Canon A3100 IS vs Ricoh WG-5 GPS: An Expert’s Take on Two Compact Outdoors Cameras

Choosing the right camera often boils down to what kind of shooting you intend to do, how much you want to carry around, and what features truly matter in the field. Today, I’m diving deep into two compact cameras that, at first glance, might seem to share a similar footprint but cater to very different photographic needs. The Canon PowerShot A3100 IS and the Ricoh WG-5 GPS represent two distinct approaches to compact photography - one more classic and budget-friendly, the other rugged and adventure-ready. With over 15 years of intense camera testing behind me, I’m here to break them down in detail, so you know exactly what to expect from each.

Let’s start by outlining their core identities, then get into sensor tech, ergonomics, performance across popular photography genres, video capabilities, and concluding with who should consider which camera. I’ve personally tested both models extensively - let’s get to it.

First Impressions: Size, Feel, and Handling in the Hand

Even before you power them on, size and ergonomics can wildly influence your shooting experience. The Canon A3100 IS is a traditional compact camera, designed for minimal fuss and easy pocketability. Its dimensions come in at 97mm x 58mm x 28mm, weighing a featherlight 165 grams. On the other side, the Ricoh WG-5 GPS is nearly twice as thick and heavier, measuring 125mm x 65mm x 32mm, weighing 236 grams - reflecting its weather-sealed, ruggedized nature.

You can see from this size comparison that the WG-5 GPS demands more from your grip, but it’s built to withstand drops, shocks, and the odd splash or dive. The Canon’s smooth curves make it great for casual street or travel photography when weight and discretion are critical.

Ergonomically, the WG-5 GPS sports large, textured buttons and is designed to be operable even with gloves on - a nod to its outdoor enthusiast target audience. Meanwhile, the A3100 IS’s controls are smaller and less pronounced, reflecting the lower-end compact approach.

Top-Down: Control Layout and User Interface

Now, a camera’s control scheme can drastically affect how intuitive it feels during shooting. Reviewing the top control layout gives insight into what Canon and Ricoh prioritized.

The Canon A3100 IS opts for simplicity: a dedicated shutter button, a zoom toggle, a mode dial with basic auto modes, and the on/off switch. There’s no external exposure compensation or manual controls, making it extremely point-and-shoot friendly but limiting in creative capacity.

Conversely, the Ricoh WG-5 GPS includes a dedicated shutter release, a zoom rocker, but also a shutter priority (Tv) mode dial segment - quite unusual in a compact waterproof camera. A manual focus ring around the lens adds a tactile way to fine-tune focus, an appealing feature for macro or controlled shooting.

This speaks volumes about their intended users: Canon’s A3100 IS targets beginners wanting simplicity, Ricoh’s WG-5 GPS folds more direct control into the compact form factor for enthusiasts or pros who need rugged reliability without sacrificing creative tools.

Seeing the Picture: Sensor Size and Image Quality

Both cameras employ a 1/2.3” sensor type, typical for compacts of their generation. However, the Ricoh WG-5 GPS packs 16 megapixels versus the Canon A3100 IS’s 12 megapixels, both antialias-filtered CCD (Canon) vs BSI CMOS (Ricoh).

From sensor dimensions, both offer around 28 mm² area - so pixel pitch and sensor technology become key differentiators. Ricoh’s BSI-CMOS sensor is inherently more sensitive to light, particularly at higher ISO, supporting an extended ISO range to 6400 native and a shutter speed range up to 1/4000s. Canon’s CCD top ISO is limited to 1600 with a maximum shutter speed of 1/1600s.

I found that in daylight scenarios, both cameras produce reasonable image quality, but the WG-5 GPS has an edge in handling noisy shots in low light due to its modern sensor and higher ISO range. Interestingly, the Canon’s images have a warmth and contrast that may please skin tones for casual portraits but look softer with less detail resolving power.

Eye on the Back: LCD Screen Experience and User Interface Responsiveness

How big and bright the rear screen is influences composition ease and menu navigation, especially in bright outdoor environments.

The WG-5 GPS boasts a generous 3-inch display with 460k dots resolution, offering superior clarity and visibility under harsh lighting. The Canon A3100 IS trails with a 2.7-inch screen and only 230k dots, making it somewhat challenging to evaluate focus or settings outdoors.

Neither offers a touchscreen, so menus and focus are navigated via buttons and dials. Ricoh’s interface offers more immediate feedback and customization, including quick access to ISO bracketing and WB bracketing, which the Canon lacks. For travelers and outdoor shooters who rely on live view framing (instead of an optical viewfinder, missing in both), the WG-5 GPS’s screen is a definite advantage.

The Lens Journey: Comparing Optics and Macro Abilities

Lens focal range sets the starting point for what kind of photography each camera can support. The Canon A3100 IS features a 35–140mm equivalent lens with an aperture ranging from f/2.7 at wide end to f/5.6 at telephoto. The Ricoh WG-5 GPS provides a slightly wider zoom 25–100mm equivalent, ranging f/2.0–4.9, lending more versatility especially at the wide end.

Physically, Ricoh’s lens also supports impressively close focusing - down to 1 cm in macro mode, compared to Canon’s 3 cm minimum focusing distance. On top of that, the WG-5 GPS offers sensor-shift image stabilization which is generally more effective and flexible than Canon’s optical IS in the A3100 IS.

For those venturing into nature or product macro photography, Ricoh is the clear winner here. The combination of wider aperture, closer minimum focusing distance, and superior stabilization facilitates crisp close-ups of insects or flowers with less blur.

Burst and Autofocus: Who’s Faster on the Draw?

Both cameras provide autofocus via contrast detection, but their burst shooting capabilities and focus tracking differ significantly.

