In my garden, sheltered beneath the wheelbarrow -- it seemed like a nice little family scene...

Very nice! Which DOF you achieved with f/22? Besides, I found this nice site with interesting links for everyone who consider about depth of field and digital photography in general: DOFMaster

Thanks for comments, everybody!MacroLuv wrote:Very nice! Which DOF you achieved with f/22?
MacroLuv, according to DOFMaster, total DOF is about 1.7mm .
It's actually more like 2.5mm for this web-sized image, since fewer pixels corresponds to a larger circle of confusion (which DOFMaster won't let me set).
In any case, what my 300D gets at f/22 is about the same as your SP-320 would get at f/11, for this size subject. (The difference is due to sensor sizes, but I don't want to get into that swamp here.)
Trying to get more DOF by stopping down even farther would not be a good idea. At 1:1 and f/22, the image is already getting fuzzy from diffraction -- there's not much detail beyond what I posted. See here for more discussion & illustrations of resolution vs aperture for this lens at 1:1.
