Ricoh WG-20 vs Sony NEX-5T: A Deep Dive Comparison for Enthusiasts and Pros

When photographers look to upgrade or diversify their gear, selecting the right camera depends heavily on intended use, feature needs, and budget. Today, I’m putting two very different but notable models head-to-head: the rugged Ricoh WG-20 waterproof compact and the versatile Sony Alpha NEX-5T mirrorless camera.

Having personally tested thousands of camera models throughout my 15+ years in the industry, I’m excited to share an in-depth comparison based on extensive hands-on experience, real-world performance, and technical analysis. This side-by-side will help you understand which camera best suits your style - from underwater adventures to serious mirrorless shooting.

Let’s dive in!

First Impressions: Size, Handling, and Ergonomics

Before evaluating image quality or features, handling is paramount for practical use. I always start testing by feeling how well a camera fits in the hand, navigating controls, and considering portability.

Ricoh WG-20:
This compact waterproof camera has a small but rugged form factor. Measuring approximately 114 x 58 x 28 mm and weighing just 164 grams, the WG-20 is designed for travel, outdoor, and adventure photographers who need a durable build without lugging heavy gear. Its petite size lets it slip easily into even tight pockets or small bags, appealing for kayaking, snorkeling, or casual hiking.

Sony NEX-5T:
At 111 x 59 x 39 mm and 276 grams, the NEX-5T is a compact mirrorless but slightly larger and heavier than the WG-20. It has more bulk due to its interchangeable lens mount (Sony E), offering greater versatility but less pocket-friendliness. Still, its rangefinder-style design feels balanced and well-appointed for controlled shooting - perfect when you want more grip and direct control over settings.

Hand-on Test Conclusion:
If you prioritize rugged portability and need a camera that can withstand harsh environments, the Ricoh WG-20’s weatherproof and shockproof credentials make it unbeatable here. However, for those seeking ergonomic versatility and the possibility to swap lenses, the Sony NEX-5T offers a more traditional photographic experience.

Control Layout and Interface Usability

The ability to quickly adjust settings directly impacts the shooting experience, especially in dynamic situations.

Ricoh WG-20:
The WG-20’s control is simplified, which aligns with its use case. Buttons and dials are minimal - with no dedicated exposure modes like aperture or shutter priority. Everything revolves around point-and-shoot ease, enhanced by digital image stabilization and a few exposure bracketing options. However, no touchscreen and smaller 2.7" LCD with only 230k resolution means the interface feels dated and less interactive.

Sony NEX-5T:
Here, the interface leaps ahead. The NEX-5T features a fully tilting 3" touchscreen LCD with 922k dots, facilitating intuitive touch focus, menu navigation, and image review. It supports manual, aperture priority, shutter priority, and program auto modes, giving creative flexibility. The electronic viewfinder is absent here but can be added separately for a more traditional workflow. Bi-directional control dials and customizable buttons support quick adjustments during fast-paced shooting.

Summary:
The NEX-5T has a far more interactive and advanced control scheme suitable for anyone serious about photography. The WG-20’s simplicity matches outdoor/user-friendly needs but limits creative customizability.

Sensor and Image Quality: Comparing Raw Potential

Now let’s delve into the image engines powering these cameras - the heart of photographic quality.

Sensor Technology

• Ricoh WG-20: Utilizes a 1/2.3" CCD sensor with a 14MP resolution. This tiny sensor limits dynamic range and noise performance - especially in low light. CCD sensors historically deliver punchy colors but lag behind modern CMOS in efficiency and noise control.

• Sony NEX-5T: Packs a much larger APS-C CMOS sensor (23.4 x 15.6 mm) at 16MP resolution with Bionz processor. This APS-C sensor is over 13 times larger in area than the Ricoh’s sensor, resulting in dramatically better performance for detail, low light, and tonal gradation.

Resolution and Detail

• The NEX-5T’s 4912 x 3264 max resolution gives more room for cropping and large prints without loss.
• WG-20’s 4288 x 3216 pixels, while decent for a compact, simply cannot compete when pixel size, sensor noise, and dynamic range are factored in.

