Fujifilm F500 EXR vs Pentax X70: A Detailed Comparative Exploration of Small Sensor Superzoom Cameras

When diving into the niche of small sensor superzoom cameras, the landscape is littered with models that promise versatility but often fall short in one area or another. Today, I want to focus tightly on two contenders that have gathered a modest but loyal following: the Fujifilm F500 EXR, released in early 2011, and the Pentax X70, a bridge-type camera launched in 2009. Both occupy a similar category - compact superzooms - but differ in design philosophy, technical specifics, and real-world user experience.

Having spent considerable time testing each across multiple photography genres, I’m excited to walk you through a detailed head-to-head. In doing so, I'll blend hands-on impressions, sensor and autofocus technology analysis, ergonomics, and usability insights. Let’s kick things off by looking at their physical characteristics and how that impacts handling.

Size, Ergonomics & Physical Design: Compact Convenience vs Bridge Presence

The Fujifilm F500 EXR is a compact-bodied superzoom weighing only 215g, dimensions snug at 104x63x33mm. This size lends itself to easy slip-into-pocket portability, which is a blessing when you want something capable but unobtrusive on city streets or casual hikes.

Versus the Fujifilm, the Pentax X70 is more of a bridge camera with an SLR-like stance, weighing nearly twice as much at 410g and measuring 110x83x90mm. Its deeper grip and larger body suggest more robustness and grip confidence, but it’s undeniably less pocketable - more of something you carry in a bag or hang around your neck deliberately.

Looking at that side-by-side gives a clear picture: size and heft naturally influence how you shoot. The X70's bigger body makes it feel more like a traditional DSLR substitute, with a mechanical manual focus ring handy for precise control - a feature the F500 EXR surprisingly lacks.

However, the EXR's slim profile suits travel and street photographers valuing discretion, while the X70 cooks up a bridge-camera vibe geared to enthusiasts who want manual control plus extended zoom without jumping to a DSLR.

Control Layout and Top-View Design: Where Usability Meets Intuition

Moving from size to controls, the top panel comparison reveals immediately divergent design philosophies.

The Fujifilm F500 EXR keeps things minimalist: straightforward mode dials, shutter button, and zoom rocker with clearly marked exposure modes (shutter priority, aperture priority, manual among them). This ease of use is intentional, aiming at casual enthusiasts who want just enough manual overrides without fuss.

In contrast, the Pentax X70, with its bulkier form factor, sacrifices simplicity for versatility: dedicated dials and a true manual focus ring offer tactile feedback and precision. The presence of an electronic viewfinder (EVF) adds another layer of shooting confidence, useful in bright light or for those preferring eye-level framing.

The EXR’s lack of EVF means relying exclusively on its 3-inch LCD, whereas the X70’s EVF plus a smaller 2.7-inch LCD provides dual framing options. For photographers shooting under the sun or tracking fast-moving subjects, this difference matters.

Sensor Comparisons and Image Quality: Small Sensors, Big Differences

Both cameras use small sensors - 1/2" for the F500 EXR and 1/2.3" for the X70 - but digging deeper into sensor technology reveals meaningful distinctions.

The Fujifilm F500 EXR employs an EXR CMOS sensor with a resolution of 16 megapixels and a size of roughly 6.4mm x 4.8mm (area: 30.72 mm²). EXR technology was Fuji’s innovative attempt to optimize sensor performance dynamically - enhancing dynamic range, improving noise control, or maximizing resolution depending on the shooting mode. The CMOS sensor also generally affords faster readouts and better low-light characteristics.

Pentax's X70 uses a traditional CCD sensor at 12 megapixels, sized slightly smaller (6.17mm x 4.55mm; 28.07 mm²). While CCDs historically excelled in color depth and detail rendition, they lag CMOS sensors in speed and high-ISO noise management.

Results? In well-lit conditions, both deliver decent image quality, but the Fujifilm edges out with higher resolution and generally better high-ISO performance (up to ISO 3200 native, expandable to 12800), thanks to its sensor and EXR processing. The Pentax’s max native ISO is 6400 but with arguably more noise due to CCD architecture and older processing tech.

