Top view handling confirms the Efina’s minimalist approach versus the QX100’s reliance on a smartphone. The QX100’s lack of built-in controls means you must navigate settings via your phone app, potentially a barrier in dynamic shooting environments unless you’re comfortable with digital interfaces.

Sensor Technology and Image Quality: Why Size Still Matters

Core to every camera’s imaging DNA is the sensor. Let’s look at what these cameras bring to the table:

Sensor Feature Pentax Efina Sony QX100
Sensor Type 1/2.3" CCD 1" BSI-CMOS
Sensor Dimensions 6.17 x 4.55 mm (28.07 mm²) 13.2 x 8.8 mm (116.16 mm²)
Resolution 14 MP 20 MP
Max Native ISO 1600 6400
Optical Low Pass Filter Yes Yes

Pentax Efina vs Sony QX100 sensor size comparison

From a technical viewpoint, the Sony QX100 clearly boasts a much larger sensor. The 1-inch BSI-CMOS sensor dramatically outperforms the Efina’s smaller 1/2.3-inch CCD in light gathering capability and noise control. The back-illuminated (BSI) CMOS design of the QX100 enhances low-light performance and dynamic range, critical factors in difficult lighting conditions.

In practice, the QX100 produces images with richer tonal range, less grain at high ISO, and superior color depth. For landscape, night, and portrait photography where image quality is essential, the larger sensor size makes a notable difference - you will see finer detail and cleaner shadows. The Efina’s sensor restriction limits sharpness and introduces more noise at ISO 800-1600, especially in low light.

The Efina is more suited to casual shooting and daylight scenarios, while the QX100 can be confidently used in more demanding situations thanks to its sensitivity and resolution.

Display and Interface: Where You See Matters

Handling and user control flow from the display system offered:

Display Feature Pentax Efina Sony QX100
Screen Size 2.5” Fixed QVGA TFT LCD None (relies on smartphone)
Touchscreen No Yes (on smartphone)
Selfie-friendly No No

Pentax Efina vs Sony QX100 Screen and Viewfinder comparison

The Pentax Efina’s fixed 2.5-inch display delivers a modest, low-resolution viewfinder equivalent. Its limited resolution (230k dots) and the absence of touch controls can make image review and menu navigation feel outdated. Since it’s non-articulated and small, composing complex scenes or reviewing fine details isn’t ideal.

Sony’s QX100 design philosophy inverts this: the camera module itself lacks a screen and is designed to pair wirelessly with your smartphone, effectively outsourcing the display and control interface to your mobile device’s superior touchscreen and higher resolution. This adds versatility but introduces a dependency on a compatible smartphone.

This arrangement makes the QX100 more appealing for tech-savvy users comfortable with smartphone tethering. However, in situations with weak Wi-Fi or drained phone batteries, this can become a drawback.

Photography Disciplines: How Do These Cameras Perform?

Both cameras may be ultracompact, but their intended use cases and technical capabilities vary drastically. Here’s a breakdown by photography type.

Portrait Photography

Pentax Efina:

  • Skin tones are fair under good lighting but can appear flat due to limited dynamic range.
  • Fixed f/3.5 - 6.3 lens aperture restricts shallow depth-of-field effects and creamy bokeh.
  • Face detection autofocus aids with focusing on subjects but lacks advanced eye AF or tracking.

Sony QX100:

  • Wide f/1.8 aperture at 28mm equivalent allows for beautifully blurred backgrounds and sharp subject separation.
  • Larger sensor enables better skin tone gradation, color accuracy, and appealing highlight roll-off.
  • Contrast-detection AF with face detection is effective, although real-time eye tracking isn't supported.

Verdict: For portraits featuring creamy bokeh and nuanced colors, QX100 stands out.

Landscape Photography

Here, resolution, dynamic range, and ruggedness come into play.

  • The Efina’s 14 MP CCD and limited ISO range may struggle with shadow details in high-contrast scenes.
  • QX100 with 20 MP, larger sensor, and higher max ISO captures finer detail and wider tonal spread.
  • Both lack weather sealing and rugged bodies, limiting outdoor harsh condition use.

