Manufacturer description
Allows you to shoot without using the viewfinder. Small and exquisite, easy to carry. Good choice for documentary photography. The lens weighs 49g and adopts all-metal body design, compact and portable. Minimum focusing distance of 0.3m, focal length of 18mm, equivalent focal length of 27mm, it is very suitable for street photography and documentary shooting.
From the editor
Note that the lens does not have any controls as it has a fixed aperture of F/6.3, while the focus is fixed at 0.30m. The clock face on this lens is purely decorative.
As with any body cap lens, you shouldn't expect any outstanding image quality. The pedestrian speed of F/6.3 won't let you capture images in low light conditions without significantly increasing the ISO setting, which in turn can lead to digital noise and loss of sharpness in your photos. So if you have a desire to photograph a UFO, it is better to choose some other lens.
