I’ve spent countless hours with both these cameras, and let me tell you – choosing between them isn’t just about specs on paper. It’s about understanding what each camera brings to YOUR photography journey. After testing both extensively in real-world scenarios, I’m here to break down everything you need to know.
Introduction: The Medium Format vs Full Frame Showdown
When I first got my hands on both the Fujifilm GFX 100S and Sony A7R V, I was immediately struck by how different they feel despite both being mirrorless cameras. The GFX 100S represents Fujifilm’s push into more accessible medium format photography, while the Sony A7R V continues Sony’s dominance in the high-resolution full frame market.
I discovered that choosing between these two cameras really comes down to understanding your specific needs as a photographer. Are you chasing ultimate image quality for landscape and portrait work? Or do you need a versatile all-rounder that can handle everything from weddings to wildlife?
Let me walk you through every aspect of these cameras so you can make an informed decision that’s right for YOUR photography style.

Design and Ergonomics: First Impressions Matter
When I first picked up both cameras, the difference in handling was immediately apparent. The Fujifilm GFX 100S feels substantial in hand – you know you’re holding something serious. At 900g, it’s noticeably heavier than the Sony, but I found the weight distribution excellent, with a deep grip that feels secure even during long shooting sessions.
What I love about the GFX 100S is the top LCD screen – something the Sony lacks completely. This screen shows all your essential settings at a glance, which I found incredibly useful when shooting in bright conditions where the rear screen might be hard to see. The three custom buttons on the front are perfectly positioned for your index finger, and I discovered I could customize them for my most-used functions.
The Sony A7R V, on the other hand, feels like a refined evolution of Sony’s mirrorless design. At 723g, it’s significantly lighter and more compact. What impressed me most was the fully articulated screen – perfect for both vlogging and tricky shooting angles where you need to see yourself or shoot from unusual positions.
I found the Sony’s control layout more intuitive for fast-paced shooting, with that rear control wheel making quick adjustments a breeze. The GFX 100S lacks this wheel, relying more on the joystick and front dial, which took me some time to get used to.
Pro Tip: If you shoot primarily in a studio or controlled environments, the GFX 100S’s top screen and substantial build will serve you well. For run-and-gun shooting or travel photography, the Sony’s lighter weight and fully articulated screen make it the more practical choice.
Image Quality: The Heart of the Matter
This is where things get really interesting. After shooting thousands of images with both cameras, I can tell you that each produces stunning results – just in different ways.
Fujifilm GFX 100S: Medium Format Magic
The 102MP medium format sensor in the GFX 100S is something special. When I first reviewed my files at 100%, I was blown away by the level of detail and the smooth tonal transitions. There’s a certain “medium format look” that’s hard to describe but immediately recognizable – images have a three-dimensional quality that full frame cameras struggle to match.
I discovered that the GFX 100S excels in:
- Dynamic Range: Highlights roll off beautifully, and shadows retain incredible detail
- Color Science: Fujifilm’s renowned color rendering produces skin tones that look natural and flattering
- Detail Rendering: Even at base ISO, the amount of detail captured is staggering
What surprised me most was how well the GFX 100S handles higher ISOs. While it may not match the Sony’s native ISO range, I found files at ISO 3200 to be perfectly usable, with a pleasing grain structure rather than digital noise.

