A Detailed Comparison: Fujifilm GFX 100S vs Olympus OM-D E-M10 II

When choosing a camera, understanding the real-world implications of specs and features is crucial. Today, we compare two very different but popular mirrorless cameras from FujiFilm and Olympus, breaking down their strengths, weaknesses, and the photography styles each excels at. Whether you're a budding enthusiast or a seasoned pro weighing medium format against entry-level Micro Four Thirds, this thorough analysis will help you find the right fit.

Making Sense of Size and Handling in Practice

How a camera feels in your hands is often overlooked but profoundly impacts your shooting experience. The Fujifilm GFX 100S is a medium format powerhouse designed with professionals in mind, while the Olympus OM-D E-M10 II serves as an entry-level enthusiast camera, prioritizing portability.

• Fujifilm GFX 100S:
  • Measures 150 x 104 x 87 mm and weighs approximately 900 g.
  • SLR-style mirrorless design, robust build with weather sealing.
  • Larger grip and substantial body accommodate bigger lenses and extensive controls, enhancing stability for longer sessions or studio work.
• Olympus OM-D E-M10 II:
  • Compact dimensions of 120 x 83 x 47 mm and a lightweight 390 g body.
  • Also SLR-styled but noticeably smaller and lighter, designed for comfortable all-day carry.
  • Less aggressive ergonomics, but comes with a tilting touchscreen and modest control layout.

Our take:
If you value a substantial grip and weather-resistant construction for outdoor or professional use, the GFX 100S leads. For travel, street photography, or casual shoots where portability is king, Olympus is clearly easier on your shoulders.

Design Details at a Glance: Control and Usability

Beyond size, the camera’s top layout and button arrangement influence speed and intuitive usability. Professional shooters often favor direct, customizable controls over touchscreen reliance.

• Fujifilm GFX 100S:
  • Features a clean top plate with dedicated dials for ISO, shutter speed, and exposure compensation.
  • Large OLED EVF with 3.69M-dot resolution provides a crisp preview.
  • Touchscreen with 3.2-inch tilting functionality aids composition in challenging angles.
• Olympus OM-D E-M10 II:
  • More condensed controls with fewer dedicated dials, but retains customizable buttons.
  • Electronic viewfinder offers 2.36M-dot resolution, adequate for entry-level use.
  • 3.0-inch tilting touchscreen, though lower resolution than Fuji’s.

What this means:
The GFX 100S gives you more tactile control to adjust settings on the fly - a boon for studio and landscape work requiring precision. Olympus keeps it simple, accessible for beginners, but less ideal for rapid manual adjustments.

Sensor Size and Image Quality: The Defining Divide

Sensor size dramatically influences image quality, resolution, dynamic range, and low-light performance. Let's dive into the technical core.

• Fujifilm GFX 100S: Its medium format sensor stands out with a massive 102-megapixel count producing exceptional detail, wide color depth, and impressively smooth tonal gradations. The large sensor size enables outstanding dynamic range capturing intricate shadow and highlight detail, critical for commercial, landscape, and studio work.
• Olympus OM-D E-M10 II: The Micro Four Thirds sensor is smaller with 16 MP resolution. It performs well in good lighting, thanks to Olympus’s TruePic VII processor, but falls short in extremely low light and large print scenarios. The smaller sensor also results in a 2.1x crop factor, affecting field of view and depth-of-field characteristics.

In practice:
You can expect Fujifilm’s superior image quality to shine when pixel-level detail and color accuracy matter most. Olympus’s sensor is competitive within its class but best suited to social media prints and moderate enlargements.

Live View and Screen Versatility for Compositional Freedom

Both cameras use electronic viewfinders and vari-angle LCD screens to frame shots. How they perform here impacts your workflow, especially in street or travel photography.

