Naive question here about getting faster shutter speeds...and one which counter-intuitively assumes larger aperture values (physically smaller lens openings) and higher speeds. Would it be possible to design a shutter which would allow for wide-open aperture for focus, and when the lens is again closed prior to exposure, a physical stop would then limit the amount that the shutter opens (for exposure) to a diameter which would coincide with what would be the minimal physical size appropriate to the set aperture value - meaning less shutter travel and therefore higher possible speeds? Possibly graduate this maximum speed to coincide with the specific choice of lens opening? Yeah, I know, this runs counter to common practice - but within certain limits it might be applicable? Hmmm...could need lots of light - kinda silly idea, I guess!
Or...maybe a shutter with two sets of blades - one set opens and the other one then closes...with the assumption being that as each set has only one direction, they could be more tightly sprung?
