The Yeenon helicoid came to the rescue. The Yeenon helicoid is nearly identical to the diameter of the Ortal 75mm f2 lens so they actually look really nice together, and they work wonderfully together as well. The only problem I have, is that the aperture ring is very large/wide, and it sits ahead of the focusing ring. Even after some use, I invariably turned the aperture ring when I really meant the focusing ring. Small niggle, but annoys me.
I am really liking this lens. Very sharp at f2 and with wonderfully saturated colours. Really looking forward to shooting with it more.
