    DxO Labs has published an in-depth iPhone 7 camera review, calling it "a very solid evolution over the iPhone 6s" after extensive testing. The single-lens smartphone achieved an overall DxOMark Mobile Score of 86, topping the iPhone 6s by two points but trailing the Samsung Galaxy S7 Edge and five other devices.

    iPhone 7 has a wider DCI-P3 color gamut that allows for more vibrant colors compared to the traditional sRGB standard. The photo on the right, for example, rendered using the DCI-P3 color space, has richer reds displayed compared to the photo on the left rendered using the traditional sRGB color space.

    DxO said the iPhone 7 offers great exposures with wide dynamic range, accurate white balance and color rendering, and good detail preservation when shooting outdoors in bright daylight. The test noted some exposure failures, such as overexposed highlights, but said the instances of these were minimal.

    The review also awarded high marks for the iPhone 7 camera's excellent corner-to-corner sharpness, reduced noise, and accurate color representation. DxO shared the photo below as an example of what it called excellent White Balance. The review said, in some cases, a barely noticeable green cast can appear.

    Additional photos and test results can be found in the DxOMark review. DxO has analyzed the image and video quality of over 9,000 cameras, lenses, and mobile phones, and its tests are generally respected within the industry. The company also sells some consumer-facing products like the DxO ONE camera.

    DxO said its iPhone 7 Plus camera review is coming very soon.

    Finally good to see a 7 camera review. All the ones I've read seem to be about the 7+.

    Let's see what the Plus scores. I am very interested in seeing if two lenses work together to make a better image.

    This is a reputable review site and there are 7 android phones ranked higher.

    That's quite some definition of "only" you have there, MacRumours.

    They have gone to such extraordinary lengths to compensate for the smaller sensor, imagine how good the image quality would be if it were larger? I'd take a slightly thicker phone or more pronounced camera bump for this alone.

    Some notes from the review:

    The HTC 10, which is currently our top-rated phone camera, and therefore still the gold medalist, was clearly designed to optimize image quality, using a large 10mm phone thickness (“Z” dimension), with an f/1.8 aperture, and a sensor whose area is 60% larger than that of the iPhone 7. This gives the HTC an image quality advantage over the iPhone 7, as confirmed by their respective DxOMark scores of 88 for the HTC 10 and 86 for the iPhone 7, but the HTC 10’s advantage comes at the expense of a thicker handset.

    Samsung also made an interesting choice by managing to pack into an equally-thin handset an f/1.7 lens and a sensor whose area is 35% larger than the iPhone 7’s sensor. This combination is what gives the Galaxy S7 Edge its DxOMark score advantage of 88 points, compared to 86 for the iPhone 7. Interestingly, Samsung chose to use a lens with a wider field-of-view to reduce the thickness of the Galaxy S7 Edge, a design choice that’s in the same direction as Sony smartphones, which also combine a larger sensor with a larger field of view.

    Result: Thinness AND optimal image quality
    While Apple’s flagship phones may have a smaller sensor than their competitors from Samsung and HTC, Apple has incorporated a variety of innovative technologies to create a compelling smartphone experience in a very-thin form factor. This includes high-performance lens design, efficient sensor electronics, built-in optical image stabilization, multi-image synthesis on a high-performance image processing chip, and an advanced image processing pipeline.
    So sensor size is a big factor in final image quality. The above suggests that the iPhone camera system may actually have better technology, but the smaller sensor results in a slightly lower score at the end of the day. Equalize the sensor size and then you can truly do an side-by-side comparison of image-processing by each phone.

    This also suggests that the iPhone 7 Plus may end up with superior results over every other smartphone, due to its double-camera system (essentially double the effective sensor size).

    I think we'll be having to wait till Apple releases that feature unless dxomark wants to use beta firmware. One thing that has irked me about my wife's 7+ is the lack of ois on the tele lens...
    Also, I don't think having 2 cameras will necessarily improve the 7's image quality as the tele is used to take the pic while the wide angle is used to help make the blurred background.
    But overall a good review as the plus shares the same wide angle camera as the 7

    Good review from DXOMark, but how can they not of uplifted the colour score from the 6s+ to the 7? The camera has gone from sRGB to DCI-P3, so surely even a nominal colour score increase should be reflected there? And if there's a an uplift in that score, it uplifts the whole score which may actually even put it technically higher up the rankings...

    Unless the argument is that you can't benefit from DCI-P3 unless it's supported by the viewing interface - but that's surely not a scorable consideration of the camera?!

    As a professional photographer, I've followed DxO's reports for years. Perhaps this report will quiet down the haters.

    "such as overexposed highlights, but said the instances of these were minimal."

    Everyone is after a perfect smart phone camera equal to DSLR's. which is not gonna happen.. Gap is closing, but users demand more... in a phone...

    If your that determined, then u look like a professional, in which case get a DSLR, why are u using smart phone to take "professional" shots ?

    No professional photographer would leave their expensive DLSR at home for lightening shots..

    Great review, I wonder If Apple TV 4 supports wide color gamut (my tv does) trough airplay photo sharing...

    doubtful. I think it is still 8-bit. Next year we should get an update for 10-bit support, WCG, and 4K HDR.

    I think every iPhone I have owned took decent photos outdoors with a lot of light.

    The low light photos tend to be most disappointing to me.

    Anyone know how the different iPhone 7 models do in low light?

    Without aim, there's no achievement. Hence, the pc has stagnated and the mobile era has accelerated.

    So-so (regular 7 here). There are improvements from the 6S in some low light scenarios, and in others no real difference. It also causes the phone to over-expose or blow things out more often in good lighting. Such is life for any phone trying to let in more light to compensate for low-light shots.

    Thanks,
    I one of the main reasons I got a 6s Plus was for the better camera. I was a little disappointed in the camera and the size.

    It is hard to use 1 handed. Hopefully the iPhone 8 will have a decent camera in a smaller size.

    As for my photos, almost all of them are taken inside with normal light for a living space. They do not look the best and I was hoping for some improvement with this model.

    That's not a bad score from DxOMark, what a difference a handful of years make. Shows you how bad the iPhone 4's camera was to have scored 50 :D

    Looking forward to see what they make of the 7 Plus. If history continues it should be a couple points above the standard 7 at least. Time will tell.

    I was wondering if my Samsung KS7000 (or any other 10bit dci-p3 tv's) could correctly display the photos if copied to a pendrive and plugged into the set. I checked the jpg's and they have Apple Wide Color Sharing Profile as Color space so perhaps it's Apple's owwn format and not a so-called 'standard'.

    I think that scenario is probably where there is a lot of improvement - where there's some light in the picture, it's just not ideal light. In those photos, the noise level is lower now, and the photos look brighter in general.

    I took some pictures at a concert and I was surprised that I could actually see detail on them. Usually they would be colored blobs because the low-light performance was so bad. But the 7 really hit the mark there!

    WCG is actually supported by tvOS 10, app developers have to enable the library to make use of it. In my testing though, neither the interface nor apple's own apps are currently in an extended range.

    How can a side by side comparison of a photo taken in the sRGB colourspace and a photo in the wide gamut DCI-P3 on a website be correct? That top image is an sRGB image making the comparison BS. Both of the photos are sRGB.
