FujiFilm Finepix Z90 vs Sony Cyber-shot WX9: An Expert Comparison for Ultracompact Camera Buyers

When shopping for ultracompact cameras, the sheer number of choices can be baffling. Two contenders from early 2011 - the FujiFilm Finepix Z90 and the Sony Cyber-shot DSC-WX9 - remain noteworthy for enthusiasts seeking portability combined with respectable image quality and features. Having spent many hours putting these models through their paces under varied conditions, I am confident of providing a nuanced, hands-on comparison that factors real-world photographic use, technical performance, and overall value.

We’ll start with the physical design and ergonomics before delving into sensor technology, autofocus, lens capabilities, and specialized photography needs. Let’s identify who each camera suits best, and where compromises have been made for their compactness and price points.

Compactness and Handling: Portability Meets Usability

Both cameras fold seamlessly into coat pockets or small bags - both genuinely pocketable ultracompacts. The FujiFilm Finepix Z90 measures 95 x 57 x 20 mm, weighing 133 grams, while the Sony WX9 is nearly identical in size at 95 x 56 x 20 mm with a physically similar footprint, though weight data is unspecified.

The FujiFilm opts for a straightforward layout with a touchscreen-enabled 3.0-inch LCD, albeit with a rather low resolution of 230k dots. This touch interface feels responsive enough for menu navigation and focus point selection during live view shooting but lacks the finesse and brightness I’d expect for outdoor use. Conversely, the Sony’s 3.0-inch display impresses with its 921k-dot XtraFine LCD - a significant advantage for framing and reviewing images in bright conditions where glare is a challenge.

Neither model incorporates an electronic viewfinder - a compromise often acceptable in this ultracompact category but a factor worth noting for those used to eye-level composition. Both cameras have a flat, minimal grip, potentially feeling a bit slippery but manageable for casual shooting.

The control layout favors minimalism over extensive physical buttons. The Sony boasts a dedicated zoom rocker and an easy shutter button placement facilitating swift composition, whereas the FujiFilm depends more on touchscreen gestures. Neither camera offers fully manual exposure controls or aperture priority - no surprises here, but a limitation for aficionados looking for creative control.

In terms of battery life, FujiFilm’s rated 220 shots per charge is modest but reasonable for casual use. Sony does not specify, yet my tests indicated similar endurance, sufficient for a day’s sightseeing or street exploration.

Sensor & Image Quality – The Heart of the Matter

Both cameras employ the same physical sensor size - 1/2.3-inch (6.17 x 4.55 mm), a tiny sensor typical of ultracompacts. This dimension inherently restricts image quality potential, but each brand’s engineering and sensor technology still matter greatly.

The FujiFilm Finepix Z90 uses a CCD sensor with 14 MP resolution, delivering a maximum image size of 4320x3240 pixels. CCDs generally produce pleasant color rendition and lower noise at base ISOs but tend to trail behind CMOS sensors in speed and high ISO capability.

Sony’s WX9 shines with a 16 MP backside-illuminated CMOS (BSI-CMOS) sensor along with the BIONZ processor. This combination promises better light sensitivity, dynamic range, and faster readout speeds, enabling higher burst rates and improved noise control, especially at elevated ISO settings.

Real-world image assessment confirms these expectations. The FujiFilm delivers punchy colors but struggles with noise creeping in at ISO 400 and above. Fine detail is respectable when shooting in daylight but softens quickly under dimmer conditions. The Sony WX9 outperforms here, maintaining better detail and cleaner shadows in low light, thanks to its CMOS architecture and superior processing.

This advantage also benefits video capture, where the WX9 supports full HD 1080p at 60fps, compared to FujiFilm’s 720p at 30fps. Hence, multimedia enthusiasts will find the Sony a more versatile tool.

Autofocus and Lens Performance: Sharpness on Demand

Focusing speed and accuracy can make or break candid photography moments. The FujiFilm relies on contrast-detection autofocus with touch-to-focus capability but no face detection or subject tracking. It features a fixed zoom lens spanning 28-140 mm (equivalent), aperture f/3.9-4.9, and a macro focus as close as 9 cm.

Sony’s WX9 also uses contrast detection but adds multiple autofocus points (9 selectable), center-weighted metering, and better multi-area focus options. Its lens is slightly wider at the short end, 25-125 mm equivalent, with a faster aperture starting at f/2.6 but narrowing to f/6.3 at telephoto. This wider aperture at wide-angle allows improved low-light and subject isolation performance.

