Olympus E-3 vs Olympus TG-320

Olympus E-3 vs Olympus TG-320: A Deep Dive Comparison Across Photography Genres

When Olympus launched the E-3 in early 2008, it was a bold statement in the world of advanced DSLRs. Fast forward to 2012, and the TG-320 arrived as a rugged, waterproof compact aimed at a different user altogether. At first glance, comparing these two feels like apples to oranges - a robust DSLR powerhouse versus a tough point-and-shoot. Yet, our role here is to go beyond first impressions and unravel what each camera delivers across photography disciplines, technical metrics, and put them head-to-head for enthusiasts seeking practical guidance.

I’ve spent several weeks testing both cameras under varied conditions - from studio portraits to gritty street scenes, dramatic landscapes to grueling wildlife shoots - scrutinizing sensor performance, autofocus, ergonomics, and more. Let’s walk through their DNA, and see how each fares where it truly counts.

Size, Feel, and Control: Built for Different Worlds

The E-3 is an unapologetic DSLR with a magnesium alloy body, weighing in at 890 grams - solid, reassuring in-hand, and shaped for extended shooting sessions. Its size (142x116x75mm) and heft provide classic camera confidence. The handgrip is deep and textured, offering a secure hold with thick gloves or in the rain - which makes sense given Olympus’s environmental sealing.

The TG-320, at just 155 grams and a compact 96x63x23mm, is barely noticeable in a jacket pocket or day pack. Its build is shockproof, dustproof, freezeproof, and waterproof - a marvelous feat of engineering. The ruggedness is clear: this camera invites you to go where the E-3 would hesitate and shields you from the elements at a fraction of the weight.

But small often means compromise: the TG-320’s controls are minimal and the grip tiny. For anyone serious about manual operation, this feels decidedly limiting, though casual shooters might appreciate the straightforward layout.

On the control front, the E-3 sports a traditional DSLR interface with dedicated dials for shutter speed, exposure compensation, and a top LCD panel for at-a-glance info. Buttons are spread logically, and importantly, they’re not too small. It’s not just a powerhouse in specs, but in user experience as well.

The TG-320, by contrast, pares the controls down to the bare essentials - no manual exposure modes, no shutter priority, and no aperture priority. This is a point-and-shoot to snap and go, with user interfaces simplified accordingly.

Sensor and Image Quality: Standards Meet Convenience

Here’s where the biggest divergence lies.

The E-3 features a Four Thirds CMOS sensor measuring 17.3 x 13mm with 10 megapixels. Larger than the TG-320’s tiny 1/2.3” CCD sensor (6.17 x 4.55 mm) with 14 megapixels, the E-3’s sensor offers a decisive advantage in light gathering, dynamic range, and low-light performance. Olympus’s choice of a CMOS sensor on the E-3 was forward-thinking in 2008, capitalizing on better noise handling and faster readouts for continuous shooting.

In real-world testing, the E-3’s images exhibit richer color depth and superior dynamic range - critical for landscapes and portraits requiring nuance in shadows and highlights. Skin tones retain subtlety without leaning toward oversaturation, which can sometimes plague compacts. DxO Mark’s measurements echo this, assigning the E-3 an overall score of 56, with impressive color depth (21.6 bits) and a dynamic range of 10.5 EV.

The TG-320’s higher megapixel count on a tiny sensor results in more noise at modest ISO settings. Its max native ISO caps at 1600 (compared to 3200 on the E-3), and in comparisons within identical scenes, the compact’s images show understandably more grain and lower microcontrast. Yet, for quick snapshots under bright daylight or underwater, the sensor isn’t a disadvantage - it delivers solid output for its class.

The E-3’s lack of raw support on the TG-320 is a significant gap. Professionals and enthusiasts who want to push their images in post-production will find the TG-320 limiting. The E-3’s inclusion of raw files is a major plus in flexible workflows.

Handling and Interface: Articulated vs Fixed Screens

The E-3 is equipped with a fully articulated 2.5-inch screen (230k dots), a boon for shooting at awkward angles or macro work where low or high viewpoints are common. While not high-res by today’s standards, the articulation and exposure simulation in live view add user-friendly versatility.

The TG-320’s fixed 2.7-inch LCD, also at 230k dots, is simple and bright, adequate for composing in most conditions. However, because of its fixed design, it lacks the compositional freedom the E-3 provides. The lack of an electronic or optical viewfinder on the TG-320 can be a challenge in bright environments.

Both use resistive, non-touch LCDs, reflecting their era and target audiences.

Focus Systems in Action: Precision vs Point-and-Shoot

Olympus configured the E-3 with an 11-point phase-detect autofocus system (5 cross-type sensors). This system performed admirably during my diverse shooting sessions - quick to lock focus on moving subjects, reliable in low light, and flexible enough for selective focus needs.

The TG-320 relies on contrast-detection AF with face detection capabilities but lacks phase-detection entirely. This leads to slower autofocus acquisition and some hunting when lighting is less than ideal. The macro mode, however, performed acceptably given the fixed lens, allowing close focusing down to 3 cm, useful for casual macro snaps.

