I am trying to learn to use Av mode and experiment with various settings. One thing I have noticed is on Av mode, camera always increases ISO value. Same shot taken in automatic mode and Av mode get ISO value of 200 and 600 respectively. Is there any...
While checking the ISO settings, I came across the menu entry called Rate of change. What does rate of change do? I could not find any explanation in the manaul
The lense does not have a hood. What I have noticed by checking JPEG exif data is it happens only when focal length is 4MM. I don't see this effect in any other time. Do I still need to send camera for repair?
