I recently purchased a brand new Canon Camera 50D. I set the mode dial to AV (Aperture priority), than as the book say if I turn the main dial to change the aperture setting, my shutter speed will also change. My question is why is my shutter speed reading in whole numbers 4, 6, 8, 10, etc etc or sometimes it read 1"3 etc etc when I turn the main dial to change to different aperture reading.?
I know a little about shutter speed so I was looking for numbers such as 1/8000, 1/6400, 1/5000 but instead getting those numbers above. I'm testing my new camera in my family room with the windows open to get good outside lighing. It's not really dark in my family room.
Can anyone clear this up for me?
