Finally done test of my focus shift problem. OPTAR 16mm @T1.3 and @Т2 and vintage OKS3-15-1 @ T2 for compare. Lens located about 50cm to the chart. DIY printed chart is A3 size. Lines smaller than 12 are printed with shifts and random mess so don't perceive it as perfect test example.
Also from these tests you can see how Mosaic OLPF works.
