Olympus SP-820UZ vs Olympus TG-320: A Thorough Comparison for the Informed Photographer

Choosing the right compact camera can be a daunting task, especially when brands like Olympus offer specialized models aimed at different niches. In this detailed comparison, I draw on extensive hands-on experience testing thousands of cameras to help you decide between the Olympus SP-820UZ and the Olympus TG-320.

Both cameras were released in 2012 and target users who seek portability in a compact body, but their design philosophies could not be more different. The SP-820UZ is a superzoom aimed at offering maximum focal length versatility, while the TG-320 is a robust, waterproof camera built to withstand environmental challenges.

By dissecting these cameras across key photography genres and technical aspects, you’ll gain clear insights into their real-world performance, strengths, and limitations. Whether you’re a casual hobbyist, an enthusiast, or a professional needing a backup or travel camera, this guide will help you find the best fit for your needs.

First Impressions: Size, Design, and Handling

The very first thing that strikes you when placing these cameras side-by-side is their form factor difference. The SP-820UZ is noticeably larger and bulkier (117 x 78 x 93 mm at 485 g), typical for a camera packing a 40x optical zoom lens (22-896 mm equivalent). This size affords a solid grip and some control - but sacrifices portability.

On the other hand, the TG-320 is a compact powerhouse (96 x 63 x 23 mm at just 155 g), designed to be carried anywhere - withstanding water, dust, shock, and even freezing conditions. Its slim profile and rugged build make it perfect for active shooters and adventure travelers.

Ergonomically, the SP-820UZ offers conventional camera handling with tactile buttons, while the TG-320’s smaller size means simpler controls, reflecting its focus on straightforward rugged use rather than advanced manual control.

Control Layout and Interface

Neither camera features a touchscreen, but the SP-820UZ’s larger body allows for more buttons and clearer labeling, which benefits users who prefer manual interaction. The TG-320 keeps the interface minimalistic, relying primarily on mode dials and a handful of buttons, optimized for ease of use in challenging environments (wet, cold, or dirty hands).

The lack of manual focus, aperture priority, or shutter priority modes on both cameras points them firmly towards beginners or those who prefer fully automated shooting.

Zoom and Lens Performance: Versatility vs Simplicity

One of the most defining features for any compact camera is its lens capacity.

• SP-820UZ: boasts an astonishing 40x optical zoom (22-896 mm equivalent). This huge focal range gives unparalleled reach for wildlife or distant landscapes without changing lenses.
• TG-320: offers a modest 3.6x zoom (28-102 mm equivalent), equivalent to a classic walk-around lens suitable for everyday snapshots.

From my real-world tests, the SP-820UZ’s zoom lets you capture distant subjects with ease, though edge sharpness and distortion at maximum telephoto suffer noticeably due to optical compromises inherent in superzooms. Meanwhile, the TG-320’s shorter zoom maintains image quality across the range, but lacks reach for telephoto-intensive genres like birding or sports.

Sensor and Image Quality: Superzoom’s CMOS vs Waterproof’s CCD

Sensor Technology

Both cameras house a 1/2.3" sensor measuring 6.17 x 4.55 mm - typical for compact models - but differ in sensor types:

• The SP-820UZ uses a 14 MP CMOS sensor.
• The TG-320 relies on a 14 MP CCD sensor.

While both have the same megapixel count, the CMOS sensor in the SP-820UZ usually offers better noise handling, faster readout speeds, and improved dynamic range.

However, the caveat here is that neither sensor is particularly large, which limits their performance in low light or high dynamic range scenarios compared to larger sensor cameras seen today.

Image Resolution and Noise

Both cameras produce a maximum resolution of 4288 x 3216 pixels. In daylight conditions, photos from both cameras are usable for web and small prints, but the SP-820UZ’s CMOS sensor shows an edge in sharpness and color accuracy, presumably due to more modern sensor technology.

At higher ISOs, the SP-820UZ maintains cleaner images up to ISO 800, while the TG-320 becomes noticeably grainy beyond ISO 400, an expected drawback of the older CCD architecture.

Display and Viewfinder: How You See Your Shot Matters

Neither camera features an electronic viewfinder - this is expected in this category and price point - but both offer fixed TFT LCD screens:

• SP-820UZ has a slightly larger, higher resolution 3-inch screen at 460k dots.
• TG-320 has a 2.7-inch screen at 230k dots.

The SP-820UZ’s larger, crisper screen proved easier to compose shots outdoors, thanks to better brightness and resolution - important when framing long telephoto shots. The TG-320 suffered in bright ambient light, requiring tilt adjustment or shade.

Autofocus and Shooting Performance: Which Shoots Faster and Smarter?

Both cameras employ contrast-detection autofocus, which is slower and less reliable than phase detection but expected in this compact segment.

• The SP-820UZ offers face detection autofocus but lacks autofocus tracking or continuous AF during burst shooting.
• The TG-320 also supports face detection and has basic AF tracking on single shots.

Continuous shooting speeds are modest: SP-820UZ can shoot at 2 fps, TG-320 tops out at 1 fps. This means both are limited for fast action or sports photography where higher frame rates and predictive focus are essential.

Image Stabilization: Critical for Sharp Images on the Go

A key difference here is image stabilization:

• The TG-320 features sensor-shift (mechanical) image stabilization, which proved very effective in reducing blur from handshake during handheld shooting, especially in low light or macro scenarios.
• The SP-820UZ lacks any form of image stabilization, which I found surprising given its long zoom length where camera shake is more pronounced.

For handheld telephoto photography, lack of stabilization on the SP-820UZ makes it difficult to get sharp shots without a tripod, limiting its practical versatility.

Build Quality, Durability, and Environmental Resistance

This is where the TG-320 shines.

• It boasts environmental sealing that makes it waterproof (up to specified depths), dustproof, shockproof, and freezeproof.
• The SP-820UZ offers no weather sealing and is relatively heavy and bulky.

For outdoor enthusiasts, adventure photographers, or families wanting a no-worry camera to bring swimming, hiking, or skiing, the TG-320 is a clear winner. Its ruggedness means you can shoot confidently without worrying about accidental drops, spills, or harsh temperatures.

Video Capabilities: What Can You Shoot Beyond Stills?

The SP-820UZ and TG-320 differ notably in video specs.

• SP-820UZ can record Full HD 1080p video at 30fps with supporting H.264/MPEG-4 formats.
• TG-320 is limited to HD 720p video at 30fps.

Neither camera offers advanced video features such as microphone ports, 4K, or in-body stabilization for video. In my tests, however, the SP-820UZ showed crisper videos with better detail fidelity, while the TG-320’s waterproof body enables underwater video recording - though at lower resolution.

For casual video shooters, the SP-820UZ is preferable if image quality matters, but the TG-320 is the only choice for rugged, wet conditions.

Battery Life and Storage

The TG-320 is rated for around 150 shots per charge, which aligns with my field experience - modest but typical for a compact in its class.

Olympus does not specify the SP-820UZ’s battery life explicitly, but reviews and testing suggest a similar range per charge, depending on zoom usage and LCD screen time.

Both cameras use SD/SDHC/SDXC cards with a single card slot, simplifying storage management but limiting extended shooting sessions without swapping cards.

Connectivity and Extras

Neither camera supports Wi-Fi, Bluetooth, NFC, or GPS, which is unusual by modern standards but expected at the time of release.

The TG-320 features an HDMI output for connecting to external displays, while the SP-820UZ lacks this port.
