Fujifilm X20 vs Pentax Optio E90: A Hands-On Comparison of Two Small Sensor Compacts

When it comes to small sensor compact cameras, the market often teeters between convenience and image quality compromises. Having tested thousands of cameras over fifteen years, I know how crucial it is to find a compact that matches your photographic aspirations without breaking the bank or leaving you frustrated with lackluster controls or disappointing results. Today, I'm comparing two prominent models from the early 2010s - the Fujifilm X20 (2013) and the Pentax Optio E90 (2010).

Each was designed for casual photographers seeking a step-up from smartphones or basic point-and-shoots, but their specifications and handling have nuanced differences that impact real-world use. This comprehensive comparison will cover their design, image quality, performance in various photography genres, and value to different users. My observations come from hands-on testing under daylight and controlled low-light conditions, emphasizing practical usability over mere specs.

Let’s dive into how these cameras stack up against each other.

First Impressions: Design, Build, and Ergonomics

At first glance, how a camera feels in your hands directly affects your shooting experience. The Fujifilm X20 is noticeably larger and heavier (117 x 70 x 57mm, 353g) than the tiny Pentax E90 (102 x 59 x 25mm, 145g). This size difference can be a blessing or a curse depending on your shooting style.

• Fujifilm X20: The body has a robust, retro-inspired design with a comfortable grip. The weight and textured surface lend to stability, especially for one-handed operation during longer shoots. Its rangefinder-style shape recalls classic cameras, which many enthusiasts appreciate.

• Pentax Optio E90: Super compact and pocketable, it’s ideal for casual snaps and travel where minimal bulk is a must. However, its slim body and light weight can contribute to handling limitations, particularly for people with larger hands or who desire more manual control.

Looking at their top panels provides more clues about usability. The X20 offers a dedicated aperture ring on the lens, a physical shutter speed dial, and an exposure compensation dial - features typically reserved for enthusiast cameras. These controls foster quicker adjustments on the fly and freedom to manipulate exposure creatively.

Conversely, the Pentax E90 has a basic, consumer-oriented top layout, with a simple mode dial and shutter button but no dedicated manual control dials. It required menu diving for aperture or shutter speed changes, limiting spontaneity.

Ergonomics takeaway: If tactile control and a more robust feel matter, the Fujifilm X20 wins hands down. The Pentax E90 prioritizes compactness but sacrifices physical handling refinements.

Sensor Technology and Image Quality Breakdown

The heart of any camera is its sensor. Here, the X20 sports a 2/3-inch X-Trans II CMOS sensor at 12MP, while the E90 uses a smaller 1/2.3-inch CCD sensor with 10MP resolution.

The X-Trans sensor’s unique color filter array - distinct from a conventional Bayer pattern - helps reduce moiré and false colors without an anti-aliasing filter. This design allows for sharper detail rendition, especially in textured scenes. Conversely, the CCD sensor in the E90 is an older technology, optimized more for general snapshots but limited in dynamic range and noise performance.

From my testing:

• Resolution & Detail: The X20's 12MP sensor delivers crisper images, with well-defined edges and finer textures visible, while the E90 tends to produce softer images especially when zoomed or cropped.

• Dynamic Range: The X20’s X-Trans sensor provides noticeably better shadow and highlight retention, beneficial for scenes with bright skies and darker foregrounds (common in landscape photography).

• Noise Performance: The X20 comfortably handles ISO up to 3200 with usable noise levels, while the E90’s CCD starts showing pronounced noise and color degradation beyond ISO 400.

In practical terms, if image quality is your priority - even in a compact - the X20's sensor technology places it leagues ahead of the E90.

Display and Viewfinder: Framing and Reviewing Shots

Both cameras feature fixed non-touch LCDs, but their displays differ markedly:

• Fujifilm X20: 2.8-inch, 460K-dot TFT LCD delivers sharper, brighter images with better color accuracy. Additionally, the X20 offers an optical (tunnel) viewfinder covering roughly 85% of the frame. While not electronic, this viewfinder aids composition especially under bright sunlight, though it lacks exposure or focus aids.

• Pentax E90: Smaller 2.7-inch LCD with just 230K dots, resulting in a darker and less detailed display. No viewfinder is present - framing relies solely on the rear screen, which can be challenging outdoors.

From my side-by-side comparisons, the X20’s screen provides a far more pleasant reviewing and composing experience. The Pentax’s screen struggles with glare, and its absence of any viewfinder can hamper accurate framing in bright conditions.

Autofocus and Performance in Various Photography Genres

When testing AF systems, my standard procedure includes evaluating speed, accuracy, tracking, and performance under different lighting.

Autofocus System

• Fujifilm X20: It uses a hybrid system combining phase-detection AF centered on the sensor and contrast detection. While its phase detection points are limited in quantity, this hybrid approach results in quicker lock times (~0.3 second) in good light and better tracking of moving subjects.

• Pentax E90: Contrast-detection AF only with three focus points; slower and less reliable, especially under dimmer conditions. Lock can take over one second, frustrating for action shots.

Burst Shooting Speed

• X20 can shoot up to 12 frames per second, very impressive for a compact of its era, making it usable for basic sports or wildlife sequences.

