Olympus Stylus 1s vs. Olympus Stylus Tough TG-870: A Hands-On Comparison for the Enthusiast Eye

When choosing a compact or bridge camera from Olympus, two models often surface - each with a distinct appeal. The Olympus Stylus 1s, announced in April 2015, and the Olympus Stylus Tough TG-870, introduced in January 2016, represent different philosophies in design and usage. I spent hours testing these cameras side-by-side across a variety of photographic disciplines to help you decide which one fits your workflow, experience, and budget.

In this detailed comparison, I will review technical nuances, real-world performance, and practical usability - drawing from extensive hands-on experience and standard camera evaluation protocols. Whether you crave the versatile reach of a superzoom or rugged reliability for adventurous shooting, this guide covers it all from sensor technology to ergonomics.

Form Factor and Handling: Grip Meets Portability

The Olympus Stylus 1s is a bridge camera with an SLR-like body, designed to deliver DSLR-style controls and ergonomics in a compact form. Meanwhile, the TG-870 is an ultracompact model, optimized for portability and durability rather than manual control.

The 1s measures 116x87x57mm and weighs 402g with battery - substantial enough for steady handling but still pocketable in larger coat pockets. Its pronounced grip, built-in electronic viewfinder (EVF), and extensive physical controls give you the tactile feedback many professionals crave. The tilting 3" touchscreen (1040k dots) complements manual focus ring and shutter speed dials for quick, intuitive operation.

In stark contrast, the TG-870 is smaller (113x64x28mm) and lighter at 221g, designed to disappear in a jacket pocket or backpack. While it offers a 3" tilting LCD (921k dots), it lacks an EVF and touch support, favoring simplicity over complexity. The control layout is minimalist, reflecting its ultracompact ethos and limited manual control (no aperture priority or manual exposure modes).

Thus, from an ergonomic and usability perspective:

• The Stylus 1s feels approachably professional, with dedicated dials conducive to rapid shooting and easy composition in bright conditions.
• The TG-870 is ideal for travel or activities where size and durability trump nuanced control.

Sensor and Image Quality: A Tale of Sizes and Resolutions

Sensor technology fundamentally shapes image quality. The 1s sports a 1/1.7" back-illuminated CMOS sensor with 12 megapixels, while the TG-870 houses a smaller 1/2.3" BSI CMOS sensor with 16 megapixels. Let's unpack what that means in practice.

Despite the higher pixel count on the TG-870, the larger sensor area of the 1s (41.52mm² vs. 28.07mm²) allows for larger photosites, yielding better noise control, dynamic range, and depth rendition. The 1s’s native ISO range starts at 100 and goes to 12,800, while the TG-870 starts at ISO 125 but tops at a native 6,400 with boost to 12,800.

In my side-by-side low-light tests, the 1s produced less noisy images with smoother tonal transitions up to ISO 3200. The TG-870's images are sharper in bright light thanks to the higher resolution but lose clarity and suffer from chroma noise under dim conditions. This disparity can affect portraiture (skin tones look more natural on the 1s) and low-light scenarios like night or indoor shooting.

Both cameras feature an anti-aliasing filter to balance resolution and moiré suppression, but the 1s's sensor size advantage fundamentally grants it superior image quality for demanding photography, especially where pixel-level fidelity or prints are concerned.

Sharpness and Versatility: Optical Systems Examined

The Stylus 1s continues the legacy of its predecessor with an impressive constant f/2.8 aperture zoom lens covering 28-300mm equivalent (10.7x zoom) with a 4.8x focal length multiplier. This constant aperture is rare in bridge cameras and gives real advantages in low light and shallow depth-of-field control.

The TG-870’s lens, while versatile, covers a shorter range: 21-105mm equivalent (5x zoom) with a variable aperture from f/3.5 to f/5.7. Its macro capability is excellent down to 1cm, enabling detailed close-ups, whereas the 1s focuses down to 5cm - a respectable but less extreme macro reach.

In handling telephoto situations such as wildlife or sports, the 1s’s longer reach and consistent aperture allow brighter, sharper capture with more background separation. The TG-870 wins for macros and close-range shooting in tricky environments, demonstrated by its durable build and impressive focusing accuracy at tiny distances.

Autofocus Performance: Tracking Speed Versus Simplicity

Both cameras employ contrast-detect autofocus systems, lacking phase-detection for blazing speeds but working adequately within their categories.

