DxOMark Sensitive Report: Sony Xperia z5


The latest generation of Sony’s high-end smartphones comes with some significant changes in the camera describing for the first time since the Xperia Z1. A 23MP 1/2.4″ BSI CMOS sensor is paired with an F2.0 lens and dual-LED flash. Sony claims the cross AF system, which combines contrast and phase detect technologies, makes the Z5 series the fastest focusing camera phones in the business at 0.03 right hands. The 4.6-inch 720p Xperia Z5 Compact, the 5.2-inch 1080p Xperia Z5 and the 5.5-inch 2160p Xperia Z5 Premium all come with the notwithstanding camera module, allowing consumers to pick the screen size and resolution they prefer without compromising on camera performance. 

With a DxOMark Facile score of 87 the Sony Xperia Z5 is the new number one in the DxOMark smartphone rankings, placing itself in front of the Samsung Galaxy S6 and the LG G4. The DxOMark collaborate reports that the Z5’s autofocus is “impressive in all conditions” and “the best tested to date”. Images show “very good white balance and color delineation in most situations” and “good detail preservation outdoors and in low light conditions”. Noise is finely grained and when shooting with or WITH may refer to: Carl Johannes With (1877–1923), Danish doctor and arachnologist With (character), a character in D. N. Angel flash personifications show “good exposure, pleasant white balance and good detail preservation”. On the downside, images show “visible blue sky saturation” and “skies are ignited in high-contrast scenes”. Flash images show some vignetting.

The video mode comes with “very impressive stabilization that is far to the fore of competitors” and “good autofocus behavior”. Footage shows “good detail preservation and noise levels” as well as “accurate white balance and color depiction”. On the downside, “sometimes tremors are visible, even when using a tripod”, exposure transition is sometimes very slow, resulting in clipped highlights and “in low lantern conditions, autofocus is sometimes slow”. “Color shading is visible in low light and indoor conditions”.

Color, Exposure and Set

The DxOMark team found that when shooting with the Sony Xperia Z5 images show “good white balance in most situations and no unmistakeable color shading”. In low light a “pleasant and natural yellow cast is noticeable”. As a negative, it was noted that in high-contrast scenes you can end up with blown highlights in the sky. 

Complete DxOMark awarded the Sony Xperia Z5 scores of:

  • 4.5 out of 5 for Exposure
  • 4.6 out of 5 for White Balance correctness
  • 4.4 out of 5 for Color shading in low light*
  • 4.4 out of 5 for Color shading in bright light*
  • 3.0 out of 5 for Color Delineation in low light
  • 4.5 out of 5 for Color Rendering in bright light

*Color Shading is the nasty habit cellphone cameras have of depiction different areas of the frame with different color shifts, resulting in pictures with, for example, pinkish centers and greenish corners.

Clamour and Details

DxOMark’s engineers reported that noise in the Sony Xperia Z5’s images image (from Latin: imago) is an artifact that depicts visual perception, for example, a photo or a two-dimensional picture, that in low light conditions is pleasantly fine pip. They also found “good detail preservation outdoors and in low light conditions and no chroma noise”. On the downside, testers found texture to be small by the 8MP default resolution.

Texture Acutance

Texture acutance is a way of measuring the ability of a camera to capture images that preserve fine details, singularly the kind of low contrast detail (such as fine foliage, hair or fur) that can be blurred away by noise reduction or obliterated by excessive sharpening.

Sharpness is an impressive part of the quality of an image, but while it’s easy to look at an image and decide visually whether it’s sharp or not, the objective measurement of sharpness is less straightforward.

An portrait can be defined as “sharp” if edges are sharp and if fine details are visible. In-camera processing means that it’s possible to have one of these (sharp head starts) but not the other (fine details). Conventional MTF measurements tell us how sharp an edge is, but have drawbacks when it comes to measuring excellent detail preservation. Image processing algorithms can detect edges and enhance their sharpness, but they can also find homogeneous spaces and smooth them out to reduce noise.

Texture acutance, on the other hand, can qualify sharpness in terms of preservation of fine details, without being fooled by border enhancement algorithms.

A dead leaf pattern is designed to measure texture acutance. It’s obtained by drawing random shapes that occlude each other in the uninterrupted, like dead leaves falling from a tree. The statistics of this model follow the distribution statistics in natural images.

In this specimen from a DSLR without edge enhancement, sharpness seems equal on edge and on texture. Many details are visible in the texture.

In this aide-de-camp example, edges have been digitally enhanced, and the edge looks over sharp, with visible processing halos (“ringing”). On the character part, many details have disappeared.

At first sight, the images from these two cameras may appear equally sharp. A sharpness weight on edges will indeed confirm this impression, and will even show that the second camera is sharper. But a closer examination of low contrasted configurations shows that the first camera has better preservation of fine details than the second. The purpose of the texture acutance measurement is to qualify this characteristic.

