AhamB - you are a bit right concerning rokkor double lines - that is because i have modificate this particular rokkor in the same way as i did with 85 1.7 stf like blur( https://www.fredmiranda.com/forum/topic/701273/0#6314743 ). But i did this treatment in a very low amount of gradient aperture coating and the final effect is very subtle, because i want to leave the contrast at normal level.
