FEATURES
Laowa 17mm F4 D-Dreamer is a mirrorless lens designed for Fuji
medium format system cameras. It gives a focal length of
13.5mm (35mm-equivalent) and 115° angle of view. It provides a
native lens option for medium format users without the need to
adapt lenses from other system.
Laowa lenses keep up with the highest requirements of ultra
wide angle lenses with the close-to-zero distortion design. It
includes 21 elements in 14 groups with one piece of aspherical
glass and three extra-low dispersion glasses to eliminate
chromatic aberration and distortion. It also helps to deliver
corner to corner sharpness for the medium format sensors.
The Frog Eye Coating, known as " FEC", is applied to the front
element of the lens, protecting it from water droplets and
smudges. Multi-layer low-reflective coatings are applied to each
glass element to eliminate ghosting and flare.
The metallic build design increases the durability of the lens,
providing a more reliable shooting experience for medium-for-
mat users.
A lens hood is attached to the front of the lens and a 86mm
circular filter thread is equipped.
PERCAUTIONS
Safety Precautions
Do not disassemble or modify the lens by yourself. If it is damaged
by external force, do not touch any exposed part of the lens.
Don't expose the lens to excessive heat such as direct sunshine
or a parked car as this may deform the lens elements and other
mechanism.
Close the front cap of the lens or prevent the lens from exposing
sunlight when it is not in use. The light reflected by the convex
lens gathering on a nearby object can cause fire.
Do not place the sun in the center of the frame when shooting
with backlight, sunlight focused on the camera when the sun is in
or close to the frame could cause a fire or damage to your eyes.
When shooting with the camera's built-in flash, the lens itself
may block the light and cause vignetting, an external flash is
recommended in such case.
