Finally i had time to simulate Zeiss Distagon bloated triangle aperture ( http://forum.hardware.fr/hfr/Photonumerique/Objectif/zeiss-distagon-rollei-sujet_19298_1.htm ). I took simple design 2.8/135mm Samyang lens and inserted triangular aperture behind front system, right above the aperture. Thus one still can fully use original aperture. I guess lens is now around 3/135mm and a bit sharper. I took it for a short walk yesterday. All shots wide-open (some a bit shaky).
