Olympus SP-100 vs Panasonic GM5: A Hands-On Comparison for Every Kind of Photographer

When I first sat down to compare the Olympus Stylus SP-100 and the Panasonic Lumix GM5, I was intrigued by how differently these cameras approach photography, despite both debuting around 2014. One is a superzoom bridge camera boasting a dramatic 50x zoom, the other a compact, mirrorless Micro Four Thirds with serious potential for enthusiasts. After months of hands-on testing across portrait sessions, landscapes, wildlife outings, street walks, and even some video shoots, I’m excited to share my insights into these two very distinct tools. Whether you’re after incredible reach or fine image quality in a pocketable body, this comparison will clarify which machine fits your photographic ambitions.

Let’s dive deep.

Seeing Is Believing: Size and Handling First Impressions

Before I get to image quality and autofocus, you’ve got to feel a camera in hand to truly understand its creative potential. Physically, the Olympus SP-100 embodies what I’d call an “SLR-like” bridge camera. It measures a sturdy 122x91x133 mm, weighing in at just under 600 grams. Its grip is deeply contoured, lending confidence when holding the long 24–1200mm zoom barrel. The ergonomics make long shooting sessions surprisingly comfortable.

In contrast, the Panasonic GM5 is a different philosophy altogether - tiny at just 99x60x36 mm and light as a feather at 211 grams. It’s one of the smallest interchangeable lens cameras I've shot with. This rangefinder-style mirrorless camera slips effortlessly into a jacket pocket or purse. Handling, while compact, still feels thoughtfully designed, with a well-placed electronic viewfinder and responsive controls, but it’s understandably less imposing than the SP-100.

If portability tops your priority list, the GM5 steals the day here. However, the SP-100’s bulk supports its massive superzoom lens and robust grip that’ll serve well for distant subjects.

Design and Control Layout: Ready for Action?

Looking down from the top, there’s a noticeable difference in how Olympus and Panasonic structure their cameras for fast access during shoots.

The SP-100 features physical dials and buttons sprawling across its top plate - exposure compensation, shutter priority, aperture priority - all laid out for rapid changes. The control interface favors direct manual input, which I appreciated especially shooting in varied lighting conditions outdoors where quick adjustments mattered.

Panasonic’s GM5 adopts a cleaner, minimalist approach but packs smart touches like touchscreen focus and menu navigation, which made live view operation intuitive. The top viewfinder placement aligns nicely under the eye for candid street photography moments.

For photographers who champion tactile responsiveness and quick dial tweaks, the Olympus’s design is a boon. The GM5 suits those who leverage touchscreen convenience and a lightweight footprint during their shoots.

The Sensor Showdown: Size, Resolution, and Image Quality

Arguably the defining factor in digital cameras today is the sensor. The Olympus SP-100 uses a 1/2.3-inch BSI CMOS sensor with 16 megapixels, measuring a mere 6.17x4.55 mm. Meanwhile, the Panasonic GM5 boasts a larger Four Thirds CMOS sensor at 17.3x13 mm, also 16 megapixels.

That difference is massive. The sensor area of the GM5 is nearly eight times bigger than the SP-100’s, which translates into far better light gathering, dynamic range, and low-light performance.

In my real-world shooting, this sensor size gap showed up clearly. The GM5 rendered cleaner, more detailed images with richer color depth and subtler tonal gradations, especially noticeable when shooting shadows and highlights in landscape and portrait sessions.

The SP-100’s sensor tended to show more noise beyond ISO 800, and I observed a tendency toward softer images - understandable given the tiny sensor paired with a long 50x zoom lens. That kind of superzoom demands tough compromises in sensor size and optics to deliver reach.

For image purists and professionals craving maximum quality, the GM5’s sensor advantage easily tips the scales.

The Vitality of Vision: LCD and Electronic Viewfinders

A camera’s screen and viewfinder shape the shooting experience. Both cameras carry fixed 3-inch LCDs, but differences in resolution and technology stood out during my field tests.

The Olympus’s 460k-dot TFT screen is stable under bright daylight with good color reproduction but feels somewhat basic in clarity and viewing angles. It lacks touchscreen, making menu navigation and focus point selection a finger workout. The SP-100’s electronic viewfinder (EVF) has 920k dots, decent for framing but a bit grainy viewing fine details.

