I’m taking night pictures with Canon EFS 18-135mm STM lens and EOS 450D body. I’ve noticed that when I’m trying to shoot distant objects and there is enough light for the AF to work the pictures come out nice and sharp. But sometimes AF is unable to lock on the right focus (too dark?) so I try manual focus. But even though I turn the focus ring all the way to „infinity” the pictures are very out of focus. Essentially using MF I can’t find the focus setting to make the picure sharp. But in the same distance to object but a bit brighter circumstances AF successfully finds the right focus.
Is this normal? Shouldn’t MF set all the way to infinity result in a sharp picture of distant objects? I’m trying to take a picture of an urban landscape at night. And yes, i’m using a tripod.
