Anastigmat Victar 50/2.9: With close focus (helicoid) adapter [1/2]

The Victar 50/2.9 shows triplet traits (see 1 and 2), but the limitation is that the minimum focusing distance is too long.

So I had to build an assembly: the lens, the M40x1-M42x1 ring, the M42x1-M39x1 adapter, two M39x1 5mm extension tubes, the M39x1-Leica M adapter, and the close focus (helicod) Leica M-Sony FE/E adapter.

It allows the minimum focusing distance to be shortened if necessary.

On the Sony a7c (FF, 24MP) I got the following result at f/2.9:
