Olympus SZ-31MR iHS vs Olympus Stylus 1s: A Deep Dive into Small Sensor Superzoom Cameras

When Olympus released the SZ-31MR iHS in early 2012 and followed up with the Stylus 1s (simply dubbed Olympus 1s) in 2015, they continued their intriguing journey in the small sensor superzoom category - a segment aiming to balance gear portability with useful zoom reach and some manual control. Almost four years separate these models, and the gap of technological advancements in that period allows for a fascinating comparison, especially for photographers seeking a compact, versatile camera without breaking bank or carrying heavy lenses.

Having spent extensive hands-on time with both cameras, including controlled lab tests and diverse field scenarios - from city streets and landscapes to casual wildlife snaps - I’ll unpack what differentiates these two Olympus offerings, along with where each excels and falters. This article targets serious enthusiasts and pros who want to understand real-world implications beyond spec sheets.

Readability Starts with Size and Handling: The Ergonomics Face-Off

At first glance, the Olympus SZ-31MR iHS screams compact point-and-shoot. Its pocket-friendly dimensions (106 x 69 x 40 mm, weighing just 226 grams) make it a reliable companion for travel and quick grab shots. The Stylus 1s, by contrast, adopts a bridge camera design with a DSLR-esque grip and body (116 x 87 x 57 mm, 402 grams), embodying a more substantial, confident presence in hand.

This size difference impacts handling significantly. The SZ-31MR iHS is easy to slip into a jacket pocket but offers minimal physical controls - no dedicated dials, no manual exposure modes, and limited grip area, which can challenge stability during extended shooting sessions. It’s a camera designed for quick, straightforward use with a single fixed lens.

Meanwhile, the Stylus 1s is heavier but ergonomically rewarding. It features a pronounced grip and more tactile controls - aperture and shutter priority modes, manual exposure, dedicated dials, and a customizable self-timer. If you value manual control or plan to shoot in varied lighting conditions, this gives the Stylus 1s a real edge.

The comparison is cleanly summed up in the layout overview:

The control complexity of the Stylus 1s is a testament to its hybrid role - bridging compact convenience with enthusiast-level manual options. For street shooting or spontaneous moments, the SZ-31MR’s simplicity can be a blessing. For deliberate composition and precise exposure control, the Stylus 1s wins hands down.

Sensor Size and Image Quality: The Heart of the Matter

Sensor technology defines much of the photographic potential here. Both cameras utilize BSI CMOS sensors but differ significantly in size and resolution.

The SZ-31MR’s 1/2.3" sensor measures 6.17 x 4.55 mm with a 16MP resolution (4608 x 3456 px), whereas the Stylus 1s’s larger 1/1.7" sensor at 7.44 x 5.58 mm packs 12MP (3968 x 2976 px). Despite lower nominal resolution, the Stylus 1s generally produces cleaner images with improved dynamic range and better low-light performance, thanks to larger photosites and superior sensor design.

From controlled lab tests and in-field shooting, I saw the Stylus 1s deliver richer detail retention, especially in shadows, with less noise at higher ISOs - useful for those tricky indoor or twilight sessions. The SZ-31MR’s smaller sensor struggles in dim light, and grain becomes noticeable beyond ISO 400-800.

As expected, the Stylus 1s also offers RAW support, allowing extensive post-processing flexibility - something the SZ-31MR lacks, limited to JPEG. For photographers prioritizing image quality and editing potential, this factor alone could justify the higher price.

Screen and Viewfinder: Seeing is Shooting

A camera’s LCD and viewfinder affect composition and usability, particularly in bright sunlight or for prolonged framing.

Both cameras feature 3-inch fixed screens, but with different tech and resolutions:

• SZ-31MR iHS: Fixed HyperCrystal III TFT LCD, 920k dots, touchscreen enabled.
• Stylus 1s: 3-inch tilting screen, 1040k dots, touchscreen enabled.

The tilting screen on the Stylus 1s is a significant practical advantage. It lets you shoot low to the ground or overhead without contorting your neck or compromising stability - a handy feature for macro work, street photography, or awkward angles.

Additionally, the Stylus 1s is the only one with an electronic viewfinder (EVF), boasting 1440k-dot resolution and nearly 100% coverage. This is a deal-maker for photographers who prefer eye-level shooting or require precise framing in bright light where LCD visibility suffers.

