DA 17-70 focusing behavior?
Feb 4, 2012

For those who have a DA 17-70 f4, does your lens often shows no sign of life when half pressing the shutter? I bought this lens and it often shows no response when I half press the shutter, especially in low light situations. When this happens I have to press and release the shutter few more times before it finally starts to show some focusing action. None of my other lenses behaves this way.

I was curious if this is the normal behavior of this lens.
