Ricoh CX3 vs Sony RX10 IV: A Hands-On Comparative Review for Discerning Photographers

When it comes to superzoom cameras, the market spans a vast spectrum - from lightweight, pocket-friendly compacts to hefty bridge cameras that verge on DSLRs in capability. Today, I’ve got two fascinating contenders on my test bench: the Ricoh CX3, a veteran compact superzoom launched in 2010, and the Sony RX10 IV, a state-of-the-art bridge camera unveiled in 2017. Though both claim the superzoom mantle, their designs, specs, and ultimately user experiences couldn’t be more different.

After extensive side-by-side testing covering everything from sensor technology and autofocus to real-world shooting across genres, I’m here to provide you with an exhaustive comparison. Whether you’re a casual snapshooter or a pro weighing a compact secondary camera, this article will help you navigate the key differences and decide which model fits your needs, lifestyle, and creative ambitions.

First Impressions: Size, Ergonomics, and Build Quality

Before the pixels and specs, I always pay attention to physical handling and comfort - because the best camera is the one you actually want to carry and use day after day.

The Ricoh CX3 is a featherweight at just 206 grams, housed in a compact body measuring 102x58x29 mm. It slips easily into a coat pocket or purse - ideal for the photographer who prioritizes portability and an unintrusive profile. Its fixed lens allows a fully sealed, minimalistic design (though note there is no mention of environmental sealing, so expect caution in harsh conditions).

Contrast that with the RX10 IV, which weighs a robust 1095 grams - more than five times heavier - and measures 133x94x145 mm, a true “bridge” camera built like a mini DSLR. The Sony sports a tough, weather-sealed body, designed for professional or adventure use where dust, moisture, or temperature extremes could prevail.

Clearly, these two cameras target vastly different ergonomic expectations. The CX3’s compact simplicity suits street photography or casual travel, while the RX10 IV’s bulk and rugged construction appeal to dedicated photographers who need a reliable workhorse.

Control Layout and User Interface

Handling isn’t just size - control layout and tactile feedback are equally crucial, especially for photographers who want rapid manual adjustments.

The CX3 features a restrained control scheme befitting its entry-level compact class - there are no dedicated dials for aperture or shutter priority, and no customizable buttons. This means the interface relies heavily on menus, which can interrupt shooting flow. The rear features a fixed 3-inch LCD without any touch functionality.

By contrast, Sony’s RX10 IV offers a professional-grade interface with numerous customizable dials and buttons, including dedicated rings for zoom, focus, and aperture control. Its tilting 3-inch touchscreen LCD (with 1440-dot resolution) complements the high-resolution electronic viewfinder (100% coverage, 0.7x magnification). This setup facilitates quick composition in challenging light and versatile shooting angles.

If you’re a photographer who loves quick manual overrides, the RX10 IV’s ergonomics will feel intuitive and satisfying. The CX3 tends toward easier point-and-shoot use with manual focus only accessible through menu selection.

Sensor Technology: Core Imaging Differences

The heart of any camera is its sensor, and here the differences between these two cameras are profound. I ran standardized tests - shooting standardized charts and real-world scenes under controlled conditions - to evaluate resolution, dynamic range, noise performance, and color reproduction.

The Ricoh CX3 uses a 1/2.3-inch BSI-CMOS sensor with 10 MP resolution (3648x2736 pixels). While this sensor was competitive in its era, its size (6.17 x 4.55 mm) and pixel density limit dynamic range, low-light performance, and fine detail resolution. The maximum ISO tops out at 3200, with no RAW support - which means less latitude for post-processing. Color depth is typical of entry-level sensors: adequate but not impressive.

On the other hand, the Sony RX10 IV houses a substantially larger 1-inch BSI-CMOS sensor, measuring 13.2 x 8.8 mm (roughly four times the area of the CX3’s sensor) and packing 20 MP resolution at 5472 x 3648 pixels. This sensor's greater size yields superior light gathering ability, wider dynamic range, reduced noise at high ISO, and finer tonal gradations. It also supports 14-bit RAW capture, unlocking professional-grade editing flexibility.

Testing confirmed that the RX10 IV delivers cleaner images at ISO 6400 and above, with noticeably richer shadow recovery and punchier colors. Sharpness and resolving power are also significantly higher, particularly useful when cropping or printing large.

Display and Viewfinder

Shooting experience hinges on your ability to confidently frame and review images.

The Ricoh CX3’s fixed 3-inch LCD at 920k dots works adequately for composing and reviewing images outdoors in good light but lacks touch interaction or articulation - meaning awkward shooting angles can be challenging.

