photo nuts: The G1X does not appear as large as feared. :)

Yes, and compared to the panasonic GX1 with pancake zoom, the Canon has a larger sensor and a lens that is both faster and longer.

In reply to:

morepix: I could almost forgive the slow zoom lens, but settle for a coke bottle OVF: never! Too bad. I had two great years with a G10, and I defected to Panasonic LX5 because at least there's an optional EVF. There's nothihg like being to bring the camera up to your face, steady it, and see all the exposure data you could ever want -- even including a histogram.

So what hypothetical off-duty pro is going to want one of these crippled G1Xs? Not I!

The OVF is useful for its zero latency and battery conservation. I look forward to the day they can pull off a pop-up, zero-latency LED EVF, but this is still 2012.

Aleksandr Reznik: AFAK, all known technologies for "phase detection" require some kind of mirror, usually semitransparent to reflect some light to phase detection sensor, Intresting, where did they put mirror and phase detection autofocus sensor?

Here is a better link. Some pixels are used for phase detection by detecting a limited direction of light. http://www.dpreview.com/news/1008/10080505fujifilmpd.asp

It has AEL-AFL and Exposure Compensation direct buttons - other ILCs miss one or both of these. Some are saying PASM modes are missing ... they are accessible in the menu, so there is no lack of aperture or shutter control. In digital electronics you pay a premium for compact size, so the price is no surprise. Phase detect AF and 60 fps continuous shooting demand a premium price as well.

For those who currently choose DSLR solely for their AF tracking speed and/or image quality needs, this may be the replacement, if they consider compactness to be worth something.

In reply to:

Nikonworks: Android is limitied to 25MB for the processing of a single image. This includes multiple versions generated during processing,
this limits the output resolutuion to being useful for the web but not printing at 4x6.
Android will have to increase this 25MB limit to provide more effective and useful photography apps.
Right now I use Photo Enhance Pro for my journalism work, which overcomes this 25 MB limit effectively. How? Email the developer.

There seems to be a way to get around it (largeHeap?) in Honeycomb:

The real cost of 24 MP for a lot of people might be the post-processing requirements.

For example, to run DXO Film Pack 3 on images larger than 20 MP, they strongly recommend 64-bit Windows with 4 GB RAM or a Mac with 3 GB RAM.

In reply to:

safaridon: DPR

Seems very strange that the NX200 was not even shown on the most frequently viewed list until today at 1.9% some 12 days after its preview by DPR? Most cameras previewed appear at the top of the most viewed list by the second or before the 5th day of introduction almost without exception and based on the current ranking the NX200 must have been close to the top of the list earlier but DPR didn't want you to know? Appears that Canon, Nikon, Sony, and Olympus have more friends in high places at DPR?

My take is DPR for some reason or another chose to leave Samsung's NX200 out of the rankings until now. How unfair and I am not a Samsung fan but rather a m4/3 fan.

My take is that DPR gave the NX200 a boost a few days after the preview by posting an additional news story containing a hands-on video. That's all.

In reply to:

Sosua: Looks the part all things considered, i.e. - handheld, kit lenses, pre production jpegs, high ISO shots are all in very low light at borderline shutter speeds.

There is next to no point in comparing at a pixel level against 12mp cameras.

The NEX-7 should be very capable with some good manual glass, RAW and a good photographer.

Its not a point and shoot.

AFAIK, an adapter for a manual rangefinder lens would not couple the lens's aperture lever to the camera in any way, so you would not be able to use all exposure modes, plus unless you're shooting wide open you will have a hard time even doing manual focus because it would be like focusing with depth-of-field preview on - the lens is stopped down during composition and focusing. Pentax's support of it's own legacy manual glass is far superior because of this.

In reply to:

Philgp: I'm not sure if I'm missing something here ( I probably am), but would't the noisiness be offset if you took photos at a lower resolution setting in-camera, say, 16mp (resolution of Nex-5N)?

