On DxO releases Optics Pro 9.1 article (38 comments in total)

Still no Linux version? :-(

BTW (for DPReview staff), the link to the free trial version seems wrong. could you please check it?

MJSfoto1956: while I understand why Nikon wants to protect their turf, this kind of thing actually makes me upset at Nikon, not Sigma. In my opinion, Nikon needs to embrace a more modern concept of photography: specifically, they need to open up their APIs and ENCOURAGE 3rd parties to build for their platform. The best example I can think of is how MSDOS (a totally open system) trounced the early Apple Mac OS -- the lesson being that closed systems are difficult to reach critical mass and if/when they do, then the market starts to offer alternatives (example: the wild and early success of IOS (a closed system) led to the ascendancy of Android (an open system) as developers, tired of all the limits that Apple imposed on them, jumped ship).

Not so open. in fact, very ugly:

On Magic Lantern enables Canon EOS 50D raw video output article (36 comments in total)
In reply to:

Peiasdf: Crack 6D and make it a 1D X? Could happen but Magic Lantern always focus on video. A 7D firmware update type improvement would be great.

Thank god it doesn't have a CF slot. I agree CF cards are faster than SD, but a broken pin is game over until it gets repaired.
Broken pins are so common that in the 5D mkIII they put the CF slot in a different board to make it easier to replace.

ZorSy: "We were impressed by the phone's low light capabilities while shooting some samples at Nokia's launch event in London. We managed to get a recognizable image in a set-piece shot where both an iPhone 4S and a Canon 6D with Tamron 24-70/2.8 VC lens had problems.". Hmmm, how do we take this? 6D with a fast lens is easily outperformed by a phone camera? Comparing phones to phones is fine, this comparison is bold (and rather brave) statement IMO...

Hi Lars,
I don't want to be harsh, but I found your comparison somehow unfair. Maybe if you describe your setup a bit more we can understand better, but I cannot really get why you can handhold a phone for 1/4 sec, and you cannot do the same for the 6D, and change the ISO to 6400 (from 12800).
If you keep the same exposure time on both devices then I think the comparison is fair.

3dreal: f1.8 APSC=the same lightgathering like f2.7 on FF.
so comparing both formats at iso 100 and 1/30 apsc-lens at 2.7 shows darker image than ff-lens at 2.7? i dont get it. discussed here endlessly.
that would mean an external lightmeter must be recalibrated whe switching from FF to aps-c? very strange. fstops- no matter on which formats are all the same in relation to Evs.

Hi,
The whole "equivalence" thing involves the focal length, the f number and the ISO.
So, this lens at 18mm, f1.8 and ISO 100 in a APS-C camera is "equivalent" to a 27mm f2.7 and ISO 225 in a 35mm camera.
Equivalent means that you are gathering the same number of photons in the whole picture, so same framing and DOF.
I hope this helps.

On First Impressions: Metabones Speed Booster article (357 comments in total)
In reply to:

ManuelVilardeMacedo: So you pay a bucketload of money in order to mount (comparatively) huge lenses on small bodies, you lose resolution and AF performance, but get higher levels of chromatic aberration... makes sense.
Wouldn't it be simpler - and less ruinous - to use your Canon FF body when you want to use EF lenses?
Just saying. Some may think otherwise and that's OK with me. It's their money anyway.

You don't need in fact a FF body to compare. Your GH2 has a crop factor of 2, the metabones has 0.71, so your combined crop factor is 1.42.
Since canon APS-C cameras have a crop factor of 1.6, something like the 60D will compare to your GH2 + metabones.
Of course, I'm noly comparing the crop factors, there are lots of differences between those two cameras...

zoranT: Samsung copy everything, first Sony's NEX series, and now they go a bit towards the retro concept of Fuji. And IQ-wise they have been always a bit behind, no surprise. They could bring it on however, if they wanted to be more serious about leading the market.

Zoran, Randy, 2 things. First the NX line was launched before the NEX line, so Samsung didn't copy the name.
Second, google the Samsung NV15 or NV20. They were released around 2007, and they look like the NEX-3.
Please look at the facts.

aardvark7: Perhaps I'm being a little slow, but I fail to see the significance of 'Android based'.

Is there going to be a whole range of companies providing customised user interfaces, or the ability to easily make your own?

Even if this would be so, I'd be more concerned as to whether the physical parts performed as necessary, rather than what software is behind the scenes!

For me it means to be able to run software that can process my pictures better, without having to carry a computer.
so, you can have a different pipeline, you can have intervalometers with custom options, you could probably trigger the camera when a face is detected, etc.
So, your camera won't be a camera only anymore.

Press Correspondent: No kidding, just moon landing pictures alone...

