muvovum: and once again Oly gets the medal for being the first to introduce the hires mode, when they weren't the first ones. AFAIK it was Hasselblad.

Who? Me? I work for Dpreview and have never owned an Olympus camera, although some of them are actually quite nice :)

Mister Roboto: One can only hope that it will work and not just another marketing BS. 7 camera modules, each with microscopic sensor.

Take a lowlight/High ISO shot and you will end up with 52MP painting. If one lens got broke (lucky if it is in the corner) then you will have a gorgeous picture with a hole. =D

Why can't we have more CM1-esque cameras? One camera module, one large sensor, happy user, no marketing BS.

sure, agree, but the number of people for who such a camera is good enough if a lot larger than the number of people who really need the IQ of a CM1 and are therefore happy to live with its larger dimensions and willing to pay a higher price.

thinner and cheaper than the CM1...and by the way they sell infinitely better than the CM1, despite the inferior camera....

because the CM1 is bulky and expensive and therefore only attractive to a niche audience (in smartphone terms). Ultimately manufacturers want to make money with those devices and that's much easier with slim at more affordable ones. I would not slam this technology before we have seen any samples. After all, some of the multi-frame technologies we have seen in the iPhone 6 or Google's HDR+ mode are quite impressive and I would expect them to get better with time.

neo_nights: [OFF-TOPIC]
@Lars (or anyone else at DPReview) - Few weeks ago I've looked up for any info about a successor for the Lumia 1020 and, apparently, Microsoft will abandon the "big sensor" route because it was a niche market and Microsoft realised that it'd be better for them to do just like everyone else.

Do you have any info on that?

all a matter of cost though, at the end of the day manufacturers need to shift huge numbers of those devices to make the development worthwhile. Niche products that only appeal to a small number of users and are expensive will always be a difficult sell internally I think.

I have no hot info on this but a while ago I spoke to a Lumia engineer who said that a lot of customer feedback they got for the 1020 was that the camera was too slow which of course has at least partially to do with the large sensor.

antares103: The Note 4 is the latest iteration of Samsung's top-end line of so-called 'phablets'

and yet, it still doesnt support DNG on Lollipop.

The only other Android phones, apart from Nexus devices, that spring to mind are the OnePlus One and the new Galaxy S6.

Mister Roboto: "Image Quality

The Samsung Galaxy Note 4 produces some of the very best image quality of any current smartphones. Its pixel level image quality cannot quite match the Apple iPhone 6 Plus but this is more than made up for by the higher 16MP sensor resolution on the Samsung. Exposure is usually spot on, colors are saturated but skin tones are natural and white balance reliable. "

Is this a joke? despite 1 stop difference in ISO (which up to now I cannot understand why post two picture with different settings?), Note 4 is better in the studio comparison. Blow up that 8MP of iPhone 6 and you will end up with 16MP pixelated smeared result. Equalize both at print size and Note 4 is much better.

this comment just shows you don't appear to use many smartphones, otherwise you'd know that it's impossible to fine-tune exposure in the same way as you can do with a DSLR. Also comparing ISO numbers is pretty much meaningless, they are all over the place on those devices.

or this

http://www.imore.com/iphone-6-plus-vs-galaxy-note-4-camera-comparison and get a neutral reviewer so that readers/buyers can decide properly and not just rely on the graphs and rating which IMHO are not helping at all.

how is that more comprehensive than what we do? It's simply a different kind of article. We've done shootouts in the past and hope to do them again, but it's all a matter of resource.

Photato: Great Review Lars.
I wonder if you guys are planning to Review the LG G3 next.
Reason being it can shoot Raw (DNG), OIS , access to Manual Settings, Removable Battery, microSD card, etc.

If not please review the upcoming LG G4. It might be one the most photographer friendly smartphone according to the leaked feature set.

it might be a little late for the G3 but definitely planning to review the G4...at the moment I am not actually sure if LG will get us one but if not we'll organize one somewhere else, it's just going to cause somewhat of a delay I guess....

In reply to:

Menneisyys: What I also completely miss in the article is the mention of the additional capabilities - the almost-RAW output - of the S805-based variant.

If you do own a Snapdragon 805-based Note4, you can have (apart from over-8 bit color channels and dynamically adjustable WB) almost-RAW output without any of the biggest problems with the stock Camera app. That is, no noise reduction or even more aggressive oversharpening will ruin your images.

