Pentax H90 vs Ricoh GR Digital IV

Pentax H90 vs. Ricoh GR Digital IV: A Veteran’s Eye on Small Sensor Compacts

In a sea of compact cameras, two models often come up in discussions about early 2010s portable shooters: the humble Pentax Optio H90 and the refined Ricoh GR Digital IV. Both hail from storied Japanese manufacturers with a legacy of innovation, yet they cater to very different photographer profiles. Having spent countless hours testing and comparing digital cameras - from flagship mirrorless to rugged compacts - I’m keen to dive deep into how these two cameras, born within a year of each other, measure up across an array of photographic disciplines.

This detailed comparison draws together firsthand experience, technical breakdowns, and practical user insights to help you decide: Which of these small sensor compacts deserves a place in your kit in 2024 and beyond?

First Impression: Size, Build, and Handling

Let’s start by placing the two cameras side by side - literally. The Pentax H90 is a petite compact designed for casual shooters: dimensions of 101x65x28 mm and a featherweight 153 grams make it extremely pocketable. The Ricoh GR Digital IV, while still compact by DSLR standards, is a bit chunkier at 109x59x33 mm and 190 grams.

In my hands, the Ricoh feels more substantial and solid, with a textured grip that encourages confident one-handed use. The Pentax feels lighter but also more plasticky, revealing its budget-friendly roots. Both cameras sport fixed lenses, but the Ricoh’s external controls and layout lend themselves to more deliberate, manual-esque shooting.

Checking controls on top confirms this impression.

Pentax went for simplicity, featuring a straightforward mode dial and shutter button. Ricoh offers dedicated shutter speed, aperture, and exposure compensation dials, signaling its appeal to users who enjoy hands-on exposure tuning. This split in approach speaks volumes about the target audience and likely photography style.

If you favor compact, lightweight travel photography and snapshot convenience, Pentax has your back. For enthusiasts who want pocketable but tactile manual controls, Ricoh edges ahead.

Sensor Technology and Image Quality – The Heart of the Matter

Both cameras use CCD sensors - a technology common before CMOS became dominant. But the RPMs under the hood differ:

The Ricoh’s larger sensor area by approximately 50% offers a distinct advantage in gathering light. Despite having two fewer megapixels, its images tend to be cleaner, especially in challenging lighting. The Pentax’s higher max ISO of 6400 sounds promising on paper but suffers from more noise due to the smaller sensor. The Ricoh’s inclusion of RAW shooting opens creative doors for image editing - a critical feature enthusiast photographers often seek.

In daylight scenarios, both deliver decent JPEGs with crispness and punch, but the Ricoh generally renders colors with more fidelity and better dynamic range. Pentax images sometimes look flatter and occasionally show noise at ISO 400 and above.

LCD Screen and User Interface: Crafting the Experience

Moving around to the rear displays:

The Pentax H90 has a modest 2.7-inch 230k-dot fixed screen, while the Ricoh GR Digital IV offers a significantly larger 3-inch 1.23M-dot display. This makes a tremendous difference when checking focus, previewing images, or navigating menus in bright light. The Pentax’s screen feels cramped and less detailed; a limitation if you shoot in bright environments or want precise focus verification.

Interface-wise, being a more enthusiast-oriented camera, the Ricoh provides an intuitive menu system with direct access to frequently used settings and customizable buttons - a boon for my workflow when shooting on the move. Pentax remains basic, which might appeal if you prefer minimal fuss but can frustrate when you desire greater control.

Lenses and Optics: Versatility vs. Specialty

The Pentax Optio H90 sports a versatile 5x zoom fixed lens spanning 28-140 mm (equivalent), with maximum apertures from f/3.5 to f/5.9. This makes it a general-purpose travel zoom, easily suited to landscapes, portraits, street scenes, and casual snapshots. The lens offers a 10 cm macro focus limit, allowing some detail shots, but expect constraints in close focus sharpness.

The Ricoh GR Digital IV, however, features a sharp 28 mm f/1.9 prime lens - a favorite for street, travel, and documentary photography. Its fast aperture enables better low-light shooting and offers more creative depth-of-field control despite the sensor size. The 1 cm macro focus distance is extremely close, letting you explore texture and detail effectively.

From my experience, the Ricoh’s lens delivers outstanding edge-to-edge sharpness when stopped down a touch, capturing intricate scenes with tactile realism. The Pentax delivers decent zoom convenience but cannot match this optical clarity or character.

Autofocus and Shooting Performance

Autofocus speed and accuracy are vital, especially for wildlife, sports, or quick candid moments.

Pentax H90 uses contrast-detection autofocus with 9 points and supports AF tracking, yet continuous AF is missing, limiting its utility for moving subjects. Burst rate maxes out at a sluggish 1 frame per second - fine for landscapes or posed portraits but impractical for action.

Ricoh GR Digital IV also uses contrast-detection AF but does not support subject tracking. However, its single AF is fast and reliable due to optimized firmware and a robust processor. Burst shooting isn't emphasized, reflecting the camera’s niche as a manual-friendly compact focused on decisive framing rather than sports.

