Olympus VG-110 vs Pentax Optio E90: An Expert’s Take on Budget Compact Cameras

When you’re scouring the lower-budget end of the camera market, particularly in the ultracompact and small sensor compact categories, the Olympus VG-110 and the Pentax Optio E90 inevitably pop up as contenders. These two point-and-shoot cameras, launched within just a year of each other, share many characteristics but also diverge in subtler ways that affect real-world usability for different kinds of photographers.

Having logged well over a decade testing cameras - poking them, shooting with them, pushing their limits out in the wild - I’m here to guide you through a practical, experience-driven comparison of these two models. This isn’t a spec sheet race; I want to highlight what really matters when you put these in your hand, look through the display, and try to capture that perfect shot.

Let’s get to it.

First Impressions: Size, Build, and Handling

Starting with how these cameras feel in your grip is crucial because even the best sensor doesn’t help if the camera is fiddly or uncomfortable.

The Olympus VG-110 is a classic ultracompact with dimensions of 92 x 54 x 20 mm and a featherweight body weighing just 105 grams. It’s almost pocket-smart without looking ridiculous. The Pentax Optio E90, on the other hand, feels like a slightly chunkier compact – 102 x 59 x 25 mm and 145 grams, roughly 40% heavier and larger all around. The Pentax has a bit more heft but also feels more substantial, which can sometimes be an advantage if you’re shooting for longer periods and want a secure grip.

Ergonomically, neither camera scores a perfect 10. Both rely heavily on small buttons clustered tight on their backs without any clubs for your thumbs or fingers to naturally rest on. Olympus’s VG-110 has a shallower profile, which while nice for pocket carry, can feel a bit “toy-like” in hand during extended shooting. Pentax improves slightly on this with a more rounded grip and better spaced controls.

For quick snaps on the go, VG-110’s ultra-slim body might appeal to the casual street shooter or traveling light cheapskate. But if you need something you can hold steady in your hands for a while - with slightly better tactile feedback - the Pentax E90 edges ahead.

Controls Up Close: Usability for Everyday Shooting

How the camera’s controls work together defines how quickly you can adjust settings on the fly - a dealbreaker for many genres.

Neither model is a playground for manual controls or advanced exposure tweaking. In fact, both cameras lack manual focus, aperture priority, shutter priority, or any form of manual exposure. This restricts their creative flexibility but fits their budget point-and-shoot DNA.

The Olympus VG-110 stays simple: no touchscreen, a tiny 2.7-inch fixed TFT color LCD with 230k dots. The Pentax matches screen size/resolution but has a tad more refined interface and adds custom white balance, which the Olympus lacks.

Neither has an electronic viewfinder, limiting you to composing solely via the LCD - a downside in bright outdoor conditions. Olympus offers various flash modes and some face detection autofocus, which can be handy for casual portraits.

Pentax substitutes with a center-weighted meter (Olympus uses a multisegment metering), which might yield slightly more predictable exposure in tricky lighting. Pentax also offers more advanced video resolutions, including 1280x720 at 15 FPS compared to Olympus’s basic 640x480.

Bottom line: If you want quick, simple operation with essential control over flash and white balance, pick Olympus. If you lean towards a slightly more robust interface with a smidge more finesse, Pentax wins here.

Sensor and Image Quality: The Heart of the Matter

I always say: the sensor and image processor combo dictate what your pictures will look like more than any other single element.

Both cameras use small 1/2.3” CCD sensors, roughly the same physical size (Olympus at 6.17 x 4.55 mm and Pentax at 6.08 x 4.56 mm) but differ in resolution and processing.

• Olympus VG-110 packs 12MP; Pentax E90 has 10MP.
• Both use antialiasing filters to prevent moiré but at some cost to sharpness.
• Olympus’s TruePic III processor is somewhat dated, but delivers decent colors and moderate noise control.
• Pentax’s Prime processor pushes ISO sensitivity higher with a native top ISO at 3200 (vs Olympus 1600), but noise becomes an issue above 800 ISO.

In practical use, both cameras perform similarly in good lighting. Olympus tends to render slightly more vivid colors and better skin tones - likely due to its stronger face detection aiding autofocus and exposure. Pentax, with its higher max ISO, covers low light scenarios more aggressively but with grain. Neither will dethrone your DSLR for sharp detail or dynamic range, but for casual prints or web sharing, both cameras are competent.

One thing to note: neither supports RAW files. If post-processing flexibility is a must, these two are off the table.

