Olympus E-M1 vs. Samsung ST6500: A Hands-On, Comprehensive Camera Comparison

In my 15+ years of professional camera testing, I've rarely encountered a comparison quite like this. On the one hand, we have the Olympus OM-D E-M1, a "pro mirrorless" Micro Four Thirds system camera released in 2013 that still commands respect in enthusiast circles. On the other, the Samsung ST6500, an ultra-compact point-and-shoot from early 2011 aimed at casual users.

These cameras sit at distinct corners of the photography universe - not just in features and tech, but in intended uses, form factors, and photographic ambitions. Yet, as someone who’s tried thousands of cameras, I know readers want honest, practical insights: What does each camera do best? Where do compromises bite? And how do they stack up for different photography styles and workflows?

Let’s dig in.

Size, Shape & Feel – First Impressions Matter

Size and ergonomics often define how a camera performs for you in real-world shooting - not just specs on paper.

The Olympus E-M1 sports a robust, SLR-style mirrorless body constructed for serious use. Measuring 130 x 94 x 63 mm and weighing about 497 grams with battery, it delivers a confident, sturdy feel in the hand. Olympus designed it with photographers in mind - pronounced grips, tactile dials, and an intuitive button layout for quick adjustments on the fly. Despite the Micro Four Thirds sensor, it feels like a professional tool built to endure day-long shoots.

Contrast that with the Samsung ST6500, an ultra-compact camera of 102 x 57 x 19 mm that slips neatly into any pocket. It’s far lighter and more discreet. While the ultra-slim profile is ideal for casual carry and impromptu street shots, the ergonomics are necessarily compromised. Shallow grips and smaller buttons mean you’ll miss the physical precision controls pro shooters expect.

In my time with both, the Olympus gave me the feeling of readiness and confidence. The Samsung’s compactness was liberating – perfect for travel snapshots and casual use, but a camera you’d rather not rely on for extended sessions or demanding projects.

Design and Control Layout – Hands-on Handling

How a camera feels in your hands controls your shooting speed and comfort.

Looking down at the top view of these two cameras illustrates their different philosophies perfectly:

The Olympus E-M1 reveals a plethora of dedicated dials for ISO, shutter speed, exposure compensation, and shooting modes - all within thumb and forefinger reach. Its electronic viewfinder propels the shooting experience to that of a traditional DSLR, with a 2.36M-dot EVF ensuring excellent clarity for composition. The tilting 3" touchscreen LCD with 1,037k dots provides a sharp live view and flexible shooting angles.

The Samsung ST6500, however, offers a minimalist layout with no viewfinder and a fixed 3" touchscreen of lower resolution (460k dots). Its button groupings are small and sparse, reflecting the typical ultra-compact user’s expectation of simple point-and-shoot operation, without manual overrides.

Of the two, I found the Olympus’s controls substantially more usable in real-world shooting conditions. Whether tracking fast action or delicately adjusting exposure for portraits, those tactile dials make a measurable difference. The Samsung simply can’t match those swift workflow benefits.

Sensor, Image Quality & Processing Power

Digging under the hood to sensor size, type, and imaging pipeline explains much about final output quality.

The Olympus E-M1 features a 17.3 x 13 mm Four Thirds-sized CMOS sensor with 16MP resolution, coupled with Olympus’s TruePIC VII processor, supporting 5-axis sensor stabilization. The sensor area measures 224.9 mm², a large leap from typical compact sensors, resulting in better dynamic range, improved noise control, and higher overall image fidelity.

Meanwhile, the Samsung ST6500 houses a tiny 6.08 x 4.56 mm 1/2.3" CCD sensor, also with 16MP resolution but drastically different performance due to physical size and technology, with only 27.72 mm² sensor area.

This difference translates directly into image quality differences I observed in low light and landscape photography. The Olympus’s native ISO range from 100-25600 provides flexibility and usable high-ISO performance with noise under control up to ISO 3200. The Samsung peaks at ISO 3200 but noise and detail degradation become obvious well before that point.

DxOMark ratings underline these findings: Olympus scores 73 overall with excellent color depth (23.0 bits) and dynamic range (12.7 EV), while Samsung is untested but known from experience to fall far behind compacts with small sensors.

Autofocus: Speed, Accuracy, and Versatility

For me, AF system performance is critical when reviewing cameras, especially across fast-moving genres like wildlife and sports.

The Olympus E-M1 utilizes a hybrid autofocus system combining 81 phase-detection points with contrast detection, capable of continuous AF, tracking, face and eye detection. It also supports focus bracketing and stacking, potent features for macro and landscape work.

The Samsung ST6500 relies solely on contrast detection AF with unknown focus points count, lacking face or eye detection, and no continuous or tracking capabilities.

In real use, I found the Olympus’s autofocus impressively fast and reliable, able to maintain focus even on erratic wildlife or athletes in motion. The Samsung simply can’t hold focus on moving subjects, making it a run-and-gun camera best for static or slow-paced scenes.

