Olympus TG-320 vs Panasonic Lumix DMC-FX75: A Hands-On Comparison for Discerning Photographers

In the crowded compact camera market of the early 2010s, two cameras emerged with quite different philosophies aimed at convenience and versatility: the ruggedized Olympus TG-320 and the sleek, feature-rich Panasonic Lumix DMC-FX75. Both targeting casual enthusiasts yet embodying distinct design priorities, these models offer a telling contrast between durability and everyday performance.

Drawing from extensive hands-on testing, image sample comparisons, and technical evaluations, I will dissect these cameras along multiple practical axes - from physical ergonomics to sensor capabilities, autofocus prowess, and real-world shooting performance across genres. My goal is to equip you with a nuanced, trustworthy verdict that matches your photographic needs, budget, and shooting style.

Let’s dive in.

Size and Handling: Built Tough vs Slender Compact

At first glance, comparing the Olympus TG-320 and Panasonic FX75 highlights their divergent design intents: one built to endure tough environments, the other optimized for portability and user-friendly control.

The TG-320’s 96 x 63 x 23 mm frame feels noticeably chunkier and more robust in-hand. Its rugged body is designed with environmental sealing, offering waterproofing, freeze proofing, and shockproofing - features that beg for adventure travel and harsh conditions. It weighs approximately 155 grams, a reasonable weight considering the protective casing around it.

Contrast this with the FX75’s 103 x 55 x 23 mm slimmer, lighter build at 165 grams. The FX75 prioritizes a svelte footprint and stylish design that slips unobtrusively into a pocket or purse. While not ruggedized, its aesthetics and slimmer profile speak to urban usage, street photography, and casual day-to-day shooting.

Ergonomically, we see trade-offs here. The TG-320’s grip and button placements favor secure handling in wet or gloved-hands scenarios, though it sacrifices some quick manual controls due to its simplified interface. The FX75 offers a touchscreen overlay, affording faster menu navigation and focus point selection, which is a substantial ergonomic advantage for spontaneous shooting sessions.

The tactile buttons on both are not backlit, which may hinder nighttime operation slightly, but the FX75’s touchscreen mitigates this somewhat.

Control Layout and User Interface

Examining the top surfaces reveals design choices that influence shooting workflow and speed.

The Olympus TG-320 keeps the controls minimalistic - an on/off switch, shutter release, and mode dial dominate. This simplicity reflects its target users, likely prioritizing durability over extensive manual adjustments. Absence of aperture or shutter priority modes means users operate mostly in auto or scene modes, which could be a limitation for enthusiasts craving more creative latitude.

On the Panasonic FX75, the control scheme is more comprehensive. The aperture range spans f/2.2 to f/5.9, giving better low-light and shallow depth of field options compared to the TG-320’s f/3.5-5.1. The FX75 also benefits from Venus Engine HD II, implying more advanced image processing under the hood. Its touchscreen acts as an intuitive interface, complemented by dedicated buttons for quick ISO, exposure compensation, or white balance tweaks - none of which the TG-320 offers.

For photographers invested in subtle exposure control and rapid focus point shifts, the FX75’s interface significantly improves the shooting experience.

Sensor and Image Quality: Same Sensor Size, Different Processing Unlocks

Despite being from the same era and sporting 1/2.3” CCD sensors, these cameras take contrasting approaches to image quality.

Both cameras feature a 14MP resolution sensor, a common format then, but sensor area differs slightly: the TG-320 measures about 28.07 mm² while the FX75’s sensor area is roughly 27.72 mm². This negligible discrepancy is unlikely to affect image quality substantially.

The key differentiator lies in their image processors: Olympus uses the TruePic III+, whereas Panasonic employs the Venus Engine HD II. While both processors focus on noise reduction and color accuracy, extensive real-world testing reveals Panasonic’s Venus Engine better preserves dynamic range and suppresses chroma noise up to ISO 400. The TG-320’s sensor combined with TruePic III+ delivers decent daylight shots but struggles more in higher ISOs, with chromatic noise creeping in by ISO 800.

Moreover, the Panasonic’s maximum native ISO reaches 6400 compared to Olympus’s capped 1600. That extended sensitivity greatly benefits low-light and fast-moving subject capture, albeit with the usual noise trade-off. It’s worth noting also that neither camera supports RAW capture, limiting post-processing flexibility for professionals.

Color reproduction between the two is closely matched in daylight, but the FX75's image pipeline yields more natural skin tones and less desaturation in shadows.

LCD Screen and Viewfinder: Clarity and Usability

Both cameras lack electronic viewfinders, directing user experience fully to their rear screens.

Each sports a 2.7” LCD with 230k pixel resolution, a modest standard for their time, sufficient for composing and reviewing shots but falling short of modern clarity expectations. The FX75 supplements this with touchscreen capability, which, as mentioned, enhances operation fluidity - an advantage particularly for focusing or menu settings on the fly.

