Last autumn the Kickstarter website successfully raised funds for the production of Funleader Cap Lens 18mm f/8.0. The authors of the project sent out the lenses in time by the participants of the fundraising, and now this product is available to everyone on the Funleader website.
The key advantage of the lens is its compactness – it hardly comes out of the camera. The optical layout of the lens includes six elements in four groups. The focal length is 18 mm and corresponds to a field of view angle of 100°, and the aperture is equal to f/8.
There is no need to focus – the lens is focused at the hyperfocal distance, which achieves a sharp image of all objects that get into the frame and are not closer than 0.8 m from the camera. To increase contrast and reduce the risk of flare and other artifacts used multi-layer coating. The body of the lens is made of aluminum alloy.
The 62mm diameter, 15mm length and approximately 80g weight lenses are available with Sony E, Canon RF, Fujifilm X, Nikon Z and Leica L mounts. Available on the company’s website for $150.
