This is a Chinese fast 50mm f/1.1 lens that is better known as Syoptic (aka Mr.Ding), sometimes as ARTRA LAB, Andoer, JABS, etc. But I have the unnamed [OEM] version of it.
The lens has a Voigtländer-style body with Sony FE/E mount. And it's a stated f/1.1 lens, and it's for full frame.
It only cost me $150. But now it's hard to find it on sale at that price. The lens is really has no name on the body, although it was sold as Vlogmagic.
Of course, this is a manual focus non-electronic lens.
The lens has a 52mm filter thread. The aperture has 11 blades:
The aperture ring has fixed [clicked] positions: f/1.1, f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/16 (note that there is no f/11).
Usually Chinese lenses are factory adjusted to focus beyond infinity (I think because of possible play in the focusing mechanism). Surprisingly, this lens focuses to infinity at the hard stop of the focus ring.
The lens has 8 elements in 6 groups:
(body with Leica M mount)
It comes with a threaded cap and a bayonet hood:
The lens itself is quite small for an f/1.1 (full-frame!) lens.
Comparison with the Юпитер-3 (Jupiter-3) 50/1.5 (with the adapter for Sony FE/E) and the Pentax K 50/1.4 (with the adapter for Sony FE/E):
First impressions are good. Of course, it is not as high performance as "sterile" modern expensive lenses. But it also doesn't produce a vintage look with lots of aberrations like older lenses. It's something in between.
There is the question of whether f/1.1 is the real thing. But in any case, I see this lens as an alternative to old f/1.4 film lenses.
