The Best Mobile Phone Cameras: A Comparison
For many, the camera is the most important feature of a mobile phone. Gone are the days of grainy, low-resolution images; modern smartphones boast impressive camera systems capable of capturing stunning photos and videos. But with so many options available, how do you choose the best one? This comparison will break down the key camera features and help you understand what to look for.
When considering a new phone, think about what Phones offers. While we don't sell phones directly, we can help you find the best deals and plans to suit your needs.
1. Megapixel Count and Sensor Size
Megapixel Myth
Megapixels (MP) are often the first specification people look at, but they don't tell the whole story. A higher megapixel count means the camera can capture more detail, allowing for larger prints and more aggressive cropping. However, a larger megapixel count on a small sensor can actually lead to worse image quality, especially in low light.
The key takeaway is that megapixels are only one piece of the puzzle. A 12MP camera with a large sensor can often outperform a 48MP camera with a smaller sensor.
Sensor Size: The Real Deal
The sensor is the heart of the camera. It's the component that actually captures the light and converts it into an image. A larger sensor can gather more light, resulting in brighter, clearer images with less noise, especially in challenging lighting conditions. Larger sensors also generally offer better dynamic range, meaning they can capture more detail in both the highlights and shadows.
Comparison:
iPhone 14 Pro: 48MP main camera with a larger sensor compared to previous iPhones.
Samsung Galaxy S23 Ultra: 200MP main camera with a large sensor, allowing for incredible detail and impressive zoom capabilities.
Google Pixel 7 Pro: 50MP main camera with a large sensor, known for its excellent image processing and dynamic range.
Pros of High Megapixel Count:
More detail in images
Greater cropping flexibility
Larger print sizes
Cons of High Megapixel Count:
Can lead to smaller pixel size and reduced low-light performance if the sensor size is not also increased.
Larger file sizes
2. Lens Aperture and Image Stabilisation
Aperture: Letting in the Light
The aperture is the opening in the lens that allows light to pass through to the sensor. It's measured in f-stops (e.g., f/1.8, f/2.2). A lower f-stop number indicates a wider aperture, which means the lens can let in more light. A wider aperture is beneficial in low-light situations, as it allows the camera to capture brighter images with less noise. It also creates a shallower depth of field, resulting in a blurred background (bokeh) that is often desirable for portrait photography.
Examples:
A phone with an f/1.5 aperture will perform better in low light than a phone with an f/2.2 aperture.
A wider aperture is ideal for portrait mode, creating a pleasing background blur.
Image Stabilisation: Keeping Things Steady
Image stabilisation (IS) helps to reduce blur caused by camera shake. There are two main types of image stabilisation:
Optical Image Stabilisation (OIS): This physically moves the lens or sensor to compensate for camera shake. OIS is generally more effective than EIS.
Electronic Image Stabilisation (EIS): This uses software to digitally stabilise the image. EIS can sometimes introduce artifacts or reduce image quality.
Why is Image Stabilisation Important?
Sharper photos, especially in low light or when using zoom.
Smoother video recording, reducing shaky footage.
Comparison:
Most high-end phones offer both OIS and EIS for optimal stabilisation.
Some mid-range phones may only offer EIS.
Check the specifications to see what type of stabilisation is offered.
3. Video Recording Capabilities
Modern smartphones are capable of recording incredibly high-quality video. Key features to consider include:
Resolution: 4K is now standard, but some phones can record in 8K.
Frame Rate: 30fps is standard, but 60fps or higher is ideal for capturing smooth action footage. Some phones offer even higher frame rates for slow-motion video.
Dynamic Range: Look for phones that support HDR (High Dynamic Range) video recording for better detail in highlights and shadows.
Stabilisation: Good image stabilisation is crucial for smooth video recording, especially when shooting handheld.
Audio Recording: The quality of the microphones is important for capturing clear audio. Some phones offer features like wind noise reduction.
Comparison:
iPhone: Known for its excellent video quality and cinematic mode, which allows you to adjust the depth of field after recording.
Samsung: Offers a wide range of video recording options, including 8K recording and advanced stabilisation features.
Google Pixel: Features excellent dynamic range and stabilisation, resulting in natural-looking video.
4. Low-Light Performance
Low-light performance is one of the most challenging aspects of mobile phone photography. Here's what contributes to good low-light performance:
Large Sensor: As mentioned earlier, a larger sensor can capture more light.
Wide Aperture: A wider aperture allows more light to reach the sensor.
Image Processing: Sophisticated image processing algorithms can reduce noise and brighten images in low light.
Night Mode: Many phones now offer a dedicated night mode that uses long exposure times and advanced processing to capture brighter, clearer images in very dark conditions.
How to Evaluate Low-Light Performance:
Look for reviews that specifically test low-light performance.
Compare sample images taken in low-light conditions.
Pay attention to the amount of noise and detail in the images.
Comparison:
Google Pixel phones are consistently praised for their exceptional low-light performance thanks to their computational photography prowess.
iPhone and Samsung phones also offer excellent low-light capabilities, with dedicated night modes that produce impressive results.

5. Special Camera Features: Portrait Mode, Night Mode
Portrait Mode: Achieving the Bokeh Effect
Portrait mode uses software to create a shallow depth of field, blurring the background and isolating the subject. This effect, known as bokeh, is often desirable for portrait photography. The quality of portrait mode depends on the accuracy of the depth mapping and the realism of the background blur.
Key Considerations for Portrait Mode:
Edge Detection: How accurately does the phone separate the subject from the background?
Bokeh Quality: How natural and pleasing is the background blur?
Adjustability: Can you adjust the amount of blur after taking the photo?
Night Mode: Illuminating the Darkness
Night mode uses long exposure times and advanced image processing to capture brighter, clearer images in very dark conditions. The phone typically takes multiple exposures and combines them to reduce noise and increase detail. Night mode can be incredibly effective, but it requires the phone to be held steady or placed on a tripod.
Key Considerations for Night Mode:
Brightness: How much brighter does the image become?
Noise Reduction: How effectively does the phone reduce noise?
Detail: How much detail is preserved in the image?
Processing Time: How long does it take to process the image?
Comparison:
Google Pixel's Night Sight is widely regarded as one of the best night modes available, producing incredibly bright and detailed images in near-total darkness.
iPhone's Night Mode is also excellent, offering a natural-looking balance between brightness and detail.
Samsung's Night Mode is constantly improving, offering impressive results in a variety of low-light scenarios.
