Not really . The Camera focuses at the largest opening and then shifts to your setting .

It has to do with a lot of things - To put it kind of simple , the sensor is like a solar cell . It take a minium amount of light to work - produce electricity - AF needs that and rather than pixelate the shot , Canon sensors just won't turn on the AF till that voltage / setting is meat .

This is where the pin taping comes in . If enough light - might work , but most of time lenses will just hunt .

Looking to be corrected - soon
