I have just mounted up 4 lenses was either gifted or bought for peanuts on the eBay mis-spelt list. The panels have proved to be my only expense really.
Anyway.. the process lenses all Agfa Intergons 150/210/270 f9 have 5 bladed apertures and the dallmeyer and zeiss tessar multi-bladed near circular. I have not had much use apart from a few polaroids in the house so far, as my car getting welded a lot, but how much have people seen a difference with the shape of apertures?
I know the wider the lens theoretically the less it should matter, but the Agfa lenses were from a process camera that was cost wise way in excess of anything normally purchased for standard camera use. Like the difference between zeiss still camera lenses and motion lenses. So will it effect the image, other than the OOF shaping?
I would like to note I am asking this as an " out of interest " question, I don't care about LPI or refractive indexes of lenses. Just does this number of blades really matter in truth of daily use?
