bluevellet: I wonder what the Panasonic chip is for.

The camera makers that aren't also semiconductor/electronics companies probably make the same things they did back when cameras didn't have sensors, image processors or LCD screens. Most of them didn't make film, but were still regarded as camera makers.

maksa: The K-S2 is the predecessor, isn’t it?

No, Ricoh has stated that there's two parallel model lines. There's the regular DSLRs with the K-500 as budget entry-level, the K-50 as advanced entry-level, and the K-3 as enthusiast-level model, and then there's another line aimed at a different audience, with the K-S1 at the low end and the K-S2 as a more advanced option.

This is from an interview on Imaging Resource:

"So we have the K-series, and now the K-S series. [The K-S series], we have categorized as the innovation series. We are not [talking about it that way] outside [the company], but internally we think the K-series is for core lines like the K-3 -- the real blood or DNA of Pentax. And then the K-S1 or K-S2; with these models we wanted to attract the users who had not had interest in Pentax before, they're new."

It's doubtful if there's a need for two parallel lines of DSLRs, and maybe Ricoh now has decided to merge the two?

No, the K-50 is the predecessor. The K-S2 (and the K-S1 below it) is part of a parallell line of models targeted at a different customer.

jim bennett: "Now that the D5 has 20.8 megapixels a shutter speed of at least 1/2000th is needed to freeze most fast moving sport. What many people don’t realise is that the more megapixels you have the faster shutter speeds necessary to freeze the same action. "
This is the first time I have heard this. I have always been under the impression that it was about having a high enough shutter speed in relation to the focal length of the lens, and taking into account any crop factor that changes the equivalent focal length, but needing a faster shutter with more megapixels is news to me.

It's nothing strange if you think about it. It's not that you get more motion blur because you have more megapixels, but the blur that you do get is more visible (at the pixel level) because it's covered by more pixels. It's the same reason why some lens aberrations are more visible on high res cameras, simply because there are more pixels to capture them.

David Kinston: In our family there are 3 different recent Nikon cameras, from the D7200 to the D750. Tamron, Sigma and Tokina lenses as well as Nikon. Never any issues.

Plainly CANON is the problem! They like making life difficult for their competitors - and we photographers are the ones suffering.

It's not just Canon. Nikon is notorious for changing communication protocols, and making life difficult for lens makers that rely on reverse engineering. It's a similar situation with third-party batteries.

However, no manufacturer is obliged to ensure that third-party products are compatible with its cameras, unless they have an official partnership. It's up to the companies doing the reverse engineering to keep up with any changes that may be made.

reptile9985: SilkyPix not only renders better raw developing with pixel shift on, but there's a huge difference even in normal mode compared to acr.
I suggest you guys to re-do all the studio scene tests with SilkyPix as well both with and without pixel shift!

@Muqdad

Yes, but many photographers aren't really interested in knowing which combination of camera and software produces the best results. They want to know which camera produces the best results within their current workflow, with the software they're already using. And for the majority of users (but far from all), that workflow is based around ACR.

Using different converters for different cameras doesn't really provide a more useful comparison than using the same converter for all. Ideally, a comparison should show the results from all the major raw converters (ACR, DxO, Capture One, etc.) as well as the software that comes bundled with the camera. But if only one is to be chosen, eg. because of time constraints or limited resources, then the one that has the most users is the logical choice.

On article Nikon offers free battery exchange for D500 owners (96 comments in total)
In reply to:

Toccata47: Is this the third high end release that has either been recalled or required field service, in a row?

If I've understood this issue correctly, it's only when used in the D500 that the older version of the battery doesn't work according to specs. So it's not a question of lacking backwards compatibility, but rather a question of not being able to guarantee forwards compatibility.
Why would you be eligible for a replacement if you don't own the camera model that causes the problem?

To a large degree, I agree. We are basically never comparing the cameras themselves, but the way their files are treated by the raw converter. However, by using different converters for different cameras, we're adding yet another variable, and we really don't have a common baseline at all. We simply don't know to what extent we're comparing cameras and to what extent we're comparing raw converters.

