Fujifilm S9800 vs. Pentax X70: A Deep Dive into Two Small Sensor Superzoom Contenders

When it comes to choosing a superzoom camera that balances extensive focal reach with manageable size and versatile features, the market is filled with options. Among these, the Fujifilm S9800 and the Pentax X70 stand out as SLR-style bridge cameras featuring small 1/2.3-inch sensors and fixed superzoom lenses. Although these two models cater to similar entry-level segments from around the mid-2000s to 2010s, a closer examination reveals distinct design philosophies, technological choices, and practical performance stories.

Having spent dozens of hours, spanning both lab-controlled test environments and real-world shooting scenarios, comparing hundreds of camera models over the years, I’m ready to walk you through the detailed strengths, tradeoffs, and ideal use cases for each camera. Whether you’re a casual traveler, a budding wildlife enthusiast, or simply seeking an affordable superzoom, this guide will help you understand what to expect out of these two cameras - and where one distinctly outperforms the other.

Form Factor and Handling: Sculpted for Comfort or Compact Convenience?

At first glance, both cameras embrace the “bridge” style - aiming for the DSLR feel with an integrated zoom lens. Yet the Fujifilm S9800 feels more substantial in the hand, tipping the scales at roughly 670 grams compared to the Pentax X70’s lighter 410 grams. Physically, the S9800 is also bulkier at 123x87x116 mm versus the X70’s 110x83x90 mm.

This extra heft translates into a more pronounced grip on the S9800, enhancing stability during longer telephoto shooting sessions, especially handheld at the extreme 1200mm equivalent focal length. The ergonomics favor photographers who prioritize grip security over pocketability.

On the other hand, the Pentax X70’s compact frame and reduced weight make it ideal for travel and street shooters who want a discreet, easy-to-carry superzoom. While it may feel lighter and less locked in your hand, it’s a tradeoff that makes it easier to slip into a bag or large coat pocket for spontaneous shooting.

Both cameras offer fixed, non-articulating LCDs with no touch capabilities - more on those screens shortly - but the larger chassis of the Fujifilm provides more room for tactile control buttons and dials, making manual adjustments more intuitive in the field.

In short: If you want a camera that feels more resolute and substantial, the S9800’s design suits you. If portability is a priority, the Pentax X70 has the edge.

Layout and Control Philosophy: Intuitive Access vs. Minimalism

Moving beyond just size, how the controls are laid out plays a surprisingly important role in daily usability. The Fujifilm S9800 adopts a traditional DSLR-like top panel with dedicated dials for shutter speed and aperture, a mode dial, and clearly marked buttons for exposure compensation and flash control - as clearly visible in the image below.

The Pentax X70, while still SLR-like, utilizes a stripped-down approach. It forgoes extensive manual dials, reflecting its era’s more limited focus on beginner-friendly auto modes with aperture and shutter speed control accessible via menus or buttons. Real manual control is possible but requires a bit more button mashing and muscle memory.

In practical experience, the S9800’s design distinctly accelerates workflow during dynamic situations such as wildlife, sports, and macro photography where quick manual tweaks are crucial. The dedicated exposure compensation also enables finer creative control on the fly.

So, if you regularly shoot in manual or semi-manual modes and dislike fiddling with menus, Fujifilm’s implementation will feel more professional and less frustrating in practice. The Pentax X70, however, may be friendlier to pure point-and-shoot users focused on casual settings.

Sensor and Image Quality: The Heart of the Matter

Both cameras house 1/2.3-inch sensors - a tiny footprint compared to APS-C and full-frame - but they diverge in sensor technology and resolution, which dramatically affects image character and quality.

The Fujifilm S9800 uses a CMOS sensor with a resolution of 16 megapixels, whereas the Pentax X70 features a 12 MP CCD sensor. Generally, CMOS sensors excel with faster readout speeds, improved high ISO performance, and better dynamic range, while CCDs tend to suffer in low light and exhibit slower operation.

Throughout extensive side-by-side testing, the S9800 consistently delivered slightly sharper images with cleaner noise profiles beyond ISO 800, thanks in part to CMOS technology. It also allowed extended shutter speeds down to 8 seconds, enabling more flexible exposure times for creative or night photography.

Pentax’s CCD, while capable of pleasing color reproduction at base ISO, showed notable noise and color shifts starting above ISO 400. The maximum shutter speed tops out at 1/4000s, beneficial for bright light but less versatile overall.

For landscape and travel photography where detail and clean shadows matter, the S9800’s larger 16 MP sensor has a meaningful advantage, especially considering the 50x zoom range that benefits from more pixels for cropping and printing. Conversely, if you primarily shoot outdoors in bright daylight or intend small web sharing, the Pentax’s 12 MP CCD still delivers satisfying quality with classic CCD color signature.

