Olympus E-620 vs Olympus TG-810: A Comprehensive Comparison for Every Photographer

Choosing the right camera is a pivotal decision for any photography enthusiast or professional. Olympus offers a broad catalog, blending innovation with reliability across different categories. Today, I’m diving deep into two Olympus models that, at first glance, could not be more different: the Olympus E-620, a compact entry-level DSLR targeting enthusiasts seeking better image quality and control; and the Olympus TG-810, a rugged, waterproof compact designed for adventurers needing durability and versatility in extreme conditions.

In this detailed hands-on comparison, based on years of personal camera testing and technical analysis, I’ll guide you through every critical aspect - from sensor performance and autofocus capabilities to usability, durability, and photographic versatility. Whether you're into portraits, landscapes, wildlife, or travel, this review will clarify which camera meets your specific needs. Let’s get started.

First Impressions: Size, Build, and Ergonomics

When assessing any camera, the physical design is foundational to user experience. I always begin testing by handling cameras side-by-side to gauge ergonomics, ease of control layout, and portability.

Olympus E-620: Compact DSLR with Traditional Handling

The E-620 is a compact SLR with dimensions of 130x94x60 mm and weighs around 500 g with battery. Its body is decidedly DSLR in style, featuring an engraved pentamirror viewfinder and a fully articulated 2.7-inch HyperCrystal LCD. Handling felt comfortable for extended shooting sessions, largely due to the ergonomic grip which accommodates a two-hand hold easily.

The camera’s control layout reflects its 2009 release date - multi-dial setup with clearly defined shutter speed, aperture, and exposure compensation controls. My tests confirmed that the weight and heft contribute to stability, particularly useful for telephoto or macro lenses that the Micro Four Thirds mount encourages.

Olympus TG-810: Rugged, Pocketable Adventure Tool

In contrast, the TG-810 is a tough, compact point-and-shoot camera measuring just 100x65x26 mm and tipping the scales at 215 g. It fits comfortably in a jacket pocket, and its rugged design is instantly noticeable with sealed buttons and reinforced corners. This camera is waterproof (up to 10 m), dustproof, shockproof (2 m drops), and freezeproof (down to -10°C) - ideal for outdoor photographers and adventurous travelers.

Its fixed lens and absence of an optical viewfinder point to leisure and quick-snapping rather than deliberate composition. The 3-inch, 920k-dot fixed TFT LCD is bright and detailed, but being non-articulated restricts shooting angles somewhat.

Sensor Technology and Image Quality: The Core of Every Camera

An uncompromising comparison must start with sensors - the backbone for image quality, dynamic range, and low-light performance.

Olympus E-620: Four Thirds CMOS Sensor with Good Balance

The E-620 sports a Four Thirds CMOS sensor measuring 17.3x13 mm with a 12-megapixel resolution delivering 4032 x 3024 pixels. Four Thirds sensors strike a balance between APS-C and Micro Four Thirds formats, providing better noise control and image quality compared to smaller sensors.

According to DxOMark metrics and from my hands-on shooting experience, the E-620 achieves a respectable dynamic range of 10.3 stops and a color depth of 21.3 bits - making it viable for landscapes and studio portraiture requiring smooth tones and rich detail. ISO sensitivity ranges from 100 to 3200, delivering clean results up to 800 ISO, and acceptable noise beyond that in moderate low-light.

Olympus TG-810: Small 1/2.3" CCD Sensor

The TG-810 has a much smaller 1/2.3" CCD sensor (6.17x4.55 mm), but it ups the resolution to 14 megapixels (4288 x 3216 pixels). While this higher pixel count sounds impressive on paper, the physical sensor size severely limits light-gathering capacity, impacting noise handling and dynamic range. The ISO tops out at 1600, with moderate noise levels even at base ISO 80.

The image processor here is the same TruePic III+ found in the E-620, but the smaller sensor technology and compact form factor circle in different performance expectations: excellent for daylight and casual photography but not intended for professional-grade quality.

Autofocus and Speed: Tracking the Action

For wildlife, sports, and street photography, autofocus (AF) performance and frame rates are pivotal.

E-620: 7 AF Points with Hybrid AF System

The E-620 uses a hybrid autofocus system combining both contrast and phase detection via 7 AF points (cross-type info unknown). It offers single, continuous, and selective AF modes, alongside face detection in live view. Testing showed:

• AF acquisition: Fairly quick in good light, with some hunting in low light.
• Tracking: Reasonably reliable but not optimized for fast-moving subjects.
• Continuous shooting: 4 fps burst rate, suitable for casual sports but falls short of dedicated sports cameras.

TG-810: Contrast-Detection AF with Limited Speed

The TG-810 implements contrast detection AF with face detection and multi-area focus. However, continuous shooting is limited to a sluggish 1 fps burst. Its autofocus is reliable for static scenes and casual snapshots, but it struggles with moving subjects due to slow acquisition and tracking delays.

Usability: Controls, Interface, and Viewfinding

Interface quality can make or break your engagement with a camera.

Olympus E-620 Interface and Viewfinder

The E-620 provides an optical pentamirror viewfinder with 95% coverage and 0.48x magnification. While not as bright or accurate as DSLR pentaprisms, it delivers a traditional framing experience preferred by many composers.

Its fully articulated 2.7-inch LCD enables flexible shooting angles, especially helpful for macro and video work. The ~230k-dot resolution isn’t dazzling by modern standards but was respectable for its time.

TG-810 LCD Brightness and Simplified Controls

The TG-810’s 3-inch 920k-dot screen offers a crisp and bright image preview, crucial in bright outdoor conditions where other cameras might falter. This screen is fixed, limiting versatility in composing from unusual angles.

Without an electronic or optical viewfinder, GG-screen shooting is mandatory, which can challenge stability in sunlight or action shots.

Lens Ecosystem and Optical Versatility

One of the major advantages of interchangeable lens cameras is the ability to adapt optics to your style.

E-620: Micro Four Thirds Mount Unlocks Creative Freedom

The E-620 uses the Micro Four Thirds lens mount, compatible with a wide, mature lineup of lenses from Olympus and other manufacturers. This ecosystem offers:

• Fast primes for portraits and low light
• Telephoto zooms for wildlife and sports
• Macro lenses offering close focus and sharpness
• Ultra-wide and fisheye lenses for landscapes and creative effects

Having tried multiple lenses myself, the mount flexibility allows photographers to tailor gear for all needs and upgrade as skills improve. Also, sensor stabilization aids handheld shots significantly.

TG-810: Fixed 28–140mm Equivalent Lens

The TG-810 has a built-in zoom lens covering a standard range (wide 28mm to telephoto 140mm, 5x optical zoom) with a maximum aperture of f/3.9–5.9. This lens is versatile for travel snapshots but limited in aperture and reach compared to interchangeable optics.

Image Stabilization: Handheld Performance

Both cameras feature sensor-based image stabilization, critical for reducing blur.

• E-620: Sensor-shift stabilization helps when shooting at slow shutter speeds and with long lenses.
• TG-810: Sensor-shift stabilization combined with rugged body helps compensate for shakes in difficult conditions.

In practice, the E-620’s IS is more effective due to larger sensor and lens options. The TG-810’s stabilization is good for point-and-shoot convenience outdoors.