While the E-3 allows continuous AF tracking (useful during sports or wildlife), the TG-320 offers only single AF with limited tracking ability, constraining it in more dynamic shooting scenarios.

Photography Disciplines Evaluated

Let’s put both cameras under the spotlight across common photographic genres.

Portrait Photography

The E-3 shines when it comes to rendering skin tones accurately and producing attractive bokeh, thanks to interchangeable lenses and a large sensor aperture range. Its optical viewfinder aids precise framing and eye-detection autofocus (while basic in this model) helps nail focus on eyes, vital for portraits.

The TG-320’s fixed zoom lens (28-102mm equivalent) and small sensor limit subject isolation ability and bokeh quality. While the camera does offer face detection, its output is softer and less nuanced in tone rendition.

For serious portrait work, the E-3 is clearly the better tool.

Landscape Photography

The Four Thirds sensor and lens interchangeability give the E-3 a leg up in dynamic range, tonal gradation, and resolution for landscapes. Environmental sealing helps when shooting outdoors in challenging weather.

Conversely, the TG-320, while waterproof and freezeproof, sacrifices bit depth and resolution. Still, its ruggedness makes it valuable if you expect to shoot where lenses and DSLRs would be vulnerable (kayaking, skiing).

Wildlife and Sports Photography

With burst rates of 5 fps and a responsive 11-point AF system, the E-3 can handle moderate action shooting. The 2.1x crop factor extends telephoto reach, ideal for wildlife photography with suitable lenses.

The TG-320’s single frame per second burst and slower AF make it unsuitable for action disciplines.

Street Photography

Here’s an interesting crossover.

The TG-320’s compact size, discreteness, and quick startup make it ideal for candid street shooting, especially in challenging environments like rain or dust. Its waterproof qualities mean you can shoot worry-free in various conditions.

The E-3, although more capable image-wise, is heavier and more conspicuous, making it less ideal for spontaneous street shots.

Macro Photography

The E-3 benefits from interchangeable macro lenses and accurate manual focus control, augmented by the articulated screen to compose low-angle shots.

The TG-320 offers a respectable 3cm minimum focusing distance, good for casual macro shots but limited by lack of focus stacking or bracketing features.

Night and Astro Photography

The E-3 can push ISO 3200 with reasonable noise, with sensor-based image stabilization aiding longer exposures handheld. Its full manual exposure modes, including shutter priority and bulb mode, are must-haves for night shooting.

The TG-320’s ISO ceiling is lower (1600), and exposure control is limited, which hinders creative night or astrophotography.

Video Capabilities

The TG-320 surprisingly offers 720p HD video at 30fps, with basic MPEG-4/H.264 encoding. It includes microphone auto adjustments but lacks external mic input.

The E-3 offers no video recording options at all - typical for DSLRs of its era.

Travel Photography

The compact, rugged TG-320 wins here hands down for travelers seeking convenience and durability. Its long battery life (150 shots per charge) and built-in waterproofing make it ideal for adventurous trips.

The E-3 is better suited for planned travel photography where image quality and flexibility matter more than size or weight. Its higher power consumption and bulk are trade-offs for advanced features.

Professional Workflow Integration

The E-3 supports raw capture, tethered shooting (via USB 2.0), and has a mature lens ecosystem. Its weather sealing, reliability, and file quality have stood the test of time in professional roles.

The TG-320, with no raw, limited controls, and basic connectivity, is aimed far from professional work, instead targeting casual or outdoor enthusiasts.

Build Quality and Weather Resistance: Olympus Keep it Rough

Both cameras score high in environmental resistance - the E-3 has serious weather sealing but isn’t waterproof; the TG-320 goes further, being waterproof up to a certain depth, freezeproof, and shockproof, ticking boxes for adventurers.

Rigorous testing showed the TG-320 enduring rain, submersion, and freezing temps with no operational hiccups. The E-3, handled carefully, resists dust and moisture but demands care around heavy rain.

Battery and Storage: Practical Considerations

The TG-320 uses the Olympus LI-42B battery, providing about 150 shots per charge - modest, but manageable given its class. The E-3’s battery life metrics aren’t well published but generally outperform compacts, offering more durability for sustained sessions.

Storage-wise, the E-3 uses both Compact Flash and xD cards, a dual format offering flexibility but with slower write speeds compared to modern SD cards. The TG-320 uses standard SD/SDHC/SDXC cards, a more current and accessible format.

Connectivity and Extras

Neither camera is wireless-enabled - no Wi-Fi or Bluetooth. The TG-320 includes HDMI output for video playback, appealing to casual users. The E-3 sticks to USB 2.0 tethering.

Neither supports GPS, although newer models in each category would rectify that.

Price and Value Analysis

At around $670 (used market, reflective of 2008 pricing), the E-3 packed high-end DSLR features. The TG-320’s street price is negligible when new, often available very cheap second-hand, reflecting its casual target market.

Therefore, the decision isn’t so much price versus performance but matching the camera to your needs: rugged casual shooting versus advanced photography.
