Olympus E-30 vs. Olympus TG-630 iHS: An Expert’s Comprehensive Comparison Across Photography Styles and Technologies

Choosing the right camera is a complex decision. Even within a single brand like Olympus, the gear varies widely - from rugged compacts engineered for adventure to mid-size DSLRs built for professional-level control and image quality. Today, I’m putting two very different Olympus cameras head to head: the Olympus E-30, a discontinued but respected mid-size DSLR launched in 2009, versus the compact TG-630 iHS, a rugged waterproof camera released in 2013. Both appeal to photographers prioritizing durability, Olympus’s trusted optics, and solid image processing for their time - but which suits your style and requirements?

Over many years of testing hundreds of cameras and lenses, I’ve learned that raw specifications only tell part of the story. What matters most is how these features translate into real-world use across a variety of genres, shooting scenarios, and workflows. I’ve spent hours examining each camera's build, controls, sensor output, autofocus, and handling under diverse conditions - from low-light sports events to macro shots in the wild - to deliver practical insights rooted in direct, side-by-side comparisons.

Let’s dive deep into the technical and experiential nuances of the E-30 versus the TG-630 iHS, and unpack their strengths and limitations for everything from portraiture to professional workflows. Along the way, I’ve integrated important visual comparisons to help illuminate critical differences.

A Tale of Two Olympus Cameras: From Mid-Size DSLR to Waterproof Compact

At first glance, these two seem to inhabit opposite ends of the Olympus lineup:

• The E-30 is an advanced DSLR, built on the Four Thirds sensor system with interchangeable lenses, designed primarily for enthusiasts and semi-pro photographers who want control, quality, and versatility.
• The TG-630 iHS is a tough compact intended for the adventurous photographer: fully waterproof, shockproof, and dustproof, it’s ideal for colorful, spontaneous shooting under rugged conditions - but with a tiny fixed lens and a much smaller sensor.

Before unpacking particular photo disciplines, let’s quickly size them up.

The E-30 sits significantly larger and heavier at 695 g and dimensions of 142 x 108 x 75 mm versus the lightweight 167 g TG-630 at 98 x 66 x 22 mm. This disparity is fundamental to their intended usage: the DSLR commands a presence suited for dedicated photographic outings, whereas the TG-630’s sleek compactness makes it the ideal everyday carry and extreme sports companion.

The E-30’s grip is sculpted for secure handling with interchangeable lenses, and its articulation screen enhances shooting flexibility. In contrast, the TG-630’s minimalistic design sacrifices some ergonomics but gains portability and durability.

In-Camera Design and Controls: Tastefully Traditional vs. Effortlessly Simple

Moving from dimensions to control layout, the contrast remains substantial.

The E-30 features an intuitive DSLR control scheme with dedicated dials, abounding buttons, and a top LCD that displays vital exposure data - a boon in shifting light and fast-paced shooting. Experienced shooters will appreciate direct access to shutter/aperture priority modes, exposure compensation, and custom white balance - all essentials for refined control.

Conversely, the TG-630 opts for a pared-down approach typical of rugged compacts: fewer buttons, no manual exposure modes, and reliance on automated shooting decisions. This simplicity favors casual users or those needing a dependable “point and shoot” in harsh environments but limits creative control.

Its rear 3-inch fixed screen offers generous resolution, but there’s no viewfinder - typical for compacts, though a disadvantage in bright sunlight or for composing action precisely. The E-30’s 2.7-inch fully articulated HyperCrystal II LCD with touchless live view and an optical pentaprism viewfinder ranks higher for critical manual framing.

Sensor Technologies and Image Quality: The Heart of the Matter

Under the hood lies probably the most critical difference: sensor size and quality.

The E-30 boasts a 17.3 x 13 mm Four Thirds CMOS sensor with 12 megapixels and an anti-aliasing filter. Its sensor area is approximately 225 mm² - offering significantly better light gathering capability than the TG-630’s compact 6.17 x 4.55 mm (28 mm²) 12 MP CMOS sensor.

In real-world testing, this means the E-30 produces cleaner images with more detailed gradations, superior color depth (21.3 bits at DxOmark), and a dynamic range plateau around 10.4 EV at base ISO 100. Its native ISO maxes at 3200, but noise management is effective up to this point, enabling usability in more challenging lighting without aggressive grain.

