You try go custom functions, check can set min and max shutter speed range and aperture range?
I know if there's this function, the default is:
- Aperture: min f/1.0, max f/91
- Shutter: min 30s, max 1/8000s
I think 7D should be can bah, it's quite a new model..
if you shoot street in bring day light, you can do ISO200, set min shutter 1/200s, then make use of EC. I think ISO200 with min 1/200s @ f/4 have rooms for play under board daylight![]()
tmr then try, going to zzz liao.

bright daylight, ISO 100 no problem, can hit 1/400s - 1/640s easily with f4.
