LENS ADAPTORS FOR CANON EF, EF-S, SONY E MOUNT, AND MFT CAMERAS ARE AVAILALBE. Described as "weird but genius," the Canon EF-mount Laowa 24mm f/14 Probe from Venus Optics is a truly unique lens designed for close-up shooting. Distinguished by its long, slender lens barrel, this macro lens provides a 2:1 maximum magnification with a 1.5' minimum focusing distance and a close 0.8" minimum working distance. Even with such a close working distance, the lens measures 1.3' long, placing you at a comfortable distance to photograph nearby subjects. Also, as a wide-angle lens, greater depth of field is afforded when compared to traditional telephoto macro lenses, which allows for greater detail in the background with less subject isolation.
