Upfront - I'm a newbie (sortof) with an expensive lens. So be gentle...
I have a Rebel T1i with a 24mm-70mm L2.8 USMI. Bought it because I wanted sharp pictures. Also thought that because of 2.8 I could take better pics in lower light without flash.
In Av Mode, I've noticed that in moderate light, afternoon shade, with 2.8 selected - it chooses a very slow shutter speed say 1/30 or more. If I pop the flash, it goes even slower. Does that sound right? Seems counter intuitive.
In the auto modes, it does vary speeds and apertures, as well as ISO.
In Tv mode, taking same pic at a faster speed 1/200, it will choose 2.8 and the pic is only slightly less exposed.
Am I just over my head with the lens or does it sound like something is wrong. Any diagnostics that anyone can suggest? Open to input/comments.
Thanks