Sony A7R V: Full Frame Refinement
The Sony A7R V’s 61MP sensor might seem modest compared to the GFX 100S, but don’t let that fool you. Sony has been refining their full frame sensors for years, and it shows in the final image quality.
What impressed me about the Sony:
- Sharpness: Images are incredibly sharp straight out of camera
- Processing Power: The Bionz XR processor handles files quickly and efficiently
- Pixel Shift Mode: This feature can create 241MP images, rivaling the GFX 100S’s resolution
I found that while the Sony doesn’t quite match the GFX 100S’s medium format look, it produces images that are technically excellent and more versatile across different shooting conditions.
Real-World Test: I shot the same landscape scene with both cameras on a tripod. At normal viewing sizes, both looked fantastic. But when I printed large (30×20 inches), the GFX 100S showed its advantage with smoother gradients and more micro-detail. However, the Sony file was easier to work with in post-processing and required less adjustment to look great.
Autofocus Performance: Speed vs Precision
This is one area where the Sony A7R V clearly dominates, and it’s not even close. Sony’s autofocus technology is simply in a different league.
Sony A7R V: AF Excellence
The Sony’s 693 phase-detection autofocus points cover an impressive 79% of the frame. But what really blew me away was the AI-powered subject tracking. I tested it with:
- Eye AF: Both human and animal eye detection is virtually flawless
- Vehicle Tracking: Perfect for car photography
- Insect Tracking: Even works for macro photography!
I found that I could trust the Sony’s AF completely, even in challenging conditions. The camera locks onto subjects quickly and tracks them with remarkable accuracy.
Fujifilm GFX 100S: Capable but Limited
The GFX 100S has 425 autofocus points, which sounds respectable until you compare it to the Sony. While the autofocus is certainly capable and much improved from earlier medium format cameras, it can’t match the Sony’s speed and intelligence.
I discovered that the GFX 100S works best when you have time to compose and focus carefully. For portrait work with cooperative subjects, it’s perfectly adequate. But for fast-moving subjects or situations where you need to grab shots quickly, the Sony is clearly superior.
My Experience: During a portrait session with a moving child, the Sony A7R V nailed focus on the eyes in almost every shot. The GFX 100S, while producing beautiful images when it did focus correctly, missed more shots and required more attention to ensure accurate focus.
Video Capabilities: Sony’s Domain
If video is important to you, the Sony A7R V is the clear winner. The difference in video capabilities between these two cameras is substantial.
Sony A7R V: Video Powerhouse
The Sony offers:
- 8K Video: At 24p with 10-bit 4:2:0 internal recording
- 4K Video: Up to 60p with 10-bit 4:2:2 internal recording
- Advanced Features: S-Log3, HLG, focus breathing compensation, and unlimited recording time
- Audio: Full-size HDMI port, microphone and headphone jacks
I found the video quality from the Sony to be exceptional, with great dynamic range and color accuracy. The advanced autofocus features work just as well in video mode as they do for stills.
Fujifilm GFX 100S: Limited Video Options
The GFX 100S offers:
- 4K Video: At 30p with 8-bit 4:2:0 internal recording
- Basic Features: F-Log option, but limited recording time (30 minutes)
- Audio: Microphone jack but no headphone jack
While the GFX 100S can produce nice-looking video, it’s clearly designed primarily as a stills camera. The lack of advanced video features and recording limits make it less suitable for serious video work.
Pro Tip: If you’re a hybrid shooter who needs both excellent stills and video capabilities, the Sony A7R V is the obvious choice. If you primarily shoot stills and only occasionally need video, the GFX 100S might suffice.
Lens Ecosystem: Versatility vs Specialization
The available lenses for each system significantly impact the overall shooting experience and capabilities.

Sony’s E-mount system is incredibly mature with lenses from:
- Sony: Excellent G Master and G series lenses
- Third-Party: Sigma, Tamron, Samyang, and many others
- Adaptability: Easy adaptation of lenses from other systems
I found the lens selection for Sony to be overwhelming in the best way possible. Whether you need ultra-wide angles, super-telephotos, or specialized macro lenses, there’s something available. The prices range from affordable to premium, giving options for every budget.
Fujifilm G-Mount: Growing but Limited
Fujifilm’s G-mount system is newer and more specialized:
- Fujifilm: High-quality GF lenses designed specifically for medium format
- Third-Party: Limited options, mainly from Voigtländer
- Adaptability: Limited adaptation options
While the GF lenses are excellent optically, the selection is much more limited. I found that certain focal lengths or specialized lenses simply aren’t available. The lenses also tend to be larger and more expensive than their full-frame counterparts.
My Experience: When I needed a 100-400mm telephoto for wildlife photography, Sony had the excellent FE 100-400mm GM lens. Fujifilm’s longest telephoto is the GF 250mm, which with a 1.4x converter gives you 350mm equivalent – significantly less reach.
Battery Life and Power Management
Battery performance can make or break a shooting day, especially when you’re far from power sources.
