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.

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

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*.

evoprox: What does this remind me of ??? I can only hope for you guys that they don't repeat the NEX desaster (more bodies than lenses) and come out with some decent glass pretty quick before they ditch it altogether yet again. After 3 years in the NEX world my money goes to Fuji these days - couldn't be happier.

Yes yes, because the D800 produces such better output than the A7R. Or even if we go back in time, the D300S so much better than the A500, D7000 so much better than the A580.

No, no and no. Despite big price differences.

goloby: AF sensitivity down to -4eV WOOOW!!! Not even 1Dx or D4s do that!!!!

New boyz is right, about a third of the incoming light in most DSLR's reaches the AF sensors țhrough the semi silvered center of the main mirror and bounced via the small secondary mirror behind it.

iAPX: I found it funny this little body with all this equipment around. Seems I am trolling when laughing about a little mirrorless body needing to be put on a tripod just to take a good picture without motion blurr, especially with one the rare good lens sony offers for it!

Now for video, it's laughable too, with a 12MP resolution (I still use my D300s but who will buy a mirrorless body with 12MP in 2014 to do photography?!?), and none of the advantages you will find on BlackMagic gears.

Still photography? nope
Movie shooting? nope
Lauging? ah yeeessss

" can not go higher than iso 1000"

That tells me you're not using it to its full potential to begin with. It doesn't take a rocket scientist to get good results at ISO 1600 or even 3200 out of the A900.

FlowerHappy: How many negative comments will we see from the 4/3's groupie's

A large part of 4k cameras being used today are filming with external recorders. Why did Canon bother with the C500, you ask?

The question is, why do you bother.

drjs: Says it is using alpha mount. What the heck? A new mount???

The E mount has been an Alpha mount since the introduction of the first NEX (3 and 5, which also carried Alpha tags) many years ago. Only the NEX moniker has been removed.

Alpha E mount native, can use Alpha A mount glass with adapter.

On Apple releases 8GB version of iPhone 5c post (35 comments in total)
In reply to:

Sad Joe: A sign of the times - I'm an Apple fan ( I still have a G3 computer) but since Jobs left so did so much that Apple was….

The difference is that things have moved on since then and operating systems and apps have grown in size and are still growing. Which means less usable storage for larger apps and still no "stand alone" way to expand.

In reply to:

Daedbird: So, if Apple had millions of 5Cs sitting around, wouldn't they just drop the price of the 16gb model? I think the 5C is doing ok, but obviously there is a belief they needed a cheaper model....

The price of unsold stock (if true) is greater.

On Nikon D4s First Impressions Review preview (1042 comments in total)
In reply to:

Photographer Jonathan: I see allot of comments about who needs 400.000 ISO, because no one would ever shoot using ISO that high, but I don't think these people get what ISO really is, but I compare camera ISO to a guitar amplifier, and if you turn a guitar amp up to 10 you can hear the buzzing of the amp, and maybe the buzzing starts at 4 but gets strongest at 10, but with a sensor when you turn it up to 10 witch is the highest ISO, you can see the noise the most, so with a guitar amp, the more powerful the amp is, the less you need to turn it up to get volume out of it, so you get the volume with out hearing the buzz, and with a camera sensor, if it goes up to a higher ISO, it's the same as a more powerful amp, it means that at 12800 ISO it isn't working as hard to amplify the sensor, so at 12800 ISO it's going to have less noise than a sensor that only goes to lets say 24.000 ISO, or 200.000 or so on, so in theory if the sensor went up to a million ISO, maybe 12800 ISO would look like the noise of ISO 500

Except that the analogy doesn't work, because a stop extra ISO range, doesn't make the D4S "work any less hard" at say ISO 12800 than a D4 (with similar performance at ISO 12800 too).

Or 4 stops more range than a D800 doesn't give any meaningfule information for the ISO 12800 in comparison to the D800 either, since you can push a D800 to ISO 400k yourself too. In the end these top ISO ranges are all digital amplified ISO's anyway, just like pushed RAW files.

The new jpeg engine appears to control noise better throughout most of the ISO range, but not without a cost: much heavier smudging of details in the green channel. See for example the green detail at the top right/bottom left.

zodiacfml: Camera makers should be very afraid.

The 5S Pano mode is pretty close to the Note 3 Pano mode. It handles dynamic exposure changes (within the same pano) and stitching a hair better, but the Note 3 offers 27% more vertical resolution and a significantly wider view (360 vs just over 180 degrees max).

clicstudio: Apple had one of the first digital cameras in the market in 1994 with the 0.3MP QuickTake 100...
They should have the initiative again... Hopefully

I meant the first commercially/consumer available digital camera (that actually recorded as a digital image). That was the Fuji DS-X in 1989 (follow up of the 1988 DS -1P which was never actually marketed). 400k 2/3" CCD.

They were at least 5 years late to the commercial market.
