Shutter OFF/ON

Lonnie Bell · February 23rd, 2008, 07:32 AM

Hi all,
Allow me to display my ignorance. My EX1 purchase happens the second week of March, so until then - I'm one of your biggest voyeurs. And I have a question about the Shutter OFF/ON button. And this question doesn't pertain to the solving of the "rolling shutter problem", but rather towards it's intended use by the Sony engineers. What's it do? What are it's effects?

The dialing down/up shutter speeds in conjunction with opening/closing aperature induces are goals of exposure and DoF. And extreme shutters can induce effects like Gladiator & Private Ryan, but turning the shutter completely off - what's the effect?

I'm assuming manual controls over our cameras give us more control over exposure and DoF, so why would we disengage one - such as shutter? Does it mean the recorded look is completely video-ish with no film like nuances? does it allow for the maximum amount of light through? this has to induce a shallower depth of field at each f-stop? great for 35mm adapters which normally eat light? help me wrap my head around this if you will please?

Thanks,
Lonnie

I think this thread pretty well covers the question