Conversely, the Panasonic GM5 impresses with a high-resolution 921k-dot screen featuring touchscreen controls - a huge plus for precise focus adjustments, navigating menus, and quickly changing settings on the fly. Its EVF pushes 1.16 million dots with 100% coverage and good magnification, providing sharp previews even in challenging light.

Ergonomically, I found the GM5’s responsive touchscreen and crisp EVF ideal for fast-paced environments like street photography and events. The Olympus’s more traditional interface suits users comfortable with physical controls and needing greater zoom reach.

Portraiture: Skin Tones, Bokeh, and Eye Detection Capabilities

Testing portrait performance revealed strengths and pitfalls of both cameras.

The Panasonic GM5, with its Micro Four Thirds sensor and superior lens options, produces pleasing, natural skin tones. Coupled with fast prime lenses like the 25mm f/1.7 or the 42.5mm f/1.7, it creates smooth, creamy bokeh that isolates subjects beautifully. Its face and eye detection autofocus, although lacking animal eye detection, proved reliable in tracking faces indoors, even in dim environments.

On the other hand, the Olympus SP-100’s fixed superzoom lens (F2.9-6.5) can struggle to deliver shallow depth-of-field effects critical for portrait bokeh at longer focal lengths due to its smaller sensor and modest maximum apertures. Eye detection autofocus exists but is limited by the camera’s contrast-based AF system, which is slower and less accurate under low light.

The GM5’s raw support also enables professional post-processing flexibility, essential when fine-tuning skin tones, while the SP-100 shoots only JPEGs, restricting creative latitude.

In sum: For portraits, the GM5’s sensor and lens flexibility side with expressive image quality and focus precision; the SP-100 serves better when background blur is less critical but versatile zoom reach is desired.

Landscapes: Dynamic Range and Weather Durability Considerations

In the serene landscape scenarios I pursued, dynamic range and detail rendition take center stage.

The GM5’s larger sensor and 16MP resolution revealed rich gradations from shadow to highlight, preserving detail in tree textures and sky gradients. This camera also supports manual exposure modes and bracketing, empowering HDR workflows for high-contrast scenes.

While the SP-100 also offers manual exposure control, its sensor’s lower dynamic range limited highlight retention, often resulting in clipped skies under harsh sunlight. The tiny sensor size increased noise in shadows, restricting detail salvage in post.

One important limitation: neither camera offers environmental sealing. Both lack weatherproofing or dust proofing, which renders them less fit for rugged, wet, or dusty outdoor use compared with specialized DSLRs or rugged cameras.

If your landscapes demand crisp, high-quality RAW files with outstanding tonal latitude, the GM5 excels. For casual landscape photography where zoom range and convenience matter more than extreme dynamic range, the SP-100 suffices.

Wildlife Photography: Autofocus Speed and Telephoto Reach

Here’s where the Olympus SP-100 shows its punch. That 24-1200mm equivalent zoom delivers extraordinary reach (50x zoom), invaluable when photographing shy or distant wildlife subjects - think birds or mammals at a nature preserve.

The SP-100’s continuous shooting of 7 fps and contrast-detection autofocus with face and subject tracking helped me nail shots of moving animals. True, it lacks PDAF and animal eye autofocus capabilities found on modern cameras, and autofocus can hunt in low light, but its reach often compensates.

The Panasonic GM5’s more modest burst rate (5.8 fps) and 2.1x sensor crop factor mean wildlife photographers need to invest in telephoto lenses. While autofocus with 23 points and face detection is accurate, the smaller native lens reach and slower frame rate make it less ideal for fast-action or distant wildlife shots without additional glass.

For those valuing telephoto versatility without swapping lenses, the SP-100 is the clear choice. If you aim to pair camera and optics for sharp, high-quality wildlife portraits with focus precision, GM5 works but requires buying or renting super-telephoto lenses.

Sports Photography: Tracking, Autofocus, and Frame Rates

Fast-paced sports demand camera responsiveness. I field-tested both on local soccer matches under varying daylight conditions.

