Samsung Galaxy A9 (2018): A Deep Dive into its Quad-Camera System
Samsung a9 4 camera specification – The Samsung Galaxy A9 (2018) made waves with its groundbreaking quad-camera setup, a first for Samsung at the time. This article provides a comprehensive analysis of its camera specifications, features, image quality, user experience, and a comparative analysis against competitors. We’ll delve into the details of each sensor, exploring its strengths and weaknesses to provide a complete picture of this innovative camera system.
Camera Sensor Details

The Samsung Galaxy A9 boasted four distinct rear cameras, each designed to excel in specific photographic scenarios. The following table details the specifications of each sensor.
| Camera | Megapixel Count | Sensor Size (Approximate) | Pixel Size (Approximate) |
|---|---|---|---|
| Main Camera | 24MP | 1/2.5″ | 0.9µm |
| Telephoto Camera | 10MP | 1/3.4″ | 1.22µm |
| Ultra-Wide Camera | 8MP | 1/4″ | 1.12µm |
| Depth Sensor | 5MP | N/A | N/A |
The 24MP main sensor provided excellent detail and dynamic range in well-lit conditions. The 10MP telephoto lens offered 2x optical zoom, useful for capturing distant subjects. The 8MP ultra-wide lens expanded the creative possibilities with its wider field of view. The 5MP depth sensor aided in portrait mode, producing a pleasing bokeh effect. Low-light performance varied; the main sensor generally performed well, while the other sensors struggled in very low light due to their smaller sensor sizes and pixel counts.
Color accuracy was generally good across all sensors.
Camera Aperture Comparison

Aperture size significantly impacts depth of field and low-light performance. A larger aperture (smaller f-number) allows more light to hit the sensor, resulting in brighter images and a shallower depth of field (blurred background). The following table compares the aperture sizes of the A9’s cameras.
| Camera | Aperture | Depth of Field Implications | Low-Light Implications |
|---|---|---|---|
| Main Camera | f/1.7 | Shorter depth of field, good for portraits | Better low-light performance |
| Telephoto Camera | f/2.4 | Deeper depth of field | Lower light sensitivity |
| Ultra-Wide Camera | f/2.4 | Deeper depth of field | Lower light sensitivity |
| Depth Sensor | f/2.2 | Used for depth sensing, not image capture | Not applicable |
Camera Features and Functionality
Beyond the sensor specifications, several software and hardware features enhanced the A9’s camera capabilities.
- Main Camera: PDAF autofocus, EIS (Electronic Image Stabilization), 4K video recording at 30fps, 1080p at 60fps.
- Telephoto Camera: PDAF autofocus, OIS (Optical Image Stabilization), 1080p video recording at 30fps.
- Ultra-Wide Camera: Fixed focus, EIS, 1080p video recording at 30fps.
- Depth Sensor: Used for depth mapping in Live Focus mode.
Software features included scene optimizer, pro mode (manual control over ISO, shutter speed, white balance, and exposure), and various post-processing options within the gallery app. The optical zoom offered by the telephoto lens provided decent quality up to 2x, while digital zoom resulted in noticeable image degradation beyond that range.
Image and Video Quality Assessment, Samsung a9 4 camera specification
Image quality varied depending on the camera and lighting conditions.
| Camera | Daylight | Low Light | Indoor |
|---|---|---|---|
| Main Camera | Excellent detail, good dynamic range | Good detail, some noise | Good detail, acceptable noise |
| Telephoto Camera | Good detail, slightly less dynamic range than main camera | Noticeable noise | Moderate noise |
| Ultra-Wide Camera | Acceptable detail, some distortion at edges | Significant noise | High noise levels |
| Depth Sensor | Not applicable | Not applicable | Not applicable |
Video quality was generally good, with the main camera offering the best stabilization and dynamic range. The 4K video recording mode produced high-resolution footage, although stabilization was less effective at this resolution compared to 1080p.
Camera App Interface and User Experience
The camera app interface was intuitive and easy to navigate. Switching between cameras was straightforward, and accessing various shooting modes and settings was simple. Focusing was generally quick and accurate.
- Pros: Easy-to-use interface, quick access to various modes, good responsiveness.
- Cons: Some users reported occasional lag in switching between cameras, and the pro mode could be improved with more granular control.
Comparative Analysis with Competitors
Comparing the Samsung Galaxy A9 (2018) to its contemporaries reveals its strengths and weaknesses within the market landscape. Here’s a comparison with three competing models (specifications are approximate and may vary based on the specific model and region):
| Feature | Samsung Galaxy A9 (2018) | Huawei P20 Pro | Google Pixel 3 | iPhone XS Max |
|---|---|---|---|---|
| Main Camera MP | 24MP | 40MP | 12MP | 12MP |
| Telephoto Camera MP | 10MP | 8MP | 12MP | 12MP |
| Ultra-Wide Camera MP | 8MP | – | – | – |
| Video Recording (Max) | 4K@30fps | 4K@60fps | 4K@30fps | 4K@60fps |
While the A9’s quad-camera setup was innovative, competitors like the Huawei P20 Pro and Google Pixel 3 offered superior image processing and computational photography capabilities, resulting in better low-light performance and overall image quality in some cases, despite having fewer cameras. The iPhone XS Max, while lacking an ultra-wide lens, offered excellent image quality and video capabilities. The A9 provided a good balance of features at a competitive price point, especially considering its innovative quad-camera setup.
