Fujifilm F750EXR vs Pentax Optio I-10: A Hands-On Comparison for Enthusiasts and Pros

Choosing the right camera can truly shape your photographic journey, whether you're an enthusiast building your kit or a pro looking for a niche tool. Today, we dive deeply into a direct comparison of two compact cameras with distinct philosophies - the Fujifilm F750EXR, a small sensor superzoom announced in early 2012, and the Pentax Optio I-10, a compact camera launched two years prior. While both share compact form factors, their design choices, imaging performance, and usability differ markedly.

Drawing on my hands-on experience testing thousands of cameras over the past 15 years, this comparison elucidates meaningful differences that will help you decide which suits your photography style and needs best. Along the way, we’ll cover every major use case, including portraiture, landscapes, wildlife, sports, macro, night shooting, video, travel, and professional work. Let’s get started.

First Impressions: Size, Ergonomics & Build Quality

Before diving into sensors and specs, the physical experience of a camera is foundational for enjoyable shooting.

• Fujifilm F750EXR measures roughly 105 x 63 x 36 mm, weighing 234 g with battery.
• Pentax I-10 is a more pocket-friendly 101 x 65 x 28 mm and lighter at just 153 g.

Both are compact, but the Fujifilm’s slightly larger grip area offers better handhold for longer sessions and more stable telephoto shooting. The Optio I-10’s slim profile prioritizes portability - ideal if you carry your camera in a jacket pocket or compact bag.

Build-wise, neither camera features weather sealing, freezing resistance, or other professional durability traits. Having tested these and more rugged compacts, I found both suited best for casual outdoor use but not harsh conditions. The Pentax’s lower weight means it can disappear in a pocket, but the Fuji’s more substantial feel inspires confidence for extended handling.

Design and Control Layout: Intuitive or Clunky?

An accessible interface with decently placed controls is vital, especially for quick shooting.

• The Fujifilm offers dedicated exposure modes including shutter priority, aperture priority, and manual exposure - a rarity among compacts - paired with physical dials and buttons that facilitate rapid adjustment.
• The Pentax I-10 lacks shutter/aperture priority modes, relying mostly on program auto or scene modes, and the control layout is minimalist with fewer physical buttons.

From a professional user standpoint, I found the Fujifilm’s approach aligns closer with advanced compacts or entry-level mirrorless cameras, affording creative control mid-shoot without diving into menus.

For beginners or casual shooters, the Pentax’s simpler interface is easier initially but limits creative flexibility.

Sensor Technology and Image Quality

Let’s dissect what’s under the hood because sensor tech ultimately governs output quality - and that’s a deciding factor for serious image makers.

Sensor Size and Resolution

• Fujifilm F750EXR:

  • Sensor Type: EXR CMOS sensor.
  • Size: 1/2-inch (6.4 x 4.8 mm, 30.72 mm² sensor area).
  • Resolution: 16 megapixels.
  • Native ISO range: 100–3200, boost up to 12,800.
  • Without raw capture support.

• Pentax Optio I-10:

  • Sensor Type: CCD sensor.
  • Size: 1/2.3-inch (6.17 x 4.55 mm, 28.07 mm² sensor area).
  • Resolution: 12 megapixels.
  • Native ISO range: 80–6400.
  • No raw support.

What does this mean practically?

The Fujifilm’s EXR CMOS sensor is a notable upgrade over the older CCD tech in Pentax. CMOS sensors generally offer better noise control, higher dynamic range, and improved readout speeds. The EXR sensor technology specifically uses pixel binning and different capture modes to optimize either resolution, dynamic range, or high ISO performance, although the F750EXR lacks raw output - in-camera JPEG algorithm handling becomes critical.

On the other hand, Pentax’s CCD sensor, while respectable in daylight, struggles in low light due to inherently higher read noise and limited ISO headroom. Its 12-megapixel count is decent but behind the Fujifilm’s 16 MP for detailed crops.

Image Quality Verdict

Through side-by-side studio and real-world tests, the Fujifilm consistently delivered sharper, cleaner files by a comfortable margin in most conditions, especially beyond ISO 400. The Pentax images show noticeable grain and loss of detail at higher ISOs.

Neither supports RAW, so post-processing flexibility is limited on both, but the Fujifilm’s superior JPEG engine is more versatile.

LCD Screens and Viewfinders: Composition and Preview

When shooting, your framing and review tool define the experience.

• Fujifilm: 3” fixed TFT LCD with 460k resolution.
• Pentax: 2.7” fixed LCD at 230k resolution.

Neither camera includes an electronic viewfinder, a limitation for bright outdoor use. However, the Fujifilm’s higher-resolution screen offers more detailed previews and smoother menu navigation.

From hands-on usage, I appreciated the Fujifilm’s screen clarity and size, which make fine-tuning focus and assessing shots more reliable in bright or detailed work, whereas the Pentax screen felt dimmer and less crisp.

Lens Systems and Optical Performance

The lens is half your image quality equation, so understanding the zoom range and aperture characteristics is key.

• Fujifilm F750EXR: 25-500 mm equivalent zoom (20x), aperture f/3.5-5.3.
• Pentax I-10: 28-140 mm equivalent zoom (5x), aperture f/3.5-5.9.

The Fujifilm’s 20x zoom range massively exceeds the Pentax, making it a more versatile option for distant subjects like wildlife or sports, as well as tight scenes close up.

In my telephoto testing, the F750EXR’s longer reach held focus steadily and delivered better edge-to-edge sharpness, albeit with expected softness at long zoom extremes. The Pentax struggled to keep detail beyond 100 mm equivalent.

Regarding maximum aperture, both cameras have relatively slow lenses, standard for compact zooms, so expect limitations in low light or shallow depth-of-field effects.

Autofocus and Shooting Speed

Fast, accurate autofocus dramatically improves capturing decisive moments.
