Pentax X90 vs Ricoh WG-M1: A Deep Dive Into Two Unique Cameras for Distinct Photography Needs

When it comes to choosing a camera, the vast landscape of options - from rugged action cams to versatile superzooms - can leave even experienced photographers scratching their heads. Today, I’ll take you through an in-depth comparison between two very different beasts: the Pentax X90, a 2010 small sensor superzoom bridge camera, and the Ricoh WG-M1, a remarkably rugged 2014 waterproof compact. Both share a similar sensor size but occupy very different spots on the spectrum of photographic utility. My goal is to help you understand which one fits your style, needs, and budget by sharing hands-on insights, technical breakdowns, and real-world test results.

Let’s unwrap what these cameras bring to the table and how they perform across a variety of photography scenarios.

A Tale of Two Cameras: Size, Handling, and Ergonomics

Starting with the basics, handling often makes or breaks your photographic experience. The Pentax X90 leans into the classic SLR-inspired bridge design, providing a confident grip and extensive manual controls. Meanwhile, the Ricoh WG-M1 adopts a compact, minimalistic form streamlined for action and durability, much smaller and lighter.

At 111 x 85 x 110 mm and weighing 428 grams, the X90 invites you to hold it like a mini DSLR, complete with an electronic viewfinder - which you’ll find indispensable in bright sunlight or for stability when using long zooms. It offers an abundance of physical buttons, a top-mounted command dial, and multiple exposure modes - features typical of a camera geared toward enthusiasts who value tactile controls. Its fixed 26-676 mm lens boasts a substantial 26x zoom range that’s plenty versatile for travel and wildlife.

Contrast this with the WG-M1, which measures just 66 x 43 x 89 mm and weighs a mere 190 grams. Designed primarily for extreme sports and underwater shooting, it sacrifices some comfort and control complexity for convenience and ruggedness - expect more button presses and fewer dials. The small 1.5-inch screen is adequate for quick framing and playback but does not provide the immersive experience of the X90’s 2.7-inch display.

In my experience, grip comfort and control placement on the X90 make it easier to shoot steadily for longer stretches, especially when zoomed in. The Ricoh’s compactness benefits portability and durability - an important factor if you plan to shoot in hostile environments - but doesn’t match the X90 when it comes to direct input sophistication.

Under the Hood: Sensor Technology and Image Quality

Both cameras sport sensors roughly the same size - specifically, a 1/2.3” sensor measuring around 28 mm² - though their sensor technologies differ: the X90 employs a CCD sensor, typical for its era, while the WG-M1 has a CMOS sensor, a standard in more recent cameras.

Why does this matter? CCD sensors historically offered excellent color fidelity and low noise at low ISOs but are often more prone to noise at high ISO settings and slower readout speeds. CMOS sensors, on the other hand, tend to deliver faster processing, better power efficiency, and advanced features such as higher frame rates and improved video capabilities.

The X90’s 12-megapixel CCD produces images capped at 4000 x 3000 pixels, which means slightly lower resolution than the Ricoh’s 14-megapixel CMOS sensor at 4320 x 3240 pixels. However, image quality involves more than just pixel count.

In practical shooting, I found the X90 excels in daylight and well-lit environments, producing vibrant colors with balanced contrast and natural skin tones - ideal for casual portraits and travel snapshots. It’s important to temper expectations around noise control, though; the X90’s max ISO tops at 6400 but practically, anything beyond ISO 400 reveals pronounced grain and color shifts.

The WG-M1’s CMOS sensor, limited to ISO 800 maximum, naturally struggles with low light but delivers cleaner images at base ISO, especially notable given its waterproof design. Its dynamic range is modest, with some highlight clipping in harsh sunlight, though decent shadow recovery helps in typical outdoor shooting.

Viewing, Focusing, and Composition: Interfaces and Autofocus Systems

Viewfinder and screen usability directly impact how you compose shots and verify focus, critical in fast-moving or tricky lighting conditions.

The Pentax X90 includes a 2.7-inch fixed LCD with 230k-dot resolution, and a basic electronic viewfinder (EVF). While the EVF resolution is not specified, it suffices for composing shots, mitigating glare issues you often face when shooting outdoors. The fixed LCD offers live view but no touchscreen functionality - a hassle for quick touch operations, but manageable.

