first time I hear about it, here is the BH US link it says:

The lens is optimized for use on APS-C format sensors, where it will provide a 96mm equivalent focal length, and it can also be used on full-frame format DSLRs, however some vignetting may occur when focused at infinity

also

Manual focus and manual aperture setting design does not maintain any electronic communication with the camera.

made by the chinese company Anhui ChangGeng Optical Technology Company Limited (Venus Optics)

and a review on ephotozine

the clever thing is that the lens has its own extension tube in the body, which allows it reach the x2 magnification. When at this setting, the lens element is right at the front of the housing, and when focused to infinity for portraits etc., the glass retracts right to the back of the lens housing

Thank you for research.

I also just found favorable reviews for this strange lens.

You are welcome, its really a strange lens, if its quality is as good as the Samyang/Rokinon then it is a great lens.

Generally, Macro lenses are excellent lenses, I hope this one is not a exception. Its strictly manual focus.

The selling point is its 2X Magnification, but only at 2.5 inches. The other one is the 14 blade aperture, which might be a nice feature.

I'd prefer a longer focal length and working distance myself, otherwise, it seems to be at least as good as a old Manual Focus Nikkor Micro lens that can be had and adapted to Canon for under $100.

It has gotten good reviews on the macro forums. As for its ranking vis-a-vis other macro lenses, I haven't seen any info, but it really is a unique offering.

I have to say that the old manual 55mm f/3.5 AIS Nikkor 1:2 macro is decent, and not such a bad landscape lens either. The light weight is nice. 6D is a good camera for using vintage manual lenses.

I'm a big fan of my Sigma 150mm Macro, it still seems too short sometimes though, once you get used to the extra working distance it still seems like "not enough".
If someone would make a 200mm 2:1 Macro lens that would be amazing.
Or, heck, how about 300mm or 400mm, I have the tripod for it and it would be amazing to take macro shots without stooping down all the time.

For photography in general, the term "macro" is interesting and perplexing. Anyone know the real definition? Does it mean close-focusing only? Or 1:1 only? Or close-focusing with flat-field? Or superlative IQ at close distances? Or ? If you simply want close-focusing, then use an extension tube or CU lens. I often use extension tubes or CU lens with a good quality L-series lens for (what I consider) decent macro shots. My 77mm 500D CU lens is pretty sweet on my 300/4L IS. When photographing 3D items such as flowers, a true macro lens is probably overkill.

relating to Photography matter, the word Macro refers to large magnification (image magnification) of small objects.

The true Macro lens, has magnification 1x (life size), since the size of the projected image on the camera's sensor is the same size as the real object in nature. If a beetle measuring 24x36mm, his image projected on a full frame sensor, would fill the entire sensor.

In the case of this lens, a 2X magnification would make a small beetle size 12x18mm fill the entire image of a full frame sensor.

I guess you are looking for the Sigma 180 2.8 macro, add a 2x converter and you get a 360mm 5.6 2:1 macro as you were dreaming of. it's big, heavy and expensive, but most dreams are