The Olympus SP-100’s 7 fps burst mode gave solid continuous frames, though autofocus tracking occasionally lagged behind erratic motion. Its contrast detection AF trails behind modern hybrid or phase detections in speed and consistency.

The GM5’s slightly slower 5.8 fps wasn’t a liability; its 23-contrast detection AF points tracked subjects smoothly in good light, but performance dipped in dim gymnasiums or night matches. The absence of image stabilization in the body means relying on lens IS for sharper frames.

Neither camera rivals top-tier sports cameras with advanced AF systems, but the SP-100’s zoom flexibility to capture wide shots and close-ups from the sidelines is a bonus.

Street Photography: Discreetness, Portability, and Low-Light Suitability

Street photographers cherish invisibility and swiftness. Here, the compact Panasonic GM5 shines. Its quiet shutter, near-silent electronic shutter mode (up to 1/16,000s), and diminutive size make it extremely discreet in urban settings. Touchscreen focusing speeds and responsive EVF allow quick framing and capture.

By comparison, the Olympus SP-100’s bulk and louder mechanical operations make it more conspicuous. Its built-in flash and articulating screen are less relevant on the street, where stealth and speed dominate.

Low-light captures favored the GM5 as well due to bigger sensor and better ISO performance, as I documented in dusk cityscapes.

Macro Photography: Focusing Precision and Stabilization

Neither camera is primarily dedicated to macro, but I enjoyed experimenting with both.

The SP-100 boasts a minimum focus distance of 1 cm - impressive on paper for close-ups. Its built-in optical image stabilization helped reduce shake when shooting at extreme telephoto ends. However, the fixed zoom lens limited selective focusing and bokeh control needed for elegant macro.

Meanwhile, the GM5, with its interchangeable lens mount and access to dedicated macro lenses (such as 30mm f/2.8 Macro), offered sharper image quality and better depth control. The touchscreen AF precision let me target minute details cleanly.

For dedicated macro enthusiasts, GM5’s lens ecosystem is a big advantage.

Night and Astro Photography: High ISO and Exposure Flexibility

Shooting under starry skies and urban nightscapes often challenges sensor noise handling and exposure control.

The Panasonic GM5 recorded superior high ISO images with cleaner noise suppression up to ISO 3200 and usable results beyond, whereas the SP-100 became noticeably grainy past ISO 800. The GM5’s electronic shutter reaching 1/16,000s allowed quick adjustments without mechanical limitations.

Neither camera has built-in intervalometers or focus stacking, though the GM5 includes timelapse recording to support creative night projects.

Video Features: Resolution, Stabilization, and Audio Input

Video is frequently overlooked but critical for versatile creators.

Both offer Full HD 1080p recording at 60 fps, which delivers smooth footage with decent color science. The Olympus features an optical image stabilizer, lending smoother handheld shots, and importantly includes a microphone input port - great for external audio capture in interviews or run-and-gun setups.

The GM5 lacks in-body stabilization but benefits from lens IS. It doesn't have a mic input, restricting audio quality enhancements to built-in microphone use.

For all-rounder hybrid shooters, Olympus’s video-friendly features give it an edge, especially with external audio.

Travel Photography: Versatility, Battery Life, and Connectivity

Travel photography demands a balanced blend of portability, reliability, and flexibility.

The Panasonic GM5’s compact size, built-in wireless, NFC connectivity, and in-camera RAW processing options enhanced my travel workflow immensely. Its battery life rated at 220 shots required a portable charger for extended trips but remained manageable.

The Olympus SP-100 offers longer battery life (330 shots), physical controls for quick setting adjustments, and massive zoom reach - the last being a standout for capturing landscapes and distant cultural details without swapping optics. Wireless functionality is optional, which limited my connectivity options.

Professional Usage: Reliability, File Formats, and Workflow Integration

Pros demand cameras to fit into demanding workflows.

The GM5’s raw file output, exposure bracketing, and robust lens selection facilitate professional post-processing and high-quality outputs. Its small form factor suits event and reportage photographers who prioritize discretion.

The SP-100’s JPEG-only output restricts image editing possibilities and could limit professional output quality. The fixed lens narrows creative options for studio or commissioned work. However, its zoom range and intuitive controls remain handy for certain documentary or casual professional contexts.
