Fujifilm has taken a bold step in the world of medium-format cameras with the introduction of the GFX100RF, a compact and versatile camera that promises to replace nine cameras and four lenses with one relatively compact body. The GFX100RF is built around a 102MP sensor, the same as its flagship GFX100II, and features an innovative aspect ratio dial that allows users to choose from nine different formats to frame their image.

The aspect ratio dial is a game-changer for photographers, offering a level of flexibility that is unprecedented in a fixed-lens camera. The dial allows users to choose from a range of formats, including 4:3, 3:2, 16:9, and even a 65:24 panoramic ratio, which is an homage to Fujifilm's legendary TX-1 panoramic camera. This feature, combined with the camera's high-resolution sensor, makes it possible to crop and compose images in-camera, resulting in a more efficient and creative workflow.

In addition to its aspect ratio dial, the GFX100RF also features four digital "zoom" modes, which crop into the center of the sensor to deliver a different field of view. The camera offers 35mm, 45mm, 63mm, and 80mm options, which equate to about 28mm, 35mm, 50mm, and 63mm in full-frame terms. While these "zoom" modes do come at the cost of resolution, the resulting images are still of high quality, with the 80mm focal length cropped to 65x24 producing a 9MP image.

Despite its many innovations, the GFX100RF is not without its limitations. The camera's f/4 aperture feels restrictive, particularly in low-light conditions, and the lack of optical image stabilization may make handheld shooting more challenging. These limitations may be a result of Fujifilm's efforts to keep the camera compact and affordable, with a price tag of $4,899 that is still relatively expensive but cheaper than any other GFX body Fujifilm currently sells.

In comparison to Leica's full-frame Q3, the GFX100RF offers a more versatile aspect ratio dial and ultra-high resolution, but trades these features for a slower f/4 aperture and lack of image stabilization. Ultimately, the choice between these cameras will depend on the individual photographer's needs and preferences.

Overall, the Fujifilm GFX100RF is a remarkable camera that offers a level of flexibility and creativity that is unmatched in its class. While it may have its limitations, its innovative features and high-quality images make it a compelling option for photographers looking for a compact and versatile medium-format camera.