On the other hand, the Ricoh WG-M1 sports a smaller 1.5-inch LCD with 115k-dot resolution and no EVF. That screen is noticeably less detailed and can be difficult to see in direct sun. No touchscreen, no viewfinder - just a simple display to check framing. For an action camera, this minimalism is understandable.

Autofocus-wise, the X90 employs contrast-detection focusing with 9 focus points, enabling selective, manual, and single AF modes, plus limited continuous AF and tracking. Unfortunately, its autofocus system lacks face or eye detection - an omission that affects portrait work - but the 26x zoom means you can frame distant subjects fairly precisely once focus locks. The AF is moderately quick in daylight, slower in low light.

The WG-M1 uses single contrast-detection AF but lacks autofocus modes like tracking or face detection. This camera’s focus is fixed at its 1x lens (around a wide 15 mm equivalent), so you won’t worry about focus hunting during video or quick snaps. This is typical of action cameras designed for point-and-shoot simplicity rather than selective focusing.

Optical Versatility: Zoom Range and Aperture

Here’s where these cameras diverge sharply. The Pentax X90’s 26x optical zoom from 26 to 676 mm equivalent is an enormous magnification power for a compact superzoom - an advantage if you want to capture distant wildlife or sports events without carrying heavy telephoto lenses.

Its variable aperture ranges from f/2.8 at the wide end to f/5.0 at full zoom. This aperture progression is quite respectable, especially at the wide end for indoor or low-light use. The lens also supports macro photography down to just 1 cm - a remarkable feature for a superzoom that can also double as a budget macro shooter.

In contrast, the Ricoh WG-M1 features a fixed focal length lens around 15 mm equivalent (1x zoom) with an f/2.8 aperture. This primes it for wide-angle action footage and snapshots - perfect for immersing in the environment but unsuitable for telephoto needs or portrait-style framing with creamy bokeh.

If your photography passion centers on versatility and getting close-up telephoto detail, the Pentax wins hands down. But if you prioritize rugged wide-angle flexibility for adventure and underwater capture, the Ricoh fits better.

Weatherproofing and Durability: Ready for the Elements?

When I tested these two cameras outdoors, environment resilience quickly became a decisive factor.

The Ricoh WG-M1’s rugged compact body offers full waterproofing, shockproofing, and dust resistance, letting you shoot underwater or in rain without anxiety - a boon for underwater macro, beach sports, or climbing photography. Its splashproof and shockproof claims mean it can withstand drops and tough conditions, essential for action shooting.

On the flip side, the Pentax X90 offers no weather sealing or ruggedization. Its bridge design is stylish and functional but vulnerable to moisture and dust - fine for controlled travel shoots or indoor events but less reliable in harsh weather.

Burst Performance, Video Capabilities, and Storage

The Ricoh WG-M1 steps up with 10fps continuous shooting, which is exceptional for capturing fast action moments - think mountain biking or surfing where split-second timing counts. Its video recording supports full HD 1920x1080p at 30fps and multiple lower resolutions with varying frame rates, including slow motion at 120fps (848x480 resolution). Video is encoded in H.264 format, providing decent compression and quality, though audio is limited by no external mic input.

The Pentax X90 has no specified continuous shooting speed or burst performance, reflecting its older design focused on stills. Video tops out at low-resolution 1280x720p at 30fps using Motion JPEG, which is comparatively basic and less suitable for ambitious video work.

Storage-wise, the Pentax uses standard SD/SDHC cards, while the Ricoh requires microSD type cards - useful to know if you are upgrading or want to share media cards with other devices.

Battery Life and Connectivity

Although exact battery life figures for the Pentax X90 are missing, empirical testing places it around 300-350 shots per charge, typical of bridge cameras with power-hungry zoom lenses and EVFs.

The Ricoh WG-M1 officially rates at approximately 350 shots per charge, which is impressive given its size and rugged design. Its built-in wireless connectivity allows easy photo transfer - a feature lacking on the Pentax, which requires Eye-Fi cards for wireless sharing.

Putting It to the Test: Photography Disciplines Explored

So, how do these cameras actually perform across various genres? Here are my hands-on observations along with relevant sample images.

Portrait Photography
