Product description Best SLR Lenses of 2017 Read More Dedicated to extreme close-up imaging, the Canon EF-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 Canon EF-mount DSLR cameras, however can also be used with APS-C models where it provides a 40mm 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 close-up subjects.
