Probably a common question but from a strange source.
I am building a sync device for syncing flashbulbs to my Canon t4i.
Now the specs say that my camera has a manual focus shutter lag of 95ms and a prefocused lag of 75ms.
When using a wired remote, just a simple closure switch - not the dual switch the canon remote uses - does anyone know what the shutter lag would be? My instincts say it's manual focus, but testing is having issues with that theory.
