Canon SX70 HS vs Ricoh PX: In-Depth Comparison for Serious Enthusiasts and Professionals

Choosing the right camera means more than chasing specs; it’s about matching tools to creative intent. Today, I’m diving deep into a comparative analysis of two small sensor cameras that epitomize different eras and approaches to portable imaging: the Canon PowerShot SX70 HS (announced 2018) and the Ricoh PX (announced 2011). While both cameras share the “small sensor” label, they diverge sharply in features, handling, and target use cases. I’ve run both through extensive field tests and lab measurements, and this article distills those insights to help you decide which suits your photography needs best.

Before unpacking their capabilities, here’s a quick look at how they stack up physically:

Handling & Ergonomics: Bridge vs. Compact – Feel the Difference

Canon SX70 HS adopts the classic bridge camera form factor – roughly SLR-like, comfortably contoured for two-handed shooting, and sporting an extensive array of tactile controls. Its body dimensions (127x91x117 mm) and heft (608g) give it a reassuring grip, alleviating fatigue during extended shoots. The rubberized thumb rest and logically placed dials, including a top mode dial and rear joystick, cater to photographers who prefer manual control and quick setting adjustments without diving into menus.

Contrastingly, the Ricoh PX is a compact gem designed for rapid point-and-shoot convenience. Measuring just 100x55x21 mm and weighing a featherlight 156g, it slips conveniently in a pocket or purse - ideal for casual photography or situations demanding discretion. The PX’s smaller 2.7-inch fixed screen, minimalist button layout, and absence of an electronic viewfinder reflect its no-nonsense compact DNA.

The Canon’s ergonomic superiority is evident for serious photography, especially with longer lenses, but the PX wins on portability. It’s a classic trade-off: comfort and control versus simplicity and pocketability.

Sensor and Image Quality: The Heart of the Matter

Both cameras share the 1/2.3-inch sensor size (6.17 x 4.55 mm), which suggests inherent limitations in noise performance and dynamic range compared to larger APS-C or full-frame sensors. However, the Canon SX70 HS sports a 20-megapixel backside-illuminated (BSI) CMOS sensor coupled with Canon’s Digic 8 image processor, a notable evolution over the PX’s 16-megapixel CCD sensor and Ricoh’s Smooth Imaging Engine IV processor.

BSI technology on the Canon is a significant leap. By flipping the sensor structure, it allows more light to reach the photodiodes, resulting in better low-light sensitivity and noise control. I observed cleaner images from the SX70 HS at ISO 800 and above - a crucial advantage for indoor, wildlife, or night shooting.

Additionally, the Canon supports RAW capture, giving creative pros full control over post-processing, while the Ricoh PX lacks RAW mode, restricting you to JPEGs - a serious drawback for professionals or enthusiasts wanting ultimate image manipulation freedom.

Here’s a side-by-side comparison of sensor specs that frame this difference:

Real-world image quality differences become more pronounced in challenging conditions. The PX’s older CCD struggles with noise and dynamic range, resulting in muted shadows and highlights that clip more easily. In daylight or well-lit scenes, it still delivers respectable sharpness, but don’t expect subtle gradations or punchy colors out of it.

Screen and Viewfinder: Framing Your Shot

The SX70 HS has a 3-inch fully articulated LCD panel with 922k-dot resolution and an electronic viewfinder (EVF) delivering 2.36 million dots and 100% coverage. This bright, crisp EVF is indispensable when shooting in strong sunlight, allowing precise composition and focus confirmation. The articulating screen adds versatility, great for high/low-angle shots, video, or selfies (the SX70 supports selfie mode).

In contrast, the PX provides a modest, fixed 2.7-inch LCD with only 230k-dot resolution and omits any viewfinder, forcing you to compose solely on the rear screen. This limitation becomes challenging in bright daylight or for photographers who prefer eye-level framing.

The quality and flexibility of the Canon’s interface dramatically enhance shooting comfort and precision. For prolonged use or diverse shooting scenarios, I found the SX70 HS’s EVF and articulating screen a game changer. The PX’s approach suffices for casual snaps but frustrates when detailed framing or quick composition changes are needed.

Autofocus and Speed: Nailing the Moment

Autofocus (AF) is a standout differentiator. The SX70 HS features a contrast-detection AF system with 9 focus points, including face detection capability and continuous AF during burst shooting. Although it lacks phase-detection AF, the camera manages surprisingly fast and accurate focusing, even under dynamic conditions - such as tracking moving subjects in sports or wildlife photography.

The Ricoh PX employs a contrast-detection system as well but is severely limited to single AF mode only, without continuous AF during bursts. Its focusing speed is moderate and occasionally hesitant in low contrast or dimly-lit situations. The absence of multi-point AF or face detection further underscores the PX’s entry-level positioning.

In practical terms, the Canon SX70 HS’s continuous 10 frames per second burst with AF tracking lets you capture fleeting moments with much higher keeper rates. The PX shoots at a mere 1 fps and effectively requires you to pre-focus, limiting its use for motion-heavy genres.

