Guitar Plectrum

100mm f 2.8 Macro + 250D close up lens at its maximum focus



damn DoF is soooo narrow (less than 1 mm) had to focus with live view as even with the better brighter view finder on the 40D I couldn't manual focus with that. even just a slight angle from the subject throws either side out of the DoF at f/6.3

still reasonably sharp compared to the 100mm f/2 with 250D close up lens
