Venus Optics has announced that the Laowa 85mm f/5.6 2x Ultra Macro APO it launched last year for Nikon Z, Canon RF, Sony E, and Leica M mounts is being released for Leica L-Mount, becoming the smallest 2x macro lens available for full-frame cameras.  It weighs 259 grams and is quite compact at just 8cm long by 5cm wide.

The lens features three extra-low dispersion elements that Venus Optics says eliminate color fringing at both in-focus and out-of-focus areas, which it claims allows the lens to render magnified photos with no chromatic aberration. It features also a seven-blade aperture diaphragm, an aperture range of f/5.6 through f/22, a 46mm front filter thread, and a minimum focusing distance of 16.3cm. The physical dimensions of the lens also do not change during use; that is to say, the front element does not extend outwards when the focus is changed which avoids collision with subjects and prevents dust from entering the lens.

Here are some sample pictures:
