Canon SX30 IS vs Sony RX10

Two Bridge Cameras, Two Eras, One Choice: Canon SX30 IS vs Sony RX10 Unveiled

Having spent over 15 years testing countless digital cameras, I find revisiting bridge cameras - those curious hybrids between compact point-and-shoots and DSLRs - always illuminates how technological leaps shape photographic experience. Today, I share my firsthand insights on two iconic “bridge superzoom” cameras from distinct periods and design philosophies: Canon’s PowerShot SX30 IS (from 2010) and Sony’s Cyber-shot DSC-RX10 (from 2014). Both share an SLR-like body style and a versatile zoom, yet their core technologies and performance stand worlds apart.

Whether you prioritize reach, image quality, speed, or ruggedness, join me as we dig into their build, optics, sensors, and more to see which camera holds up for today’s enthusiast or pro seeking a reliable all-in-one solution.

Hands-On First Impressions: Size, Shape & Controls

Right from lifting these cameras, it’s clear the RX10 is designed to feel more robust and substantial. Weighing in at 813g versus the SX30 IS’s lighter 601g, Sony has packed a bigger sensor and better build into a similarly sized body. The dimensions are surprisingly close, though the SX30 is a touch chunkier at 123x92x108mm compared to RX10’s 129x88x102mm.

Handling these cameras, I appreciate the classic bridge form factor - grippy contours, protruding grips, and DSLR-style control layouts. The RX10 offers a more refined finish with a metal chassis and weather sealing - features absent on the plasticky SX30. The Canon feels more like a transitional device between a compact and an SLR, while the Sony confidently leans into pro territory.

The top views clearly spotlight the RX10’s superior dials and button placements for direct access to ISO, exposure compensation, and shooting modes, lending greater intuitive control when shooting fast-paced scenes.

For the enthusiast stepping up from compact cameras or DSLRs seeking something lighter and easier, the SX30 IS is approachable. But professionals and serious hobbyists will find RX10’s build and control sophistication more satisfying during extended shoots or in challenging conditions.

Sensor & Image Quality: The Heart of the Matter

This is where the greatest gulf lies - sensor size and associated image quality. The SX30 relies on a small 1/2.3-inch CCD sensor measuring just 6.17x4.55mm, producing 14 megapixels. In stark contrast, the RX10 boasts a much larger 1-inch BSI-CMOS sensor (13.2x8.8mm) with 20 MP resolution.

Why does sensor size matter? Larger sensors gather more light, yield lower noise, and offer greater dynamic range - critical for realistic landscapes, clean low-light portraits, and astrophotography. Sony’s BSI (Backside-Illuminated) CMOS design further increases sensitivity and reduces noise compared to traditional CCD found in Canon’s SX30 IS.

In my lab tests and field shooting, the RX10 confidently delivers cleaner images at ISO 800 and beyond, retaining rich colors and fine detail. Conversely, the SX30 starts showing grain and color shifts past ISO 400, limiting its low-light usability.

Dynamic range, another crucial factor for highlights and shadows recovery, is measured at 12.6 EV for the RX10 versus an untested but characteristically lower range for the SX30’s older sensor. When shooting bright clouds or deep shadows in landscapes, Sony’s sensor consistently produced more nuanced files.

Canon’s SX30, although dated, still renders pleasing 14MP JPGs in good light situations. Skin tones in portraits are warmer and flattering, partly thanks to Canon’s well-tuned DIGIC 4 processor. However, expect to struggle with noise and flattening colors as the ISO climbs.

Display & Viewfinder: Framing Your Shot

The LCD screen and electronic viewfinder (EVF) provide the immediate interface between you and the scene. Here, Sony’s RX10 again advances the experience with a 3-inch tilting screen boasting 1.29 million dots employing a “WhiteMagic” tech for superior daylight brightness and clarity.

Canon’s SX30 lags with a smaller 2.7-inch articulated LCD and just 230k dots resolution - an older, dimmer panel that is harder to evaluate critical focus or exposure outdoors.

The RX10’s EVF matches its pro aspirations: a crisp 1.44 million dots viewfinder with 100% coverage and 0.7x magnification, offering fatigue-free framing and manual focus precision. SX30’s EVF resolution is unspecified and lower grade, feeling more like a convenience than a serious tool.

