Metabones® Introduces Nikon G Lens to Fuji G-mount (GFX) Expander 1.26x
Introduces Nikon G Lens to Fuji G-mount (GFX) Expander 1.26x
! Petersburg, VA, :USA, Feb 21, 2020 Metabones® and Caldwell Photographic Inc. are pleased to
jointly announce the NF – GFX mount Expander 1.26x. It allows Nikon F mount lenses to be
mounted on Fujifilm GFX camera bodies without getting dark and / or soft corners. The
magnification factor of 1.26x perfectly matches the image circle of the full frame Nikon lenses to -
the medium-format sensor of the GFX series cameras, and therefore the diagonal FOV remains
The optical design consists of 5 elements in 3 groups, incorporating ultra- -high index Lanthanum
based optical glass as well as one element made of fused silica, resulting in extremely good
performances with professional grade f/2.8 zoom lenses. For example, a 24 70mm f/2.8 lens - -
becomes a 30 88mm f/3.5 zoom, and a 70 200mm f/2.8 lens b- - ecomes an 88-252mm f/3.5 zoom.
Please note that because of the nature of focal extenders, the aperture values decrease by 2/3 of a
stop; f/2.8 becomes f/3.5 and f/2 becomes f/2.5. High speed fixed focal length lenses such as the -
50mm f/1.4 will be transformed into a very fast standard lens 63mm f/1.8 for the GFX system.
The GFX mount Expander features Metabones’ unique manual G aperture adjustment mechanism,
which has the same angular throw distance as earlier Nikon Ai/AiS lenses, which features a
linearized f-stop adjustment as a function of aperture ring adjustment angle. The mechanism is
clickless in order to maximize its usefulness to cinematographers.
Metabones® Nikon G - GFX Expander 1.26x is available right now from the Metabones website and
its worldwide dealer network for US$519, and the adapteroptic-free version * will be available for
US$179, plus shipping and applicable taxes and duties.
*Limitation: Both Nikon full NOT-frame and DX lens may have enough coverage for the GFX cameras
when used in conjunction with the - - - . optic free adapter (MB_NFG FG BM1) Most of the case will result
strong vignetting or even black corners.
