The Venus Optics Laowa Aksen 45mm f/2.8 1-5x Ultra Macro APO Lens (Canon RF) is a specialized ultra-macro optic designed to capture extremely small subjects with exceptional detail. Offering a versatile 1:1 to 5:1 magnification range, the Aksen 45mm bridges traditional life-size macro photography and extreme high-magnification imaging, making it ideal for product details, insects, textures, scientific applications, and creative macro cinematography.
The lens maintains a consistent 1.6" working distance from the front of the lens throughout its magnification range, providing predictable spacing between the optics and your subject. This added working distance provides valuable room for positioning lights and working with delicate subjects while maintaining extreme magnification.
An internal parfocal zoom design helps maintain sharp focus as magnification is adjusted from 1x to 5x, simplifying composition and reducing the need for extensive refocusing between magnification settings. This makes the lens well suited for controlled studio setups as well as more flexible handheld shooting.
The APO optical design helps minimize chromatic aberration and color fringing, delivering cleaner edges, accurate color reproduction, and fine detail when photographing subjects at extreme close range. Its compact form factor also makes the lens easy to integrate with motorized focus-stacking rigs, where multiple images can be captured at different focus distances and combined for greater depth of field.
Combining 1-5x magnification, a consistent working distance, parfocal operation, and APO optical performance, the Laowa Aksen 45mm f/2.8 1-5x Ultra Macro APO Lens provides photographers and filmmakers with a versatile tool for exploring details far beyond the capabilities of conventional macro lenses.
Apochromatic Correction
The Aksen series is engineered to eliminate chromatic aberration, even at higher magnifications. The apochromatic correction effectively prevents color fringing, allowing you to capture more details and texture without distortion in your final image.
Parfocal Internal Zoom
Adjust your magnification without moving your camera or subject thanks to the innovative parfocal zoom design. The Aksen maintains sharp focus across the entire magnification range, while the internal zoom allows you to shift magnification without disturbing your lights or hitting your subject.Because the weight distribution also remains identical, this lens is ideal for videography as well as macro photography. Exposure changes are the only thing that needs to be compensated for as you magnify your subject.
Additional Details
- Eleven-blade diaphragm contributes to a pleasing focus falloff when using shallow depth of field.
- Standard focal length benefits the high magnification design by providing greater depth of field compared to telephoto or long lens designs.
- When adapting the Aksen to medium format cameras, there will be varying levels of vignetting depending on the magnification.
- Lightweight physical design makes the lens easier to use handheld and offers more room for illuminating subjects.
