Canon SX620 HS vs Ricoh GXR GR Lens A12 28mm F2.5: An Expert’s Comprehensive Camera Comparison

Choosing the right camera can be one of the most consequential decisions for photography enthusiasts and professionals alike. After countless hours testing, shooting in varied real-world scenarios, and analysing technical data, I want to share a thorough comparison of two very different yet intriguing cameras: the Canon PowerShot SX620 HS and the Ricoh GXR GR Lens A12 28mm F2.5. While they may cater to distinct photographic philosophies and user needs, this comparison reveals how each stands up through the lens of practical use and core performance.

I’ll break this down with a sharp focus on in-the-field capabilities, tech insights, value for money, and who should seriously consider each camera. Along the way, expect honest assessments informed by hands-on experience with thousands of cameras tested over more than 15 years.

Let’s dive in.

First Impressions & Build: Compact Convenience vs. Rangefinder Body

When I first handled both the Canon SX620 HS and Ricoh GXR GR Lens A12, their physical presence reconfirmed their fundamental design philosophies.

The Canon SX620 HS is a compact superzoom with a petite footprint measuring just 97 x 57 x 28 mm and tipping the scales at 182 g. It’s a true point-and-shoot performer designed for portability, convenience, and vast zoom range. Its light weight makes it an unobtrusive travel companion - or a grab-and-go daypack essential.

In contrast, the Ricoh GXR GR delivers a rangefinder-style mirrorless body (113 x 70 x 56 mm, 140 g), sporting a more substantial and tactile feel that is comfortable for longer shooting sessions. The heft and shape better match serious photography routines where operation precision and control matter more than being small enough to disappear in your pocket.

While the Canon favors convenience, the Ricoh signals serious intent. If you prize ergonomics for deliberate shooting, you’ll appreciate the Ricoh’s form factor.

Control layouts further underline their use cases: the Canon has a simplified control scheme with fixed lenses and basic modes. Meanwhile, the Ricoh provides manual exposure modes plus shutter and aperture priority - all essential for creative freedom. This speaks to two ideologies: one aims at instant capture with ease, the other at crafting photos through attentive control.

Sensor & Image Quality: Big Sensor Wins Low-Light & Dynamic Range

A critical battle in image quality boils down to sensor size and processing prowess. Here, the Ricoh GXR GR's APS-C sensor (370.52 mm²) dwarfs Canon’s SX620 HS’ 1/2.3" sensor (28.07 mm²) by more than tenfold in area.

The Ricoh’s larger sensor naturally captures more light, which translates directly to better image quality - especially noticeable in noise control, dynamic range, and color fidelity. While the Canon’s 20 MP resolution at 1/2.3" sensor lets it produce good images in bright daylight and casual shooting, its smaller sensor struggles as ISO climbs beyond base 80-100. I regularly find noise creeping in past ISO 400, limiting creative latitude in low-light.

By contrast, the Ricoh’s 12 MP APS-C sensor, though lower in megapixels, provides superior color depth and cleaner files at high ISO, capped at 3200 natively. The larger pixel pitch means users can trust these files for professional-level output - in medium print sizes, at least.

Considering dynamic range, the Ricoh’s sensor enables better recovery of shadows and highlights during editing. The Canon, with its smaller sensor and DIGIC 4+ processor, shows limited room for heavy post-processing but suffices for casual social media and travel photos.

If image quality is paramount and you often shoot ambient light, night scenes, or in challenging dynamic ranges (think landscape sunrises), the Ricoh clearly pulls ahead.

Focusing Systems: Flexible Superzoom vs. Precision Prime Lens

Autofocus performance impacts every type of photography, from portraits to wildlife. Let’s see how these two differ in AF capability and lens design.

The Canon SX620 HS employs a hybrid AF system with nine contrast-based focus points and face detection. Despite being contrast-detection only (no phase-detection), it achieves decent speed in bright conditions and supports AF tracking - though only at a modest 2.5 fps burst speed.

Crucially, its 25-625mm zoom (25x telephoto equivalent) with optical image stabilization lets you quickly frame distant wildlife or sports action without packing extra lenses. This versatility is key for casual shooters who want vast reach in a pocketable body.

On the Ricoh side, the fixed 28mm f/2.5 lens means autofocus is focused on precision rather than range. It lacks AF tracking and phase detection, relying on contrast AF for single shots at a faster continuous shooting speed of 5 fps. For street, environmental portraits, and landscape work, its AF suffices; however, it’s unsuited for distant wildlife or fast-moving subjects.

The lens itself is a high-grade prime, known for razor-sharp results with a fast aperture ideal for shallow depth of field effects.

If your photography demands speed and telephoto reach (e.g., birds, sports), the Canon’s autofocus and zoom capacity will serve better. For precision-focused, artistic shots emphasizing sharpness and background separation, the Ricoh prime shines.

Handling and User Interface: Intuitive Simplicity vs. Manual Control

Turning to usability: ease-of-use can make or break your shooting experience, especially on the street or travel.

The Canon SX620 HS offers a 3-inch 922k-dot fixed LCD. Though it lacks touchscreen functionality, menus are straightforward, designed for point-and-shoot accessibility. There is no viewfinder, which can be limiting under bright outdoor light. However, image stabilization helps keep shots sharp hand-held.

In contrast, the Ricoh’s 3-inch 920k-dot TFT LCD lacks touchscreen and does not include a built-in viewfinder (though one is optionally attachable). Its interface is lean and designed for photographers who prefer manual exposure control and quick access to physical dials.

I appreciate Ricoh’s placement of controls for fast, intuitive manual adjustments - critical for crafted results but potentially daunting for beginners.

By comparison, Canon leans into assisting novices, offering scene modes, auto bracketing absence notwithstanding, and reliable face detection.

Choose the Canon for hassle-free operation and travel-friendly simplicity. Choose the Ricoh if manual control is a priority and you’re comfortable with less automation.