Burst Shooting and Shutter Performance

Action photographers depend on refresh rates and shutter response for capturing decisive moments.

The Olympus E-M1 offers 10 fps continuous shooting with full autofocus tracking, a great performance even by today’s standards, enabling capture of fleeting expressions and motion bursts.

The Samsung ST6500 doesn’t offer burst shooting modes, and shutter speeds max out at a relatively slow 1/2000 sec, compared with 1/8000 sec on the Olympus, limiting options in bright light or action with fast shutter needs.

Weather Sealing, Build Durability, and Reliability

Overview: Olympus built their E-M1 as a professional tool with extensive environmental sealing, resistant to dust, light rain, and cold conditions (freezeproof not officially guaranteed but more robust than average). This durability is reassuring for landscapes, outdoor sports, and travel photographers.

Samsung makes no such claims for the ST6500. It’s a typical consumer-grade pocket camera with no weather sealing or ruggedness – careful handling inside bags or on sunny days is advised.

Lens Ecosystem and Flexibility

No camera exists in isolation; lenses define creative possibilities.

Olympus’s Micro Four Thirds mount gives access to a rich ecosystem of over 107 lenses from Olympus and other brands like Panasonic, Sigma, and more. This includes fast primes, pro-grade telephotos, wide-angle landscape lenses, and macro optics - covering every genre with quality glass.

Samsung ST6500’s fixed lens ranges 26–130 mm equivalent (5x zoom), but limited to the built-in lens optics, restricting versatility drastically.

In practical terms, I often switch bodies for specific tasks, but the ability to match lens to shooting need - portrait bokeh, wildlife reach, macro detail - is an unstoppable advantage for Olympus users.

Video Capabilities: Moving Beyond Stills

Video continues to be a vital creative mode for many photographers.

The Olympus E-M1 shoots Full HD 1080p video at 30 fps with H.264 and MJPEG codecs, with external microphone input improving sound quality. While not 4K capable, the in-body sensor stabilization notably aids handheld footage smoothness.

The Samsung ST6500 tops out at 720p HD video, with no manual exposure control or external audio options. Stabilization is absent, and video quality is basic at best.

Battery Life and Storage

Battery stamina determines usability on location.

Olympus E-M1 uses the BLN-1 battery, good for approximately 350 shots per charge - modest for a pro camera but manageable with spares.

Samsung ST6500 battery specs are not detailed, but typical compacts of its era run 200-300 shots per charge max.

Both rely on a single SD/SDHC/SDXC card slot.

Photo Genres: Tested Performance Insights

To help photographers pick the right tool, I’ll give you a walkthrough of how each camera performs by genre, based on real-world tests:

Portrait Photography

The E-M1’s autofocus eye detection works well to lock in critical focus on eyes, producing sharp portraits with pleasant bokeh from fast lenses. Skin tones are rendered naturally with accurate color and tonal gradation.

The ST6500’s fixed lens and limited AF hinder precise framing and focus. Portrait backgrounds are flat with little subject separation.

Landscape Photography

Olympus’s dynamic range, resolution, and in-body stabilization allow for sharp, detailed landscapes even handheld. Weather sealing means trekking in challenging conditions won’t damage it.

Samsung’s sensor struggles with highlight retention and shadow detail, resulting in flatter images. No stabilization means tripods recommended.

Wildlife & Sports Photography

E-M1 excels with rapid burst rates, predictive AF tracking, and telephoto lens compatibility - capturing swift animals and athletes in motion reliably.

Samsung’s slower AF and lack of burst modes limit it to casual wildlife shots at best.

Street Photography

The Samsung’s tiny size and low weight shine for discrete street shooting in crowded places.

Olympus E-M1, while larger, remains manageable for street, offering superior control and image quality for those wanting creative control.

Macro Photography

Olympus supports focus stacking and bracketing for critical macro precision paired with macro-specific lenses, delivering stunning close-ups.

Samsung lacks such tools and magnification, thus less suited for macro work.

Night and Astro Photography

Low noise at high ISO and sensor stabilization make Olympus capable of nightscape and starfield photography.

Samsung’s noise and limited ISO range restrict low-light capabilities.

Travel Photography

Olympus offers great versatility with lenses and features, though bigger and heavier than compact cameras.

Samsung scores with size, making it easy to carry all day but sacrificing creative control and quality.

Price-to-Performance and Value Consideration

The Olympus E-M1 debuted around $799, reflecting its professional ambition. Its ongoing support in the Micro Four Thirds lineup and lens ecosystem maintain strong value, especially if you prioritize image quality and shooting versatility.

Samsung ST6500, marketed as a budget-friendly point-and-shoot, appeals to casual users or beginners seeking simplicity, portability, and modest photo needs. Prices today are low but reflective of its dated technology and limited capabilities.
