Double Macro
After recently acquiring a second macro lens for my 5050 (thanks, Ryan!), I stacked them up together and spent 2½ hours on one dive practicing. All I can say is -- I love it!

This Leech Headshield slug was about ¾ of an inch in length. This is a full frame shot with no cropping. Considering the double-stacked macro lenses, I still think the 5050 has some amazing depth of field.
f/8 - 1/100sec - ISO 64.
Special thanks to Linda for pointing out this beautiful creature.

This very generous 2½-inch Flounder allowed me to approach it for this full-frame shot.