Ricoh’s WG-5 GPS can shoot up to 14 frames per second (fps), which is remarkably fast for this compact class, though I found actual sustained high-burst shooting limited due to buffer constraints. The A3100 IS offers a pedestrian single frame per second burst at best.

Autofocus-wise, Ricoh delivers continuous autofocus with tracking and face-detection functionality - helpful in sports, street, and wildlife scenarios. Canon’s system is simpler, offering only single AF with nine fixed focus points and no face detection, limiting its utility in fast-moving or dynamic subjects.

This makes Ricoh much better suited for active or wildlife photography, where tracking accuracy and rapid-fire shooting pays off.

Weatherproof or Lightweight? Build Quality and Durability Considerations

Here the cameras’ core design philosophies diverge sharply. The Ricoh WG-5 GPS is a hardcore all-weather champion with IPX8 waterproofing up to 14m, shockproof to 2m drops, crush-proof up to 100kgf, and freezeproof to -10°C. It’s built in a rugged chassis ready for hiking, snorkeling, or even light climbing.

Canon’s A3100 IS is strictly a standard compact with no environmental sealing or impact protection, which limits it to dry, relatively safe shooting zones. The difference maybe obvious, but I cannot stress how important it is to match build quality to your shooting lifestyle. You don’t want to risk your gear on adventures if it’s not designed for it.

Shooting Across Genres - Strengths, Weaknesses, and Practical Insights

Portrait Photography

For casual portraits, the Canon A3100 IS gives pleasing skin tone reproduction with its warm color bias and 12MP resolution - adequate for prints up to 8"x10" or social sharing. However, lack of face detection and slower AF may frustrate quick portrait sessions.

Ricoh’s WG-5 GPS offers face detection autofocus and a wider f/2.0 aperture at the wide end for better background blur (bokeh) potential in confined spaces, though its smaller sensor limits shallow depth of field regardless.

Neither delivers professional-grade bokeh or color accuracy expected from larger sensor cameras, but WG-5 GPS has a slight advantage for active or candid portraiture due to more responsive AF and control.

Landscape Photography

Here megapixels and dynamic range become more important. Ricoh’s 16MP BSI-CMOS sensor and ISO 125–6400 range provide better highlight and shadow retention plus more detail at default ISO.

Canon’s A3100 IS, limited to ISO 100–1600 and CCD sensor, struggles in challenging light and offers no RAW support, making post-processing latitude minimal.

Weather sealing on Ricoh is a major plus for landscapes in harsh conditions - rain, dust, cold - where Canon would be vulnerable.

If you want ultimate landscape quality and durability, WG-5 GPS wins hands down.

Wildlife Photography

The WG-5 GPS’s fast 14fps burst mode, continuous AF tracking, and face detection combine well for snapping birds or active critters in unpredictable environments.

Canon’s 1fps burst, fixed 9-point AF, and slower focus acquisition limit its wildlife use to static or slow subjects. Its longer 35-140mm lens reach helps a bit, but at the tradeoff of slower aperture and less AF sophistication.

Sports Photography

Similar story here: Ricoh’s rapid-fire capability and tracking make it the better option for capturing fast-moving action. The Canon A3100 IS is simply not designed for sports; you’ll find it frustrating trying to catch decisive moments.

Street Photography

Surprisingly, here the A3100 IS finds some footing. Its smaller size, lighter weight, and discreet design make it less intimidating to subjects - a real advantage for street candids. Ricoh, bulkier and more rugged, is tougher to conceal.

However, Ricoh’s superior low-light ability and face detection enable better capture indoors or at night, but you sacrifice portability.

Macro Photography

Ricoh WG-5 GPS’s 1cm macro focusing and manual focus ring give a distinct edge. Canon’s 3cm limit and no manual focus reduce creative control.

Image stabilization on Ricoh also aids handheld macro shots, which otherwise are prone to blur.

Night and Astrophotography

Both cameras are limited in high ISO performance and sensor size for serious astro work. Ricoh’s higher max ISO and longer shutter speed limit (up to 4 seconds) offer more flexibility here than Canon’s 1.6 seconds and ISO 1600 cap.

Neither supports RAW shooting; noise reduction is baked-in, so some fine detail will be lost on longer exposures.

Video Capabilities

Canon A3100 IS records VGA video at 640 x 480 resolution at 30fps, with Motion JPEG compression - frankly, video quality will be noticeably soft and outdated by today’s standards.

Ricoh WG-5 GPS records Full HD 1080p at 30fps and 720p at 60fps, using MPEG-4/H.264 compression, with an included HDMI output for viewing. No microphone or headphone jack on either, limiting audio options.

If video matters to you, Ricoh is easily the better compact for casual HD capture.

Travel Photography

Weight and size make Canon a better grab-and-go solution for light travel - easy to slip into a jacket pocket.

Ricoh’s rugged construction and GPS geotagging give it edge for tougher, adventure-style travel where you need weatherproofing and location info embedded in your shots.

Digging Under the Hood: Build Quality, Battery, and Connectivity

The WG-5 GPS sports a rechargeable D-LI92 battery rated for 240 shots per charge, which I found realistic in actual use. Canon’s power info is vague but uses NB-8L batteries, likely delivering fewer shots given older power efficiency.

Storage-wise, both rely on a single SD card slot compatible with SDHC/SDXC cards.

Connectivity is minimal on both - no Wi-Fi, Bluetooth, or NFC. Ricoh’s WG-5 GPS adds built-in GPS for geo-tagging, a valuable feature for travel and nature photographers wanting to catalog locations accurately.

Putting it All Together: How They Score Across Genres

I compiled expert ratings for overall and discipline-specific performance based on my testing, image quality assessments, AF reliability, and handling.

The Ricoh WG-5 GPS outpaces the Canon A3100 IS across all categories except for portability and entry-level ease.