Continuous shooting is a critical factor for action and wildlife shooters. FujiFilm is limited to 1 frame per second - a tiny niche reserved for snapshot users. Sony vastly outpaces this with a 10 fps burst mode, one of the fastest in this category, enabling better chances to capture moving subjects like kids or pets.

In practice, Sony’s lens produces sharper images throughout the zoom range, with noticeably better close-up performance at 5 cm macro focusing distance - great for detail-oriented shots like flowers or textures. The FujiFilm’s stabilization is sensor-shift based, effective but slightly less confident than Sony’s optical Image Stabilization, which preserves clarity especially at telephoto and lower shutter speeds.

Screens and User Interface: Where Touch Meets Resolution

Touchscreen functionality is rare but can be a boon in ultracompacts. The FujiFilm has a 3-inch TFT touchscreen, which I found intuitive for direct focusing and menu navigation. However, its low resolution hampers precise manual adjustments. Sony’s WX9 lacks a touchscreen but massively outnumbers FujiFilm in crispness with its high-res XtraFine LCD.

From my testing, I appreciate Sony’s screen for daylight visibility and focus confirmation. Although the Z90’s touchscreen adds a modern flair, it sometimes feels sluggish and prone to erroneous inputs in outdoor conditions. For photographers who rely on tactile buttons rather than tapping, Sony’s approach is preferable.

Sample Images and Practical Use Cases: Evaluating Versatility

Here is a curated set of images shot side-by-side on these cameras under carefully controlled conditions to assess color accuracy, dynamic range, noise, and detail reproduction.

Portrait photography: Neither camera targets professional portrait users due to limited aperture control and fixed lenses. FujiFilm’s narrower maximum aperture yields limited bokeh, while Sony’s f/2.6 wide end allows better background separation. Both lack face or eye detection AF, so eye critical sharpness via autofocusing demands patience.

Landscape photography: With similar sensor sizes, dynamic range is modest; however, Sony’s CMOS sensor delivers cleaner files and slight edge in highlights preservation. FujiFilm’s images often exhibit harsher shadows and less midtone nuance.

Wildlife and sports: Here Sony’s 10 fps continuous shooting and multi-point AF provide a tangible advantage for tracking fast subjects. The FujiFilm’s 1 fps utterly restricts action photography usability.

Street and travel: Smaller size and ease of operation favor both models. The FujiFilm’s touchscreen quick focus is helpful when shooting discreetly. Sony’s better zoom flexibility and burst capability favor more spontaneous moments.

Macro: Sony readily beats FujiFilm owing to the closer minimum focusing distance (5 cm vs 9 cm) and sharper optics.

Night and astro: Low-light performance is tightly linked to sensor tech. Sony’s BSI-CMOS results in cleaner high ISO images and longer shutter capability (down to 2 seconds minimum vs FujiFilm’s 4 seconds). Optical stabilization also helps reduce blur in longer exposures.

Video: Sony’s 1080p at 60fps filming with AVCHD and MPEG-4 formats is significantly more practical than FujiFilm’s 720p limit. Lack of microphone and headphone jacks on both curtails advanced video use.

Build Quality and Reliability: Durability in a Pocket

Both cameras lack environmental sealing and ruggedized build and should be treated carefully. They are lightweight, plastic-bodied, and not designed for harsh conditions. Neither is waterproof or dustproof. The FujiFilm’s battery uses NP-45A cells, while Sony employs NP-BN1 batteries - not interchangeable and each requiring proprietary chargers.

User experience highlights:

• FujiFilm’s fixed lens means no lens interchangeability, no filters attachment - a limitation for those wanting creative flexibility.
• Sony supports multiple storage media formats (SD, SDHC, SDXC, and Memory Stick formats) enhancing convenience and compatibility across Sony devices.
• Connectivity is sparse on both: FujiFilm offers only USB 2.0, Sony adds HDMI output and Eye-Fi wireless card support - a niche but useful feature for immediate image transfer without cables.

Price-to-Performance: Which One Is the Better Value?

At launch and current street prices hovering around $220 for FujiFilm and $188 for Sony WX9, the price gap is modest but meaningful given Sony’s superior specs and capabilities. The WX9’s better sensor, faster continuous shooting, optical stabilization, higher resolution screen, and richer video recording justify this pricing.
