On my Canon G10, it seems that I can not have both Macro and Manual Focus active at the same time. Is this always true? When I do go to Manual Focus sometimes I can focus within few inches, and sometimes only 10 inches or so and out. I can't think of anything that has changed. So, for my new business, I need to be able to consistently be able to focus within four inches. Auto focus on Macro doesn't always work and Manual Focus doesn't always work.
