Ricoh CX3 vs Sony A9 II

Ricoh CX3 vs Sony A9 II: A Deep Dive into the Real-World Performance of Two Very Different Cameras

Choosing a camera can feel like an overwhelming decision, especially when comparing two models that sit at such opposite ends of the photography spectrum. Today, I’m putting the Ricoh CX3, a humble small-sensor superzoom compact from 2010, head-to-head with the Sony A9 II, a pro-grade full-frame mirrorless flagship from 2019. Yes, it’s a bit like comparing a bicycle to a motorcycle, but beyond the obvious, you’ll find some interesting contrasts that highlight what camera technology can offer across the board. Whether you’re new to photography or a seasoned pro, this thorough comparison will help clarify which camera fits your shooting style, needs, and budget.

Let’s start by seeing the physical contrast between these two:

Two Worlds Apart: Body Type and Build

Right off the bat, the Ricoh CX3 is a compact little pocket cruiser weighing a mere 206 grams, designed to slip easily into your jacket pocket or purse. Its small size and simple fixed lens with 10.7x zoom make it approachable for casual shooters who value ease of use and portability. The body measures 102x58x29mm - a truly compact package.

On the flip side, the Sony A9 II is a robust, SLR-style mirrorless body, weighing 678 grams and measuring 129x96x76mm. It feels substantial in hand, built with pro use in mind with a magnesium alloy chassis and weather sealing (although not fully waterproof or dustproof). If you shoot professionally or demand high reliability in tough environments, this camera’s build quality inspires confidence.

Ergonomics-wise, the Ricoh’s design leans minimalist with no electronic viewfinder or extensive physical controls, offering a fixed 3-inch screen with modest resolution. Meanwhile, the Sony boasts a top-tier ergonomic layout with multiple customizable buttons, dual card slots, a large grip, and a wealth of dials and wheels - more than you’ll ever need for quick access to settings in a fast shoot.

Here’s a detailed look at how the control layouts differ:

That compact simplicity of the CX3 is great for casual snapshots. But once you want manual control, fast adjustments, and advanced focus modes, the Sony’s top deck reveals itself as an indispensable asset.

Sensor Size - The Heart of Image Quality

When it comes to image quality, the sensor size plays a fundamental role. The Ricoh CX3 uses a 1/2.3” BSI-CMOS sensor with a diagonal of around 6.5mm and 10 megapixels of resolution (3648 x 2736 pixels). This sensor is tiny compared to the Sony A9 II’s full-frame 24MP BSI-CMOS sensor measuring 35.6mm x 23.8mm.

Why does this matter? Larger sensors collect more light, resulting in better dynamic range, cleaner high-ISO performance, superior color depth, and overall sharper images. The Sony’s sensor area is roughly 30 times the size of the Ricoh’s!

In practice, this means the Ricoh will struggle in low light, producing noisier images with less detail. Highlight retention and shadow detail are limited. The 10MP resolution is modest by today’s standards but adequate for small prints and web sharing.

The Sony A9 II offers impressively wide dynamic range, vibrant but accurate color rendering, and native ISO from 100 to 51200, expandable up to 204800. This makes it highly versatile for everything from bright sunlit landscapes to dim indoor events or astrophotography.

LCD and Viewfinder: Seeing Your Shot

The Ricoh CX3 features a fixed 3-inch LCD screen with 920,000 dots. While it's bright enough for casual framing, the lack of articulating or touch functionality can be limiting, especially when shooting at odd angles or in bright daylight.

The Sony A9 II, however, tacks on a 3-inch tilting touchscreen LCD with a crisper 1.44 million dots resolution, making live view focusing and menu navigation far more intuitive.

Beyond that, the Ricoh lacks any form of viewfinder, electronic or optical, forcing you to rely entirely on the LCD. The Sony takes a commanding lead here with a high-resolution electronic viewfinder (EVF) boasting 3.686 million dots, 100% coverage, and a magnification of 0.78x, delivering a bright, detailed preview that approximates the final exposure.

For enthusiasts and pros alike, having a quality EVF is practically essential, especially in bright conditions where LCDs struggle.

