LAOWA - Ultra macro lens 25 mm f / 2.8 2.5 -5 x:

Optics dedicated to Macro photo
Variable magnification between 2.5: 1 and 5: 1 (5x the actual size)
Durable all aluminum construction
Compact design (folded position 2.5: 1) and contained weight (400g)
Very low dispersion lens to reduce aberrations
Short focal length = need fewer images in Focus Stacking
Long working distance and small barrel for better lighting of the subject

In addition to the existing 60mm F2.8 2x Ultra-Macro, Laowa continues to meet the demand of macro photography enthusiasts looking for an optic offering an even higher magnification:

This 25mm F2.8 makes it possible to obtain a magnification between 2.5: 1 and 5: 1, or the possibility of photographing at 5 times the real size of the subject! Compatible full size and available in 4 frames, it remains easily transportable when folded and its weight remains bare. The presence of an ED glass lens limits the appearance of aberrations to conserve maximum detail. Due to its short focal length, this 25mm has a relatively long depth of field which allows to limit the number of shots to be stacked to obtain an entirely clear subject (focus stacking technique). Its design allows to keep an optical-subject distance of at least 4cm which, associated with a small lens barrel, facilitates the lighting of the small subject. A tripod collar is available as an option.