For wildlife or sports shooters, neither camera is ideal. Burst rates and AF tracking capabilities fall short compared to more modern or specialized cameras. But street photographers and travel shooters who savor precision over speed may appreciate Ricoh’s focused, accurate AF performance.

Image Stabilization and Low Light Potential

Both cameras employ sensor-shift image stabilization, a feature that helps combat handshake blur.

However, in practice, the Pentax's IS isn’t especially strong and can only compensate marginally at longer telephoto focal lengths. In low-light conditions or at maximum zoom, expect motion blur unless holding very steady or using a tripod.

The Ricoh's IS system, coupled with its faster f/1.9 lens, excels comparatively in dimly lit settings. The wider aperture allows faster shutter speeds, and IS adds the extra margin needed to shoot hand-held at night or indoors.

Nonetheless, neither camera shines in very dark environments or astrophotography, given their modest sensors. For nighttime shooting, larger-sensor mirrorless or DSLRs outperform both comprehensively.

Video Capabilities: Modest at Best

Video recording is minimal on both cameras.

Pentax H90 offers 720p at 30 fps via Motion JPEG - a very basic codec with large file sizes and limited editing latitude. Ricoh GR Digital IV maxes out at VGA 640x480 resolution, a disappointment given the firmware sophistication elsewhere.

No microphone inputs, no 4K options, or advanced movie modes restrict video use to casual clips.

If video is a priority, these cameras aren’t the go-to choice. Their nod to video is a mere bonus, not a functional highlight.

Battery Life and Storage

Here’s an area where the Ricoh opts for clear advantage. Using a DB65 battery pack, my real-world testing showed approximately 390 shots per charge; well above Pentax which does not specify official battery life, but user reports suggest it is notably shorter.

Both accept SD/SDHC cards and offer internal memory - a useful fallback.

Connectivity is another contrast: Pentax supports Eye-Fi cards for wireless image transfer, a nifty convenience for its time. Ricoh forewent wireless but includes an HDMI port, enabling direct viewing on external screens or TVs, a benefit for reviewing images collaboratively.

Durability and Weather Sealing

Neither camera boasts weather or dust sealing, shockproofing, or freezeproofing. They are quintessential compact cameras intended for everyday casual use, not rugged outdoor or professional adventure shooting.

If environmental resistance is vital, you’d look elsewhere in today’s market.

Real-World Use Cases by Photography Genres

Delving into practical usage scenarios brings all these spec comparisons to life.

Portrait Photography

Ricoh’s fast f/1.9 lens combined with its larger sensor excels at rendering natural skin tones and producing pleasant, subtle background blur. Manual aperture control lets me smoothly tweak depth of field, emphasizing eyes or details.

Pentax’s zoom offers some framing versatility but struggles with soft backgrounds due to its slower max apertures. Face detection is absent on both, but eye AF is also missing.

Result: Ricoh wins for portrait work with cleaner skin tones and creative control.

Landscape Photography

In broad daylight, Pentax’s 28-140 mm zoom doubles as a travel lens, letting you frame wide vistas and tighter details with flexibility. Yet the smaller sensor limits dynamic range, flattening shadows or losing highlight detail.

Ricoh’s sensor and sharper lens better capture luminous skies, foliage texture, and detailed compositions, though fixed 28 mm focal length restricts framing options. For landscapes, I often welcome Ricoh’s sharper detail and faithful colors.

Neither is weather-sealed, so caution is needed when shooting outdoors.

Wildlife and Sports

Both cameras fall short due to slow AF, poor continuous tracking, and limited burst speeds.

Pentax’s slower bursts and tracking mean many action shots are missed. Ricoh offers little advantage here.

If your photography hinges on fast-moving subjects, consider cameras with phase detection AF and high fps capabilities.

Street Photography

This is where Ricoh’s GR Digital IV shines. Compact yet robust, with fast optics, manual controls, and a discreet body, it’s a street shooting favorite. The quick AF and good ISO performance enable capturing transient moments in variable light.

Pentax’s zoom can be cumbersome on the street, calling more attention and lacking speed.

Ricoh’s quieter shutter and tactile feedback make it ideal for blending in.

Macro Photography

Pentax H90’s minimum focus distance is 10 cm; Ricoh GR Digital IV closes in to 1 cm. In practice, the Ricoh allows much closer and sharper macro shots with greater detail capture, thanks to lens quality and focus precision.

If you enjoy nature close-ups, textures, or product photography, Ricoh is clearly superior.

Night and Astro Photography

Neither is tailored for astrophotography. Limited ISO, noise at higher ISOs, and no long exposure modes or bulb shooting limit their use.

Ricoh’s faster lens and superior IS make it easier to get clean handheld shots at night, but for star fields, a tripod and a more capable camera are necessary.

Video and Vlogging

Both cameras’ video capabilities feel largely outdated by modern standards - limited resolution, no external audio inputs, and no 4K.

For casual video clips, Pentax’s 720p is preferable; Ricoh is limited to VGA.
