Hi! Sorry if this is a repeat, but I didn't find a thread of this nature in my searching. I'll kick it off with two pictures from today.
Rebel XTi, Sigma 150mm f/2.8 @ 5.6 1/100 ISO 400, not quite 1:1, but almost, hand-held.
Rebel XTi, Sigma 150mm f/2.8 @ 2.8 1/500, ISO 100, hand-held 1:1
Don't be technical about macro meaning 1:1 or greater!
