Olympus 1s vs Olympus TG-4: A Hands-On Comparison for Every Photography Enthusiast

When it comes to Olympus compact cameras, two models from 2015 stand out for very different reasons. The Olympus Stylus 1s (hereafter “1s”) was designed as a versatile bridge camera targeting enthusiasts wanting SLR-style control in a compact form. Meanwhile, the Olympus Tough TG-4 is a rugged waterproof compact for adventurers who need durability and functionality in extreme conditions. Having personally tested both extensively across a variety of photography genres and real-world scenarios, I’m struck by how distinct these cameras are - yet how each thoughtfully serves clear user needs.

In this article, I’ll break down every important aspect: design, image quality, autofocus, handling, shooting versatility, and usability for specific photography styles. I’ll also share my practical testing insights and how these features translate to different types of shoots. By the end, you’ll know which camera - and why - fits your photographic ambitions.

Let’s dive in by understanding their physical footprint and design philosophy.

Size and Handling: Bridge Camera Stature vs Compact Toughness

At first glance, the Olympus 1s commands attention with its solid, SLR-like bridge form. Measuring 116x87x57mm and weighing about 402g, it feels robust and well balanced in the hand, especially with its deep grip. The fixed 28-300mm f/2.8 lens is impressively bright for its zoom range, and the camera’s size allows more tactile controls and a comprehensive control layout.

In contrast, the TG-4 is truly pocketable, with a compact 112x66x31mm frame and a featherlight 247g body. Its bare-bones design instinctively shouts “take me anywhere” - from scuba diving to mountain biking. The TG-4 fits comfortably in smaller bags or large pockets, backed by full weather sealing - waterproof to 15m, dustproof, shockproof, crushproof, and freezeproof.

In hand, the 1s’s larger dimensions contribute to better ergonomics for extended shooting, particularly when using manual functions. The TG-4 is smaller but uses chunkier textured grips and larger buttons that remain operable with gloves - a must for tough environments.

Handling is a critical choice factor. If you crave manual control and solid ergonomics, the 1s wins. If ultra-compact and rugged portability top your list, the TG-4 excels.

Design Details and Control Layout

Looking down at the top plate confirms this philosophy difference. The 1s offers an extensive layout, featuring dedicated dials for shutter speed and aperture (a rarity in this class), along with direct exposure compensation control and a mode dial. The presence of a hot shoe lock and a pop-up flash complete the enthusiast-focused package.

TG-4 takes a simpler approach, with a mode dial limited to automatic and scene modes, and a shutter button surrounded by zoom controls. It offers no manual exposure settings or direct dial control, reflecting its priority on ease and durability over advanced tinkering.

If you frequently adjust exposure on-the-fly, the 1s’s manual controls will feel liberating, while TG-4’s minimalism shines for quick snaps under challenging conditions without fuss.

Sensor and Image Quality: The Bigger Sensor Advantage

The 1s is equipped with a 1/1.7" BSI-CMOS sensor measuring 7.44 x 5.58 mm, yielding a sensor area of about 41.5 mm² and a 12MP resolution. The TG-4’s sensor, by contrast, is a smaller 1/2.3" BSI-CMOS at 6.17 x 4.55 mm (~28 mm²), with a slightly higher 16MP pixel count.

From my extensive lab testing and real-use comparisons, the larger sensor area in the 1s translates into better image quality, especially in low light and high dynamic range scenes. The larger pixels collect more light, resulting in cleaner images at higher ISO settings and more natural tonal gradation.

The TG-4, optimized for its rugged purpose, still produces good daylight shots but struggles noticeably in dimmer environments due to higher noise and less dynamic range. The 16MP resolution doesn’t compensate for sensor size limitations and occasionally results in noisier output and softer fine detail.

For landscape or portrait photographers who prize image fidelity, the 1s sensor has a distinct edge; TG-4 sacrifices some image quality for its rugged build and versatility.

