Hi!
I have a question about SINAR EXPOLUX SHUTTER. I found that this shutter has the wider aperture: f4
Will it affect on my Aero ektar-1, 178mm lens if I want to use f2.5 aperture on the lens? Why somebody has posted information that I will lose the f2,5 aperture value on the lens and it will not be possible to get an aperture wider than f4? It is big proble. Because only f2.5 has beautifull bokeh...