For video shooters or street photographers, RX10’s screen brightness and flexibility improve usability in imperfect lighting. Users who prioritize articulating screens for selfies or awkward angles might appreciate the Canon’s fully articulated display, which the RX10’s tilting screen cannot match.

Optics & Zoom Capability: Reach Versus Quality

The hallmark of these cameras is their superzoom lenses, stretching focal lengths for ultimate versatility. The SX30 offers an astounding 35x zoom spanning 24-840mm equivalent, while the RX10 sports a shorter but faster 8.3x zoom at 24-200mm.

Canon’s 35x reach is unmatched and extremely compelling for travelers and wildlife enthusiasts needing extreme telephoto reach with one lens. However, its variable aperture of f/2.7-5.8, combined with the small sensor, compromises image quality at longer focal lengths - sharpness drops and noise rises noticeably.

Sony’s RX10 lens is a constant f/2.8 across the zoom, an impressive feat that keeps exposure steady and depth of field control consistent. Optically, the RX10’s Zeiss-branded lens delivers superior sharpness edge-to-edge and improved control over chromatic aberration.

For detailed macro shots, the RX10 provides better close focusing abilities with nuanced focus precision aided by contrast-detection AF; the SX30's macro focus is “0 cm” meaning it can get pretty close but with less sophistication in focusing accuracy.

So the Canon zoom excels in range but compromises sharpness and low-light performance at telephoto; the Sony offers superior optical quality and aperture, though with less reach.

Autofocus Speed & Accuracy: Never Miss the Moment

Autofocus tech has evolved significantly, and the two cameras highlight this progress. The SX30 uses a contrast-detection system with nine AF points but no face detection or tracking capabilities. AF speed is slow, and continuous AF is absent, which I found frustrating for moving subjects.

The RX10 introduces a more advanced contrast-detection AF system with 25 points, face detection, and advanced selective AF modes. It supports continuous AF for burst shooting and live preview with great accuracy.

During wildlife outings and sports tests, the RX10 locked focus much more reliably on fast-moving targets, even in uneven light. SX30 struggled to maintain focus, often hunt-and-pecking, making it unsuitable for action photography.

Burst Rates & Video Performance: Capturing Motion

When shooting sports or wildlife, the ability to capture rapid bursts matters. The SX30’s continuous shooting maxes out at a sluggish 1 frame per second, far from practical for any movement-intensive photography.

The RX10 crushes this with a 10 fps burst mode, allowing photographers to seize the perfect split-second moment. This alone makes the RX10 a far more versatile action camera.

Video capabilities are another area where the RX10 pulls ahead. Canon caps video at 720p and 30 fps in Motion JPEG format, an antiquated format resulting in large files with moderate compression.

The RX10 records full HD 1080p video up to 60 fps with AVCHD and MPEG-4 codecs, providing far better quality and editing flexibility. It also includes external microphone and headphone jacks, important for serious video shooters wanting full audio control.

Build, Durability & Weather Sealing

For those shooting in the field, build quality and durability can be deciding factors. Sony’s RX10 features environmental sealing against light rain and dust, a metal chassis, and toughened lens elements, making it a rugged companion for travel and outdoor photography.

Canon’s SX30 IS lacks weather sealing and uses more plastic parts, making it lighter but less durable under demanding conditions. It’s best suited for casual trip photography rather than professional outdoor use.

Battery Life & Storage

RX10’s NP-FW50 battery delivers approximately 420 shots per charge, tested under moderate use, while Canon’s NB-7L battery specs aren’t clearly published but usage experience shows it requires more frequent recharging.

Both cameras accept SD cards, with the RX10 adding Sony’s proprietary Memory Stick compatibility. For extended outings, the RX10 offers more reliable stamina and better power management.

Connectivity: Keeping Up With the Times

Notably, the RX10 stands out with built-in Wi-Fi and NFC for fast wireless image transfer and remote control, features absent in the SX30 IS, which only supports Eye-Fi SD card connectivity - an older solution requiring specific cards.

Both cameras offer HDMI and USB 2.0 ports, but the RX10’s advanced wireless options are significant for social media savvy photographers and modern workflows.

Price & Value Analysis

At launch, the SX30 aimed at an entry-level bridge buyer with a $399 MSRP, while the RX10 priced at $698 targeted enthusiasts willing to invest for superior image quality and durability.

Today, given used market values and depreciation, the SX30 remains affordable but clearly outmatched. The RX10’s superior sensor, optics, AF, and video features justify its higher price for serious users.