Or, alternatively, would the fact that there would be pixel overlapping mean that there would be distortions, if decreasing to anything larger than quarter the pixel count (to c. 6mp, half the pixels in each dimension), which would screw with the image really badly when viewed at 1:1, on the pixel level?

I think if they had averaging of adjacent pixels to create a lower resolution image, they would claim it as a feature, like Fuji does with EXR cameras. Since they didn't mention it, it seems safe to assume that their lower resolution modes are like most cameras: simply throwing away pixels.

In reply to:

Superka: Samples are good. But I don't see all 24Mpx there. All the leaves are blurry mass, for example. I really think that 16 Mpx on APS-C is enough and everything more - just adds blurry pixels. 24Mpx are good for FullFrame.

As long as the lenses are sharp enough for f/8 and wider, the 24 MP should be an advantage in decent lighting conditions. The lenses are a big if, though.

Managarm: Well, ISO 6400 indeed doesn't look good in darkness - but what ISO 6400 ever did?
There is even some noise at ISO 100 visible on dark parts on sample 4 when zoomed in. I know the sensor can do a lot better. Guess the JPG engine/denoising algorithm is not the greatest.

Give us RAWs who needs JPGs anyway?

"ISO 6400 indeed doesn't look good in darkness - but what ISO 6400 ever did?"

D700 ... for only $1000 more of course :)

In reply to:

SW Anderson: For $899 an optical viewfinder as standard equipment shouldn't be too much to expect. The new sensor has 21.6 million total pixels,
20.3 million effective pixels. That must be for users who standardize on 4x6 prints — 4x6 feet.
I don't like to sound so negative, but running up the price with more megapixels than make sense for 98 percent of photographers, likely at the expense of image quality, is a poor idea. So is omitting an zooming optical viewfinder, IMO.

The thing is, it's a large sensor. If the pixels on this sensor were packed as close as the Panasonic DMC-G3, it would be 25 megapixels. So out of Samsung, Sony, and Panasonic, Samsung chose the lowest density for their sensor. And the price difference between NX200 and G3 is easily justified by other attributes. So the idea that they're "running up the price with more megapixels" is a misinterpretation, in my opinion.

Deleted-pending: Good times ! ALL what we have been expected for only 2 years ago from now comes into place : lots of brands are coming out with GREAT portable APS sensored cameras ! This Samsung pocket-able looks great, it just needs a smart marketing, some good prime lenses & a twin video camera, to match sony & panasonic.

I find the NX100+30mmf2 about the same as the G11 as far as the ability to fit in my pocket. The NX100 is slightly deeper when you include the lens, but it is not is tall. They are about the same weight, including lens and battery. The 30mm F2 takes a 43mm filter directly, while the G11 needs a bulky adapter to allow filters. The NX200 is even smaller than the NX100.

eddiegforce: Very interesting article on Luminous Landscape regarding

Compact System Camera Image Quality

authored by Kevin Gross, Norman Koren, Randy Bockratth and Jason Cope of Imatest LLC

http://www.luminous-landscape.com/essays/csm_image_quality.shtml

Interesting, but very flawed and misleading - the article frequently makes statements comparing "CSCs to DSLRs" which in actual fact only relate to the sensor size. In fact most of the comments that are not related to sensor size are not directly related to image quality.

Chris Tofalos: Great spec but the lack of an EVF greatly limits the camera. The NEX-7, with built-in, super hi-res EVF, looks a much better bet.

Frankly, IMHO,the NX200 is a white elephant!

never mind, the preview says the new contacts are for power

Don't be so sure ... there are now two more contacts on the hot shoe than there were on the NX100 - we don't know what they are for.

"New touch-screen interface for quicker, easier use" seen on the Samsung US site - is it not true?

In the Comparison with NX100 chart near the start of this article, the heading images are both NX100.

Metal body? Yay! Cool!

Nice to see it pictured with the nascent lenses.
