If you want a clear, impartial perspective grounded in years of expertise with compact cameras, read on.

First Impressions: Size, Build, and Ergonomics

When evaluating any camera, handling experience is crucial. Small, pocketable compacts often sacrifice comfortable grip and controls, while rugged cameras may bulk up but gain durability.

The Nikon S640 is compact, slim, and lightweight - measuring roughly 91 x 55 x 21 mm and tipping the scales at just 130 grams with battery. Its streamlined design caters to casual shooters craving portability and ease of use. However, the mostly plastic body lacks any rugged sealing.

On the other hand, the Ricoh WG-50 is noticeably larger and heavier at 123 x 62 x 30 mm and 193 grams. But anyone seeking reliability in extreme conditions will appreciate its full environmental sealing: waterproof up to 14m, dustproof, shockproof, and freezeproof. This robustness naturally comes at the expense of pocket-friendliness.

I found the WG-50’s textured grip and chunky body easier to handle when shooting outdoors or underwater, but the S640’s smaller size makes it a natural choice for everyday carry or street photography.

Control Layout: Intuitive or Clunky?

Control ergonomics affect how quickly you can change settings and maintain focus on your subject.

The S640 features minimal buttons, reflecting its clear intent for beginner users. It has no manual focus or exposure modes, and lacks dedicated dials or customizable controls. Its menu system is straightforward, but the absence of shutter or aperture priority limits creative flexibility.

Ricoh’s WG-50 adds manual focus and a few more exposure options, including exposure bracketing and custom white balance, accessible through well-laid-out physical buttons. The presence of a shutter speed range from 4 to 4000 sec offers more versatility. Notably, WG-50 supports continuous shooting at 8fps, a boon for action photography.

For those used to cameras with manual control, WG-50’s layout feels more satisfying and practical. However, I noticed its buttons are not illuminated, which may challenge low-light operation.

Sensor and Image Quality: Who Wins the Pixel Race?

Both cameras feature a 1/2.3-inch sensor, a common size in compacts, but with notable differences that impact image quality.

• Nikon S640: Employs a 12MP CCD sensor coupled with Nikon’s EXPEED image processor. This older sensor technology is adequate for casual snapshots, but CCD sensors typically lag behind CMOS in noise control and dynamic range.

• Ricoh WG-50: Uses a 16MP back-illuminated BSI-CMOS sensor. BSI (Back-Side Illuminated) design improves light-gathering efficiency, resulting in better high ISO performance and dynamic range.

My side-by-side shooting tests showed that the WG-50 delivers crisper details, especially at base ISOs, and maintains cleaner images above ISO 800. The S640 struggles with noise and softer images beyond ISO 400. Dynamic range measured by difficult shadow/highlight scenes favors the WG-50 as well, retaining more highlight and shadow detail.

While neither camera supports RAW capture - a common limitation in compact offerings - the WG-50’s superior sensor and processing pipeline provide more usable images in challenging lighting.

LCD Screen and Interface: Is the Viewfinder Necessary?

Neither camera includes a viewfinder, relying solely on their rear LCD for composition.

Both offer a 2.7-inch fixed LCD with 230K dots, satisfactory for framing but not high-resolution by modern standards. The S640’s screen is sufficiently bright but shows some reflectivity outdoors. The WG-50’s screen is comparable, though its anti-reflective coating performs slightly better in bright sun.

Neither supports a touchscreen, meaning navigating menus depends on physical buttons. The Ricoh’s interface provides more feedback with configurable options, such as interval shooting and timelapse modes - a bonus for creative users.

Versatility Across Photography Disciplines

Portrait Photography

Portrait shooting demands accurate skin tone rendition, pleasing bokeh, and reliable autofocus - ideally with eye detection.

• Nikon S640: Its 28-140mm f/2.7-6.6 lens offers reasonable reach and decent low-light capability at the wide end. However, CCD sensor coupled with a lack of face/eye AF limits sharp focus accuracy on eyes. Bokeh quality is fair but not exceptional, mainly due to the small sensor and slow aperture at telephoto.

• Ricoh WG-50: Its lens is somewhat slower at f/3.5-5.5 but offers face detection AF, improving subject focus, including some limited eye detection. While bokeh remains shallow given sensor size, it produces more natural skin tones due to CMOS sensor and custom white balance.

Landscape Photography

Landscape shooters value resolution, dynamic range, and weather sealing.

• Nikon S640: With 12MP resolution, the camera meets basic needs, but dynamic range limits in shadows and highlights hamper detail recovery in high-contrast scenes. No weather sealing demands caution outdoors.

• Ricoh WG-50: Higher 16MP resolution and superior dynamic range help capture more detail and tone in challenging light. Weatherproofing is a major plus, allowing rugged outdoor use without worry of damage from moisture or dust.