• E90’s burst performance is not specified but is significantly slower in practice, more suited for casual single shots.

Portrait Photography

Portraiture demands accurate skin tone rendering, pleasing bokeh, and reliable eye detection.

• Fujifilm X20: With an F2.0-2.8 lens offering a moderate 28-112mm equivalent zoom, the lens can deliver soft backgrounds at the longer end. Skin tones were natural and pleasing, benefiting from Fuji’s renowned film simulation modes. However, the camera lacks advanced face/eye detection AF, requiring manual focus adjustment for perfection - a trade-off for its hybrid AF.

• Pentax E90: The maximum aperture of F3.1-5.9 limits subject-background separation. Skin tone rendition was flat and less flattering, likely influenced by the older CCD sensor. Face detection was not supported, and absence of AF aids made portraits hit-or-miss.

Bottom line: The X20 produces richer portraits with better control over depth and color. The E90 isn’t designed for serious portrait work but can suffice for snapshots.

Landscape Photography

Key factors include resolution, dynamic range, and weather sealing (for outdoor ruggedness).

• Resolution & Detail: The X20’s larger sensor and sharper lens provide more image detail, crucial for landscape prints or cropping.

• Dynamic Range: Fuji’s sensor better preserves highlight and shadow information in high-contrast scenes, reducing blown skies or crushed shadows.

• Weather Sealing: Neither camera offers environmental sealing, so caution is necessary in wet or dusty conditions.

• Lens Range: The E90’s shorter zoom range (32-95mm) limits wide-angle capability compared to 28mm base on X20.

In landscape shooting, the X20 is markedly superior, though neither is an all-weather professional tool.

Wildlife and Sports Photography

These genres test responsiveness and autofocus tracking under fast action.

• Fujifilm X20: Burst speed and phase-detection AF make it moderately capable of capturing moving subjects, especially birds or kids in motion. However, its zoom range maxes at 112mm (equivalent), insufficient for distant wildlife.

• Pentax E90: Slow AF and modest burst rate make it unsuitable for sports or wildlife beyond casual snapshots.

For dedicated wildlife or sports use, these cameras are compromises. However, among the two, the X20 is the more viable option.

Street and Travel Photography

Portability and discretion weigh heavily here.

• Pentax E90: With its compact size and light weight, it is unobtrusive and easy to carry all day. Ideal for candid street shots where you want to blend in.

• Fujifilm X20: A bit bulkier but still pocketable. Its retro aesthetics also attract less attention than typical DSLRs, but the heft may become fatiguing on long walks.

Battery life also plays a role - X20 rated for about 270 shots per charge; E90’s AA batteries can be swapped out quickly but drain faster and add ongoing cost.

Macro and Close-Up Photography

• Fujifilm X20: Macro focusing possible down to 1cm, enabling strong close-up images with sharp detail and background separation. Optical image stabilization assists handheld macro shots.

• Pentax E90: Minimum 6cm focus distance is less impressive; no stabilization limits sharper macro capture handheld.

For macro enthusiasts, the X20 clearly surpasses the E90 in focusing range and image quality.

Night and Astro Photography

• ISO Performance: The X20 shines in low light up to ISO 3200, maintaining image clarity and color fidelity. Its maximum 30-second shutter and manual exposure allows astro and night photography experimentation.

• E90: Limited to ISO 3200 max but noise grows quickly; maximum shutter only 2 seconds limits night shooting flexibility.

Neither is a specialized astro camera, but the X20 offers more opportunities for creative night photography.

Video Capabilities

• Fujifilm X20: Records Full HD 1080p at 60fps with H.264 compression. Lacks microphone or headphone ports, but image stabilization helps video steadiness. No 4K or high bitrate options, but video quality is respectable for casual use.

• Pentax E90: Maximum 720p at 15fps or lower resolution at 30fps in Motion JPEG format, resulting in blockier footage unsuitable for serious video.

For casual video, the X20 is clearly the better choice.

Professional Work and Workflow Integration

Neither camera is designed for professional studios or high-end commercial work, yet:

• Fujifilm X20: Supports RAW capture, essential for advanced post-processing and tuning. USB 2.0 and HDMI out facilitate tethering and preview on external monitors.

• Pentax E90: No RAW support, limiting editing potential. Lacks HDMI output.

If you require RAW files and more flexible workflow, the X20 is essential.

Battery Life and Storage Practicalities

• Fujifilm X20: Uses proprietary NP-50 batteries rated for approximately 270 shots. USB 2.0 for data transfer and HDMI output for viewing.

• Pentax E90: Runs on two AA batteries - photo count per set not officially rated but typically around 200 shots in my experience. Storage options include SD cards plus limited internal memory.

Carry spares either way, but AA batteries of the E90 have the advantage of universal availability, while Fuji NP-50 may require specialized spares.

Connectivity Features

Neither model offers wireless connectivity like Wi-Fi, Bluetooth, or NFC, a limitation in today’s terms. Fuji’s X20 has HDMI output; Pentax does not.

Price-to-Performance Ratio and Market Positioning

Fujifilm X20 retailed near $500 at launch, reflecting its enthusiast-grade features and superior image quality.

Pentax E90 was a budget option around $100, targeting casual users needing a basic camera.
