Lens Overview — Fujifilm 100mm f/4 EBC GX-M

The FUJINON 100mm F4 EBC GX-M is a prime lens built specifically for the Fuji GX680 medium format camera system. With a fixed focal length of 100mm and a maximum aperture of f/4, this manual-focus lens sits squarely in the standard focal length range for medium format photography, making it a natural choice for portraits, product work, and general studio shooting. As a medium format optic, it is engineered to cover the larger image circle demanded by the GX680 system, delivering the expansive detail and tonal depth that medium format is known for.

The lens is entirely manual focus, which suits the deliberate, methodical shooting style typical of medium format workflows. It accepts 77mm filters, a thread size common to many professional-grade lenses. Weighing in at 1,200g, this is a substantial piece of glass that reflects the build quality and optical engineering expected of a dedicated medium format prime.

The absence of image stabilization is standard for a lens of this era and format. For photographers already invested in the Fuji GX680 system, this 100mm prime represents a well-matched standard lens option that prioritizes optical integrity and image quality.

Key Features — Fujifilm 100mm f/4 EBC GX-M

Fuji GX680 Mount: Designed exclusively for the GX680 system, ensuring full mechanical compatibility with Fuji's large medium format camera.

EBC Coating: Fujifilm's Electron Beam Coating reduces flare and ghosting, supporting contrast and color accuracy across the image.

Medium Format Image Circle: Engineered to cover the large film plane of the GX680, delivering the fine detail and tonal depth medium format is known for.

Manual Focus Design: Fully manual operation suits the deliberate, methodical pace typical of medium format studio and field workflows.
