A new UWA Leica M lens - the fastest UWA in M mount is shipping.
RF coupled, "close-to-zero" distortion according to Laowa, 110° angle of view, 12 elements in 9 groups, 2x ASPH elements + 3x ELD elements, 10 sunstars, 72mm filter thread, about 418g.
Priced at $649. Sample variations are a thing with Laowa, keep an eye on that. The diaphragm ring is going the opposite way, that surely is a minor nuisance. https://www.venuslens.net/product/laowa-15mm-f-2-zero-d-lm/
