Olympus SP-820UZ vs Olympus TG-4: A Hands-On Comparison for Photography Enthusiasts

When it comes to Olympus’s compact camera lineup, two models stand out in very different corners of the field: the Olympus SP-820UZ, a superzoom aimed at versatile everyday shooting, and the ruggedized Olympus Tough TG-4, built for adventure and harsh environments. Though they share the same brand pedigree, these cameras cater to distinct photographic needs, with contrasting design philosophies, feature sets, and usage profiles.

Over dozens of hours testing and comparing these two cameras in both controlled and real-world conditions, I’ve developed a nuanced understanding of where each excels – and more importantly, who should consider which model. In this detailed comparison, I’ll break down their core strengths and weaknesses across technical specs, ergonomics, image quality, autofocus, video, and more. If you’re weighing these two Olympus compacts for your next purchase, this guide will give you the in-depth, practical insights you need to choose with confidence.

Getting Familiar: Size, Build Quality, and Ergonomics

The Olympus SP-820UZ and TG-4 adopt very different physical designs that speak to their core audiences.

The SP-820UZ is a chunkier compact, designed like a prosumer superzoom camera with a hefty 40x optical zoom range. It measures approximately 117x78x93 mm and weighs in at 485 grams - fairly substantial for a point-and-shoot, offering a firm grip and a more DSLR-like feel. In contrast, the TG-4 is noticeably smaller and lighter - 112x66x31 mm and only 247 grams. Its thickness is deceptive, as it packs ruggedization features that come with added durability but not bulk.

In-hand ergonomics clearly favor the TG-4 for outdoor portability and adventure use, with a robust rubberized grip and easy-to-use buttons designed for wet or gloved hands. The SP-820UZ’s larger body benefits from a deep grip and clearly labeled dials, but it’s less suited for rough handling or extreme conditions.

Examining the top view layout, the differences become even more apparent. The SP-820UZ sports a more traditional layout with a mode dial, zoom lever around the shutter, and dedicated playback and function buttons - straightforward and tactile but reflecting an older design ethos. The TG-4 pares down controls to essential buttons, optimized for quick operation rather than extensive manual tweaking in the field.

In summary, if you prioritize ruggedness and portability, the TG-4’s design is purpose-built for your needs. The SP-820UZ offers a bulkier form but that mass affords greater grip stability and zoom versatility - key for travelers who prefer shooting at a desk or tripod as much as on the move.

Sensor and Image Quality: What Does Each Camera Deliver?

Both cameras share a 1/2.3-inch sensor size but diverge on sensor design, resolution, and image processing that critically affect output quality.

The SP-820UZ utilizes a 14MP CMOS sensor with an anti-aliasing filter, while the TG-4 steps up the resolution to 16MP with a BSI-CMOS (backside-illuminated sensor), also carrying the anti-aliasing filter. The BSI design on the TG-4 notably improves low-light sensitivity and dynamic range, a significant advantage given the camera’s target outdoor and underwater environments.

The raw sensor size details look like this:

In practice, the TG-4’s sensor and TruePic VII image processor generate cleaner images with better detail retention at higher ISOs (up to ISO 6400 native) than the older SP-820UZ. The SP-820UZ’s older sensor technology results in heavier noise above ISO 400, limiting its use in dim lighting.

Resolution-wise, the TG-4 slightly outperforms with a max image size of 4608 x 3456 pixels compared to the SP-820UZ’s 4288 x 3216 pixels - a modest but noteworthy difference for large prints or cropping flexibility.

However, I’m mindful that the SP-820UZ's extended focal range can sometimes compensate for its sensor limitations by allowing tight telephoto framing without digital zoom, which is significant for budget superzoom users.

Mastering Manual Controls and Focusing

Autofocus and manual control are frontline features for any photographer - but these Olympus models take different approaches.

The SP-820UZ offers only contrast-detection autofocus with face detection but no continuous AF tracking, manual focus, or focus stacking. It’s serviceable for casual shooting but feels sluggish when locking focus, especially at long zoom ranges.

The TG-4, on the other hand, shines with a more sophisticated 25-point contrast-detection AF system supporting continuous autofocus and tracking, as well as manual focus with focus peaking - a rarity in rugged compacts. It also supports focus bracketing and focus stacking, attractive to macro and detail-oriented users.

While neither camera offers electronic viewfinders, both have a 3-inch screen with 460k dots resolution. The TG-4’s display is brighter and more visible in daylight, critical for outdoor shooting, while the SP-820UZ’s LCD feels flat and less responsive during tracking or quick framing adjustments. There’s no touchscreen functionality on either, but the TG-4’s menu system is more intuitive with logical grouping of settings.

For macro enthusiasts, the TG-4 is a clear winner. Its 1cm macro focusing capability, paired with manual focus and stabilization, facilitates precise close-ups of insects or intricate textures impossible to achieve effectively on the SP-820UZ.

