The lens can be put into Macro mode at 80mm. It may be the correct lens isn't listed in the data base. The front of the lens has Sigma Zoom 28-80mm 1:3.5-5.6 II Macro
Amazingly crisp and colorful macro. You can get that good of macro with the Sigma 28-80 or did you use extension tubes in combination or some other method? Super cool photo!