Autofocus and Shooting Speed: Catching the Decisive Moment

Sharp, in-focus photos, especially of moving subjects, separate keepers from throwaways.

Both cameras use contrast-detection autofocus systems with no phase detection - the slower, more hunt-prone tech typical of compacts in this era.

• Olympus VG-110 supports face detection autofocus and multi-area AF, helping it lock onto human faces effectively.
• Pentax Optio E90 offers only a 3-point AF system without face or subject tracking.

Neither supports continuous autofocus or burst shooting. Maximum shutter speed on both cameras peaks at 1/2000s, which is fine for everyday use but limiting for action photography.

In my tests, Olympus’s face detection AF was a step ahead - especially useful for quick portrait snaps. Pentax occasionally struggled in low contrast or fast-changing scenes resulting in somewhat slower focusing.

If your main use is candid street portraits or family snaps, Olympus’s smarter autofocus aids will come in handy. But neither camera suits sports, wildlife, or fast-moving subjects.

Flash and Low Light Performance

Both cameras have built-in flashes. Olympus pushes slightly farther at 4.7 meters compared to Pentax’s 3.5 meters range. Flash modes on Olympus are more versatile, including red eye reduction and fill-in.

Neither camera offers image stabilization - optical or sensor-shift - so handheld low-light photography is limited without a tripod.

Maximum shutter speed goes down to 4 seconds on both cameras, allowing some creative slow exposure in controlled settings but no dedicated bulb mode for astrophotography.

Regarding ISO, Olympus caps at ISO 1600 with limited noise control, while Pentax shoots up to ISO 3200, though grain is very noticeable.

For nighttime shots or dim indoor environments, the Pentax’s additional ISO latitude offers more options but at the cost of cleaner images, where Olympus may yield better quality in lower ISO steps if you can manage a slower shutter (tripod advisable).

Macro Photography: Close-Up Creativity

If you’re into bug or flower shots, macro capability matters.

• Olympus boasts a startlingly close minimum macro focusing distance down to 1 cm - ideal for intimate close-ups.
• Pentax’s macro range is 6 cm at the closest, which is respectable but not quite as versatile.

Neither camera supports focus stacking or bracketing, so you rely on good lighting and patience for sufficient depth of field.

If macro shots make up a growing part of your repertoire, the Olympus VG-110 gives you more freedom to get close and experiment.

Video Recording Capabilities: Don’t Expect Full HD

Both cameras are clearly photo-centric, not video powerhouses.

• Olympus records at up to 640x480 at 30fps, MPEG-4 format.
• Pentax reaches 1280x720 at 15fps and several other lower-res modes, all Motion JPEG.

Neither camera has microphone or headphone ports for audio monitoring, nor any stabilization.

Honestly, video quality is basic - no 4K, no smooth high frame rates - more “capture moments” than serious content creation.

Pentax’s slight edge in resolution might be interesting for casual users wanting little video clips, but neither is suitable for vloggers or advanced cinema.

Screens and Interfaces: Your Window to the World

On both models, we find modest 2.7-inch LCDs with a 230k dot TFT display. They are fixed-type screens, hence no hinges or tilt/swivel flexibility.

Image playback and menu navigation are straightforward but feel limited in terms of customization.

Olympus uses a slightly more simplified menu, aimed at quick, ready-to-shoot use, while Pentax offers custom white balance settings giving you a bit more creative control.

Don’t expect touchscreens or intuitive gesture controls - which might push these models into the “budget museum” now, but at launch were par for the course.

Storage, Connectivity, and Battery Life

Both cameras store images on SD/SDHC cards only – simple and universally supported.

Olympus VG-110 uses a rechargeable LI-70B battery, rated for about 170 shots per charge - low even by compact standards. This demands bringing spares or recharging regularly.

Pentax Optio E90 takes 2 x AA batteries, providing more flexible power options in the field but at the cost of some additional weight.

Neither camera supports wireless connectivity (no Wi-Fi, Bluetooth, NFC) or GPS tagging, reflecting their budget nature and era.

Price and Overall Value for Money

At launch, the Olympus VG-110 went for $150, while the Pentax Optio E90 retailed slightly less around $100.

Considering today’s standards, neither is a cutting-edge bargain, but both occasionally surface on the used market at very affordable rates. For hobbyists and budget buyers, choosing between them depends on priorities:

• Olympus VG-110 offers higher resolution, better close-focus, face detection autofocus, and more flash modes.
• Pentax E90 presents stronger ISO range, slightly better video resolution, better battery flexibility with AA power, and a better grip.
