For those who want to get macro photos without an expensive macro lens.
I just received this 3 dioptries ACHROMAT lens and mounted it on a simple 85 mm tele lens.
Simply free hand photos on the desk with available light.
photo without the achromat
photo with mounted achromat
photo is a 100 % crop from the second photo => full resolution.
the manual lens with the mounted achromat.
For sure you can use any other lens as well.
It works really fine.