The TG-630, although packing the same nominal 12 MP resolution, suffers from the limitations imposed by its tiny sensor. Image quality under ideal lighting is surprisingly decent for a compact, but it exhibits significantly higher noise starting around ISO 400-800, with lower dynamic range and less nuanced color rendition. High ISO performance and shadow recovery are notably inferior - expected for the 1/2.3" sensor class.

Viewing and User Interface: What You See Shapes What You Get

Beyond sensor specs, how you preview and adjust your image matters tremendously. I found the E-30’s viewfinder critical for precise manual focus and exposure decisions, especially for professionals:

The E-30’s articulated LCD and optical viewfinder (“coverage” ~98%, magnification 0.56x) give photographers multiple options for composition, from high or low angles via the hinged screen to traditional eye-level shooting enhanced by an optical pentaprism.

In contrast, the TG-630’s fixed, relatively large 3-inch screen features a higher pixel count but lacks articulation or an EVF, forcing you to rely on it exclusively - even in bright sunlight, where glare can compromise visibility.

While both offer live view, the E-30’s implementation is more responsive and compatible with autofocus by both phase and contrast detection, assisting faster, more accurate focusing - especially relevant when swapping manual-focus lenses or using legacy optics.

Autofocus Systems: Speed, Accuracy, and Flexibility Under Fire

Nothing tests AF more thoroughly than wildlife and sports photography. Let’s evaluate these cameras’ autofocus capabilities.

The E-30 has a hybrid AF system combining 11 focus points (phase detection) and utilizes contrast detection in live view. It supports continuous AF, face detection, and selective multi-area focusing - features I’ve repeatedly verified to yield reliable lock-on in controlled burst modes, enabling shots of active subjects without excessive hunting.

However, it does not support animal eye autofocus or the latest AI-based tracking, limiting performance compared to modern systems. Its 5fps burst mode, while outpaced by newer cameras, remains respectable given its 2009 vintage.

The TG-630 iHS, meanwhile, leans on contrast-detection AF with fewer focus areas and no full manual focus option. It does support face detection and tracking, but only single-shot autofocus - not continuous. Burst mode is an equivalent 5fps but lacks the same tracking reliability under fast subject movement. Its AF struggles in low contrast or low light, a consequence of sensor size and algo limits.

In wildlife or sports scenarios - where speed, precision, and customizable AF zones are crucial - the E-30 considerably outperforms the TG-630.

Weatherproofing and Durability: Outdoor Enthusiast’s Dream Meets Studio Workhorse

The TG-630’s ruggedness is hard to beat for anyone chasing adventure:

• Waterproof to significant depths
• Dustproof, shockproof, and freezeproof certifications
• Compact and pocketable design

This makes the TG-630 ideal for underwater photography, mountaineering, or dusty festivals, with peace of mind that a splash or drop won’t end your shoot.

The E-30, by contrast, lacks weather sealing and environmental resistance, designed for controlled shooting environments or careful handling outdoors. It’s more fragile due to its DSLR construction but provides a robust magnesium alloy body with classic DSLR durability.

If you prioritize travel or action under extreme conditions, there’s no contest: the TG-630’s rugged design wins hands down.

Low noise at high ISO and robust long exposure capabilities matter.

• The E-30 supports exposure times up to 60 seconds, an advantage over the TG-630’s max 4 seconds shutter.

• Higher native ISO (3200) with better noise control benefits astrophotography.

• Full manual exposure modes impart delicate control.

• The TG-630’s high ISO goes up to 6400, but image noise degrades quality severely at anything past ISO 800.

• Manual exposure modes are unavailable; the longest shutter of 4 seconds is insufficient for detailed star trails.

• While not its forte, it suffices for casual nighttime snaps.

Video Capabilities

Video demands resolution, frame rate, and audio connectivity.

• The E-30 lacks video recording - no video modes at all. It remains a dedicated stills camera.

• This is a significant shortcoming compared to modern hybrids.

• The TG-630 offers Full HD (1920x1080) video at 60 fps with H.264 compression.

• It lacks external microphone and headphone ports, limiting audio control.

• Still, impressive for a 2013 compact, smoothing access to casual videography.
