Olympus E-510 vs Olympus Tough TG-2 iHS: A Hands-On Comparison for Enthusiasts and Pros

When diving into a camera purchase, the challenge isn’t just to pick a “good” model but to find the one truly suited to your photography style, needs, and environment. Today, I’ll share my detailed, experience-backed comparison between two Olympus cameras that might appeal to very different kinds of photographers: the Olympus E-510, a mid-size DSLR released back in 2007, and the Olympus Tough TG-2 iHS, a compact waterproof camera launched in 2013. Spoiler: These two cameras serve wildly different purposes despite sharing a brand and some overlapping features.

I’ve tested thousands of cameras and lenses across the years, so this article aims to unpack every meaningful detail - from sensor technologies to real-world performance across varied shooting scenarios - to help you pick the right fit confidently.

First Impressions: Size, Build, and Ergonomics

Physically, these cameras are in very different categories, reflecting their intended use cases.

The E-510 is a classic mid-size DSLR, built for photographers who want manual control and the ability to swap lenses. It weighs approximately 490 grams, measuring 136×92×68 mm, and features a robust grip that feels substantial without becoming unwieldy. Its body is crafted to provide a traditional DSLR feel – more serious and purposeful than a casual point-and-shoot.

The TG-2 iHS, by contrast, is a compact, ruggedized camera weighing just 230 grams, with a slim profile of 111×67×29 mm. Its build is waterproof (rated to a certain depth), crushproof, designed for outdoor adventure and extreme conditions. You won’t find a grip or interchangeable lenses here, but you will find a tough little camera ready for abuse, which you can toss in a backpack or pocket.

Looking at control layouts from above, the E-510’s multiple dials and buttons - shutter speed dial, exposure compensation, mode selections - make manual operation comfortable. The TG-2 opts for simplicity: fewer buttons, no manual aperture or shutter priority modes, but offers ease of use under demanding conditions. The TG-2’s design emphasizes quick access with minimal fumbling, crucial when you’re mid-hike or underwater.

Bottom line: If handling and manual control is your priority, the E-510 is the clear winner. If you want a rugged, lightweight camera for travel or harsh conditions, TG-2’s construction and portability shine.

Sensor Technology and Image Quality: The Heart of the System

At the core of every camera is its sensor, dictating everything from dynamic range to noise behavior.

The Olympus E-510 uses a Four Thirds sized sensor, measuring 17.3 x 13 mm with a total sensor area of around 225 mm², and a resolution of 10 megapixels. Back in 2007, this was quite advanced for APS-C and Micro Four Thirds cameras - especially with a CMOS sensor combined with an anti-aliasing filter. The sensor offers excellent color depth (21.2 bits in DxO tests), a respectable dynamic range around 10 EV, and a usable ISO range up to 1600 native (boosted ISOs not implemented).

In contrast, the TG-2 iHS houses a small 1/2.3" BSI-CMOS sensor, just 6.17 x 4.55 mm (28 mm² area), with 12 megapixels. This tiny sensor is typical for compact cameras focused on portability and robustness rather than ultra-high image quality. Although it provides a higher max ISO of 6400, the smaller sensor struggles in noise control and dynamic range compared to the bigger Four Thirds sensor in the E-510.

From my testing knocking the pixels hard, the E-510 delivers cleaner images with deeper color fidelity and more detail in shadows and highlights, crucial in landscapes and portraits. The TG-2 produces decent quality in good light but introduces noise quickly once ISO climbs - typical for compact sensors.

Ergonomics and User Interface: Ease Meets Functionality

Stepping away from raw image specs, ergonomic design and UI heavily influence day-to-day shooting enjoyment.

The E-510 features a 2.5-inch fixed LCD with only 230k dots, which feels quite dated by today’s standards and can be limiting in bright daylight or for detailed menu navigation. Still, its optical pentamirror viewfinder with 95% coverage provides a direct through-the-lens look that serious shooters often prefer over LCD framing. On the other hand, the TG-2 sports a 3-inch OLED screen with 610k dots - bright and crisp, excellent for framing and reviewing images, especially outdoors.

Note the absence of touch capabilities in both, a sign of their respective eras. Neither camera supports touchscreen focusing or menus, which some might find frustrating in prolonged use.

The E-510’s physical controls include dedicated dials for shutter speed, aperture (in lens), and exposure compensation, plus a range of customizable buttons, enabling faster adjustments once you know your way around. The TG-2, designed for automated shooting and simplicity, offers mostly full-auto modes with some scene selections and custom white balance, but no manual exposure control.

Lens Ecosystem and Versatility

One of the greatest advantages of a DSLR system is the ability to leverage a broad lens lineup.

The E-510 sports a Four Thirds lens mount with a focal length multiplier of 2.1x, meaning a 25mm lens acts like about 52.5mm in full-frame terms - ideal for portraits and general use. Being an older lens mount, the Four Thirds system boasts roughly 45 lenses, ranging from ultrawide zooms and macro primes to super telephotos. This versatility is a huge advantage - perfect for photographers who want full creative control over framing and depth of field.

Conversely, the TG-2 offers a fixed zoom lens (25-100mm equivalent) with a bright f/2.0 aperture at wide end, tapering to f/4.9 at telephoto. With macro capability down to 1 cm, it’s great for close-ups and casual shooting but limited if you want specialized options like tilt-shift or ultra-fast primes.

If you envision growing your lens collection or experimenting with different optics - nothing compares to the E-510’s system. But if lens swapping isn’t your thing or you want a compact, all-in-one solution, the TG-2’s zoom will suffice.