Sony’s RX10 IV wins hands down here with a tilting 3-inch touchscreen and a high-res electronic viewfinder (EVF) with 100% frame coverage, a rarity at this price point. The EVF is invaluable in bright sunlight or for action photography, and the touchscreen speeds manual focus selection and menu navigation. This combination makes shooting far more versatile and pleasant.

Autofocus System and Speed

Autofocus performance is decisive in many photography genres, particularly wildlife, sports, and street photography. I timed and evaluated focusing speed and accuracy under various conditions - static subjects, moving targets, low light.

The Ricoh CX3 uses a contrast-detection autofocus system with single AF mode only. It lacks face or eye detection, and does not track moving subjects. In practical terms, AF is slow, hunting can be distracting, and focus accuracy is hit-or-miss on moving subjects. Manual focus is possible but fiddly due to the control layout.

The Sony RX10 IV features a hybrid AF system, pairing 315 phase-detect AF points with contrast detection, enabling fast and precise focus lock. Eye AF for humans and animals is supported, and 24fps continuous shooting with AF tracking makes it a potent option for fast action or wildlife photography. The “AF Lock” capability combined with customizable AF area selection enhances compositional control during continuous shooting.

In real-world use, the RX10 IV’s AF never left me waiting - even in low-light indoor sports or quick street candids - while the CX3 struggled to maintain focus in anything beyond static daylight scenarios.

Lens Quality and Zoom Range: Versatility on Tap

Both cameras feature fixed, non-interchangeable superzoom lenses but their specifications differ sharply.

The Ricoh CX3 sports a 28-300 mm equivalent zoom with F3.5-5.6 maximum aperture. This 10.7x zoom covers a useful range for general photography and macro focusing down to 1 cm is impressive for close-ups. However, optical quality - especially at the telephoto end - shows softness and chromatic aberration, quite noticeable in prints.

The Sony RX10 IV packs a spectacular 24-600 mm equivalent lens with a bright maximum aperture range of F2.4-4.0 - allowing better low-light performance and shallower depth-of-field capabilities. Thanks to high build quality and advanced optics, sharpness remains consistent even at maximum zoom. The lens benefits from optical stabilization, which synergizes with in-body stabilization for razor-sharp photos handheld at long focal lengths.

The RX10 IV’s greater zoom reach and lens quality make it a more all-encompassing tool for wildlife, sports, landscape, and portrait photography.

Image Stabilization

Both cameras offer image stabilization, but the approach differs significantly.

Ricoh uses sensor-shift stabilization, which within this class of compacts can reduce moderate camera shake for slower shutter speeds. However, given the sensor's size and lens property, the effectiveness is limited beyond short telephoto or indoors.

Sony deploys an elaborate optical image stabilization system built into the lens matched with sensor-shift stabilization to maximize effectiveness. This dual mechanism provides steady images and smooth video capture, vital for telephoto and low-light handheld shooting.

Video Capabilities: From Casual Clips to Professional Content

If you shoot video, your needs will guide the choice between these cameras.

The Ricoh CX3 supports 720p HD video at 30fps saved in Motion JPEG format. It has no microphone or headphone ports and no in-camera stabilization dedicated to video. Resulting footage tends to be soft with limited dynamic range, suiting only casual use.

The Sony RX10 IV offers 4K UHD video at 30p in advanced codecs (MPEG4, AVCHD, XAVC S), alongside Full HD at 60p. It includes a microphone input and headphone jack for precise audio monitoring. Its lens stabilization helps generate smooth, professional-grade footage even at full zoom. Features like zebra patterning, focus peaking, and manual exposure modes make it a solid hybrid stills/video camera.

Battery Life and Storage

Battery longevity can be a deal-breaker for field photographers.

Ricoh CX3 uses the DB-100 battery, with unknown official CIPA rating, but in practice it tallies less than 200 shots per charge - a figure common for compacts of its era, requiring frequent USB or external charging.

The RX10 IV employs the NP-FW50 battery, CIPA-rated for around 400 shots per charge, which is respectable for a camera with such a large sensor and electronic viewfinder. Supporting USB charging is missing but the robust capacity suits long shoots better.

Both cameras use a single SD card slot, with Sony supporting SDXC and Memory Stick formats. The RX10 IV’s compatibility with higher capacity and faster cards supports large RAW and 4K files efficiently.

Connectivity and Extras

In the flood of wireless integration, the Ricoh CX3 has no wireless or Bluetooth features - no GPS, Wi-Fi, or NFC. This limits instant sharing or remote control capabilities.

The Sony RX10 IV includes built-in Wi-Fi with NFC and Bluetooth, compatible with the Sony Imaging Edge app for remote shooting, image transfer, and geotagging. The addition of a hot shoe lets you attach external flashes or accessories, expanding creative possibilities.
