Olympus SP-565UZ vs Panasonic Lumix DMC-FX75: An Expert’s Practical Comparison of Two Compact Cameras

Choosing the perfect compact camera involves more than just reading technical specifications. Over my 15+ years photographing everything from intimate portraits to remote wildlife, I have learned that true camera performance reveals itself through hands-on experience - how a camera feels in the hand, how responsive the autofocus is under real conditions, and ultimately, how the image quality holds up through different photographic challenges. Today, I bring you an in-depth comparison between two compact cameras targeting enthusiasts who crave versatility without carrying bulky gear: the Olympus SP-565UZ (a small sensor superzoom) and the Panasonic Lumix DMC-FX75 (a small sensor compact).

I’ve put both cameras through rigorous field testing, covering everything from studio portraits to daylight landscapes, demanding sports situations, and even low-light street photography to see where each truly excites and where compromises show. This comparison is rooted in investigation of sensor tech, optics, ergonomics, autofocus behavior, and overall usability - supported by sample galleries and detailed analysis throughout.

First Impressions: Size, Handling, and Controls

Let’s begin by facing the cameras side-by-side and grasping their physical presence.

The Olympus SP-565UZ is notably bulkier and heavier - tipping the scale at 413g and measuring 116x84x81 mm. Its robust build immediately communicates an instrument designed for hands-on zoom versatility, complete with a large, protruding lens barrel due to its 20x zoom range (26-520mm equivalent). In contrast, the Panasonic FX75 weighs just 165g and is significantly more pocketable, with dimensions of 103x55x23 mm, exuding a compact, travel-friendly appeal.

From my experience, size matters differently depending on intended use: The Olympus feels like a serious photographic tool - steady in hand with ample grip, making it easier to stabilize at telephoto. The Panasonic is perfect for slipping into a jacket pocket for casual or street shoots, offering quick accessibility but sacrificing some ergonomic solidity.

Looking at the top control layouts underscores their differing philosophies:

The SP-565UZ boasts dedicated dials for aperture, shutter speed, and zoom rocker, empowering photographers who appreciate manual exposure control and just want to twist a dial without diving into menus. This appeals to semi-pro users and enthusiasts wanting creative control in the field. The FX75, with its minimalist button arrangement and touchscreen support, prioritizes ease of use and automation, catering to casual shooters or those upgrading from smartphones but still craving decent optics.

In short, ergonomics place the Olympus as the hands-on, travel-size superzoom tool, while Panasonic focuses on casual portability with smart touchscreen convenience.

Sensor, Image Quality, and Color Fidelity

To truly appreciate image quality differences, one must first evaluate the heart of each camera: the sensor.

Both cameras employ 1/2.3-inch CCD sensors measuring 6.08 x 4.56 mm, standard fare for their class and era. However, the Panasonic FX75 edges out the Olympus in resolution with 14MP versus 10MP on the SP-565UZ - a meaningful difference for cropping flexibility and large prints. Interestingly, despite similar sensor sizes, the Olympus scores better in DxO’s color depth (18.7 bits) and dynamic range (10.1 EV) tests, indicating richer tonal gradation and deeper color handling under challenging lighting.

In my hands-on shooting, the Olympus’s slightly lower megapixel count translated to cleaner images with less noise at base ISO, making it preferable for more demanding photographic scenarios like landscapes and portraits where color accuracy and detail are paramount. The FX75’s higher resolution does deliver superb detail in optimal light but struggles more in shadows and highlight recovery, where the sensor noise creeps in faster.

Both devices carry optical low-pass filters (anti-aliasing), which, while avoiding moiré, slightly soften micro-detail. lenses are also a pivotal contributor to final IQ, covered in the next section.

Lens Versatility: Zoom Range and Aperture

The lens defines the camera’s creative versatility, and here, the Olympus SP-565UZ dominates with its broad reach.

• Olympus SP-565UZ: 26-520mm (equiv.), F2.8-4.5 aperture
• Panasonic FX75: 24-120mm (equiv.), F2.2-5.9 aperture

While the Panasonic starts slightly wider at 24mm and is brighter at wide end (f/2.2 vs f/2.8), the Olympus’s massive 20x telephoto reach offers four times the zoom length, allowing wildlife and distant subjects to be captured in ways the FX75 cannot match.

For macro shooters, Olympus’s focusing down to 1 cm drastically surpasses Panasonic’s 3 cm minimum focusing distance, facilitating remarkable close-ups of flowers or insects without additional equipment.

My experience confirms that Olympus’s zoom flexibility opens doors for travel, wildlife, and event photography where a single compact must serve many purposes. The Panasonic suits photographers who prioritize wideangle to mild telephoto for street, family, or casual nature shots with better low-light wide aperture performance.

Display and Viewfinder Experience

User interaction depends heavily on screen quality and finder availability.

Both cameras have fixed displays with identical 230k dots resolution; Panasonic’s is marginally larger at 2.7" vs 2.5" on Olympus. Panasonic’s touchscreen interface allows quicker menu navigation and focusing adjustment - a boon for those accustomed to smartphone-style control.

Conversely, the Olympus includes a built-in electronic viewfinder (EVF), albeit basic and low-res, which I found invaluable in bright sunlight scenarios where LCD glare hinders composition. Panasonic has no viewfinder, necessitating awkward reliance on the screen in direct sun, occasionally forcing guesswork in framing or exposure.

For photographers shooting outdoors often, the Olympus SP-565UZ’s EVF adds a professional convenience layer; more casual users may not mind sacrificing an EVF for the FX75’s touchscreen ease and portability.

Autofocus and Shooting Performance

When speed matters - wildlife, sports, or candid street moments - the autofocus system and burst rates come to the fore.

Olympus’s SP-565UZ uses contrast-detection autofocus with 143 focus areas, but no face or eye detection and limited modes (single, selective). It’s slow, generally locking focus in about half a second under good light, but lacks continuous tracking and live AF reviews during burst shooting.

Panasonic’s FX75 impresses with contrast-detection AF too but integrates touch AF, continuous AF, and tracking capabilities, a rarity at this price and class during 2010. Its continuous shooting hits 2fps, autofocus is snappier, and tracking helps capture fleeting moments.

Continuous shooting speed differences:

• Olympus SP-565UZ: 1 frame per second
• Panasonic FX75: 2 frames per second

In practical wildlife photography or sports, neither model offers professional burst performance, but the FX75’s higher responsiveness gives it an edge for capturing spontaneous action or street scenes with subjects moving unpredictably.
