The Canon RF-mount Laowa 25mm f/2.8 2.5-5X Ultra Macro lens, produced by Venus Optics, is specifically engineered for extreme close-up photography, allowing for the capture of subjects at magnifications exceeding life-size. This lens operates within a magnification range of 2.5:1 to 5:1, featuring a minimum focusing distance of merely 6.8 inches at the 5:1 magnification, while providing a comfortable working distance of 1.6 inches. The wide-angle focal length enhances this range, facilitating a greater depth of field in comparison to longer focal length macro lenses. To further enhance its close-up performance, the optical design includes an extra-low dispersion element, which minimizes color fringing and chromatic aberrations, ensuring exceptional clarity. Moreover, this 25mm f/2.8 lens stands out from other macro options due to its remarkably sleek and lightweight construction, which promotes easier handling and allows for more flexibility when utilizing artificial lighting.
- Prime 25mm f/2.8 is designed for full-frame Canon RF-mount mirrorless cameras.
- 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 close-up subjects.
