I'm a new owner (1 week) of a Canon 7D and a 28-135 USM lens. While experimenting and just shooting randomly, I was surprised to see my aperture setting (through the viewfinder) showing me a 2.8.
Is there anything I could have set via knobs or dials or custom functions which could account for that? I thought if a lens was 3.5-5.6, that you simply couldn't get a 2.8 reading on it.
I was in bed, in a room lit by 1 light, shooting at pictures on walls, furniture, and the TV when it happened.
This whole incident is throwing me and making me feel like I have no idea what I am doing.
