Unless lighting levels are very low and flash is allowed, I usually stick with available light.
I usually use the 24L and 70-200 f2.8 IS MKII for the aisle walk. During the ceremony, I'll use several lenses depending on what I want to go for.
Typically I am at 1/160, f2.8, ISO2000-4000.
I've been thinking about using my 24L for the aisle walk. In a small venue, is this your main lens for this? I really prefer the 50 for the aisle, but it only works well with a pretty long aisle. So I usually end up using my 16-35, mostly at 35mm but I like to zoom out to 16mm at the end - I think it makes for a really cool image. That said, I don't know if it's that lens in general or just my copy but even at F/4 I get pretty soft results for aisle walk shots.
So short story long, you think I should try the 24?
