I entered the world of photography through the gates of Canon equipment. My choice was primarily influenced by my dad. He shoots Canon and this way I can borrow some of his equipment and lenses. My Canon gear served me well for the best part of 15 years; but my last camera body purchase, EOS 5D MKII, was more than 11 years ago. It was time for an upgrade. I wanted a significant upgrade. Image quality was my primary aim. I wanted a camera that produced the best files, colors, and dynamic range. After thorough consideration, and consultation with photography friends, I decided to venture into the world of Fujifilm; specifically their medium-format range, the GFX System.
Obviously switching between camera brands is not a simple thing. Of course RAW files and images may feel different, but more importantly, the equipment itself is different. How to handle the camera body, how to navigate menus, and how to adjust exposures can feel very alien. Luckly for me, one year before my GFX purchase, I bought a fujifilm X100F digital compact. It loved the layout and got very comfortable using the camera. I was especially fond of the retro-styled dials that are signature fujifilm.
To my shock, fujifilm opted against using their signature layout and design in their “flashship” product; the GFX100. A very strange industrial engineering choice I must say. the GFX100 has the traditional fujifilm menus and interface, many of the traditional fujifilm buttons, but not the two top dials.
The camera is obviously larger than most mainstream DSLRs and Mirrorless cameras. It is slightly on the heavy side too. However, it feels very well designed in terms of ergonomics. It provides a secure grip in both horizontal and vertical orientations. Some of the buttons are however frustratingly small.

3rd party support and accessories
Unlike mainstream offerings from Canon, Nikon, or Sony (and to some extent Fujifilm’s X-series), the GFX system has very little 3rd party support in terms of lenses and accessories. There are very few non-fujifilm G-mount lenses on the market. Adaptors do exist for those who want to utilize some of their existing glass. I purchased an adaptor (Metabones EF-GFX Smart Adapter) to connect my existing EF lenses from Canon on the GFX100. The adaptor works great, autofocus is reliable and accurate, but AF speed is slightly slow compared to native G-mount lenses from Fujifilm.
ON THE FIELD
The GFX100 produce some of the best RAW files anywhere. The files, although very large in size, are rich in detail, color, and preserve incredibly wide dynamic ranges. Auto-focus is fast enough for most subjects, except extreme sports; where you will struggle to track subjects a little and your hit-rate will suffer quite a bit. I’m nost saying the GFX100 cannot do action sports, but It is certainly not on par with latest mirrorless offerings from Sony or Canon.
Weather sealing on both the GFX100 body, and GF lenses, is solid and will withstand the harshest of environments. IBIS works very well, and if you end up purchasing any of the OIS (Optical Imaging Stabilization) lenses, the outcome is even better. I have shot tack-sharp images handheld at 1/15s using the GFX100 and GF45-100mm OIS lens.
Battery life is average. It is not the best on the market, and certainly not the worst. Since the GFX100 natively takes two batteries; it can easily last you a good day’s worth of shooting (roughtly 300 to 400 images)