If the intention is to just show the best that a camera is capable of, rather than comparing the capabilities of different cameras (or sensors, which are what many gearheads really seem to be interested in), then your method is certainly preferable. But a meaningful comparison requires the elimination of as many variables as possible.

EcoR1: For god sake dpreview, stop using the name "FE-mount". Now! There is no FE-mount, there is only E-mount. These lenses mentioned in this article are full frame E-mount lenses, not FE-mount-lenses. By using the non-existent name, you give impression to people that these lenses are somehow incompatible with a smaller sensor E-mount cameras like a6300. If you go and read some cameraforums you can already see that some people think that there are two different mirrorless mounts made by Sony. Stop confusing people!

I agree with that. It's one mount, but two series of lenses made for different sensor sizes. It's just like the A-mount, and no one talks about that as if it's two different mounts. Same with Nikon's F-mount. Canon is the odd one out, with EF and EF-S, where the compatibility only goes one way.

"The bundled software is the baseline."

But how many people actually use the bundled software? And most people who own cameras from different brands probably prefer a common workflow for them all, rather than using different software for every camera.

"but then isn't that what we're all after: to get the best, highest quality picture our camera is capable of producing?"

There is no single raw converter, or conversion setting, that will produce the best picture quality for every camera, so that would require a lot of testing to find the optimal converter, and the optimal conversion settings, on a case-by-case basis. And wouldn't we then be comparing raw converters just as much as we'd be comparing cameras? It seems to me that choosing the most popular raw converter, and using standard conversion settings, is still the best method to level the playing field, imperfect as it may be.

mais51: My D800 came with a EN-EL15 Lion01. If I buy a D500 today would I be able to exchange the old battery for a new generation one ?

Yes, that's correct.

In reply to:

Jacques Cornell: I wish DPR would define "dual camera". Are we talking about two sensor+lens units on the back of the phone, or just one sensor with two lenses or focal lengths?

Since a camera module contains both a sensor and a lens, "dual camera" means two sensors and two lenses.

On article Lens shootout: Sony RX10 III destroys the competition (483 comments in total)
In reply to:

rrccad: Nice review of the optical qualities.

however this is missing some points here for both the panasonic and the canon that should be highlighted and it's a disservice to both that they are not.

both are significantly lighter than the RX10 III (200-300g), they cost significantly less and they are much smaller to boot.

that obviously plays into the optical qualities illustrated here.

"The Canon PowerShot G3 X's trump card has been trumped." sounds like something that you'd expect from SAR.

I look at the G3X as a compromise between portability and focal length - the RX10 III certainly is not in the same category as the G3X as far as portability, or even the FZ1000 as well.

"magnesium weathersealed body vs plastic non weather sealed."

According to Canon, the G3X has rubber seals and a magnesium alloy body.

In reply to:

Ocolon: I don’t need an action cam but it’s interesting to see the return of a 1/2.3" sensor with 8 megapixels due to the demand for 4K. Maybe this will find its way into more products, making people looking for lower resolution point and shoot cameras happy again?

"You can capture all the photons you want perfectly"

Not really, because there's always photon shot noise, which is an inherent property of light itself, and in many cases, its impact is larger than that caused by read noise or thermal noise.

JosephScha: The new GF8 is still about $500, should have been included. And the G7 when on sale sells for $599, I wonder how close to $500 qualified.

The G7 was included in the $500-$800 roundup.

In reply to:

Bob1975: Doesn't the D7200 use a Sony sensor. If it does is the camera really a Nikon? The only thing nikon about it is the body when the heart of the camera is made by a different company.

Chipworks does teardowns, and looks at the serial numbers and other markings on the components.
It seems to me that DxO is just guessing that it's a Sony sensor based on the pixel count.

LawDude: If Samsung had offered h.264 as an alternate codec, and built a smart adapter so people could migrate their EF/EF-S lenses with full AF functionality (while Samsung developed their own lens ecosystem), they could have dominated the market with the NX-1.

@photomedium

Yes, you're probably right. Point taken.

The same conspiracy that included the K-S2 in the $500-$800 roundup, I presume?
