Olympus SZ-16 iHS vs Panasonic Lumix DMC-GM1: A Hands-On Comparison of Two 2013 Classics

In a year brimming with photographic innovation, 2013 gifted us cameras spanning the budget-friendly all-in-one superzooms to the sleek, tech-forward mirrorless rangefinders. Among these, the Olympus SZ-16 iHS and the Panasonic Lumix DMC-GM1 stand out as intriguing - and vastly different - options targeting distinct types of photographers. I’ve spent a fair share of hours testing both, and in this deep dive, I’ll walk you through their strengths, quirks, and which user each might suit best.

Before we jump into pixels and zoom powers, let’s set the scene.

Size Matters: Pocketability vs. Grip

Right off the bat, these two cameras couldn’t be more different in design philosophy. The Olympus SZ-16 iHS is a compact superzoom point-and-shoot offering an impressive 25-600mm equivalent lens, whereas the Panasonic GM1 is a diminutive mirrorless camera, designed for enthusiasts who desire more manual control in a tiny package.

Looking at their physical dimensions and weight gives a quick insight:

The SZ-16 iHS (108x70x40 mm; 226g) feels chunky but solid in the hand - typical for a bridge camera housing a long zoom lens. The GM1, on the other hand, packs its Micro Four Thirds sensor and interchangeable lens mount into a rangefinder-style body barely larger than many compact cameras, weighing just 204g with no lens attached. As a personal test, I slipped the GM1 into a jacket pocket with a pancake lens attached - just effortless portability. The Olympus, not so much; more of a “grab a small bag” contender.

So for those who prize pocketability or minimalist travel, Panasonic edges ahead. But size is only part of the story.

Control and User Interface: A Tale of Two Cities… or Cameras

Looking at the cameras' top control layouts, the differences continue. The SZ-16 iHS is designed for simplicity and point-and-shoot ease, with minimal physical controls but some helpful dedicated zoom and shutter buttons. The GM1 embraces the mirrorless ethos of manual accessibility in a compact shell but with its own quirks.

The GM1 features a nicely tactile mode dial, shutter button, and customizable function buttons, albeit somewhat cramped due to size. Touchscreen operation on its fixed 3-inch LCD (1036k dots) supplements this, letting you peel through menus and even select focus points. Olympus offers a 3-inch TFT LCD (460k dots), fixed, without touchscreen - so an outdated feel for 2013 standards.

Ergonomically, the SZ-16’s bulk offers more grip confidence, particularly for extended shooting, while the GM1’s slim form demands a delicate touch or possibly an aftermarket grip for comfort. From a testing standpoint, I found the GM1’s UI more flexible for serious shooting but slightly fiddly for quick snaps without practice. Meanwhile, the Olympus delivers a no-nonsense user experience aimed at casual use.

Sensor and Image Quality: Do Bigger and Better Really Mean More?

Now we’re approaching the heart of the matter: image quality. The Olympus packs a 1/2.3-inch 16MP CMOS sensor - commonly found in compact cameras - whereas the Panasonic sports a much larger Four Thirds-sized sensor (17.3x13 mm), also at 16MP resolution.

This size difference is fundamental. Larger sensors gather more light, boast superior dynamic range, and generally produce cleaner images at high ISO. The Olympus sensor area clocks in around 28.1mm², dwarfed by the GM1’s 224.9mm² - an eightfold increase!

In practical use, this translated into noticeable differences. Olympus images were crisp and well-saturated in bright daylight, thanks to the camera’s inbuilt processing and intelligent auto modes. But shadows often crushed, and noise rose quickly beyond ISO 800, making it a challenge for low-light or night photography.

The Panasonic GM1, paired with Micro Four Thirds’s bigger sensor, held detail and tonal gradation impressively well up to ISO 1600-3200. Dynamic range was superior - helpful when capturing backlit landscapes or portraits with subtle shadow detail.

Speaking of portraits, both cameras offered face detection autofocus, but the GM1’s higher-fidelity sensor resulted in more natural skin tones and less digital artifacting, especially in challenging light.

Autofocus and Shooting Speed: Catching the Decisive Moment

Neither of these cameras are sports photography powerhouses, but autofocus performance is nonetheless crucial for everyday shooting.