The SZ-31MR’s lack of a viewfinder means relying solely on the screen, which can frustrate in harsh outdoor lighting or when trying to stabilize for slow shutter speeds.

Zoom Range and Optics: Reach vs Aperture

Superzoom cameras often walk the tightrope between extensive zoom reach and optical quality. Olympus implements two very different strategies.

The SZ-31MR iHS offers a vast 25-600 mm equivalent zoom (24x optical), perfect for wildlife from a distance or detailed architectural shots. However, this comes at a cost: the variable aperture ranges from f/3.0 wide open to a rather narrow f/6.9 tele.

The Stylus 1s provides a shorter 28-300 mm (10.7x optical) zoom, but with a constant bright aperture of f/2.8 across the zoom range - exceptional for a fixed-lens superzoom.

How does this play out in practice?

The SZ-31MR’s extensive reach lets you crop in on distant subjects, but the light-gathering drops notably at telephoto, requiring faster shutter speeds or higher ISO. The image stabilization partially compensates, but even with sensor-shift IS, some motion blur sneaks in under lower light.

The Stylus 1s’s constant f/2.8 aperture enables better low-light shooting, shallower depth of field (for more creative bokeh), and faster autofocus due to increased light hitting the sensor. The trade is the shorter maximum zoom range, which might disappoint wildlife snappers needing serious reach.

Autofocus Performance: Speed, Accuracy, and Tracking

Autofocus (AF) capabilities shape usability across genres - sports, wildlife, street, or macro all demand different things.

The Stylus 1s is equipped with 35 AF points and supports continuous and face detection AF that worked reliably in diverse conditions during my testing. Its contrast-detection AF runs with commendable speed, exhibiting steady tracking even with moving subjects in daylight.

The SZ-31MR, though sporting basic contrast-detection AF as well, lacks the extensive AF point array and continuous AF modes, limiting its efficiency on moving subjects. AF was noticeably slower and more prone to hunting in low light or on fast-moving objects, a definite drawback for action shooters.

On continuous shooting, both cameras support about 7fps burst rates, but the Stylus 1s's buffer and sustained performance edge it out slightly thanks to better processor handling.

Image Stabilization and Macro Capability

Both cameras feature image stabilization, but their approaches differ:

• SZ-31MR iHS: Sensor-shift stabilization
• Stylus 1s: Optical image stabilization integrated in lens

The Stylus 1s’s optical stabilization delivers superior effectiveness, especially important at longer focal lengths and slower shutter speeds. It allowed me to shoot handheld at shutter speeds as low as 1/15s with minimal blur, an impressive feat for a superzoom.

Macro performance also favors the SZ-31MR on paper, with a remarkable 1 cm minimum focus distance versus 5 cm on the Stylus 1s. This allowed for very tight close-ups, though image sharpness at extreme macro distances was better on the Stylus 1s thanks to its better optics.

For users focused on close-up detail, the SZ-31MR’s macro function is a plus, but the 1 cm focus area can sometimes be tricky to nail sharp without a tripod or steady hand.

Video Features and Audio Recording

Both cameras capture Full HD 1080p video at 30fps, using MPEG-4 and H.264 codecs. The SZ-31MR limits video shooting to 30fps max, with no 4K or slow motion options - a reflection of its 2012 heritage.

The Stylus 1s matches 1080p 30fps video but brings additional recording features including timelapse capabilities, which may appeal to creative videographers.

Neither camera offers a microphone or headphone jack, which restricts serious audio control. Built-in mics suffice for casual recording but expect ambient noise and limited fidelity.

Neither camera supports 4K photo modes or advanced video codecs, so videographers wanting full-frame cinematic or high frame-rate performance should look elsewhere.

Connectivity, Storage, and Battery Life

Connectivity-wise, the SZ-31MR supports Eye-Fi cards for wireless transfer, a niche solution that requires specific SD cards. The Stylus 1s boasts built-in Wi-Fi, making file sharing and control via smartphone apps more straightforward.

Both cameras rely on standard SD cards (SDHC/SDXC), with single slots.

Battery life is a clear advantage for the Stylus 1s, rated at up to 450 shots per charge compared to around 200 for the SZ-31MR. For extended travel shoots or all-day sessions, the Stylus 1s’s endurance reduces the need for spares and charging breaks.

Real-World Image Quality and Sample Shots

Aside from specs, how do these cameras deliver in day-to-day photography? Image quality comparisons draw on my outdoor, indoor, and mixed lighting test shoots.
