Described as
"weird but genius," the Canon EF-mount Laowa 24mm f/14 Probe from Venus Optics is a truly unique lens designed for
close-up shooting. Distinguished by its long, slender lens barrel, this macro
lens provides a 2:1 maximum magnification with a 1.5' minimum focusing distance
and a close 0.8" minimum working distance. Even with such a close working
distance, the lens measures 1.3' long, placing you at a comfortable distance to
photograph nearby subjects. Also, as a wide-angle lens, greater depth of field
is afforded when compared to traditional telephoto macro lenses, which allows
for greater detail in the background with less subject isolation.
 The optical design includes both extra-low dispersion
and extra refractive index elements, which help to suppress chromatic and
spherical aberrations for a high degree of clarity, color accuracy, and
sharpness. Manual focus control permits focusing from 1.5' to infinity, and the
front of the lens has a built-in LED ring light to aid in focusing at close
distances. The slim 0.2" diameter of the front of the lens barrel also
offers greater opportunities for lighting subjects from the front.
Additionally, the front portion of the lens is waterproof, and permits working
with subjects just beneath the surface of water or in other dusty or trying
environments.
 Wide-angle prime is designed for full-frame Canon
EF-mount cameras, however can also be used with APS-C models where it will
provide a 38.4mm equivalent focal length.
 Unique macro lens design offers a
greater-than-life-size 2:1 maximum magnification along with a minimum focusing
distance of 1.5' and a working distance of just 0.8".
 The long, tubular lens barrel contributes to producing
a distinct bug-eye perspective and, despite the short working distance, the
length of the lens barrel places the camera at a comfortable shooting distance.
 Wide-angle 24mm focal length affords greater depth of
field and more surrounding detail than traditional telephoto macro designs,
which tend to isolate subject matter with shallow depth of field.
 Optical design includes two extra-low dispersion
elements that control color fringing and chromatic aberrations in order to
produce greater clarity and color accuracy. One extra refractive index element
is also featured, which reduces spherical aberrations and distortion for
improved sharpness and accurate rendering.
 Slim 0.8" front diameter allows performing unique
"slide-in" shots as well as affords a greater range of close-up,
inconspicuous shooting opportunities. The smaller front diameter also makes it
easier to illuminate close-up subjects from the front.
 The front of the lens is also waterproof, allowing you
to comfortably work just under the surface of water or in dusty environments.
 The front of the lens also has a built-in LED ring
light, which is powered via a micro-USB port on the barrel, to provide some
illumination on close-up subjects for easier focusing.
 Designed for use as a close-up, macro lens, the manual
focus operation also lets you focus at infinity.
 Seven-blade diaphragm contributes to a pleasing bokeh
quality.