Autofocus Systems – Speed, Accuracy, and Versatility

I’ve tested thousands of cameras, and autofocus remains a critical factor that often defines a camera’s suitability for certain genres. The Ricoh CX3 relies solely on contrast-detection autofocus with a single AF mode and no face or eye detection. It also lacks continuous AF and tracking, so capturing fast-moving subjects results in frequent focus hunting and missed shots.

By comparison, the Sony A9 II sports a state-of-the-art hybrid AF system with 693 phase detection points covering a wide area, paired with contrast detection for precision. It includes advanced features like animal eye AF, human eye AF, face detection, real-time tracking, and continuous autofocus. This system can lock focus almost instantly, maintain that lock with uncanny accuracy, and track rapid and erratic subjects effortlessly.

Whether you’re shooting wildlife with unpredictable movement, sports scrambling across the field, or street moments that flash by, the Sony delivers unmatched performance.

Lens and Zoom – Fixed Versus Interchangeable

One of the most fundamental differences of these cameras is the lens design. The Ricoh CX3 comes with a fixed zoom lens from 28mm to 300mm equivalent, f/3.5 to f/5.6. This long zoom range is a convenience for general photography without the hassle of changing lenses.

The Sony A9 II, however, uses Sony’s E-mount system compatible with over 120 native lenses ranging from ultra-wide primes to super-telephoto zooms, macro lenses, tilt-shifts, and specialty optics. This extensive ecosystem gives you the freedom to curate exactly the tools you need.

The optical quality of Sony’s premium lenses when paired with the high-resolution sensor ensures razor-sharp images with creamy bokeh not achievable on fixed-lens compacts. For professional work or serious enthusiasts, this flexibility is a decisive advantage.

Burst Shooting and Shutter Speeds

For those who like to freeze motion, the Sony A9 II’s silent electronic shutter mode supports shutter speeds up to an eye-watering 1/32000 second, while the mechanical shutter can reach 1/8000 second. It can shoot continuous bursts at up to 20 frames per second with AF/AE tracking. This is ideal for capturing flying birds, fast athletes, or fleeting expressions.

The Ricoh CX3 offers modest shutter speeds ranging from 8 seconds to 1/2000 second but lacks continuous shooting specs entirely. It simply “can’t keep up” with action, relegating it to static subjects.

Image Stabilization

One highlight of the Ricoh CX3 is its sensor-shift image stabilization, which helps reduce blur from hand shake, especially useful at long zoom telephoto ranges and in low light.

The Sony A9 II features a 5-axis sensor-based stabilization system that can effectively counteract pitch, yaw, roll, and shift movements. Coupled with stabilized lenses, this makes handheld shooting at slower shutter speeds achievable without blur, and greatly aids video stability.

Video Capabilities

Ricoh CX3 offers 720p HD video at 30fps using motion JPEG format. It’s basic but serviceable for casual video recording.

The Sony A9 II, designed for serious hybrid shooters, records 4K UHD video at 30fps with clean 8-bit color 4:2:0 internally and 4:2:2 with external recorder. It supports S-Log3 gamma profiles for professional color grading, plus has dedicated microphone and headphone jacks for sound monitoring.

The Sony’s video autofocus is smooth, silent, and tracks subjects seamlessly, a real advantage if you intend to shoot interviews, events, or documentaries.

Battery Life and Storage

The Ricoh CX3 uses a DB-100 battery. While exact battery life figures are unavailable, small compact cameras typically deliver around 200 shots per charge. Storage is via a single SD/SDHC card slot or internal memory.

Sony’s A9 II takes the much larger NP-FZ100 battery pack, providing approximately 690 shots per charge - a vital asset for long professional assignments or travel shoots. It has dual UHS-II SD card slots, ideal for backup, overflow, or separating RAW and JPEG files.

Connectivity and Extras

Connectivity is another stark contrast: the Ricoh CX3 has no wireless capabilities, no HDMI or microphone ports, and only USB 2.0.

Meanwhile, the Sony A9 II includes Wi-Fi, Bluetooth, NFC for streamlined image transfer and remote control, a full-size HDMI output, USB 3.1 Gen 1 port, microphone and headphone jacks, plus comprehensive flash sync and external flash compatibility. These features make it future-proof and workflow-friendly.