This sensor advantage translates directly to disciplines like landscape and portrait where dynamic range and color fidelity matter. However, the 16MP resolution on the EXR is a benefit for cropping or large prints, while the X70’s 12MP remains serviceable.

Worth noting too: neither camera supports RAW output, which will disappoint photographers wanting maximum post-processing latitude.

LCD Screens and Live View Experience: The Window to Your Shot

The shooting experience depends largely on the LCD displays on these small all-in-one machines.

The Fujifilm F500 EXR’s screen is a 3-inch fixed TFT touchscreen with 460K-dot resolution - crisp and bright for reviewing shots or composing in live view. Though the EXR lacks touch capabilities, its higher resolution provides clearer previews.

The Pentax X70’s screen is slightly smaller - at 2.7 inches and 230K-dot resolution - making it less sharp, though with EVF presence, Pentax expects users to rely on eye-level framing more.

For those accustomed to framing on the LCD, the Fujifilm offers a better experience. It shines particularly in street and travel scenarios where quick framing adjustments on the fly make a difference.

Autofocus Systems: Speed vs Precision in Fast-Moving Situations

Autofocus is a realm where superzoom cameras often struggle, but understanding the tech helps set expectations.

The Fujifilm F500 EXR uses a contrast-detection autofocus system, with continuous, single, tracking, and center-only modes. Although it lacks phase-detection AF, a boon for speed and accuracy, the EXR's advanced contrast-AF manages reasonable performance in well-lit contexts.

Pentax’s X70 uniquely incorporates a phase-detection AF system (albeit limited to 9 focus points), which theoretically offers faster, more reliable autofocus - a feature rare in compact bridge cams of its generation. However, Pentax’s autofocus only works in single AF mode and lacks continuous AF capabilities, somewhat undermining practical speed benefits for sports or wildlife tracking.

In field tests, the X70’s autofocus felt snappier in static or slower scenes but lagged in continuous tracking needed for fast action. Meanwhile, Fujifilm’s EXR system, while slower in burst autofocus, performed decently with continuous AF enabled.

Neither camera offers face detection or animal eye-AF, which are game-changing features in modern systems.

Burst Shooting and Frame Rates: Catching the Critical Moment

Neither camera aims primarily at high-speed shooting, but careful evaluation remains crucial for sports or wildlife.

Fujifilm’s continuous shooting rate of 3.0 fps is modest yet usable for casual action sequences, while the Pentax does not specify burst speed clearly, and testing reveals quite sluggish performance.

This, paired with the faster shutter speed range of the Pentax (max 1/4000s vs. Fujifilm’s 1/2000s), somewhat balances the scales. Faster shutter speeds are key to freezing sharper images of swift subjects in bright conditions.

For serious sports photography, neither camera is ideal, but the Fujifilm edges out simply because burst shooting can be exploited somewhat, even if limited.

Zoom Range and Lens Performance: Flexibility vs Maximum Reach

Superzoom cameras live or die by their lenses.

• Fujifilm F500 EXR: 24-360mm (15x optical zoom), aperture f/3.5-5.3
• Pentax X70: 26-624mm (24x optical zoom), aperture f/2.8-5.0

Clearly, the Pentax boasts nearly double the maximum focal length, allowing photographers to peer at far-away subjects better - a key advantage in wildlife or surveillance.

The Pentax also opens wider at the wide end (f/2.8 vs. Fujifilm’s f/3.5), aiding low-light capture and enabling slightly shallower depth of field, beneficial for portraits or low-light indoors.

However, longer telephoto reach often means more compromise on image stabilization and sharpness, especially on small sensors. The Fujifilm’s optical path and sensor-shift stabilization (present in both cameras) ensure reasonable sharpness up to 360mm equivalent.

Macro capabilities: Fujifilm focuses as close as 5cm, versus Pentax’s minimum macro distance of 10cm - making the Fujifilm a subtly better choice for close-up shots.