• The Stylus 1s features 35 AF points with face detection and 7 fps continuous burst shooting, supporting AF tracking modes. With its touchscreen AF and manual focus ring, focus precision and speed benefit from flexible control. In challenging tracking scenarios (wildlife, sports), the 1s maintains reasonably sharp focus provided the subject isn’t too erratic.

• The TG-870 offers continuous and single AF with face detection but fewer focus points, no touch AF, and slower AF acquisition in low light. It achieves a similar 7 fps burst rate but is typically suited to less dynamic subjects.

So, who scores better in autofocus? The Stylus 1s pulls ahead in precision and user control, making it more reliable for action photography. The TG-870’s autofocus is fine for casual shooting and adventures but occasionally hunts for focus under complex lighting.

Durability and Weather Sealing: Built for Different Worlds

This is where the TG-870 shines - Olympus’s rugged compact offering includes full weather, dustproof, shockproof, crushproof, and freezeproof capabilities. Rated for 10 ft drops, waterproof to 15m (50 ft) depth, it’s a tough companion for poolside, hiking, or extreme environments.

The 1s, handsome and robust but unsealed, does not have official weather resistance. It demands more environmental caution, and you won't want to expose it to rain or dust without protection. However, its solid construction and modest weight give it confidence in urban and studio settings.

If durability is your priority and you need a go-anywhere camera, the TG-870 is your choice. For controlled environments or when you want more control and quality, the 1s fits better.

Display and Viewfinder: Framing Your Shot

The Stylus 1s offers a 3-inch 1040k dot tilting touchscreen LCD and a 1440k dot electronic viewfinder - the latter being a great advantage in bright sunlight or for precise framing. The EVF covers 100% of the frame and provides a near-optical experience, which I found indispensable for accurate composition and during fast-paced shooting.

The TG-870 only has a 3-inch 921k dot LCD, tilting but not touch-enabled, and no viewfinder. This omission means composing in bright light can be challenging, and you'll rely heavily on the rear LCD.

Video Capabilities: Which Moves Better?

Both cameras shoot Full HD 1080p video, but there are differences worth noting.

• The 1s can record 1080p at 30fps, offering manual exposure modes and internal stabilization that make handheld video smoother and more controllable. Its audio capability is limited - no microphone or headphone ports - but for casual video, it offers respectable quality.

• The TG-870 steps up with 1080p 60fps support and a built-in LED illuminator for fill light in video mode, which is unusual and useful in dark settings. The lack of manual exposure control limits creative video use, but it remains capable for adventure videos where ruggedness is essential.

Neither camera offers 4K or advanced video features, so serious videographers would likely look elsewhere, but both deliver adequate video performance in their respective niches.

Sample Gallery: Images From the Field

To get a real sense of output, I assembled comparative sample shots under various conditions - daylight landscapes, indoor portraiture, macro close-ups, and night scenes.

In portraits, the Stylus 1s produced more natural skin tones and smoother bokeh from its longer focal length and brighter aperture. Landscapes taken with the 1s showed superior dynamic range and detail retention in shadows. For macro work, the TG-870’s 1cm minimum focus distance yielded evocative detail.

Low-light and night captures favored the 1s with less noise and cleaner exposures, while the TG-870, though grainier, impresses with its inherent ruggedness allowing creative freedom in hostile conditions.

Battery Life and Storage: Practical Shooting Considerations

The 1s uses the BLS-50 battery, providing approximately 450 shots per charge - a commendable number for a bridge camera with an EVF and complex controls. USB 2.0 connectivity supports modest file transfers, and the camera stores images on a single SD/SDHC/SDXC card slot.

The TG-870 uses Li-50B batteries, rated for around 300 shots per charge - less than the 1s, but respectable for an ultracompact. Interestingly, it offers internal storage alongside an SD card slot, giving you peace of mind against card failures. Both cameras feature built-in Wi-Fi for wireless sharing, though no Bluetooth or NFC is present.

The Lens Ecosystem and Expandability

Both cameras feature fixed lenses with no interchangeable options. This design limits long-term flexibility but aligns with their categories - compact point-and-shoot and bridge. The TG-870’s 5x zoom covers commonly desired focal lengths for travel and macro, while the 1s’s longer 10.7x zoom appeals to those wanting telephoto reach without swapping lenses.

Overall Performance Scores

Our exhaustive scoring, which accounts for image quality, autofocus, ergonomics, video, and usability, places the Stylus 1s slightly ahead overall. The gap is narrow and contextual, reflecting the 1s's versatility and image excellence versus the TG-870's ruggedness and compact convenience.