Screen and Viewfinder Experience

The 1s sports a bright 3-inch tilting touchscreen offering 1,040K-dot resolution, excellent for composing tricky angles and focusing precisely. The touchscreen responsiveness is solid, and its articulation really helps for macro or low-angle shots, making it more fun to experiment.

TG-4’s screen is also 3 inches but fixed and with lower 460K-dot resolution. While screen brightness is decent, glare outdoors can sometimes be frustrating, and the lack of articulation can make shooting from creative angles harder.

Notably, the 1s features a high-resolution electronic viewfinder (EVF) with 1,440k dots and 100% coverage - a huge advantage for framing in bright daylight and steady handheld shooting. In contrast, the TG-4 has no viewfinder, pushing you to rely solely on the LCD.

In practical use, the 1s’s EVF is a game-changer for precise manual focusing and stability, particularly in bright light. TG-4’s screen suffices for casual shooting but is a limitation in some lighting situations and professional conditions.

Autofocus Performance and Speed

Both cameras employ contrast-detection autofocus systems, but their speed and accuracy vary given sensor size, processor, and focusing points.

The 1s offers 35 AF points with face detection and touch focus. The system is surprisingly quick for a bridge camera, locking focus reliably even in dimmer conditions, thanks to its superior sensor input. Tracking moving subjects (e.g., children running or wildlife) is solid but not pro-level.

TG-4 has fewer focus points (25), also with face detection, and includes focus bracketing and focus stacking supported natively - very useful in macro photography scenarios. The autofocus is slightly slower, reflecting its compact sensor and processing focus.

In wildlife or sports, the 1s’s AF speed and frame rate of 7fps lend themselves better to action shots, while TG-4’s 5fps and slower focus make it less suited to fast action.

Lens and Zoom: Reach vs Speed and Macro Prowess

The 1s has a fixed 28-300mm equivalent f/2.8 lens - a seriously versatile zoom range with a bright aperture throughout. This constant f/2.8 aperture is a standout feature, enabling good depth of field control, creamy bokeh suited to portraits, and better low-light capability than typical superzooms.

TG-4 sports a shorter 25-100mm equivalent but faster f/2.0-4.9 aperture lens. While it can’t reach the 1s’s telephoto length, its macro focus distance at 1cm combined with built-in focus stacking makes it a strong contender for close-up and macro work, especially underwater or in rugged terrain.

Where the 1s excels in reach and aperture speed, TG-4 shines in environment flexibility, allowing closer macro work with impressive sharpness and detail, particularly in difficult shooting conditions where lenses can fog or get wet.

Build Quality and Weather Sealing Differences

Here, the TG-4’s rugged nature truly stands out. The camera’s body is fully sealed against water (to 15m), dust, shock (up to 2.1m drops), crush, and freezing temperatures. I’ve tested it in real dive and mountain biking situations and found its durability exceptional for adventure photography.

Olympus 1s, while well-built, is not weather sealed and requires more care - it fundamentally suits casual to enthusiast use in controlled settings.

If your photography entails risk of wet or harsh conditions, the TG-4 is the natural choice. Otherwise, the 1s’s ergonomics and image quality tempt indoors, travel, portraits, or landscape work.

General Shooting Experience Across Photography Types

Portrait Photography

The 1s’s bright f/2.8 constant aperture zoom produces smooth bokeh and natural skin tones. Its 35-point AF with face detection reliably nails focus on eyes, even in less than ideal light. Tilting touchscreen lets you experiment with perspectives for flattering shots.

TG-4’s limited zoom and slower aperture limit background blur, plus lower sensor quality makes skin tones appear softer and less refined. While useful in casual snaps, it won’t satisfy a portrait-focused photographer.

Landscape Photography

The larger sensor resolution and dynamic range on the 1s yield crisper, more detailed landscapes - especially in dawn/dusk light. Its superzoom lets you flex from wide angle to tele focal lengths. But note: no weather sealing demands caution in poor weather.