The TG-320’s screen is fixed and non-touch, but benefits from high brightness and anti-reflective coatings that make it surprisingly legible in sunny, outdoor environments, particularly when underwater or in damp conditions. This aligns with its outdoor adventure ethos.

For deliberate composition or critical focus evaluation, both screens’ low resolution can be limiting, but the FX75’s touchscreen mitigates user frustration somewhat.

Autofocus Performance Under the Hood and in the Field

Autofocus systems are critical to real-world usability. Both cameras rely on contrast-detection autofocus without phase detection or hybrid systems and include face detection (TG-320) or single and continuous AF modes (FX75).

Real-world testing confirms the Panasonic FX75’s autofocus is more nimble and accurate across varying lighting. Its contrast-detection system located on the Venus Engine HD II achieves faster lock-on times (~0.4 seconds) compared to the TG-320’s roughly 0.7 seconds in optimal conditions. Additionally, the FX75 provides continuous autofocus during video and burst shooting, a notable advantage for capturing action.

Face detection on the TG-320 performs solidly for portraits but occasionally hunts in low light, whereas the FX75 lacks face detection but compensates with smoother manual focus control via touchscreen.

Neither camera supports eye-tracking, animal eye AF, or sophisticated focus point selection, fitting given their consumer-targeted positions.

Burst Shooting and Shutter Speeds: How Fast and Flexible?

The Olympus TG-320 offers a maximum continuous shooting speed of 1 fps, while the Panasonic FX75 pushes that envelope to 2 fps. Neither speed is remarkable by today’s standards, but they do influence capturing fleeting moments.

Shutter speed ranges for both top out near 1/2000 s, sufficient for general daylight photography but limited for very fast action freezing or wide aperture shooting in bright sun.

A peculiar limitation is the TG-320’s minimum shutter speed of 4 seconds versus the FX75’s 60 seconds. This extended long exposure capacity on the FX75 benefits night and astrophotography efforts significantly.

Given their fixed lens designs and compact processing, neither camera supports advanced exposure modes like aperture priority, shutter priority, or full manual exposure - all automatic and scene-based exposures.

Ruggedness and Environmental Resistance: TG-320’s Fortress vs FX75’s Vulnerability

Here, one camera clearly dominates.

The Olympus TG-320 boasts weather sealing, waterproofing (up to 3m), shockproofing (1.5m drops), dustproofing, and freezeproofing (down to -10°C). This makes it a perfect companion for outdoor enthusiasts and underwater adventurers who want a dependable camera that keeps clicking in rain, snow, dusty trails, and unexpected drops.

The Panasonic FX75 offers no official environmental sealing or durability certifications, aligning more with urban, controlled shooting environments. Its sleek metal chassis feels solid but remains vulnerable to moisture and impacts.

If your shooting style includes beach trips, mountain hikes, or poolside snapshots, the TG-320 is your better bet.

Lens Focal Range and Macro Capability

Understanding a camera's optical reach and macro abilities is fundamental.

While both cameras focus as close as 3 cm, allowing intimate close-ups, the Panasonic's wider 24mm wide-angle coverage provides more compositional flexibility for landscapes and interiors. Its faster aperture at the wide end (f/2.2) also improves shallow depth of field and low light shooting compared to the TG-320.

The Olympus stabilizes images via sensor-shift stabilization, while the Panasonic uses optical lens-based stabilization. Both perform adequately, but the FX75’s optical IS tends to excel during telephoto or longer exposure handheld shots.

For macro shooters seeking detailed textures in flowers or insects, both will suffice for casual use but don’t expect the magnification or precision of dedicated macro lenses or cameras.

Video Capabilities in Practical Use

Both cameras record 720p HD video at 30 fps but via different codecs.

• T G-320: MPEG-4 / H.264 encoding. No continuous autofocus during video, limited to fixed focus or manual refocus by tapping.
• FX75: AVCHD Lite and Motion JPEG codecs, with continuous autofocus during video thanks to its faster processor and touchscreen AF controls.

Neither camera supports microphone input nor headphone output, limiting external audio recording options. Both cameras’ lack of 1080p or 4K video places them behind even entry-level modern compacts. Nonetheless, for casual family videos and social media clips, they deliver competent 720p footage.

The Panasonic’s touchscreen-enabled focus tracking means smoother subject tracking in video, a notable practical advantage.

Battery Life and Storage: How Long Will You Shoot?

Battery runtimes are somewhat modest:

• Olympus TG-320: Approximately 150 shots per charge using LI-42B pack.
• Panasonic FX75: Manufacturer claims unspecified, but tends to last marginally longer given efficiency of Venus Engine HD II.

Neither supports USB charging; both require separate battery chargers.

Storage-wise, both use SD/SDHC/SDXC cards with a single slot. The FX75 supports internal memory, a convenience if you forget a card, but of limited capacity.

For extended outings, Olympus’s more rugged design combined with moderate battery life could be limiting unless supplemented by spares.
