A Fujifilm anunciou hoje novas objetivas para o sistema GFX:

Fujifilm has announced the GF30mm F5.6 T/S and GF110mm F5.6 T/S Macro: the first tilt/shift lenses developed exclusively for mirrorless cameras. And, they announced the GF55mm F1.7R WR, a new "standard" lens.


The GF 30mm F5.6 T/S is a 23.6mm equivalent tilt-shift lens ideal for architecture work, while the 110mm F5.6 T/S Macro is an 85mm equiv lens that lends itself more to product photography.

Both lenses are designed to deliver 85mm diameter image circles, allowing ±15mm shift. It can then tilt by ±8.5°. Both the tilt and shift mechanisms can be independently rotated by 90 degrees, allowing tilt or shift when shooting portrait or landscape with the choice of whether the tilt and shift operate in the same orientation. Both lenses include tilt and shift sensors, which report back the position of the lens to the camera (currently only supported by GFX 100 II but with firmware expected for other models).









The 30mm T/S includes three molded glass elements and three ED lenses, including one Super ED element, designed to correct distortion and CA without the need for software correction. It features both Nano GI and Nano lens coatings to keep ghosting and flare under control, and a screw-in front ring can be removed to add a large hood to further reduce unwanted flare.

The 110mm F5.6 T/S Macro features 11 elements in 9 groups, including one aspherical element and two ED elements. Despite the 'Macro' branding, the lens gives a maximum magnification of 0.5x at its 0.43m (16.9") minimum focus distance.

The GF30mm F5.6 T/S will have a recommended price of $3999, while the GF110mm F5.6 T/S Macro will retail for around $3499.

The GF55mm F1.7R WR is a perfect normal prime (whose focal length matches the diagonal of the sensor), equivalent to a 43mm F1.3 in full-frame terms. This makes it, alongside the GF 80mm F1.7, one of the brightest autofocus lenses ever for a medium format camera.

Its design features 14 elements in 10 groups, with two aspherical and two ED elements, which Fujifilm says helps to minimize axial chromatic aberrations and keep spherical aberration under control. It uses a DC motor and GMR (giant magnetoresistance) sensor to precisely monitor the position of the AF group for improved AF precision. It has a minimum focus distance of 0.5m (1.6'), weighs 790g (27.9oz) and is a fraction under 10cm (3.9") long.

The GF55mm F1.7R WR will sell for around $2299.
