It seems that between 7aritsans and TTArtisan, one will have a new lens out at least every week. Today it's the turn of 7artisans with its new 18mm f/5.6 optic. (note: this isn't to be confused with 7artisan's existing 18mm lens, which is an APS-C f/6.3 lens).
The new full-frame 18mm f/5.6 will be available in Sony E, Nikon Z, and L-mount versions and is exceptionally compact and light. The E-mount edition tips the scales at only 146g, while its 61mm diameter and 32mm depth pretty much qualify it as a pancake lens. Despite the low weight, the barrel and mount are made of metal, and inside is a 7-element optical stack arranged in 5 groups, containing two extra-low dispersion elements and an aspherical element. Focussing is possible down to 0.3m, with the 18mm focal length giving a 98.7-degree angle of view.