The SZ-16 iHS employs a contrast-detection autofocus system with basic face detection but limited to single AF modes - no continuous tracking. The Panasonic GM1 steps up with 23 contrast-based AF points, selectable across the frame, plus face detection and contrast tracking that works during continuous shooting.

I found the GM1’s autofocus noticeably quicker and more reliable in varied lighting and moving subjects. Continuous shooting tops out at 5 frames per second, a respectable pace for its class. Olympus only manages 2 fps with basic AF lock between shots, making action or wildlife shooting quite limited.

Build Quality and Durability: Tough Enough?

Neither camera is ruggedized. Both lack weather sealing or dustproofing, making them best suited for fair-weather shooting or careful use. Neither is waterproof or shockproof.

Both are built primarily from plastic components, but the Olympus feels a hair sturdier due to its chunkier body. However, the Panasonic exudes a more premium finish overall and benefits from the build quality typical of Micro Four Thirds cameras.

For the traveler or outdoor enthusiast prone to rough handling, neither is the ideal choice if durability is a priority. But when paired with a weathersealed lens on the GM1, you get some flexibility.

Viewing and Composing: Screens Only, No Viewfinders

Interestingly, both cameras forego electronic viewfinders, pushing reliance onto their rear LCD screens.

The Olympus SZ-16 provides a 3" fixed TFT LCD with modest 460k-dot resolution and no touch capabilities - sufficient for framing but not much else.

Panasonic’s GM1 boasts a 3" TFT LCD with a higher 1036k-dot resolution and touch sensitivity, enabling tap-to-focus, swipe navigation, and a generally smoother user interface. The wide viewing angle is a boon outdoors.

I personally find an electronic viewfinder invaluable, especially under bright sunlight, so this is a mild disappointment for both from a professional or serious enthusiast perspective.

Lens Ecosystem: Fixed Zoom vs. Micro Four Thirds Versatility

A big consideration in any camera purchase is lens availability and compatibility.

Olympus SZ-16’s fixed superzoom lens ranges from 25-600 mm equivalent (24x zoom) with apertures from f/3.0 to f/6.9. This lens covers everything from wide landscapes to distant wildlife or sports - but with compromises.

Its superzoom lens lacks fast aperture or sharpness at long ends typical of such designs. Macro focus ability is absent, limiting close-up creativity.

In contrast, the Panasonic GM1 fits into the extensive Micro Four Thirds lens ecosystem - over 100 native lenses from Panasonic, Olympus, and third parties. This means you can pair the GM1 with fast primes for portraits, macro lenses, ultra-wides for landscapes, or telephotos for wildlife - tailoring your setup precisely.

The GM1’s lack of internal stabilization is a downside; you’ll want lenses with optical stabilization to compensate. Olympus compensates with sensor-shift stabilization.

Video Capabilities: Basic vs. Advanced

Both cameras shoot video, but the GM1 takes the lead here.

The SZ-16 shoots HD video at 1280×720 at 30fps in MPEG-4/H.264 formats with no manual control during filming. It lacks microphone input and advanced video features.

The Panasonic GM1 records Full HD 1920×1080 video at 60i/50i/24p and 720p at 60/50 fps in MPEG-4 and AVCHD. It allows greater control over exposure settings during filming but still no microphone input.

Neither supports 4K or advanced audio, but GM1 provides timelapse recording - a bonus for creatives.

Battery Life and Storage: Pretty Even Steady

Battery life favors the GM1 slightly - 230 shots per charge compared to SZ-16’s 220. Neither is stellar by today’s standards but enough for casual outings. Both use proprietary battery packs.

Storage options are identical: single SD/SDHC/SDXC card slots. Generous enough for typical shooting.

Wireless Connectivity and Extras

The Olympus SZ-16 iHS offers no wireless connections. No Wi-Fi or Bluetooth.

Panasonic GM1 includes built-in Wi-Fi, a key advantage for instant image transfer or remote control via smartphone apps - handy for social shooters.

Sample Images: Seeing is Believing

Let’s have a look at real-world captures from both cameras, shot in identical conditions and settings where feasible.