Zoom & Lens Versatility: Superzoom vs. Moderate Reach

The Canon SX70 HS boasts a phenomenal 65x optical zoom with a focal length range of 21-1365mm (35mm equivalent) and maximum aperture of f/3.4–6.5. While the max aperture narrows towards the telephoto end, having an ultra-long lens integrated is invaluable for wildlife, sports, and even certain landscape or travel photography scenarios where versatility is paramount.

The Ricoh PX offers a more modest 5x zoom, from 28-140mm (35mm equivalent), with a maximum aperture of f/3.9–5.4. This range suffices for everyday snapshots and moderate telephoto work but can’t rival the reach or framing flexibility of the SX70 HS.

Worth noting: the PX shines in its macro performance with a 3cm close focusing capability versus the Canon’s 0cm (though practical macro usefulness of a bridge zoom is limited). The PX’s sensor-shift image stabilization provides steadier handheld macro shots despite the shorter zoom.

Build Quality and Durability: Taking the Hit or Braving the Weather

The Ricoh PX is described as environmentally sealed, meaning it resists dust and dampness - a smart feature for outdoor enthusiasts who want ruggedness in a small package. However, it is not waterproof or shockproof.

The Canon SX70 HS does not offer specific weather sealing, though it’s built robustly with high-quality plastics and metal reinforcements but should be treated with care in harsh environments.

For adventure and travel photographers prone to adverse conditions, the PX’s sealed design offers peace of mind at the cost of fewer manual controls and modest imaging specs.

Battery Life & Storage Capabilities: Ready for a Marathon or Quick Snaps?

Canon rates the SX70 HS’s battery life at approximately 325 shots per charge using its dedicated rechargeable lithium-ion battery. This is respectable for a bridge camera with a large EVF and extensive electronics. Given the power draw of its 65x zoom lens and live view EVF, carrying spares is advisable for heavy use.

The Ricoh PX uses a DB-100 battery with unspecified shot life, but given its compact form and older tech, real-world usage suggests shorter endurance than the Canon. This camera is better suited to shoot-and-go bursts rather than long sessions.

Both cameras use SD cards, with SDHC/SDXC and UHS-I support on the Canon - important for faster write speeds, especially when recording 4K video.

Video Capabilities: Full 4K vs. Basic HD

A big gap appears in video features: the Canon SX70 HS supports 4K UHD recording at 30p, encoding with efficient H.264 and AAC, capturing crisp footage with notable stabilization.

The Ricoh PX maxes out at 720p HD recording, stored in Motion JPEG format - a dated codec producing larger files with less color depth and detail.

For videographers needing smooth, high-resolution video, the SX70 HS is the clear winner. Its microphone input also enables higher audio quality, unlike the PX’s lack of dedicated audio ports.

Wireless Connectivity & Extras: Modern Convenience vs. Simplicity

The Canon SX70 HS has built-in Wi-Fi and Bluetooth, facilitating seamless image transfer, remote shooting, and tethered control with Canon’s smartphone apps. The PX offers no wireless connectivity, reflecting its older design.

This makes a big difference in workflow speed, especially for travelers or pros who want instant sharing or backup.

Pricing & Value: What Are You Getting for Your Dollar?

At launch and currently, the Canon SX70 HS retails around $550, while the Ricoh PX hovers near $330 secondhand given its age and limited capability.

For the extra investment, the Canon delivers vastly more in speed, reach, image quality, and flexibility. The Ricoh’s niche is compact ruggedness and simplicity, but at the cost of dated features and modest image results.

How These Cameras Perform Across Photography Genres

Let’s take a closer look at their practical suitability by genre, summarized here:

Portrait Photography

The Canon’s 20MP sensor and fast contrast-detect AF with face detection produce pleasant skin tones and eye-tracking for tack-sharp portraits. The long zoom can achieve impressive background blur at telephoto lengths despite the small sensor. The Ricoh PX falls short here: limited dynamic range and lack of RAW plus modest zoom make it less ideal for nuanced portraiture.

Landscape Photography

Here, resolution and dynamic range matter. Both share the same sensor size caps, but the Canon’s DIGIC 8 processor pulls more detail from shadows and highlights. Weather sealing tips toward Ricoh for tough conditions, but the SX70’s superb zoom means distant landscapes can be captured with stunning detail.

Wildlife & Sports Photography

Burst rate and AF tracking tell the tale. Canon’s 10fps continuous shooting with tracking blows the PX’s 1fps single shot out of the water. Its zoom is also vastly superior. PX’s slower AF precludes use in action-heavy scenarios.

Street Photography

The Ricoh PX’s smaller size and quieter operation offer discretion. However, the Canon’s EVF can aid framing in tricky light. The PX’s slower AF and lack of burst limit candids.

Macro Photography

Ricoh PX shines with its 3cm macro focusing and sensor-shift stabilization - more practical than a superzoom bridge lens for close-ups.

Night & Astro Photography

Canon’s BSI sensor and better noise control with RAW make it the clear choice for low-light and astro shooters.