Autofocus and Shooting Speed: Keeping Up with the Action

For many shooters, autofocus performance and burst speed determine whether you’ll “catch the moment” or miss it entirely.

The Olympus E-510 features a 3-point phase-detection autofocus system with some multi-area capabilities but lacks face or eye detection. Autofocus speed can be considered modest by today’s standards, with continuous AF and single AF modes, but not sophisticated tracking. It maxes out at 3 frames per second continuous shooting, so fast continuous action (like sports or wildlife) is challenging.

The TG-2 iHS packs contrast-detection autofocus with face detection and tracking modes, including animal eye AF (though specific animal detection is limited). The TG-2 shoots faster at 5 fps burst, facilitated by a smaller file size and simpler processing pipeline. Still, contrast detection autofocus in compact cameras tends to be slower and less reliable in low light.

In practice, I found the E-510’s autofocus better suited for static or mildly active scenes (portraits, landscapes), while the TG-2’s faster burst and tracking autofocus excelled for casual outdoor activities where durability counts more than pinpoint focusing precision.

Performance Across Photography Disciplines: Real-World Testing

Let’s dig into how both cameras perform across different photography genres, highlighting strengths and gaps.

Portrait Photography

When it comes to capturing skin tones and creating creamy bokeh effects that make subjects pop, sensor size, lens choice, and autofocus matter a lot.

The E-510’s Four Thirds sensor with specialized lenses delivers excellent skin tone reproduction, natural color rendition, and the ability to blur backgrounds thanks to aperture-prioritized lenses. Eye detection is not available, so manual focus precision helps here.

The TG-2, with its small sensor and fixed zoom, struggles to achieve true background separation, though it offers macro focus as close as 1 cm for interesting close portraits with environmental context.

Landscape Photography

Dynamic range and resolution are king here. The E-510’s 10 MP Four Thirds sensor provides roughly 10 stops of usable dynamic range - crucial for capturing details in shadows and skies simultaneously. Coupled with interchangeable wide-angle lenses this is a recipe for striking landscapes.

The TG-2’s small sensor and limited dynamic range lag behind, though its waterproofing and shock-resistance may appeal to those shooting in rugged environments like beaches, waterfalls, or dusty trails.

Wildlife and Sports Photography

For fast-moving subjects, autofocus tracking speed and burst rate are paramount.

The E-510’s modest 3-point AF system and 3 fps limit mean you’ll miss many critical moments in sports and wildlife action. Its telephoto capabilities depend on attached lenses, which can be expensive or bulky.

TG-2’s 5 fps burst and face tracking autofocus are better for casual wildlife or fast street photography, but the small sensor limits image quality and depth-of-field control.

Street and Travel Photography

Portability, discretion, and decent low-light performance help here.

The TG-2’s compact, rugged design, slim profile, and silent operation make it the go-to choice for street or travel - where you want to grab shots quickly without intimidating subjects.

The E-510 is larger and noisier, but its image quality shines when you have time and space to set up.

Macro and Close-Up Photography

With a macro focus range down to 1 cm, the TG-2 iHS excels for extreme close-ups, capturing intricate details of flowers, insects, or textures without additional accessories.

The E-510 relies on specialized macro lenses, which can produce superior results but carry extra cost and weight.

Night and Astro Photography

The E-510’s larger sensor and support for long exposures make it better suited for night and astrophotography. Although ISO 1600 is modest by today’s standards, low noise and better dynamic range than the TG-2 result in cleaner star shots and night landscapes.

The TG-2’s max shutter speed of 1/4 s limits its ability for astrophotography, but it does have a “night scene” mode to partially compensate.

Video Capabilities: Modern Features vs. Basic Recording

Despite being separated by 6 years of tech development, video remains a weak point for both.

The E-510 has no video recording capability, as video capture was not a standard feature in DSLRs in 2007.

The TG-2 provides 1080p Full HD video at 30 fps with H.264 compression, good for casual clips and travel videos. It lacks external microphone input and headphone jacks, lowering its appeal for professional videographers.

If video is a concern, the TG-2 is the better choice by default.

Battery Life and Storage Options

Battery life metrics are sparse, but the TG-2’s listed 350 shots per charge aligns with modern compact expectations. The E-510's battery type is unspecified here, but past experience suggests around 300-400 shots typical for DSLRs of its class.

Storage-wise, the E-510 supports both Compact Flash cards and xD picture cards, offering flexibility but requiring larger, more expensive CF cards. The TG-2 uses likely SD cards, more accessible today.

Connectivity and Additional Features

Neither camera offers Wi-Fi or Bluetooth, standard in modern devices, so you’ll rely on USB 2.0 for image offload and HDMI on the TG-2 for playback.

The TG-2 stands out with built-in GPS, great for geotagging outdoor adventures - a feature the E-510 lacks entirely.

Environmental sealing is a major difference: The TG-2 is ruggedized, crushproof, and waterproof, while the E-510 has no weather sealing and is susceptible to dust and moisture.

Price and Value: Budget and Practicality Considerations

The E-510, being an older DSLR, is currently priced around $550 new (historically, now mainly available used or refurbished). Adding lenses, batteries, and storage cards will push the investment higher. Its value centers on enthusiasts wanting manual control and an atomic Four Thirds ecosystem.

The TG-2 is cheaper at about $380 new (or its equivalent used price now), offering compactness, ruggedness, and good image quality for casual shooters who prioritize durability and convenience over manual control.

Scorecards: Summarizing Performance and Strengths

From the data, the E-510 scores higher for image quality, dynamic range, and professional features, while the TG-2 earns points for portability, durability, and usability in rugged outdoor scenarios.
