On Opinion: Why the Canon XC10 is a big deal article (810 comments in total)

Panasonic has GH4 and Samsung has NX1 for as good as they are now, both companies or others can learn some thoughts from this model. They can repackage what they have now and produce something better for video targeted applications. The competition is just beginning…

On Sony Alpha a7 II Review preview (799 comments in total)
In reply to:

DenisBBergeron: How Sony Camera sensor can be worst than Nikon or Canon sensors ? Sony make sensors for both !

My guess is somewhere on the sensor there are dedicated cells for PDAF and they are different from the other cells in size, shape and function. So photo image has to map to these cells in the image process -that is called lousy raw compress. Un-pressed Raw will leave unpleasant images in some areas.

Sony Alpha 7 II is on the right direction and other manufactures may follow the suite.
But lens, lens, lens....

Outstanding article and great story. But I hate it requires so many clicks to read through it.

Juck: That slow zoom had better be a hell of a performer for $1000.

@kolyy: you are absolutely correct when you say “F-number is the ratio of the aperture diameter and the (physical) focal length”. It is correct if you only look at the lens. But if you factor-in the sensor-lens as a system, also borrow your word, when it's raining the important things to how much water the roof can absorb are the intensity of the rain and the type of material used for the roof. Since the FX size sensor can collect more light due to its bigger cell size comparing to the smaller sized sensors, it will absorb “more water”. In that sense, it is not fare when you compare a lens mounted on the different sized camera. Someone mentioned 0.5-stops above, may be that is a good start point? I am definitely not an expert on this. I hope someone can put it together for us. Again, your F-number definition is correct.
Cheers, - Josh

On Samsung NX1 First Impressions Review preview (1444 comments in total)

I think NX1 is a very promising camera, but not yet for me to buy it now. What missing in NX1 is 5-axis IBIS and I think Samsung should put it in their body ASAP, because that will make their lenses lower weight and cheaper and make a much better camera system.

If a ring flash is not aroud the lens, it is meaningless to be a ring flash. Am I missing something?

Those kind things you can do once, twice, but you lost credibility very soon..... not a good habit to have.

Sony 7s is a small part of this impressive system. But it is impressive indeed.

On Canon PowerShot G1 X Mark II Review preview (451 comments in total)
In reply to:

Donnie G: Alright, who's the comedian who came up with the term "mirrorless" cameras? Who the heck walks into a Costco, Walmart or Best Buy and says "Hey, can I buy a mirrorless camera? Or, Hey, can I buy a stepless ladder?" Sounds like something important has been left out of the product, doesn't it? I mean I understand what those folks are trying to say: "Mirrors! We don't need no stinking mirrors." I get it. But they need to come up with a new product description or catch phrase to help sell these cameras they claim to love so much. And please no, don't use E.V.I.L. either, unless you want to continue to have warehouses full of "marketless, SLRless" cameras for sale. :)

What is your "mirrorless" comment to do with Canon G1 X?

On Nikon to offer D600 replacements if 'spots' continue article (175 comments in total)
In reply to:

PixelMover: With all due respect to dpreview readers who genuinely had dust/oil/spot issues witht heir D600...
Bear in mind the source. China utterly hates and despises Japan (My wife is Chinese..) and will do ANYTHING and EVRYTHING to discredit/blame/smudge.insult/demean Japan at any opportunity.

The D600 fiasco is just a god-given present to China.

Put it this way. I have spent 4 month is China now and most of the time, they eat Japanese food buy Japanese brands, use Japanese electronics. But every now and then, a government-induced Japan-hate is instilled, where people who ate Sushi yesterday throw bricks throug the sushi bar's windows tomorrow...

@Donnie,
So China asks D600 sales to be stopped because they hate Japanese? Why don't they stop D610 and other Nikon camera sales? Why don't they stop other camera sales because almost all cameras now are Japanese brands? -If your logic is correct.

Put a pure quality issue into such a political spin is laughable.

Why there are two Canon PowerShot G1 X Mark II in the sensor size table? Should one be Mark 1?

Useful to me or not aside, we should encourage these type of out-box-thinking.

On Panasonic Lumix DMC-GM1 Review preview (358 comments in total)

The glass in the lens is not that large but the lens external diameter is pretty big. It makes the body + lens looking unballanced.

On Leica unveils D-Lux 6 Silver Edition article (92 comments in total)

I even don't think you can call it "silver" edition because the body is totally black.

I would suggest Leica just focusing on its lens business…

In reply to:

marcel smit: Totally waste of time and money if you ask me imho.
For that money en size you better spent your money on a decent compact camera.

When you separate it from the phone, it will make a lot impossible photo takings possible now. So I would say it is useful is certain situations.

Just a Photographer: I yet have to see if this will become successful.

My feeling says utter failure - an obsolete product with no future..
That 'special moment' is already over.... once you have finally attached this lens to your phone.

The most interesting thing is not attaching it to a smart phone, but separating it from the phone. I think it is useful in a lot situations.
