can shoot 4k video and give 4:2:2 uncompressed outputs! feel sorry for those who bot the original a7
No, too much processing involved to downsample and in general they said overheating was too much of an issue with those sensors.
Horses for courses, that's why they give you a choice between the 3 of them.
Both the A7 and A7R offer uncompressed hdmi video out.
EOSHD: You can't judge noise levels on YouTube. Compression removes it. ISO 1600 looks worse than 25,600. There's also the matter of rolling shutter on this camera, it isn't pretty! http://www.eoshd.com/content/12631/sony-a7s-rolling-shutter-test
No, larger sensors have always been more prone to overheating, all else being equal. More resolution is a strong contributor too. But Sony already has very small sensors with a global shutter, 4K and 120 fps output, the first for quite a few years, the latter 2 for well over 6 months. Rolling shutter has been battled much more effectively with their small sensors too. Even in very compact smartphones with lots of surrounding heat sources, cooling is much less of an issue for those small sensors.
I did mention practise rather than theory and yes, that obviously has to do with economies of scale too. But there are similarities with computer chips where shrinking allows efficiency and thermal improvements as well.
Mike Griffin: Why does the fire appear not to get proportionally brighter in step with the rest of the scene?
Grading after Slog-2, compressing the highlights.
KrisAK: Whatever happened to those Canonian fireflies?
House of Cards is available in 4K. And since we're talking Bayer sensors, there are plenty of benefits for resolutions lower than 4K too, including 1080P.
aftab: What is Slog-2?
Version 2 of a custom gamma curve that has gotten famous in the film business for compressing a very large DR into a single file, which results in a very flat looking output with lots of latitude that is perfect for grading afterwards. Good for opening up shadows and preventing highlights from burning out in video.
Actually in practise, surface area is a big factor (alongside resolution) because the larger the sensor, the longer circuit lines, the more heat becomes a factor and the harder it is to get fast read out speeds (ceris paribus), which is one of the critical factors for rolling shutter (besides how it's read out etc). That's why an RX10 currently performs better in this area than its larger Exmor brother. That's why global shutters are often introduced on smaller sensors first, while APS-C and FF sensors in still cameras will have to wait a little longer.
Dominick101: DXO lost all their credibility which is for sure. Look into the fine details of their scores between 808 and Z2 and you will see how mismatch their comparison is. If you look further into the scores of iphone5s and 1020, you will, too, be shocked. DXO being a reputable site puts out bias rubbish scores which are most of the time subjective to the tester/user.
The 808 is great in many areas, but DR is its weakest point. To mask/avoid relatively high read noise (affecting shadow), it meters extremely high, with lots of clipped highlights (and even some midtones) as a result in almost every shot.
ryansholl: I have no intentions of every buying a 4k TV, if I'm given the choice, anyway. I feel like we've definitely reached the point of overkill.
I am excited to see what this puts out at 1080p. A compact low light machine that can finally lay down some incredible 1080p video would be more than welcome.
"I have seen one. There is a difference from 2-3 feet."
Then again, some people (myself included) must have much better eyes than you. I clearly saw a difference over 9 feet still in a side by side comparison.
(unknown member): Hi Jeff . . . this is Dark Cobra from your old site. I was glad to see you return to Stanford and San Francisco for many of these shots and we are very used to many of these scenes from your old site. In general the images are at best "alright". I don't see anything that WoW's me at all to be honest. The bridge night scene is good as is the Stanford "tunnel of doom" shot which renders excellent shadow and light detail balance. The sharpness of most of these images could be better. I was thinking about getting this camera but I'm SO glad I resisted and picked up the incredible Fuji X100S. Take care of yourself Jeff!
Agreed, love the return of the well known SF scenes, good for comparison purposes!
And it revealed a lot of edge halos from excessive edge sharpening with a large radius, yet mushy low contrast detail, already at base ISO.
Just a Photographer: Why buy this camera if it doesn't work out of the box as advertised?
4K video is only there when you buy additional hardware.12 MP on itself is not of these days anymore, although it will deliver good images at high ISO's (if Sony Digital Imaging doesn't screw up, like they often seem to do - Great sensors, but bad camera development).
Typical strawman in an attempt to cover up the obvious nonsense.
It's amusing to see the hard work done by the usual suspects again, to detract from a camera none of them has even used.
It's ok, you made the right choice. *pat on the back*.
