My Iso is set at 100 - with auto Iso allowing it to be increased to a max of 1600.
Now, without flash if the Iso is incresed then this is indicated in the viewfinder. However, with flash the Iso does not seem to increase - maybe with flash it doesn't need to?
I didn't know the meter was reading ambient light, have to say thats a little confusing.
The flash is in-built and set to TTL, so I guess the camera will adjust the flash exposure to correctly expose?
Jeez, this flash thing is confusing especially for a newbie to DSLR's like me!