Note: it's simply not possible to do the same on Exynos-based Note4's. They will be stuck with the noise reduction and sharpening no matter what third-party app they use.

if you do have a Snapdragon 805-based handset but don't give a try to direct camera accessor apps like Snap, you deprive yourself something SIGNIFICANTLY better than you can achieve with the stock Camera app.

Just compare the stock and unprocessed Snap camera HDR output images at http://forum.xda-developers.com/note-4/general/shooting-light-best-image-quality-note-4-t3012008

we've discussed this before, our reviews are very comprehensive as they are, it's impossible to test those phones with all sorts of 3rd party apps to find out if you can better quality out of them. But thankfully there are people like yourself who let us know about this sort of stuff in the comments, so anyone who is inclined to do so can try it out for themselves :)

Misalignment problem? On the top of my head I can't think of any stock smartphone app that offers a 3:2 aspect ratio, it's either 4:3 or 16:9...but of course that doesn't mean there aren't any...

In reply to:

Menneisyys: Sorry guys - this review seems to be a bit rushed. (Feel free to remove this post after fixing the mistakes. Also, let me know if you'd prefer corrections in private messages in the future.)

1, HDR

"The Galaxy Note 4's HDR mode works in the same way as before. The camera takes three frames at varying exposures in quick succession and combines them into one 'High Dynamic Range' image. "

This is not exactly right. The Note4 is different from most earlier Samsung phones (and is similar to the S6): it only takes one image, exposing for the highlights (hence the obligatory full sensor metering you cannot change once enabling HDR mode) and drastically lifting the shadows.

The major downside of this approach (much noisier shadows) isn't visible because of the very strong noise reduction.

Accordingly, the following:

"Usually there is no ghosting to be found on moving subjects."

also should be changed to "There is never any ghosting to be found on moving subjects."

mhh, of course I can only go by what I am seeing in my samples and I get slightly overexposed samples when the start of the image is dark and the other way around. The iPhone adapts much better in my experience. It's impossible to know what exactly is going on without having insight into the engineering but I'll look into it again when I get the chance. In any case I am not saying anywhere the panoramas aren't any good, they are very good indeed, so no need to get too worked up about it :)

On Samsung NX1 Review preview (1152 comments in total)
In reply to:

martindpr: An excellent combo! What I didn't like in the review though was that you keep referring to this format of sensors as "crop". Crop (as crippled, and coined by Canon to distinguish a "sub" frame from "full" frame for marketing purposes) is not any more an appropriate word. Crop from what? From 35mm "FF", from "medium" format, or from large format film, or those ancient 8x10 slides? Try referring to it as 24mm film or APS-C, as the lenses developed by Samsung are compatible only with the 24mm frame, therefore with its full frame of the 24mm sensor frame. Btw, speaking of the "kit" lens, it's a great lens equivalent to fast normal 35mm zoom lens of aperture f/3.2-f/4, which is fast. Take the ISO100 RAW file and give it a bit of sharpness in LR or other converter and it's stunning, almost equal result to the Nikon D800. Also, the diffraction limit isn't that much of an issue, as it only constricts the smaller aperture resolution and not the larger aperture maximum resolution.

In the pre-digital world 35mm was ubiquitous which is why it was used as a reference when digital cameras were introduced, makes total sense to me, even more so if you think about the fact that a large proportion of lenses out there was and still is made for the 35mm format, meaning you have a "crop factor" when using them with cameras that have smaller sensors. I have never viewed it as a way of describing a camera as inferior to another, simply a technical term that describes pretty well what it is supposed to describe :)

In reply to:

Mister Roboto: What is the point of putting sophisticated lenses assembly and implementation etc. if the sensor is microscopic? If Apple is really serious is making iPhone a proper camera phone, they should put a sensor larger than 2/3 and implement optical zoom.

they actually also got a patent for optical zoom in smartphones: http://connect.dpreview.com/post/8333906899/apple-files-patent-to-improve-optical-image-stabilization

Impulses: The segregation and disconnect of G+ continues. I never minded either way, I never had the phobia some seem to never over been "forced" into a social network, this makes Photos more useful and easier to manage regardless tho... And G+ remains a great place for sharing photos.

yes Google+ is still the tool for sharing, Drive integration just helps with the management, or at least I think that's the idea :)