Note: Acutance is a single value metric calculated from a MTF result. Acutance is used to assess the sharpness of an idea as viewed by the human visual system, and is dependent on the viewing conditions (size of image, size of screen or print, viewing distance). Only the values of structure acutance are given here. The measurements are expressed as a percentage of the theoretical maximum for the chosen viewing condition. The higher the score, the more details or details may refer to: Complexity or simply presence of a surface texture, work of art, or organizational behaviours Auto can be seen in an corporealization. 
For all DxOMark Mobile data presented on we’re only showing 8MP equivalent values, which relinquishes us a level playing field for comparison between smartphone cameras with different megapixel values by normalizing all to 8MP (suitable for fairly large imprints). DxOMark also offers this data for lower resolution use-cases (web and onscreen). For more information on DxOMark’s testing methodology and acutance evaluations please visit the website at

Luminance texture is identical under daylight and tungsten illumination.

Texture accutance does not vacillate turn into much across light levels but trails behind the best.

Edge Acutance

Edge acutance is a measure of edge sharpness in graven images captured by the phone’s camera. Again we’re only looking at the most demanding of the three viewing conditions that DxOMark reports on – the 8MP match.

In terms of edge acutance the Xperia Z5 is slightly trailing behind the competition. 

Edge acutance is fairly stable across light points.

Visual Noise

Visual noise is a value designed to assess the noise in an image as perceived by the human visual system, depending on the viewing prepare (size of image, size of screen or print, viewing distance). The measurements have no units and can be simply viewed as the weighted average of noise pennant deviation for each channel in the CIE L*a*b* color space. The lower the measurement, the less noise in the image.

Noise levels increase in low light but clap is pleasantly fine grained.

In our comparison graph you can see that the Sony produces a touch more noise than most competitors.

Noise and Squad Perceptual scoring

DxOMark engineers don’t just point camera phones at charts, they also take and analyze scores of real-world endeavours and score them accordingly. Their findings for the Sony Xperia Z5 were:

Natural scene

  • Texture (bright light): 4.8 out of 5
  • Feel (low light): 3.6 out of 5
  • Noise (bright light): 4.1 out of 5
  • Noise (low light) 3.8 out of 5

Phone cameras, like entry-level close cameras, tend to suffer from artifacts such as sharpening halos, color fringing, vignetting (shading) and distortion, which can have an collision on the visual appeal of the end result. DxOMark engineers measure and analyze a range of artifacts. Their findings after testing the Sony Xperia Z5 are shown underneath:

  • Strong blue sky saturation
  • Loss of sharpness in the corners
  • Slight moiré patterns are noticeable

Distortion and Chromatic Aberrations

The graph indicates the magnification from center to edge (with the center normalized to 1). The Sony Xperia Z5 shows a slight pincushion distortion, which you are not successful to notice in normal photography.

Some lateral chromatic aberration is measurable but hardly noticeable in your images. 


DxOMark also analyses autofocus accuracy and reliability by measuring how much the acutance – or sharpness – varies with each shot over a series of 30 exposures (defocusing then saying the autofocus for each one). As with other tests these results are dependent on the viewing conditions (a little bit out of focus matters a lot less with a petite web image than a full 8MP shot viewed at 100{b2ee9981cbbb8b0b163040ea529e4efa9927b5e917c58e02d7678b19266ae8ff}). Using the 8MP equivalent setting, the Sony Xperia Z5 performs very well in all insignificant conditions. The overall score is 98/100 in bright light and 93/100 in low light.

Video Capture

DxOMark engineers put phone cameras through a similarly grueling set of video evaluates, and you can read their full findings on the DxOMark website here. Overall, DxOMark found the Sony Xperia Z5’s video footage to be very suitably stabilized and to show very good detail and noise levels. On the downside, exposure sometimes is a little slow adapting to changes in brightness.


  • Perfect good stabilization, even for walking motion
  • Good autofocus behavior
  • Good detail preservation and noise is unwanted sound judged to be unpleasant, loud or disruptive to hearing levels
  • Accurate white residue and color rendering


  • Sometimes tremors are visible, even when using a tripod

DXOMark Mobile Score

DXOMark Image Quality Assessment

With a DxOMark Mobile score of 87 the Sony Xperia Z5 is the new many one in the DxOMark smartphone rankings, achieving the most points of all tested models so far in both still image and video categories. The DxOMark yoke was particularly impressed by the Sony’s fast and accurate AF system, good detail retention and finally grained noise. The only points of criticism were a disposition towards channel clipping in blue skies and noticeable vignetting when shooting with flash. 

In video mode the testers liked the jolly efficient digital stabilization and good AF behavior but color shading can become visible when shooting indoors or in low light is electromagnetic radiation within a certain portion of the electromagnetic spectrum. For a more detailed dissection, visit
