You can mount the GFX on most 4x5 to get movements, with options in glass.
The problem is complex. The GFX simply pin on via an adapter (as Fuji offers it, for example) to a technical view camera is - for me - no solution. The sensor is then in most cases not in the swivel/rotation plane (former film plane). This means that when the sensor is swiveled, the sensor describes a circle and the focus moves. In the case of the Actus XL, the sensor of the GFX can be adjusted precisely in the swivel/rotation plane. Vertical and horizontal format changes are made by simple rotation. Most view cameras do not have a fine drive or it is not exact enough. My Sinar P2 had already a very good fine drive. The fine drive of the Actus XL is again much better and facilitates considerably the work with digital cameras.
The usual problem the short focal lengths on technical view camera are scarcely available is with the Actus XL by the Pentax 645 / Mamiya 645 + RZ / RB etc. Lens plates solved. Some of these lenses have a surprisingly large picture circle. For example, the Pentax 645 A 35mm F3.5 can be shifted almost 20mm, in any direction and rotate up to 12 degrees without a shading. Even the Pentax very rare Pentax 645 D FA 25mm F4 you can still 10mm shifts in any direction and up to 8 degrees (the Cambo Pentax 645 Lensplate, can also control lenses without aperture ring). Since short focal lengths generally require less adjustment, this is enough for me in most cases. Otherwise, you can also use all large-format lenses (Copal 0, 1, 3) and 4x5 stitches - which is quick and easy to do with the Actus XL.
I wonder if they make a adapter for RZ lenses. The RZ has a shift adapter and a 75 shift lens, as well as a very sharp 140
I use, for example, the Mamiya Seiko Macro M L-A 140mm F / 4.5 Macro II RZ 67 lens, with the Cambo RZ Lensplate in the studio on the Actus XL together with the GFX. The mutually independent adjustment distances of the front standard and the image standard cannot be reached with a tilt/shift adapter/lens. Therefore, comparisons between technical view cameras and tilt/shift adapters/lenses are only possible to a limited extent. It makes very well sense, which Cambo appropriate Lensplates offers synonymous if corresponding tilt/shift lenses should be available.
