This lens looks interesting - in the Sony FE and Canon mounts the lens has 13 blade aperture (Nikon and Fuji versions only 7 blade aperture). What is most interesting is the lens will focus to 2:1 (twice life size) without a macro tube.
One question I have that's not answered in the article is whether the lens has full electronic hook up with a Sony body. The reason I ask is in a customer review of the Laowa 60mm macro it stated that his Sony cameras did not register the aperture. All lens are manual focus only and no IS which I consider non-essential in a macro lens since in almost all macro situations I'd be using a tripod.

The fundamental problem with Venus Optics Laowa lenses, at least in Sony mount, is that they are not chipped and have no electronic contacts so there is no EXIF info. Down the line, when you have forgotten, you will have no way of knowing what lens you took the photo with. It also means that there will be no lens profiles.

One of the lenses they introduced is a full frame 10-18mm lens - there is not a super wide lens in the world that doesn't suffer from some rectilinear distortion and significant light fall-off in the corners as well as some chromatic aberration...
