Canon SX620 HS vs. Ricoh GR Digital III: A Hands-On Expert’s Take on Two Unique Compacts

Choosing the right compact camera often boils down to understanding trade-offs - in usability, image quality, and versatility. Today, I dive deep into two distinctly different yet intriguing models: the Canon PowerShot SX620 HS and the Ricoh GR Digital III. Both are pocketable and appealing to photography buffs but come from totally different philosophies.

Having rigorously tested hundreds of cameras across varied genres, I'll break down these two compacts with practical nuance, allowing you to weigh their capabilities honestly. Whether your next camera is destined for family trips, street photography sessions, or occasional macro fun, I’ll highlight which is the better fit.

Let’s jump in!

Physical Design and Handling: Comfort for Days or Pocketable Precision?

First impressions matter - especially in pocket-friendly cameras where ergonomics can make or break the shooting experience.

The Canon SX620 HS is a classic small superzoom compact. Measuring about 97 x 57 x 28 mm and weighing 182g, it fits nicely in most jacket pockets or larger shirt pockets. Its rounded edges and slight grip area mean you can hold it steadily without clutching clubs for thumbs.

In contrast, the Ricoh GR Digital III is a minimalist’s dream, with a boxier profile at 109 x 59 x 26 mm and a slightly heavier 208g. This extra heft, coupled with Ricoh’s hallmark flush button layout, offers excellent balance for street shooters seeking discretion. Its lack of a protruding grip encourages using your camera close to the body - a plus for blending in.

Both models forego electronic viewfinders - Canon offering none, Ricoh with an optional optical viewfinder accessory - to keep size down. The SX620’s fixed 3” rear LCD has 922K dots, and so does the GR Digital III’s 3” screen with 920K dots, both good enough for framing and reviewing shots yet no touchscreens here.

Control-wise, Canon’s SX620 HS keeps things simple with no clubs for thumbs - buttons and dials are sparse but logical. Ricoh’s GR Digital III, however, is all about photographers who want manual control at their fingertips, featuring dedicated exposure mode dials and direct access buttons, catering to purists ready to tinker with shutter and aperture.

Ergonomics winner? If you crave quick point-and-shoot with zoom, Canon. For manual lovers who prioritize control and pocketability, Ricoh wins.

Sensor Technology and Image Quality: Pixels, Noise, and Detail

Here’s where these pilots of small sensor cameras fundamentally diverge.

The Canon SX620 HS houses a 1/2.3" BSI-CMOS sensor with 20 megapixels - typical for its class but pushing resolution on such a small chip can sometimes invite noise, especially beyond ISO 800. Canon's DIGIC 4+ processor manages decent color reproduction but doesn’t have the muscle of newer chips. The huge 25x zoom means a smaller sensor area per pixel compared to wider lenses, which can impact sharpness at telephoto.

Meanwhile, the Ricoh GR Digital III sports a larger 1/1.7" CCD sensor with a solid 10 megapixels. Although fewer pixels, bigger sensor size means less noise and cleaner images, especially in good lighting. Ricoh’s CCD sensor, while aging tech compared to CMOS, does deliver punchy color and excellent detail retention - at least up to ISO 400, beyond which noise grows rapidly (typical for CCDs).

Interestingly, Ricoh supports RAW shooting, a bonus for enthusiasts wanting full post-processing freedom. Canon SX620 HS does not offer RAW but saves images in finely processed JPEGs geared toward social sharing.

From my experience running side-by-side ISO noise tests and dynamic range evaluations, Ricoh edges Canon in:

• Cleaner tones and highlight retention at ISO 100-400
• More natural gradation due to less aggressive noise reduction
• Sharper rendering thanks to its fast, wide F1.9 lens and larger sensor

Canon’s strength is versatility, allowing you to zoom from 25mm wide to a staggering 625mm telephoto, though you trade some optical clarity at the extremes.

Autofocus and Shooting Performance: Speed Dialing Your Moments

In real-world shooting, autofocus speed and accuracy can make or break fleeting moments.

The Canon SX620 HS offers contrast-detection autofocus with 9 focus points and supports face detection and tracking AF, plus continuous AF mode. Its focusing is generally reliable and picks up subjects quickly in good light, though struggles slightly in very dim scenes. Continuous shooting is modest at 2.5 fps - not suited for high-speed action but adequate for casual use.

The Ricoh GR Digital III features contrast-detection AF but with no continuous or tracking autofocus modes - only single AF. It excels at pinpoint accuracy but requires more deliberate compositional setups. Burst mode is absent, and shutter speeds max out at 1/2000 sec, meaning fast motion capture is limited.

For wildlife or sports hunting decisive bursts or rapid AF, Canon has a clear edge. For street photographers or macro shooters who work more contemplatively and value precision over speed, Ricoh’s straightforward AF suffices.

Lens and Zoom: Versatility vs. Pristine Primes

If zoom versatility is a priority (or fun factor), Canon is the boss here.

The SX620 HS lens covers a massive 25-625 mm range (equivalent), letting you nudge from wide landscapes to extreme telephoto wildlife snaps in one go. The aperture ranges from F3.2 (wide) to F6.6 (tele), which is a bit on the slower side when zoomed. Optical stabilization helps keep handheld shots sharp at long focal lengths.

The Ricoh GR Digital III sticks to a single fixed 28mm f/1.9 prime, famous in the compact world as a stellar street and everyday lens. That big aperture lets in lots of light for low-light shooting and creamy background separation - something zooms rarely accomplish. Its macro focusing comes down to an aggressive 1cm closest distance.

While the Ricoh’s lens lacks range, its sharpness and fast aperture make it a favorite with street, documentary, and environmental portrait shooters.

So, for travelers or casual users wanting one camera to do it all (zoom to infinity and beyond), Canon wins. For photographers who want the sharpest primes and work in available light, Ricoh is king.

Screen and Viewfinder: Seeing is Believing

Both cameras forego electronic viewfinders - understandable given their compact designs.

The SX620 HS’s 3” 922K dot screen is fixed (non-articulating) but bright and legible. The interface uses physical buttons without touchscreen support, meaning menu navigation feels traditional - fine once you know your way.

The Ricoh GR Digital III also offers a 3” 920K dot fixed LCD, with a simple, no-frills interface designed for quick access to critical settings, matching its manual photographic ethos.

Absent EVFs may bug some, especially in bright daylight, but both models compensate through solid screen visibility.

Build Quality and Weather Sealing: Taking a Beating

Neither camera offers weather sealing or ruggedization - it’s compact, not pro body rugged.

Both are built with plastic-heavy construction to keep weight down:

• Canon SX620 HS weighs 182g, smooth and light but feels less solid.
• Ricoh GR Digital III is 208g, a bit heavier and with a metal-like finish around the lens barrel giving a hint of durability.

Neither is shockproof, waterproof, or dustproof.

For rough outdoor trekking, both need care or protective cases.

Battery Life and Storage: Keep Shooting Longer

The Canon SX620 HS boasts a respectable 295 shots per charge, powered by battery pack cells typically lasting a full day of casual use. It uses SD/SDHC/SDXC cards, which are widely available and inexpensive.

Ricoh GR Digital III’s official battery life is unspecified but historically around 200-250 shots. It supports SD/SDHC cards plus internal storage for a handful of images - a useful backup if cards fill up.

Neither model supports USB charging, so carrying spares is wise.

Connectivity and Extras: Sharing Made Easy or Old School?

The Canon SX620 HS includes built-in Wi-Fi and NFC, letting you easily transfer images straight to smartphones or tablets - handy for social media sharing on the go. It also offers HDMI output for playback on TVs.

Ricoh is more old school: no wireless features, no HDMI output. You must remove the SD card or use USB 2.0 to offload images.

If instant sharing or remote control is important, Canon’s superior connectivity will be a decisive factor.

Video Capability: Modest Offerings Worth Considering

Neither model is a video powerhouse, but let’s compare.

• Canon SX620 HS: Full HD (1920 x 1080) video at 30 fps is solid for casual clips. Videos are encoded in MPEG-4 / H.264. Optical image stabilization aids smoother handheld footage. No microphone port or advanced video features.

• Ricoh GR Digital III: Limited to 640 x 480 video at 30 fps - nearly obsolete by today’s standards, more of a bonus feature than a serious video tool.

If video matters, Canon’s offering makes it more of a usable secondary feature.

Real-World Photography Disciplines: Who Excels Where?

Price-to-Performance: What’s Your Money’s Worth?

• The Canon SX620 HS, at roughly $279 new (or cheaper used), is an all-rounder compact superzoom that offers excellent value for casual shooters wanting reach and Wi-Fi connectivity.
• The Ricoh GR Digital III, priced at about $399 or more due to scarcity, is less versatile zoom-wise but rewards photographers craving high image quality, manual controls, and RAW files in a pocket package.

Neither camera is cutting-edge in 2024, but each occupies a special niche.