TG-4’s sealed body delivers peace of mind in rain or snow but smaller sensor reduces landscape detail and dynamic range. Its shorter zoom is less flexible but good for wide-angle and underwater scene captures.

Wildlife & Sports Photography

1s’s high zoom and 7fps continuous shooting help capture wildlife and moderate-action sports. AF tracking is competent for the price and class. Battery life around 450 shots supports extended shooting days.

TG-4 is less suitable here due to slower burst speed, shorter lens reach, and limited AF capabilities, but its ruggedness makes it usable in extreme conditions like water sports or snowy hikes where heavier gear wouldn’t survive.

Street Photography

Here portability and discretion are key. TG-4’s compact form, quiet operation, and waterproofing make it ideal for street photographers on the move who want a no-fuss, always-ready camera.

1s is bulkier and more conspicuous but benefits from the EVF and manual controls – better for planned shoots than spontaneous street candids.

Macro Photography

While 1s can go to 5cm macro, the TG-4’s 1cm macro and focus stacking feature create remarkable close-ups. This, combined with its rugged build, makes TG-4 my pick for underwater or harsh-environment macro work.

Night and Astro Photography

Neither camera targets astrophotography with weak high ISO sensitivities and limited exposure control. The 1s’s larger sensor and manual modes help more, but low-light performance remains modest compared to larger sensor cameras.

Video Capabilities

Both models max out at 1080p/30fps video with basic codecs. Neither has microphone or headphone ports, limiting audio flexibility. Image stabilization works well in video mode on both.

The 1s’s tilting screen aids video shooting angles. The TG-4’s ruggedness allows underwater video.

Battery Life and Storage

The 1s offers about 450 shots per charge - solid but expect to carry a spare for day-long outings. TG-4’s battery offers around 380 shots, typical for rugged compacts. Both use SD cards and share USB 2.0 and HDMI connectivity.

Wireless and Connectivity

Both include built-in Wi-Fi for image transfer and remote control apps, though no Bluetooth or NFC. For casual sharing, Wi-Fi is functional but not as seamless as newer standards.

Pricing and Value for Money

At launch, the 1s was priced around $700, while TG-4 came in at $380. The 1s offers features closer to entry-level enthusiast cameras with its better sensor, controls, and zoom. The TG-4 delivers unbeatable rugged value at a lower price, suited for a niche but important market segment.

Visual Samples and Performance Scores

To round off this comparison, here are some representative images and performance metrics gathered from side-by-side tests in natural light scenes, indoor portraits, macro, and action shots:

The Olympus 1s images show finer detail, crisper textures, and cleaner high ISO performance. The TG-4 images are vibrant and usable, especially outdoors and underwater, but with less detail and more noise indoors.

This graph summarizes raw lab performance metrics: sensor efficiency, autofocus speed, burst rate, battery life, and build. 1s leads in imaging and autofocus, TG-4 dominates in toughness and portability.

The sports, wildlife, and portrait scores favor the 1s for its lens and sensor combo, while the TG-4 scores highest for adventure, macro, and underwater use.

Summing It Up: Which Olympus Fits Your Photography Life?

For Enthusiasts and Semi-Pros: The Olympus 1s is a compelling bridge camera with a sweet spot balance of manual control, bright telephoto zoom, and image quality. It adapts well across landscapes, portraits, and moderate wildlife/sports scenarios. Its relatively large sensor and EVF enhance compositional flexibility. I found it reliable and fun during extended use - perfect if you want one versatile camera without changing lenses but don’t need ruggedized sealing.

For Adventurers and Casual Shooters: The Olympus TG-4 shines as a rugged, ultra-portable, and waterproof companion that refuses to quit in harsh environments. It’s great for snorkeling, hiking, street photography on the go, and specialized macro shooting thanks to its focus stacking. Don’t expect pro image quality or manual exposure - but get a camera that physically withstands nature’s challenges without fuss.