The QX100 is definitively better for landscape enthusiasts who value image quality over camera toughness.

Wildlife Photography

Critical elements are autofocus speed, telephoto reach, and burst shooting.

Feature Pentax Efina Sony QX100
Focal Length (35mm eq.) 26-130mm 28-100mm
Max Aperture f/3.5-6.3 f/1.8-4.9
AF System Contrast detection, center-weighted Contrast detection
Continuous Shooting None None

Neither camera is built for fast-action wildlife, due to lack of continuous autofocus and burst mode. The Efina’s slightly longer zoom helps, but lens speed and focus lag reduce likelihood of capturing sharp wildlife images. The QX100’s brighter lens helps in low light but with manual focus needed for fast subjects, it’s limited.

Sports Photography

Sports demand rapid frame rates, locking focus, and robust controls.

Neither camera supports continuous autofocus or continuous shooting; both have shutter speeds maxing out at 1/1400 (Efina) and 1/2000 (QX100), which is marginally better on the Sony.

Both fall short for sports purposes, particularly for professional sports photographers who rely on rapid and accurate tracking. They serve more as casual sport event shooters.

Street Photography

Street photography favors discretion, low-light performance, and portability.

Criteria Pentax Efina Sony QX100
Discreteness Very discreet due to tiny size More noticeable due to lens form
Low Light Limited ISO (max 1600), digital IS ISO up to 6400, optical IS
Portability Ultra-light and slim Lens module design requires phone

For quick environmental portraits and candid moments, the Efina is very pocketable and ready to shoot. The QX100’s capability to leverage a smartphone makes for creative shooting angles although it requires a moment to connect.

Macro Photography

Close-up capabilities depend on focusing range and lens sharpness.

Feature Pentax Efina Sony QX100
Macro Focus Range 20 cm 5 cm
Stabilization Digital Optical

The QX100’s ability to focus as close as 5 cm paired with optical image stabilization gives it a clear advantage for detailed macro photography. The Efina’s longer minimum focus distance and digital stabilization make close-ups less sharp.

Night and Astro Photography

High ISO and exposure flexibility are essential.

  • The Efina’s max ISO 1600 restricts its effectiveness in darker conditions.
  • QX100’s ISO ceiling of 6400 and ability to shoot longer exposures up to 1/4s (min shutter 4s max) facilitates better low-light capture.
  • Neither supports built-in intervalometers or astro-specific modes, but QX100’s better sensor and lens can produce respectable night shots.

Video Capabilities

Battery life is about 200 shots for both; the Sony benefits from external charging options via smartphone, yet phone battery drain is a concern.

Professional Use and Workflow Integration

Both cameras lack raw image format and advanced customization, limiting their integration into professional workflows. No tethered shooting or external flash compatibility restricts studio or event use.

Sony’s ability to connect wirelessly to smartphones opens some creative possibilities but doesn’t substitute tethered pro rig features.

Autofocus Performance Deep Dive

Both cameras employ contrast-detection autofocus, customary for compact types in 2013.

  • Pentax Efina: Face-detection is present but limited to center-weighted area. No continuous AF. Focus speed is modest at best, often hunting in low light.
  • Sony QX100: Supports face detection and touch autofocus via smartphone interface, potentially faster but not designed for continuous AF.

Neither competes with modern phase-detection systems or hybrid AF but the QX100’s higher-performing sensor and software integration give it an edge in speed and accuracy for static subjects.

Lens and Compatibility

Neither model allows lens interchange:

  • Efina’s lens: 26-130mm equivalent zoom at f/3.5-6.3 aperture; basic but versatile for casual use.
  • QX100’s lens: 28-100mm f/1.8-4.9, faster aperture ideal for low light and artistic depth-of-field.

The QX100’s lens speed and image quality are in line with higher-end compact cameras, making it capable for enthusiasts. Efina’s lens is suitable for snapshots but reveals softness at telephoto and corners.

Stabilization and Image Sharpness

  • Efina uses digital image stabilization, which can reduce image resolution and increase artifacts.