Faking the moon pictures is possible, but I don't think it is possible to fake the landing sites. It is possible to see them with a big enough telescope (like Paranal).

On Adobe releases Lightroom 4.3 and Adobe Camera Raw 7.3 article (69 comments in total)
In reply to:

fierlingd: All this anger towards Lightroom in these posts... lol.

1. Yeah surprised Fuji xpro is not better supported too.

2. Sigma support, well i probably agree with you, but i bet it comes down to priority. They probably had more urgant things to work on for the release. I would ask Sigma why they don't support DNG.

3. As far as "Wasting resources" between the various raw solutions. Variety is a good thing! :).. and besides adobe came out with DNG format! which unifies the cameara formats, so if anything i would blame the camera companies that are not supporting that. I mean common, how many raw formats do they have to support?

4. As far as no Offline update for ACR. I have to ask why does your office have no internet connecion? Personally i think it's obserd (or even childish) to block or prevent net access in an office building. People should be treated as resonsible adults, not children. Net access in the office is an assest anyway.

There is a mode in DNG for cameras with no bayer pattern, so there is no excuse.

Francis Carver: 6D is not intended at all for video shooters, surely. Mono sound (in late 2012!!!), no external microphone input, no headphone jack, USB 2.0, no clean uncompressed video output in active mode via HDMI, and so on.

Nikon D600 at the same exact price has all these features and stereo audio, so it smokes the Canon 6D in a nanosecond.

Hi,
It has stereo microphone jack:

I agree with most of your other complains.

zeidgeist: And the usual bunch of CONSPIRACY CRETINS infesting this site like a CANCER. Even the Russians, who hated the Americans during the Cold War acknowledged that Apollo 11 HAD LANDED. Get with it MORONS...... The same w*nkers who post that, despite the overwhelming proof that it was Al Qaeda and Saudi money, that 9/11 was an inside job, oh yes and the "chemtrails" and HAARP with a touch of NWO and all washed down by th e Bilderbergers. Meanwhile when the US actually showed the landing site via the lunar orbiters, what did the cretin "truthers" spout...... YESSS you guessed it "PHOTOSHOP" and "that proves nothing".......

There is enough evidence that they managed to reach the moon. There are instruments installed (like the array of mirrors used to measure the distance between the earth and the moon), and it is possible to see traces on the landing sites (with the Lunar Reconnaissance Orbiter).
About the 9/11, sorry but I'm not 100% sure.

ALFREDofAVALON: I'm glad they took a Hasselblad.

Bah, my Kiev 60 can do the same! It is just a bit more temperamental, and currently is not overlapping the pictures.
So "almost" the same... ;-)

Birch_Tree: I always thought Android was a resource hungry operating system. Which would mean battery life, Performance or bulk would suffer. Probably better operating systems out there to use in a camera.

My Samsung Galaxy S (single core 1ghz) runs ICS perfectly well. My wife's HTC Legend (single core 600mhz) is a bit slow, but perfectly usable.

Erik Magnuson: Second major flaw in this test. on p159 of the manual Canon warns that the system may have trouble when there is only horizontal detail, I.e. the Hybrid system only sees vertical detail. What did DPR use as a test subject?

The weight of the elements you move is more important in CDAF than in PDAF, because when you do PDAF, you estimate how much you have to move, and then you do it, but in CDAF you move a bit, check, move another bit, check, etc. So you have to deal with the inertia problems of moving and stopping during the whole autofocus process. in PDAF you accelerate and decelerate only once (each) in the whole autofocus process.

perry rhodan: First Yawn second Hilarious.
IQ on par with OMD ? haha. Tried every samsung fom this series for years, because I really like the lenses, they are very nice. Samsung has to try better sensorwise. It's about 4 or even 5 years back in time. Please DPR, it isn't april fools yet. Samples do NOT back-up the conclusions AT ALL. Care to clarify??

Every comparometer shows the samsung line to be worst by far in IQ when leaving lowest ISO. Even small sensor compacts can do this good light low ISO in 2012.

The IQ is bad because the JPEG engine is bad. If you use raw, the story is completely different.
BTW, why are you posting the same thing twice?

Hi!
I understand that DPReview is a US centric site, but do you think you can also put the dimensions and weight in metric values? You know, for the other 95% of the world...

Knight Palm: Previous Samsung models doesn't do compressed raw format. Therefore their raw files are humongous. It's about time to start compressing their raw files, since all other competitors do!

Dear jj74e,
none of the Samsung cameras compress a raw file. for example, the NX10 and 100 have raw files that are about 26-29MB, and of those 14.7*1.5 (12 bit) are the uncompressed raw, plus a 4-7MB JPEG inside.
