Fujifilm's medium format telephoto zoom — 79-158mm equiv at f/5.6 with OIS and weather resistance.
The Fujifilm GF 100-200mm f/5.6 R LM OIS WR was released in 2019 as the telephoto zoom for the Fujifilm GFX system, covering approximately 79-158mm full-frame equivalent on the 44×33mm sensor. Twenty elements in 13 groups including aspherical and Super ED elements. Nine rounded aperture blades. 67mm filter thread. At 1,050g. 5-stop OIS.
The optical design uses 20 elements in 13 groups (1 aspherical + 2 Super ED elements). Nine rounded aperture blades. The 67mm filter thread. At 1,050g the lens is moderate for a medium-format telephoto zoom. Minimum focus distance of 60cm (at 100mm) / 160cm (at 200mm). OIS rated 5 stops (CIPA). LM (linear motor) AF. WR weather/dust sealing. Variable aperture from f/5.6 at 100mm to f/5.6 at 200mm (constant f/5.6). GF mount.
The constant f/5.6 aperture reflects the medium-format sensor's depth-of-field characteristics: at 100-200mm on a 44×33mm sensor, f/5.6 provides depth of field equivalent to approximately f/3.6 on full-frame, maintaining useful subject separation for portrait and event photography. The 5-stop OIS compensates for the telephoto focal lengths where camera shake is most evident.
On the used market the Fujifilm GF 100-200mm f/5.6 R LM OIS WR is available at GFX telephoto zoom pricing. Condition checks: OIS engagement, LM AF response, WR sealing, 67mm front element for marks, zoom ring smoothness. Compatible with all Fujifilm GFX GF-mount medium-format bodies.
