Hi Keith,

Yes, I think :-) What you want is to bump up the ISO so you can use a smaller aperature (larger number - which is confusing). F11 to F16 would give you pretty good depth of field for macro work without compromising the sharpness of the lens to much depending on what lens you are using. Of course it's always a trade off as the higher the ISO the more noise you pick up which can degrade image quality somewhat. But the Canons have always been pretty good at higher ISOs. But if you go beyond 800 you'll start to pick up some noise. It won't be horrible but maybe noticeable.
