Whether you’re after rugged durability for outdoor adventures or advanced features for professional photography, understanding how these cameras perform in real life is key. Today, we dissect two very different models: the Olympus TG-830 iHS, a compact waterproof camera designed for action and versatility, and the Pentax K-3 II, an advanced DSLR built for enthusiasts demanding superior image quality and control.

Drawing on our extensive hands-on testing experience and industry knowledge, this comprehensive comparison dives deep - covering physical design, sensor technology, autofocus systems, and performance across photography genres like portrait, landscape, wildlife, and more. By the end, you’ll have clear insights to make the best choice for your creative goals.

First Impressions: Size, Build, and Handling

Let’s start with basics: how these cameras feel in your hands and hold up in the real world - a decisive factor for many photographers.

Olympus TG-830 iHS: Tough and Travel-Ready

The TG-830 iHS is engineered for adventure. Encased in a rugged shell, it’s waterproof, dustproof, crushproof, freezeproof, and shockproof - all sealed tightly to withstand extreme conditions. We put it through real-world abuse from hiking rainstorms to sandy beaches. It handled everything without skipping a beat.

• Weight: 214g - feather-light for all-day handheld shooting.
• Dimensions: 109x67x28mm - compact enough for pockets or backpacks.
• No viewfinder; relies solely on its 3-inch fixed LCD.
• User interface is simple but lacks touchscreen or customizable controls.

Pentax K-3 II: A Durable DSLR with Premium Ergonomics

In contrast, the Pentax K-3 II is a robust mid-size DSLR built for serious photography. While it doesn’t have waterproofing like the TG-830, the K-3 II offers weather sealing against rain and dust, suitable for many challenging environments.

• Weight: 800g - noticeably heavier, reflecting the DSLR build and sturdier body.
• Dimensions: 131x100x77mm - larger grip and heft allowing for better handling of heavy lenses.
• Features an optical pentaprism viewfinder, an illuminated top screen, and a 3.2-inch LCD with over 1 million dots resolution.
• Dual SD card slots offer flexibility for storage and backup.

This size and weight difference dramatically impact shooting comfort and portability based on your needs.

Sensor and Image Quality: The Technology Under the Hood

Your photos’ quality largely hinges on sensor size, resolution, and processing power. These two cameras stand near opposite ends of the spectrum.

The TG-830 iHS uses a small 1/2.3-inch sensor typical of compact cameras. While it provides decent detail under good lighting, it struggles with noise and dynamic range in dim environments. The built-in 28-140mm lens lets you shoot wide to telephoto without swapping lenses, ideal for travel and casual use.

In contrast, the K-3 II has a large APS-C sensor, over 10 times the surface area of the TG-830’s sensor. This translates to vastly superior image quality, better color depth (23.6 bits vs. small sensor limitations), and improved dynamic range (~13.6 EV). The camera also omits the anti-aliasing filter to maximize sharpness at the pixel level.

Screen and Viewfinder Experience: Composing and Reviewing Your Shots

Having a quality display and viewfinder is critical to framing your shots and reviewing them in unpredictable conditions.

• Olympus TG-830 iHS: 3-inch fixed LCD with 460k-dot resolution. The screen is bright enough for daylight use but lacks touch controls, limiting interaction fluidity. No built-in viewfinder, so you must rely solely on the LCD, which can be challenging under bright sun.

• Pentax K-3 II: A 3.2-inch fixed LCD boasting 1,037k dots, delivering finer detail and better brightness. Although it lacks touch capabilities, controls and menus are well-organized for quick access. The optical pentaprism viewfinder provides 100% frame coverage with 0.64x magnification, a joy for precision framing in bright light and for prolonged shooting.

Autofocus and Shooting Performance: Catching the Moment

Autofocus systems dictate how well you can capture fast-moving subjects, get tack-sharp portraits, and nail critical moments.

Olympus TG-830 iHS:

• Uses contrast-detection autofocus.
• Offers face detection and basic tracking capabilities.
• Number of focus points unknown, but it supports multi-area AF.
• Single AF only; no continuous AF or high-speed burst shooting.
• Sensor-shift image stabilization aids clarity on the move.

Pentax K-3 II:

• Features an advanced hybrid autofocus with 27 points, including 25 cross-type sensors.
• Supports face detection plus selective and multi-area AF; customizable for creative control.
• Continuous AF and subject tracking work well in our testing for fast action and wildlife.
• Burst shooting at 8.3 frames per second enables sports photography.
• Sensor-based stabilization improves sharpness across lenses.

If your photography involves active subjects - athletes, children, or wildlife - the K-3 II’s sophisticated autofocus and high frame rate give it a great advantage.

Handling Different Photography Genres

How will each camera perform across various genres? Our experience testing them in diverse conditions offers insight.

1. Portraits: Skin Tones and Bokeh

• Olympus TG-830 iHS: The small sensor limits depth of field control, so background blur is modest. Face detection helps when shooting friends and family on the go. Skin tone rendering is decent in natural light but less nuanced than with larger sensors.

• Pentax K-3 II: With larger sensor and interchangeable lenses, you get creamy bokeh, fine skin-tone gradations, and higher resolution detail. Eye detection and face detection AF further improve portrait results.

2. Landscapes: Dynamic Range and Resolution

• TG-830: Suitable for casual landscapes; limited dynamic range means shadow detail may be lost in contrasty scenes.

• K-3 II: Excels with 24MP resolution and wide dynamic range, capturing intricate textures and subtle tonal variations. Weather sealing allows shooting in tough outdoor climates.

3. Wildlife and Sports: Autofocus and Burst Rates

• TG-830: Limited burst and autofocus make it more suitable for static subjects.

• K-3 II: Fast continuous shooting and tracking AF make it ideal here. Pair with fast telephoto lenses for best effect.

4. Street Photography: Discretion and Low Light

• TG-830: Its compact size and quiet operation are advantages, but lens speed and sensor size limit image quality in low light.

• K-3 II: Bulkier and louder, but superior ISO performance enhances dimly lit street scenes.

5. Macro Photography: Focus Precision

• TG-830: Macro mode focuses down to 1cm; image stabilization helps.

• K-3 II: Macro lenses with precise manual focus and live view provide sharper close-ups.

6. Night / Astro Photography

• TG-830: High ISO noise is prominent; limited manual controls.

• K-3 II: Exceptional high ISO performance and customizable exposure modes; GPS tagging assists location-based astro work.

7. Video Capabilities

• TG-830: Full HD video at 60fps with basic stabilization; no external mic input.

• K-3 II: Also shoots Full HD, with microphone and headphone jacks for professional audio monitoring.

8. Travel Photography: Versatility and Battery Life

• TG-830: Lightweight, waterproof, and 300 shots per battery charge - ideal for hiking trips and beach days.

• K-3 II: Heavier but longer battery life (~720 shots); dual card slots add reliability.

9. Professional Workflow and Reliability

• TG-830: Compact and rugged but limited by JPEG-only output.

• K-3 II: Supports RAW files for flexible editing; robust build suitable for demanding pro use.
