Test iPhone 8 Plus
Par Compared to the iPhone 7 Plus, the evolutions are therefore quite small: the 8 Plus integrates a 28 mm f/1.8 lens associated with a 12 Mpx sensor (1/3"/photosites of 1.2 µm), and completes this first module with a second one equipped with a 56 mm f/2.8 lens, also associated with a 12 Mpx sensor (1/3.6"/photosites of 1 µm). As for the iPhone 7 Plus, only the wide-angle module is here equipped with optical stabilization. Note that while Apple praises the merits of a "larger and faster sensor" and strangely mentions "deeper pixels", the photo sensors used from one generation to another have exactly the same definition and physical size.
advances in image processing can nevertheless be expected, thanks in particular to the adoption of the A11 Bionic mobile chip, which features a processor dedicated to this task. In video mode, capture is now possible in UHD 2,160p at 60 fps, and in Full HD 1,080p at 240 fps in Slow Motion mode.
front photo module seems once again to be the same as the one that equips the iPhone 7 and 7 Plus: a 32mm f/2.2 combined with a 7MP sensor and allowing video capture in Full HD 1080p 30 fps and in HD 720p up to 240 fps.
Prise and main
Ergonomics and design
lack of evolution of the iPhone 8 Plus is also clearly noticeable in its physical resemblance to the 7 Plus, which itself already looked a lot like the two previous generations of Apple smartphones. If innovation is not the strong point of the 8 Plus, we find a solid aluminum construction, whose curves allow a good grip despite the imposing size of the terminal.
On also has IP67 certification, which ensures resistance to immersion in a liquid for up to 30 minutes and up to 1 m in depth. Contrary to the competition running on Android, however, it is advisable to forget any idea of micro-SD port to extend the storage space.
Ne unfortunately lacks the optimization work done on some recent smartphones, the 5.5-inch (≈14 cm) Full HD (1920 x 1080 px) IPS LCD screen (≈14 cm) achieves an occupancy rate of 67% of the smartphone's front panel. Nevertheless, its 401 dpi resolution is sufficient for the majority of uses, while its maximum brightness of 590 cd/m2 and light reflection rate of only 9% ensure very good readability.
Avec a delta E at 1.6, the colorimetry of this screen proves to be very good, while True Tone technology allows automatic adjustment of the color temperature according to the ambient light conditions. Only the contrast ratio at 1200:1 is somewhat disappointing.
Chez In Apple, the shortcut to directly access the app takes the form of a lateral swipe of the finger from the terminal's unlock screen.
Tout as with the iPhone 7 Plus, the volume buttons on the 8 Plus can be used as a shutter release. Being located on the left side of the device when held vertically, they can be accessed with the thumb of the left hand or the index finger of the right hand depending on the direction in which the smartphone is held when it is positioned horizontally.
Apple has always advocated a simple user interface that is accessible to everyone, and the shooting parameters offered here are the bare minimum: only the control of the flash and self-timer, the selection of a few filters, as well as the choice between the various shooting modes (Photo, Portrait, Square, Pano, Video, Speed Up and Slow Down) are possible. Once again, we applaud the clarity of the interface, but regret being limited to so few settings.
Peu convincing at the time of our test of the iPhone 7 Plus, the Portrait mode is equipped with a feature allowing to vary the lighting of the photographed subject and its background, when shooting or during the retouching phase. While image processing algorithms now seem to do a little better in terms of the delineation between sharpness and blur, the results are still highly dependent on the complexity of the scene, and can sometimes be catastrophic. This was the case when we used the Scene Lighting and Mono Scene Lighting modes.
Bien that relatively well thought out, the retouching interface proposed by Cupertino lacks tools to replace an app dedicated to this task. Also note that it is still impossible to capture or retouch RAW format photos using native iPhone 8 Plus apps. You must therefore use a third-party application, such as Lightroom for Mobile, to be able to take photos in DNG format and take advantage of their flexibility during the retouching phase.
Qualité from image
L As a native application for Apple smartphones that does not offer manual settings, we tested the terminal's photographic capabilities under lighting conditions simulating daylight (250 lux illuminance and 6,500 K color temperature) and in low-light conditions (3 lux illuminance and 3,200 K color temperature).
À As a reminder, the photo modules of the iPhone 8 Plus are both equipped with a sensor with a resolution of 12 Mpx. The one that comes with the wide-angle lens has a size of 1/3" (1.2 µm photosites), while the one with the longer focal length has a size of 1/3.6" (1 µm photosites).
Tailles relative to the different sensor formats.
Traitement from image
Force is to confess that our laboratory is not the iPhone 8 Plus' favorite terrain. We said of its predecessor that it was not a master of precision, and while the 8 Plus delivers pleasantly high-contrast images at wide-angle, the resulting photographs are less accurate than those from the best wide-angle modules of 2017 - we're thinking of the HTC U11, LG G6 and OnePlus 5. In addition, the white balance is a little too hot, which contributes to the aesthetics of the iPhone in real-life shooting situations, but reveals a lack of fidelity in the laboratory.
Bien that, as in our test of the iPhone 7 Plus, we judge the level of detail transcription to be very disappointing when the module with a standard focal length is used, we welcome the homogeneity of the colorimetric rendering. The lack of precision is unfortunately even greater in low-light conditions, where the smartphone performs a digital zoom from the wide-angle module, rather than using the normal focal length and its smaller aperture. The resulting poor image quality is then clearly noticeable.
Face to concurrence
Mesuré here at the leading edge of wide-angle detail transcription (OnePlus 5) and using a normal focal length (Samsung Galaxy Note 8), the iPhone 8 Plus reveals its limitations here.
iPhone 8 Plus allows the recording of videos in 2,160p 60/30/24 fps, 1,080p 60/30 fps and 720p 30 fps, with either of the back photo modules. A mode dedicated to slow-motion shooting allows recording in 1080p at up to 240 fps. Remember that only the wide-angle module benefits from optical stabilization.
In UHD 2,160p, the level of detail reproduction is honorable, but lower than the master of its kind, the Asus ZenFone Zoom S. Derolling shutter effects will be virtually non-existent regardless of the photo module used. The autofocus is effective at the wide-angle, but hesitant when using the longest focal length.
Sans surprisingly, the iPhone 8 Plus is an almost exact copy of the 7 Plus as far as its photographic capabilities are concerned: the combination of a wide-angle module and another module with a longer focal length allows for a good shooting comfort, even if the second APN disappoints us as far as the level of details it allows.
Apple's seal is clearly perceptible at every shot: although it does not offer manual adjustments, the simple and uncluttered interface is particularly effective, while the aesthetics of the photos captured lack neutrality, but are pleasing to the eye.
Doté in addition to a quality screen and IP67 certification that ensures a certain water resistance, the iPhone 8 Plus therefore has a solid list of strong points, but limits its photographic progress to slightly more powerful image processing than its predecessor. It's a shame that some of the new features are reserved for the iPhone X - such as a second photo module with a larger aperture and optical stabilization.
Si we once again recommend this new iteration of the iPhone to photography enthusiasts who want to rediscover the ergonomics and aesthetics of Apple's handheld devices, as the photographic evolutions compared to the 7 Plus seem too limited to justify the transition from one generation of smartphones to the other. And if we dare to compare the iPhone 8 Plus to the competition running on Android, let's admit that the Samsung Galaxy Note 8 seems to be better equipped: its manual mode and the optical stabilization of its second photo module give it the edge.