Display and Viewfinder: How You Frame Photos

Both cameras feature fixed (non-articulating) LCDs. The Fujifilm S9800’s 3-inch LCD offers 460K-dot resolution, providing a brighter and more detailed viewing experience than the Pentax’s 2.7-inch, 230K-dot screen - a distinction clearly visible in direct comparison.

Adding to the framing toolkit, the Fujifilm S9800 includes a 920K-dot electronic viewfinder (EVF) with near 97% coverage, while the Pentax X70 lacks an EVF entirely - relying solely on the rear LCD for composing shots.

For photographers shooting in bright outdoor environments, this EVF is a substantial usability advantage, especially when using super telephoto focal lengths where camera shake risks increase. It also speeds up workflow in action photography where quick eye-level framing matters.

Pentax X70 users may find themselves battling glare and reflections on the smaller LCD in strong sunlight, limiting compositional flexibility outdoors.

Autofocus and Shooting Speed: Speed and Tracking in Action

Autofocus (AF) system design and speed are often the deciding factors for wildlife and sports shooters. Here’s where the two cameras start to really split.

The Fujifilm S9800 employs a contrast-detection AF with face detection and multi-area selection. It supports continuous AF and tracking modes, allowing it to lock onto moving subjects reasonably well. Four driving modes include single shot and burst shooting up to 10 frames per second.

The Pentax X70 relies on a hybrid system utilizing 9 phase-detection points combined with contrast detection, but limited to single AF without continuous tracking, and it lacks burst shooting capabilities.

Testing in controlled environments confirms these specs: the S9800’s autofocus is undoubtedly faster in continuous tracking and better at maintaining focus on erratic subjects. This makes it much more suitable for wildlife and sports, where moments are fleeting.

The X70’s AF is a bit more sluggish and less reliable for moving subjects - better suited for static or slow-moving scenarios such as landscape or street photography.

Built Quality and Weather Sealing: Durability Under the Lens

Neither model offers weather sealing, dustproofing, or rugged environmental resistance - understandable given their budget bridge category. However, construction quality feels durable enough for casual field use.

The Fujifilm’s larger frame and body materials lend a reassuring heft but do not make it inherently water- or shockproof. The Pentax’s lighter plastic body is solid, but will succumb to harsher treatment faster.

If you plan expeditions in rainy climates or dusty outdoors, investing in protective covers or bags is essential regardless of which camera you choose.

Lens Systems Compared: Zoom Reach and Optical Qualities

Since both cameras are fixed-lens superzooms, lens specs deserve close scrutiny.

• Fujifilm S9800: 24-1200mm (50x zoom equivalent), aperture f/2.9-6.5
• Pentax X70: 26-624mm (24x zoom equivalent), aperture f/2.8-5.0

Clearly, Fujifilm offers dramatically longer reach with 1200mm, nearly doubling Pentax’s max telephoto focal length. This opens up photographic opportunities from distant wildlife to tight action shots.

Fujifilm’s lens starts slightly slower wide at f/2.9 vs. Pentax’s f/2.8 but dives into a narrower aperture at full zoom. Both lenses include optical image stabilization, though the Pentax relies on sensor-shift stabilization whereas the Fujifilm uses optical stabilization in the lens assembly.

Sharpening tests reveal the Fujifilm lens is sharp pier to pier at wide and middle focal lengths but softens at 1200mm - a common limitation in superzooms. The Pentax lens maintains decent sharpness up to its max telephoto though the narrower zoom range limits framing flexibility.

Macro focusing distances favor the S9800 at 7cm, enabling closer detail capture than the X70’s 10cm minimum. This slight edge benefits macro and close-up enthusiasts.

Battery Life and Storage Efficiency

The Fujifilm S9800 uses four AA batteries - an accessible choice allowing quick field swaps and popular rechargeable compatibility. It boasts approximately 300 shots per charge, which is modest but workable.

Pentax’s X70 uses a proprietary rechargeable D-LI92 battery but lacks official battery life specs. Users have reported moderate endurance but typically fewer shots per charge than Fujifilm’s setup - worth keeping spares or power banks handy.

Both cameras accept SD/SDHC/SDXC cards and feature single card slots with internal memory backup.

Connectivity and Additional Features

Neither the Fujifilm S9800 nor Pentax X70 includes wireless features such as Wi-Fi, Bluetooth, or GPS. For photographers wanting instant transfer, remote control, or geotagging, this absence is a significant limitation given contemporary expectations.

Video-wise, the S9800 records Full HD 1080p at 60i, 720p at 60p, and VGA at 30fps using the more efficient H.264 codec. The Pentax X70 maxes at 720p 30fps using outdated Motion JPEG, resulting in larger file sizes and lower quality.

The S9800 supports HDMI output (absent on X70) offering easy connection to external monitors - a boon for videographers.

No microphone or headphone jacks on either device limit advanced audio recording.
