Calvin Chann: I hope it solves the issue with defocusing before refocusing. Makes the 40-150 pretty unusable for sports.

And still no HDR mode?

HDR done right gives a better approximation of how the scene appears to the eyes, than an unprocessed photo does.

OzarkAggie: There been some angst in the Powershot forum because the G7X & G3X are using the older sensor but from I can see there's really no significant improvement for stills. Sony does have a bit more resolution yet in real world use I suspect the longer lens will prove to be the greater asset.

To be fair, Canon does offer an optional EVF, so calling the long lens a useless gimmick is unfair. The problem is that Canon expects people to buy an expensive accessory, when the competitors include it in the camera (but not for free, of course).

aftab: RX100 III and IV are noisier than LX100. Quite evident at ISO1600 and higher.

Saying that you can't compare the output from different sized sensors implies that people shop for cameras with a specific sensor size in mind. In fact, those cameras compete for the same customers, which means that they are very much comparable.

Dave C 150: I still don't understand what the advantage of a mirrorless camera is supposed to be. If you need a big telephoto and I do, then it eliminates any size difference straight away. So what are the advantages ?

The main advantage is more an advantage for the manufacturer, not the consumer. Mirrorless cameras are cheaper to make than DSLRs (comparing bodies with similar build quality, sensor size and so on), because they get rid of complex mechanical parts that need precise alignment.

And in a shrinking camera market, where the manufacturers will need larger profit margins to compensate for lower sales, it's almost inevitable that mirrorless cameras will (mostly) replace DSLRs.

Petrogel: If the price will be similar to the IQ, then i'm sure it'll sell like hot cakes......

Petrogel:

I'm not sure it's wise to continue this thread after a week of peace, but here we go.

As you acknowledged, I understand that a CFA adds information to a monochrome sensor. Likewise, removing a CFA from a colour sensor would cut off information from that sensor.

However (and this was the point I was trying to make before), never adding a CFA in the first place does not mean that information is cut off, because the colour information was never there to begin with. You can't remove something that isn't there!

Basically, our disagreement is semantical, since we obviously agree about the technical facts.

In reply to:

stromaroma: Posters are missing the point. Sure this camera has lots of technical glitches just like the first iPhone did, but it's finally paving the way for attached cameras to your phone. Give it a couple iterations and maybe see some other manufacturers jump on board with the idea. Finally the camera business is moving into the future, not lagging behind it by 10 years.

Yes, JK Imaging sells two Kodak-branded models, and Sony also has the QX30, so this DXO camera is the 8th of its kind, unless there are even more out there.

On Canon EOS Rebel T6s Review preview (432 comments in total)
In reply to:

BigOne: "Canon's EOS Rebel T6s (760D) is easily the most advanced model yet to enter the company's beginner-friendly DSLR lineup."

Just don't ever forget the well hidden "company's" part.

The beginner's camera market is fully dominated by mirrorless models of which Canon has none. This monstrosity lacks in every single aspect you can think of. It's heavier, slower, less advanced, has worse AF than ANY competitor in this category. Even Nikon's D5500 drives donuts around it.

I just realized I could say it much shorter.

AVOID!

Well, sales-wise the beginners' market is actually dominated by Canon's Rebels and Nikon's D3xxx/D5xxx models, still the bestsellers in the system camera market. The Sony A6000, probably the most successful current mirrorless camera, doesn't sell in those kind of volumes.

Mirrorless sales aren't skyrocketing at all, they have been more or less constant for a couple of years now.

Wasn't Aptina recently bought by another company, that focuses on sensors for other applications than consumer cameras? If so, I believe Nikon may be using a Sony sensor now.

Even though a CFA is part of every colour sensor (except Foveon), it's wrong to say that Leica cut off information from the Monochrome sensor. Why? Because they never had a colour sensor to begin with. They didn't remove the CFA, they simply never added it.

A CFA adds colour information to a device that natively can't see in colour. Not adding one doesn't remove any information from that monochrome sensor. However, adding a CFA would add colour information, but at the cost of taking away some luminance information, and introducing false information through interpolation.

Basically, what I and others are objecting against, is the failure to distinguish between removing something and never adding it in the first place.

In reply to:

justmeMN: Reality check: According to Sony's May 27, 2015 financial documents, Sony's worldwide ILC market share is a weak (by value) 11%. The introduction of a new $3,200 camera body won't significantly change that.

Smartphones, not Sony, are the biggest threat to Canon and Nikon cameras.

I don't really have anything against Sony cameras, but the breathless hyperbole surrounding them is just silly.

Mirrorless cameras don't have 99% of the camera market, not even close, unless you include smartphones. But if we consider dedicated cameras only, CIPA data clearly shows that DSLRs have a much larger share than 1%, both in terms of unit volume and value.

On Sony RX100 IV compact shoots 4k, uses a stacked sensor article (303 comments in total)
In reply to:

HowaboutRAW: What does "stacked sensor" mean here?

The stacked Exmor RS design was introduced a couple of years ago, and has been used in phone cameras and in the KW1 'perfume bottle' selfie camera.
Foveon's sensors are completely different, and are usually called 'layered' rather than 'stacked'.

In reply to:

Pandimonium: Strange, NX-500 sensor looks sharper than the nx-1, but high iso is worse.

The difference in the raw conversions likely only reflect a difference in the default settings applied by ACR.

If I'm not mistaken, the PDAF implementation used in previous Nikon 1 models was a Nikon patent, not an Aptina one. So even if it's a Sony sensor, the PDAF might not be exactly the same as in the sensors Sony makes for their own cameras.

In reply to:

Paul Verhoeven: His explanation of the way to use the EF mount 400mm Sigma on a newer Canon EF mount camera is terrifying.
Why not to use just an appropriate modern lens? Dirt-cheap Panasonic 45-200 on a m43 body? Or some old $10 FD mount 80-200 Macro? It is not like the skulls are running somewhere, it would be base ISO anyway.

Well, he did say that he researched practically all lenses manufactured during the last 30 years, and still arrived at the conclusion that the Sigma 400mm telemacro was the best one for the job, so presumably for him it offers something that other lenses don't.

Strictly speaking, they don't cut off information from the sensor. The sensor doesn't see colour to begin with; you have to add a colour filter array first, and that actually gives you less luminance information and also introduces false information due to interpolation.

In reply to:

Just a Photographer: Serious question.
But what is the benefit of a B&W only camera?
You can make B&W out of a colour image, but there is no way you can make a colour image out of a B&W only image..

I myself can not imagine that a B&W image sensor make so much difference that it outweighs to a color to monochrome conversion with the current state of technology and colour sensors that do 15.9EV.

Yes, no interpolation artifacts, and also better sensitivity, since there is no CFA filtering away all but a few wavelengths at each photo site.

In reply to:

zos xavius: This sensor looks like a decent improvement on recent 16mp BSI sensors of late. Less watercolor. Noise doesn't look horrible at 400 like the older sensors either. Its not fantastic or anything and I think a Pentax QS-1 would crush this on IQ, but hey for $175 its not bad at all.

I'm not so sure the sensor is different. It could just as well be improved noise reduction.

Photoman: "Sigma UK has said that the company's latest compact camera "

DP0 161.4mm/6.4” (W) × 67mm/2.6” (H) × 126mm/4.9”(D)
X100T 127mm x 74mm x 52 mm (5 x 2.91 x 2.05″)

Not what I call a compact camera...

I wouldn't personally call it a compact camera either, but that wasn't really my point. My point was that camera manufacturers and review sites use the term 'compact camera' in a specific sense, that most of us are familiar with, so there's really no point in quibbling about semantics in this case.
