Boy, wouldn't that be nice? Mine goes much smaller, too. But it
probably won't work.
Smaller apertures give sharper images only up to a point, then
diffraction effects spoil things. I think F16 and F22 are about it
for useful apertures. I have a Bercovitz spreadsheet somewhere that
calculate this, but I am on my way to a birthday party. MINE!
Cheers,
