Venus Optics Laowa 25mm f/2.8 2.5-5X Ultra Macro Lens for Sony E

Dedicated to extreme close-up imaging, the Sony
E-mount Laowa 25mm f/2.8 2.5-5X Ultra Macro from Venus Optics is a specialized macro lens for
photographing subjects at magnifications greater than life-size. Operating
within a 2.5:1 to 5:1 range, this lens has a minimum focus distance of just
6.8" at the 5:1 magnification along with a comfortable 1.6" working
distance. This range is benefitted by the wide-angle focal length, too, in
order to achieve greater depth of field compared to long focal length macro lenses.
Complementing the close-up capabilities, the optical design incorporates one
extra-low dispersion element to reduce color fringing and chromatic aberrations
for a high degree of clarity. Additionally, distinguishing itself from other
macro lenses, this 25mm f/2.8 is characterized by its notably sleek and
lightweight design for easier handling and more room to work with artificial
lighting.

 

Prime 25mm f/2.8 is designed for full-frame Sony E-mount
mirrorless cameras, however can also be used with APS-C models where it
provides a 37.5mm equivalent focal length.

 

Specifically developed for macro photography, this lens is
designed for use within a 2.5:1 to 5:1 magnification range for producing
greater-than-life-size imagery. This lens does not offer infinity focus.

 

When at 5:1 magnification, the lens has a minimum focusing
distance of 6.8" along with a working distance of 1.6", which affords
sufficient room for illuminating your subject. At the 2.5:1 position, a minimum
focusing distance of 9.2" is possible along with a working distance of
1.8".

 

Wide-angle design benefits the high magnification design by
providing greater depth of field compared to telephoto or long lens designs.

 

Manual focus operation for precise control over focusing
distance when working with close-up subjects.

 

One extra-low dispersion element greatly reduces chromatic
aberrations and color fringing for improved clarity and color accuracy.

 

Eight-blade diaphragm contributes to a pleasing out of focus
quality when using shallow depth of field.

 

Especially slim and lightweight physical design is easier to use
handheld and offers more room for illuminating