• Fujifilm GFX 100S:
  • 3.2-inch tilting touchscreen with 2.36 million dots gives crisp previews and allows touch focus.
  • 0.77x magnification electronic viewfinder with a 3.69 million-dot resolution yields an almost optical-feel clarity.
• Olympus OM-D E-M10 II:
  • Slightly smaller 3-inch tilting touchscreen with 1.04 million dots.
  • 0.62x magnification EVF with 2.36 million dots is serviceable, but image clarity isn't as refined, especially in low light.

For interactive focus control and menu navigation, both touchscreens enhance ease, but Fuji’s superior resolution delivers a nuanced, faithful representation for critical focusing.

Real-World Image Gallery and Rendering Traits

Seeing is believing - how these cameras render skin tones, landscapes, and dynamic scenes tells us much about their character and suitability.

• Fujifilm GFX 100S: Rich color palette with creamy bokeh from large-format lenses. Skin tones appear natural and warm without oversaturation. Landscapes reveal exquisite shadow detail and minimal noise at higher ISOs. High-resolution files provide excellent cropping freedom for commercial prints.
• Olympus OM-D E-M10 II: Crisp images with respectable color accuracy. Less pronounced bokeh due to sensor size and lens aperture limitations. Fine shadow detail is occasionally lost in high contrast scenarios, and low-light images exhibit noticeable noise beyond ISO 1600.

Insight:
Medium format’s advantage becomes apparent in portraits and landscapes that demand maximum resolution and tonality. Olympus serves everyday shooting well but with visible limitations when pushing technical boundaries.

Autofocus: Precision, Speed, and Tracking

Autofocus systems ensure you get sharp images, especially crucial in wildlife, sports, and fast-moving subjects.

• Fujifilm GFX 100S: Employs hybrid autofocus with 425 points combining phase and contrast detection, yielding precise, reliable focus on static and slow subjects. Its lower continuous frame rate (5 fps) limits fast action capture.
• Olympus OM-D E-M10 II: Contrast-based AF with fewer points oversimplifies focus tracking but benefits from 8 fps burst for moderately fast subjects.

Testing notes:
For wildlife and sports, neither camera is a pro-fast-action specialist, but Olympus’s faster frame rate is an advantage. Fuji’s AF accuracy exceeds expectations in landscape and portraiture with careful composition.

Durability and Environmental Resistance

For adventure photographers and outdoor pros, robustness is non-negotiable.

• Fujifilm GFX 100S: Professionally weather sealed to resist dust and moderate rain, though not fully waterproof. Built to endure demanding shoots.
• Olympus OM-D E-M10 II: No official environmental sealing; avoid harsh conditions.

Lens Ecosystem and Compatibility

Lens choice defines creative versatility. The mount and native lenses showcase how each system meets your photography goals.

• Fujifilm GFX 100S: Uses Fuji’s G-mount medium format lenses, currently 13 native options available, ranging from wide-angle to super-telephoto. These lenses deliver exceptional sharpness and are optimized for the massive sensor.
• Olympus OM-D E-M10 II: Micro Four Thirds mount with an extensive line-up - over 100 lenses from Olympus, Panasonic, and third parties. Wide availability means greater affordability and adaptability.

What to consider:
If ultimate image quality and niche lenses attract you, Fuji’s medium format optics excel. For budget-conscious shooters who prioritize variety and compactness, Olympus leads.

Battery Endurance and Storage

Long shooting sessions demand reliable battery life and ample storage options.

Fuji’s higher-capacity battery and dual card slots provide peace of mind for critical shoots. Olympus's more modest battery life suits casual use but may require spares on day trips.

Connectivity and Multimedia Capabilities

Modern workflows demand seamless wireless and video features.

• Fujifilm GFX 100S:
  • Built-in Wi-Fi and Bluetooth for quick transfer and remote control.
  • Offers 4K video up to 30p in high-quality H.265 codec with external mic and headphone jacks for serious videographers.
• Olympus OM-D E-M10 II:
  • Built-in Wi-Fi only, no Bluetooth.
  • Full HD 1080p video recording maxing at 60 fps, no mic or headphone ports.

Video shooters: Fuji is the clear choice for filmmaking or vlogging with pro-grade inputs and superior codecs.
