For Samsung's mid-range series — the Galaxy A's — there's a new harbinger of the Galaxy S10, one that brings three cameras and marks Samsung's foray into a world that was formerly explored only by Chinese manufacturers. With the newest Galaxy A7, the handset has been confirmed to ship with three shooters on the back and one in the front. The rear optics will include 24 MP, 8 MP and 5 MP while the front shooter brings a solid 24 MP sensor for bringing out every curve and edge in your face.
There's more to the picture than meets the eye however. The multi-camera trend was started as a way of addressing what DSLRs have that smartphones lack: big, bulky sensors. Megapixels aren't everything as light intake, color reproduction and shutter speeds are all accountable in the turnout of any given image you capture; for smartphones, it's just not smart to put a full-size lens and sensor suite on board due to size constraints. Instead, the answer was the break up the many roles of camera hardware into, well, different cameras.
On the back, each sensor does its own thing:
- The 24 MP camera is the primary shooter and serves to deliver high-resolution shots.
- The 8 MP camera aims to add wide-angle functionality, which allows you to pick up more scenery inside a single picture.
- The 5 MP camera is for depth perception and probably also helps out with light intake.
The 24 MP camera is speculated to use "pixel-binning", which was used on Huawei's P20 Pro to combine the information captured on all four of its sensors and yield a higher quality image as a result. As many know by now, the P20 Pro has been awarded as having one of the best camera arrays in the smartphone world, and it owes to the faux-DSLR setup that relies on this very same pixel-binning technology that Samsung is probably incorporating in the newest A7. It's worth noting that this technology existed in its nascent form with the Galaxy S8+ and Galaxy Note 8, eventually working its way into the 9-series flagships and will now graduate into the S10 with Huawei's approach to camera tech incorporated.
As trends would have it today, the selfie camera in this handset is decked out with a 24 MP camera that brings Selfie Focus, an LED flash that can be controlled by the user, and Pro Lighting for that ideal look that hides blemishes while bringing out the nicest features in your face. Scene Optimizer was also included, and thankfully, there's no AI involved in determining how any of these features are conducted — rightly so as some horrifying results have been noted when computers are left to judge what makes a person's face stand out best.
For a phone that rests along the mid-range fault line, it's pleasing to see such emphasis on camera quality, and the processing prowess that the Korean giant will add to the mixture should no doubt do a fine job at handling everything else you ask of the device. Just behind the A-series are the Galaxy J's, and ahead of it are the Galaxy C's followed by the famous S-range. Putting that in perspective, you can imagine what kind of camera technology we'll see in the S10 when it's finally revealed.
Other specs to look out for in the A7 (2018) include:
- 6-inches of AMOLED goodness
- 1,080 x 2,220 resolution (FHD+)
- 4 GB of RAM with an octa-core 2.2 GHz chip
- MicroSD compatibility
- Fingerprint sensor
- A 3,300 mAh battery to power it all
