IronGlassAdapters Posted July 19, 2017 Share Posted July 19, 2017 There is two different modifications - first with one standart diaphragm, and second with two diaphragms - oval iris with stripe in the middle plus standart(blades). First one allows you to change angle of the flare line, created on a photo. Or you can use just fixed diaphragm. So, one or two diapragms - what is the best for you?