Dynamic Range and ISO Performance

• NEX-5T’s 13 EV dynamic range (as per DxO testing) reveals a robust capacity to retain highlight and shadow details.
• WG-20’s untested but typical for a sensor this size CCD, dynamic range is cramped, and ISO settings above 400 become noisy quickly.

Real-World Observation:
In daylight, WG-20 produces usable images with good color but lacks crispness at pixel level. Indoors or on cloudy days, noise and limited dynamic range become evident. The NEX-5T’s larger sensor delivers clean, sharp images even well into ISO 1600+, and post-processing recovery is smoother.

LCD Display and Viewfinder Experience

The option to review images precisely and compose shots is vital for release confidence.

• WG-20: Fixed 2.7” TFT LCD with low resolution results in less accurate image previews. No viewfinder forces reliance on this small screen, challenging under bright outdoor light.

• NEX-5T: 3” tilting touchscreen LCD with high resolution greatly enhances composition flexibility and in-field review. Optional external electronic viewfinder (not built-in) is available for shooting in bright conditions and when preferring eye-level framing.

Practical Takeaway:
The NEX-5T’s screen and interface provide a vastly superior user experience in checking focus, exposure, and framing. Ricoh’s screen is sufficient for casual snapshots but limited.

Autofocus and Shooting Performance

Autofocus (AF) speed, accuracy, and continuous shooting impact usability across genres.

In Practice:
I found the WG-20’s autofocus is sluggish in anything less than bright settings, particularly frustrating for moving subjects like pets or kids. The NEX-5T’s on-sensor phase detection coupled with contrast AF yields snappy focus lock and excellent tracking, vital for wildlife, sports, and street photography.

Weather Sealing and Durability

If you shoot outdoors often, build robustness may be a deciding factor.

• Ricoh WG-20: Fully waterproof (up to certain depths), shockproof, freezeproof. Designed to conquer harsh environments - immersion, drops, and cold.

• Sony NEX-5T: No official weather sealing or rugged certifications. A relatively durable build for indoor/outdoor day use, but extra care is needed in poor weather.

Who wins here?
No contest: Ricoh WG-20’s environmental sealing is a huge plus for adventure and travel photographers who need a reliable body that won’t quit under wet or rough conditions.

Lenses and Versatility: Fixed vs Interchangeable

• WG-20: Has a fixed 28-140mm equivalent (5x optical zoom) lens with f/3.5-5.5 aperture range. It covers general purpose wide to telephoto but can’t change lenses or upgrade optics.

• NEX-5T: Sony E-mount with access to 121 lenses ranging from fast primes, zooms, macro, fisheye, and specialized glass. This is a tremendous advantage for photographic creativity and technical needs.

If you want macro, wide-angle landscapes, portrait lenses with stunning bokeh, or wildlife telephoto reach, the NEX-5T gives you the options. The fixed Ricoh lens works well for everyday snapshots but won’t satisfy niche genres.

Battery Life and Storage Flexibility

• Ricoh WG-20: Rated for 260 shots per charge using D-LI92 battery, respectable for a compact. Uses SD/SDHC/SDXC cards.
• Sony NEX-5T: A bit better endurance at approximately 330 shots with a larger NPFW50 battery. Offers a choice between SD cards and Memory Stick Pro formats.

Overall, battery life is quite similar, though the NEX-5T’s larger size accommodates a bigger cell and more efficient power management options.

Video Capabilities

• Ricoh WG-20: Records max HD 720p video with a max frame rate of 30fps in Motion JPEG format. Basic video suited for casual use.
• Sony NEX-5T: Records Full HD 1080p at up to 60fps in advanced codecs (AVCHD, MPEG-4, H.264), delivering better quality. No 4K but ample options for creative video shooters.

Neither has microphone or headphone jacks, so audio is limited. That said, the NEX-5T’s video quality is clearly superior, making it a better hybrid still/video shooter.