Zoom Range and Lens Considerations

If zoom versatility is your priority, the SP-820UZ’s 22–896 mm equivalent (40x zoom) is a standout feature unmatched by the TG-4’s more modest 25–100 mm (4x zoom).

The TG-4’s lens is tailored toward wide-angle (for landscapes and underwater shooting) and short telephoto, favoring optical quality and speed (aperture F2.0–4.9) rather than reach. The fast wide aperture is a boon for low-light and shallow depth-of-field effects.

The SP-820UZ’s far-reaching zoom is slower (F3.4–5.7) but excellent for spotting distant wildlife or action without changing lenses - important given it has a fixed lens mount and no interchangeable lens capability.

If you crave grab-and-go flexibility with an emphasis on telephoto reach, the SP-820UZ is still a reliable tool, though the lens image quality softens a bit at maximum zoom lengths.

Performance in Key Photography Genres: How Do They Stack Up?

Taking each camera's feature set into practical domains illuminate their true potential for various photographer profiles. The field tests were carried out across a mix of studio setups, controlled outdoor environments, and spontaneous shooting scenarios.

Portrait Photography

For portraits, especially skin tones and eye detection, the TG-4’s face detect autofocus is superior and more reliable in mixed lighting. Its faster lens at the wide end helps achieve desirable background blur, rivaling traditional compact cameras. Unfortunately, neither camera features eye detection or animal eye AF, so professional portraiture requiring pinpoint AF remains out of reach.

The SP-820UZ’s telephoto zoom enables tight framing from a distance – useful for candid portraits – but slower and less accurate autofocus can result in missed sharpness.

Landscape Photography

Here, the TG-4’s improved sensor and broader ISO range yield better dynamic range and color rendition, a crucial advantage in high-contrast outdoor scenes. Weather sealing, dustproofing, and waterproof construction let you confidently shoot in challenging weather.

The SP-820UZ lacks environmental sealing, meaning landscape hiking in mist or rain requires extra care. However, its extended zoom lets you isolate distant features without changing gear.

Wildlife Photography

In this category, the SP-820UZ’s 40x zoom is immediately enticing, providing reach that far exceeds the TG-4, which maxes out at 100mm equivalent. Yet, the SP-820UZ’s low 2 fps continuous shooting and slower autofocus limit capturing fast wildlife movements.

The TG-4 offers 5 fps burst, continuous AF tracking, and better autofocus responsiveness but is handicapped by focal reach. Neither camera matches DSLRs or mirrorless systems for wildlife action, but for casual shooting, SP-820UZ’s zoom distance gains favor.

Sports Photography

Tracking and frame rate are crucial here. The TG-4’s 5 fps burst and continuous AF tracking make it more capable for moderate sports action, especially outdoors. The SP-820UZ’s 2 fps burst is noticeably limiting, and its autofocus tends to hunt under rapid changes.

Low-light sports benefit from the TG-4’s wider aperture and stabilized sensor, but ultimately neither camera can compete with dedicated sport cameras or advanced mirrorless for pro-level results.

Street Photography

In street scenarios, the TG-4’s compact size, discreet body, and weather resilience enhance spontaneous capture in varied conditions. Its quieter shutter and faster AF let you react quickly.

The SP-820UZ’s bulk and longer lens draw more attention, and startup times can feel slow, detracting from candidness. For street shooters valuing stealth and portability, the TG-4 stands out.

Macro Photography

This category clearly highlights the TG-4’s strengths: macro focus down to 1cm, focus stacking, and superior stabilization make it a versatile insect and flower shooter’s delight. The SP-820UZ has macro mode too but lacks manual focus, making precise close shots challenging.

Night and Astro Photography

Low-light sensor performance matters here. The TG-4’s BSI-CMOS sensor and ISO 6400 ceiling offer usable ISO performance with less noise than the SP-820UZ. That said, the SP-820UZ’s lack of image stabilization and limited shutter options hinder night capability.

Neither camera supports bulb or long exposure controls needed for astrophotography, but the TG-4’s better high ISO makes it the choice for casual night sky work.

Video Capabilities

Both offer 1080p full HD video at 30fps, but the TG-4 adds the benefit of sensor-shift image stabilization, producing noticeably smoother footage. The SP-820UZ lacks stabilization, so handheld video tends to be shaky, especially at telephoto.

Neither camera supports external microphones, limiting audio quality for video projects.

Travel Photography

Travel photographers demand light, reliable, and versatile gear. The TG-4’s waterproof and rugged body is travel-ready for adventurous trips - rain, beach, or mountain alike. Its longer battery life (about 380 shots) fuels all-day shoots.

The SP-820UZ’s superzoom is a great travel companion if you prioritize framing flexibility, but its heavier size and less sturdy build make it less ideal for backpacking and rugged conditions.
