Fujinon GFX Lens Roundup

This year, Fujifilm made their entrance into the Medium Format Digital Camera market with the launch of their GFX 50S Mirrorless Digital Camera
Fujifilm GFX 50S. This new system introduces a new all-electronic GF mount paired with a 44x33mm sensor has a crop-factor of 0.8X compared to full-frame. This is exactly the same sensor-size with 4:3 aspect-ratio as the Pentax 645Z Medium Format DSLR
Pentax 645Z. Along with the new mount - which requires completely new lenses - Fujifilm launched four high-performance Medium Format lenses designed for resolutions of to 100 megapixels. Later, Fujifilm added two new lenses to the lineup.

The 6 GF-mount lenses together cover a focal-range of 23 to 120mm, equivalent to 18 to 96mm in 35mm format. All lenses are fully weatherproof and freezeproof, just like the GFX 50S camera. This is a serious entrance into a rather small market of very pricey digital cameras. Due to its mirrorless design and short flange distance, the GF-mount is capable of using traditional Medium Format lenses with a suitable mechanical adaptor, although any digital function including autofocus will clearly be lost.

Given that Medium Format is such a niche market, the GFX system is designed for professional photographers first. All lenses are robustly made with large fly-by-wire focusing rings and a high-grade finish. These lens currently sell between $2300 and $3000 USD.