Image Stabilization and Low-Light Handling: Stabilize But Don’t Overexpect

Both cameras use sensor-shift image stabilization, which physically shifts the sensor to counteract camera shake. This is notable in small sensor compacts but limited in effectiveness at longer zooms.

In field conditions, the F500 EXR’s stabilization feels slightly more effective, likely benefiting from its newer EXR processor and sensor combo to boost usable shutter speeds.

Moreover, ISO handling favors the Fujifilm's CMOS sensor with decent noise control at ISO 800-1600; ISO 3200 is marginal but usable. Pentax’s CCD struggles with noise at higher ISOs, with noticeably grainier images beyond ISO 800.

This difference makes the Fujifilm a better choice for indoor, low-light, or night photography, even if neither camera pushes the boundaries here.

Video Capabilities: Beyond Stills with Limited Specs

Looking at video:

• Fujifilm F500 EXR records full HD 1080p at 30fps in MPEG-4 format.
• Pentax X70 maxes out at 720p at 30fps, using Motion JPEG.

The EXR clearly wins on resolution and video codec efficiency, making it more suitable for casual video projects. However, neither camera includes microphone or headphone ports, limiting audio control.

Neither offers advanced video features like 4K, slow motion, or sophisticated stabilization beyond sensor-shift steadiness for stills.

Battery Life and Storage: Practicality in the Field

Neither camera specifies exact battery life in shots per charge, but the Fujifilm F500 EXR uses the NP-50 battery, which is light and generally rated around 220 shots per charge - a fairly standard figure for compacts of its era.

The Pentax X70’s D-LI92 battery is larger but also powers the EVF, which can drain power faster. Real-world usage suggests about 200-250 shots per battery cycle. Both cameras use a single SD/SDHC storage slot, with the Pentax optionally sporting some internal storage (a minor convenience).

Connectivity and Extras: Basic to Minimal

Neither the Fujifilm nor the Pentax cameras feature wireless connectivity, Bluetooth, or NFC, which limits image sharing or remote control capabilities right out of the box.

The Fujifilm includes HDMI output for easy display connection, whereas the Pentax lacks this, making video review more cumbersome.

Sample Image Quality and Real-World Performance: The Proof in Pixels

In controlled tests and varied lighting, Fujifilm’s photos show sharper details, more accurate colors, and better handling of shadows and highlights due to the EXR sensor's capabilities. Landscapes reveal richer color gradations, and portraits benefit from smoother skin tones and appealing bokeh given the sensor and lens combo.

Pentax images demonstrate decent sharpness at base ISO and moderate zoom but fall short in dynamic range and exhibit more noise in dim settings. The extended zoom range is a nice tool for distant wildlife shots, though image softness at full telephoto is noticeable without a tripod.

How They Score on Overall Performance and Genre Suitability

Comprehensive testing metrics give the Fujifilm a slight edge overall, balancing image quality, autofocus performance, and usability. The Pentax rates well on zoom reach but loses points on sensor performance and user interface.

Drilling deeper into specific photography types:

• Portraits: Fujifilm’s better color fidelity and higher resolution win; manual focus on Pentax helps but can be fiddly.
• Landscape: Fujifilm again favored for dynamic range; Pentax zoom superfluous here.
• Wildlife: Pentax’s zoom advantage excels; Fujifilm autofocus marginally slower.
• Sports: Neither are sport shooters; Fujifilm’s burst shooting supports casual action better.
• Street: Fujifilm’s smaller size and better LCD screen for framing edges out Pentax.
• Macro: Fujifilm’s closer focusing distance is a plus.
• Night/Astro: Fujifilm’s ISO prowess gives it the advantage.
• Video: Fujifilm delivers higher resolution and better codec.
• Travel: Fujifilm’s lighter body and versatility suit; Pentax’s bulk and zoom less practical.
• Professional work: Neither offers RAW or high-end reliability features; Fujifilm edges with manual exposure and better image quality.
