Re: Sigma 150 first shot
by the last lens book I read (back in like 68) lenses are sharpest some at near there middle apertures. The reason seems to be that at the real small ones you are getting close to a pinhole and diffraction is taking over but at the larger it is the lens grind while at the very large the sides of the lens may have strain. -
